U.S.-UK Free Trade Agreement: Prospects and Issues for Congress
Released: 2017-09-05T00:00:00

Summary:
Prospects for a bilateral free trade agreement (FTA) between the United States and the United Kingdom (UK) are of increasing interest for both sides. In a national referendum held on June 23, 2016, a majority of British voters supported the UK exiting the European Union (EU), a process known as "Brexit." The Brexit referendum has prompted calls from some Members of Congress and the Trump Administration to launch U.S.-UK FTA negotiations, though other Members have moderated their support with calls to ensure that such negotiations do not constrain the promotion of broader transatlantic trade relations. On January 27, 2017, President Trump and UK Prime Minister Theresa May discussed how the two sides could launch high-level talks and "lay the groundwork" for a future U.S.-UK FTA. In July, the two sides launched a U.S.-UK Trade and Investment Working Group to explore a possible post-Brexit FTA. Negotiations on a bilateral FTA between the United States and UK would represent a change in U.S. transatlantic trade policy, which under the Obama Administration had focused on negotiating a U.S.-EU Transatlantic Trade and Investment Partnership (T-TIP) FTA.
Formal U.S.-UK FTA negotiations cannot start immediately. On March 29, 2017, Prime Minister May sent a letter to the European Council notifying it of the UK's intention to leave the EU. This triggered the two-year Article 50 exit process under the Treaty of the European Union. Until the UK formally exits, it remains a member of the EU, which retains exclusive competence over trade negotiations. During this time, and in the absence of any preferential trade agreement between the United States and the EU, World Trade Organization (WTO) parameters continue to govern U.S.-UK trade—as they do for U.S. trade with all other EU member states. In the meantime, the United States and the UK could pursue preliminary "informal" discussions on a potential bilateral FTA.
The prospects for a future U.S.-UK FTA depend on a number of variables, including the terms of the UK's negotiated withdrawal from, and future trade relationship with, the EU, as well as the UK's redefined terms of trade within the WTO. A U.S.-UK FTA could include reciprocal provisions to expand access to goods, services, agriculture, and government procurement markets; enhance and develop new bilateral trade-related rules and disciplines in areas such as intellectual property rights (IPR), investment, and digital trade; and cooperate on regulatory issues such as transparency and sector-specific concerns.
Congress has important legislative, oversight, and advisory responsibilities with respect to any potential U.S.-UK FTA. The U.S. Constitution grants Congress the power to regulate commerce with foreign nations. Congress also establishes overall U.S. trade negotiating objectives, which it updated in the 2015 Trade Promotion Authority (TPA) legislation (P.L. 114-26). In addition, Congress would face a decision on future implementing legislation for a final U.S.-UK FTA to enter into force. Under TPA, an FTA could be eligible to receive expedited legislative consideration if Congress determines that the FTA advances trade negotiating objectives and satisfies TPA's various other requirements, including notification to and consultations with Congress on the status of the negotiations.

subsections: section_title: Introduction
paragraphs: In a June 23, 2016, national referendum, a majority of British voters supported the United Kingdom (UK) exiting the European Union (EU), a process known as "Brexit." Since then, various Members of Congress have voiced support for launching U.S.-UK free trade agreement (FTA) negotiations, while other Members have moderated their support with calls to ensure that such negotiations do not undercut the promotion of broader U.S.-EU trade relations. President Donald Trump, since taking office, has continued to express support for Brexit, and stated his intention to nego tiate a U.S.-UK FTA "quickly" that is "[g]ood for both sides." During a meeting on January 27, 2017, President Trump and UK Prime Minister Theresa May discussed how the two sides could launch high-level talks and "lay the groundwork" for a future U.S.-UK FTA. In July, the two sides launched a U.S.-UK Trade and Investment Working Group to explore a possible post-Brexit FTA. 
U.S.-UK FTA negotiations would represent a change in U.S. transatlantic trade policy, which, under the Obama Administration, focused on negotiating a U.S.-EU Transatlantic Trade and Investment Partnership (T-TIP) FTA. Bilateral FTA negotiations also would represent a change from the Obama Administration's focus on multiparty regional negotiations, such as on T-TIP and notably the Trans-Pacific Partnership (TPP). At the same time, the United States and the UK have had long-standing trade ties. The United States has viewed the UK as a liberalizing force within the EU, and often has found itself more aligned with the UK on trade policy approaches than with the EU overall. 
At the same time, the notion of a U.S.-UK FTA is not new. For example, some policymakers expressed interest previously in exploring the possibility of the UK joining the North American Free Trade Agreement (NAFTA). More broadly, the notion of a "special relationship" between the United States and UK is long-standing.
Formal U.S.-UK FTA negotiations cannot start immediately. The UK is legally precluded from engaging in its own trade negotiations under its EU membership terms. On March 29, 2017, Prime Minister May sent a letter to the European Council notifying the body of the UK's intention to leave the EU. This action triggered the two-year Article 50 exit process under the Treaty on European Union. Until the UK completes what could be prolonged negotiations with the EU on its terms of withdrawal and formally exits, the UK remains a member of the EU, which retains competence over trade negotiations. So long as the UK is a member of the EU and in the absence of any preferential trade agreement between the United States and the EU, World Trade Organization (WTO) parameters continue to govern U.S.-UK trade—as they do for U.S. trade with all other EU member states. Meanwhile, the United States and the UK could pursue informal discussions on a potential bilateral FTA. 
Congress has important legislative, oversight, and advisory responsibilities regarding a potential U.S.-UK FTA. The role of Congress in U.S. trade policy is rooted in Article 1, Section 8, of the U.S. Constitution, which grants Congress the power to regulate commerce with foreign nations. Congress establishes overall U.S. trade negotiating objectives, which it updated in the 2015 Trade Promotion Authority (TPA) legislation ( P.L. 114-26 ). This grant of TPA is valid through 2021 (unless Congress enacts a possible extension disapproval resolution in 2018). Congress also would face a decision on future implementing legislation for a U.S.-UK FTA to enter into force. An FTA could receive expedited legislative consideration if Congress determines that it advances trade negotiating objectives in TPA and meets TPA's other requirements, including for the President to notify and consult with Congress on the status and content of the negotiations. 
section_title: U.S.-UK Trade and Investment Trends
paragraphs: The United States and the UK have a deep, extensive economic relationship. U.S. firms, large and small, are involved in U.S.-UK trade, directly and as a part of integrated supply chains. In 2016, U.S. goods and services exports to the UK totaled about $121 billion, and U.S. goods and services imports from the UK reached $107 billion, yielding a $15 billion U.S. trade surplus ( Figure 1 ). In terms of the EU, the UK accounted for about one-fifth of U.S. total trade with the EU-28, making it the United States' second-largest trading partner within the EU after Germany.
Globally, in goods trade, the UK ranked as the United States' fifth-largest export destination and seventh-largest source of imports. Top U.S. goods exports to the UK include civilian aircraft and parts, nonmonetary gold bullion (bulk gold before coining), pharmaceutical products, and art. Top U.S. imports from the UK include machines and machinery, motor vehicles, and pharmaceutical products. The UK is the United States' largest services trading partner, accounting for close to one-tenth of U.S. total trade in services and spanning sectors such as financial services, tourism, education, and business services. The United States is the UK's largest food and agricultural trading partner outside the EU for both exports and imports. While the U.S.-UK trade is significant and stands out in particular sectors, it is outweighed by U.S. trade with the rest of the EU ( Figure 2 ). 
Bilateral foreign direct investment (FDI) is also prominent in the relationship (see Figure 3 ). In recent years, U.S. and UK majority-owned multinational enterprises (MNEs) have employed over 2 million employees combined at their subsidiaries in each other's markets. In 2015, U.S.-UK FDI totaled $1.2 trillion, composed of $682 billion of U.S. outbound FDI and $556 billion of inbound FDI to the United States. The UK ranked as the second-largest destination for U.S. FDI abroad (the Netherlands being the largest), and the largest source of FDI in the United States (ahead of Japan). 
A number of industries stand out in the U.S.-UK investment relationship, notably finance and insurance, "professional, scientific, and technical" services, and manufacturing (particularly chemicals, transportation, equipment, and primary and fabricated metals). U.S. companies are attracted to the UK for its open business environment, workforce skills, and (current) access to the EU Single Market, among other things (see text box ). U.S. financial companies in the UK presently can take advantage of "passporting rights," through which they can set up a "hub" in the UK and then carry out their activities across the EU without having to establish a separate entity and/or obtain authorization in each individual member country. 
UK majority-owned MNEs with U.S. operations also play a role in U.S. trade. They represented $43.1 billion of U.S. exports of goods and $48.7 billion of U.S. imports of goods with affiliates in 2015. 
The United States and UK have had minimal trade frictions. However, the UK notably has been a part of the long-running U.S.-EU dispute in the WTO over subsidies to Boeing and Airbus.
section_title: U.S.-UK FTA Prospects
paragraphs: Brexit is expected to return authority to the UK to set its own external tariffs and its trade policy more broadly, a competence that currently resides with the EU for all EU member states. Formal U.S.-UK FTA negotiations, nevertheless, cannot start immediately. Article 50 of the Treaty on European Union (TEU) sets a two-year period for exit negotiations, although some analysts raise the possibility of the process taking longer. Until the UK completes what could be prolonged negotiations for its withdrawal from the EU and formally exits, the UK remains a member of the EU, and the EU continues to have exclusive competence over the UK's trade policy as it does for other EU member states—meaning that the EU negotiates a common trade policy with non-EU countries on behalf of (and with input from) its member states. In the meantime, the United States and the UK could pursue preliminary "informal" discussions. The line between "formal" and "informal" negotiations may be blurry, but moves such as exchanging tariff offers presumably would cross the line. A European Commission spokesperson described informal discussions as, "You can read the menu, but you can't order the food." 
subsections: section_title: Brexit Variables Affecting U.S.-UK FTA Prospects
paragraphs: Several variables in Brexit could affect prospects for a U.S.-UK FTA (see Figure 4 ). These include UK-EU negotiations on the UK's withdrawal from the EU, UK-EU negotiations on their trade relationship once the UK has formally exited the EU, and UK negotiations with other WTO members on its WTO schedule, as well as any transitional arrangements that the UK negotiates until final agreements in these areas are concluded. 
How long it takes to negotiate Brexit would affect when the UK is legally free to pursue formal FTA negotiations with the United States or other countries. The trade relationship that the UK negotiates with the EU could affect what positions the United States and the UK may take in their own bilateral FTA negotiations. Finally, the terms that the UK negotiates with the WTO could set a baseline for the U.S.-UK FTA negotiations, since U.S. FTAs traditionally have built on WTO terms and rules for enhanced market access.
subsections: section_title: UK-EU Trade Relations
paragraphs: The status of UK trade relations with the United States depends, to a large degree, on UK-EU trade relations going forward, as U.S. businesses that currently trade and invest with the UK benefit from the UK's access to the Single Market. Without clarity on the UK's internal market, it is difficult for U.S. negotiators to know the starting point for negotiating an FTA with the UK.
Future UK-EU trade relations, in turn, depend on the outcomes of two negotiations: (1) the terms of the UK's negotiated withdrawal from the EU under the two-year Article 50 process of the Treaty on European Union (TEU); and (2) UK-EU negotiations on their future trade relationship. Regarding sequencing, the UK favors conducting the negotiations about the UK-EU future partnership in parallel with the withdrawal negotiations. In contrast, the EU has stated that the withdrawal negotiations must precede the negotiations over trade relations.
From a trade policy perspective, Brexit presents the question of the extent to which, if at all, the UK would retain access to the Single Market for goods and services, as well as what EU regulations the UK chooses to retain, and the associated trade-offs. Such questions underscore the high level of integration between the UK and the EU-27; the EU is the UK's largest trading partner for both goods and services (see Figure 5 ), though its share has declined in recent years.
In a January 17, 2017, speech, Prime Minister May set out the British government's negotiating objectives and plan for exiting the EU. A February 2017 white paper subsequently released by the UK government elaborated on these positions. The Prime Minister confirmed that the UK is not seeking membership in the EU Single Market, but rather the negotiation of an FTA with the EU to allow "the freest possible trade in goods and services between Britain and the EU's member states" (see text box ). The Prime Minister further noted that
[the] agreement [between the UK and EU] may take in elements of current single market arrangements in certain areas—on the export of cars and lorries for example, or the freedom to provide financial services across national borders – as it makes no sense to start again from scratch when Britain and the remaining [m]ember [s]tates have adhered to the same rules for so many years.... 
At the same time, the Prime Minister left open the possibility of no trade agreement with the EU if negotiations between the UK and the EU do not lead to an acceptable outcome, saying "no deal for Britain is better than a bad deal for Britain." EU officials and some industry groups have pushed back on this view. Some have characterized scenarios of a negotiated UK-EU trade deal as a "soft" Brexit and the absence of such a deal as a "hard" Brexit.
The UK government also stated a goal of being able to pursue new trade agreements with other countries post-Brexit. The Prime Minister observed that "full [c]ustoms [u]nion membership," which binds the UK to the EU's common external tariff, prevents the UK from negotiating its own trade deals with other countries, and the white paper stated, "the UK will seek a new customs arrangement with the EU...." For some observers, questions arose over the extent to which the UK might remain a part of the EU customs union. Chancellor of the Exchequer Philip Hammond later confirmed that it is "clear" that the UK cannot stay in the customs union, as that would prevent the UK from independently negotiating its own trade deals outside of the EU.
On March 29, 2017, Prime Minister May triggered the two-year Article 50 process for withdrawal from the EU. June 2017 marked the start of the withdrawal negotiations. After reported infighting over how to implement Brexit, UK Cabinet ministers jointly affirmed the importance of a "time-limited" transition period to cushion Brexit's impact after the UK exits the EU, while underscoring that this period is not a way for the UK to stay in the EU "through the backdoor."
The EU has relatively low external tariffs on goods, but the UK may seek lower or no tariffs in certain sectors. Some observers expect the UK to focus on certain sectors in its trade negotiations with the EU given these sectors' high level of UK-EU integration, such as autos, chemicals, manufactured goods, and mineral fuels—sectors in which a large share of UK exports go to the EU. Financial services also may be a focal point (see text box ). Agriculture may be sensitive, given various interests and the EU's higher average tariffs on agricultural. 
In the meantime, in what may be a lengthy negotiation with the EU of its terms of withdrawal, the UK remains an EU member, and the EU continues to have exclusive competence over the UK's trade policy as it does for other EU member states. This precludes formal U.S.-UK FTA negotiations starting immediately, but does not preclude informal discussions.
section_title: UK Relations with the WTO
paragraphs: Another factor affecting U.S.-UK FTA prospects is any redefinition of the UK's commitments in the WTO, which would form the basis for any future trade relationships that the UK negotiates outside the EU, such as with the United States or other countries. Redefinition of the UK's terms in the WTO raises unprecedented issues for the WTO. 
The UK is a founding member of the WTO. It currently has WTO membership both on an individual basis and as a part of the EU. The UK's commitments to other WTO members presently are through the EU's schedule of commitments in the WTO. Transitioning to an independent position in the WTO will require the UK to negotiate new goods and services schedules on its WTO market access commitments (see text box ). The WTO, which currently has 164 members, operates on a consensus basis. Some aspects of the UK's WTO transition, such as establishing its most-favored-nation (MFN) tariff levels, may be relatively straightforward. The UK could "cut and paste" the EU's bound tariff rates to its own schedule, though, of course, the UK's internal economic and political dynamics may lead it to pursue different tariff levels. Establishing tariff-rate quotas (TRQs) may be more complicated, as doing so will require reallocation of the EU's quotas under the WTO. The EU maintains TRQs on products such as beef, poultry, dairy, cereals, rice, sugar, fruits, and vegetables. Other aspects include commitments under the Government Procurement Agreement (GPA), of which the UK is a member through its EU membership but is not currently a nation-state member. 
Some observers note that the UK may face difficulty securing approval from WTO members for its proposed schedule, pointing to the possibility that countries that have territorial disputes with the UK—such as Argentina over the Falkland Islands or Spain over Gibraltar—could use the WTO negotiation process as leverage to address these issues with the UK. Others say that any lack of formal approval ("certification") of the UK's proposed new schedule should not be a bar to the UK negotiating trade agreements with other countries. They note that the EU's schedule as the EU-28 has lacked full certification, and that has not stopped the EU from entering into FTAs. Under this view, so long as the UK does not make its trade terms more restrictive than the EU's schedule, it may not run afoul of WTO obligations.
In terms of sequencing, negotiations for UK's transition in the WTO could happen alongside UK withdrawal negotiations. According to UK's Secretary of State for International Trade Liam Fox, 
[i]n order to minimi[z]e disruption to global trade as we leave the EU, over the coming period the Government will prepare the necessary draft schedules which replicate as far as possible our current obligations. The Government will undertake this process in dialogue with the WTO membership. This work is a necessary part of our leaving the EU. It does not prejudge the outcome of the eventual UK-EU trading arrangement.
Meanwhile, the UK's WTO commitments remain as set out in the EU's schedules that apply to all EU member states until Brexit occurs.
In the absence of any preferential trade arrangement with a country, WTO terms would form the basis of the UK's trade relationship with that country. Since the United States and the EU do not have a n FTA with each other (T-TIP negotiations are on pause) , WTO terms already govern U.S. trade with the UK, as they do with other EU member countries. Those terms would continue to govern unless and until a U.S.-UK FTA is negotiated and enters into force. 
section_title: Specific Issues in Potential U.S.-UK FTA
paragraphs: Congress established U.S. trade negotiating objectives in the 2015 Trade Promotion Authority (TPA) legislation ( P.L. 114-26 ). U.S.-UK FTA negotiations, if launched in the next few years, presumably would be conducted under TPA. Such negotiating objectives, as well as TPA's notification and consultation requirements, would be expected to guide the administration's negotiations on a potential U.S.-UK FTA. 
Based on U.S. trade negotiating objectives, the past U.S. approach has been to negotiate comprehensive and high standard FTAs to liberalize trade and investment through reciprocal commitments to reduce and eliminate tariff and nontariff barriers in goods, services, and agriculture, as well as to establish trade rules and disciplines to govern trade among the parties. These commitments expand on WTO obligations and address new issues. 
Possible areas in U.S.-UK FTA negotiations are highlighted below. 
subsections: section_title: Market Access
paragraphs: Commitments to expand and enhance market access have been a core part of U.S. FTAs. Enhanced market access addresses a number of issues, including reducing and eliminating tariff and nontariff barriers. Tariff liberalization could be a component of a potential U.S.-UK FTA. Industrial tariffs applied by the United States and UK (through the EU's tariff schedule) are already relatively low (see Table 1 ), but higher in certain sensitive sectors. For instance, EU tariffs on automobiles are 10%. Expanding agricultural market access could be a key area of focus for the United States, given high EU average tariffs or tariff-rate quotas (TRQs) on products such as meat, fish, sugar, dairy products, soft drinks, and wine. 
It remains to be seen if a U.S.-UK FTA would face the same issues with respect to market access that confronted U.S. and EU negotiators in T-TIP. In those negotiations, the United States and the EU exchanged tariff offers to reduce and eliminate tariffs on most industrial goods, but opted to leave agricultural tariff issues, which were highly sensitive, until "end-game" negotiations.
Services market access could be significant in potential FTA negotiations, given the high level of U.S.-UK services trade. Regulatory and other barriers to trade in services could be a focal point (see " Regulatory Cooperation and Standard-Setting " section below). Other areas of interest could include issues such as licensing and qualification requirements for professional service providers, as well as rules on the movement of foreign nationals for temporary entry and stay for business travel. Some services issues that were complex in T-TIP may be less so in U.S.-UK FTA negotiations. For instance, "cultural exceptions" were controversial in T-TIP due to the interest of countries like France in protecting its audiovisual sector.
Other market access issues could arise in terms of public procurement. U.S. FTAs include rules to ensure transparent, nondiscriminatory access for U.S. firms to trading partners' public procurement markets in covered sectors at certain thresholds, and vice versa. In the transatlantic context, frictions have included, on the U.S. side, concerns about the transparency of EU public procurement policies, and on the EU side, concerns about U.S. restrictions to certain sensitive sectors, Buy American legislation, and access to U.S. state-level government procurement markets. These issues could also be politically sensitive in U.S.-UK FTA negotiations. President Trump has advocated for a "Buy American" and "Hire American" policy, while the UK released a post-Brexit industrial strategy including a goal of using "strategic government procurement to drive innovation and enable the development of UK supply chains." More restrictive Buy American policies may run afoul of the WTO Government Procurement Agreement (GPA); the United States is a member of the GPA, and the UK also is a GPA member through its membership in the EU (but is not currently a nation-state member of that agreement).
section_title: Trade-Related Rules
paragraphs: U.S. FTAs contain rules and disciplines governing a range of trade-related areas. Potential areas of interest in a bilateral FTA include the following.
Investment . Given high levels of bilateral FDI, investment rules could be a major part of a U.S.-UK FTA. U.S. international agreements on investment typically include market access commitments, investor protections such as nondiscriminatory and minimum standard of treatment, and compensation for direct and, in limited cases, indirect expropriation, as well as enforcement of these obligations through investor-state dispute settlement (ISDS). An open question could be treatment of ISDS, a mechanism for an investor to take a host country to binding arbitration for alleged breaches of obligations. Historically favored by U.S. government and business, ISDS has been a core part of many U.S. and European investment agreements, but triggered public debates on T-TIP because of potential implications for regulatory sovereignty and other issues. An added dynamic is the EU's proposal for an "Investment Court System," which the EU included in recent trade agreements. It differs from ISDS; for example, it has an appellate mechanism while ISDS decisions are final. It is not clear what position the Trump Administration or the UK would take regarding this issue.
Digital trade. Cross-border data flows are key to the U.S.-UK trading relationship, whether for manufacturing operations or financial services firms. Similar to provisions in TPP, a U.S.-UK FTA could address ways to facilitate cross-border data flows for business transactions and reduce barriers to digital trade, such as "forced" localization requirements. Any future UK-EU regulatory relationship may inform the nature of U.S.-UK FTA negotiations on digital trade. Discussions on cross-border flows in a bilateral FTA may not have the same level of sensitivities over privacy issues that constrained the T-TIP negotiations in the wake of disclosures of National Security Agency (NSA) surveillance activity. Such issues were particularly controversial for countries like Germany.
Intellectual property rights (IPR) . Another area of significant interest is rules on IPR protection and enforcement. Both the United States and the UK are major centers of research and development and innovation, view intellectual property as a source of comparative advantage, and are strong proponents of advancing trade-related rules for IP R protection and enforcement. A U.S.-UK FTA could present opportunities for cooperation on IPR issues, such as combating cyber theft of trade secrets and enhancing protections for biologics. A bilateral FTA may not face the same challenges as did T-TIP on IPR issues such as geographical indications (GIs), which protect regional food names. Protection of GIs is a key priority for countries like France and Italy, but less so for the UK (though the UK does have over 60 registered GIs, including for Stilton Cheese and Cornish Pasty). The United States has favored protecting regional food names primarily through trademarks. 
Other issues. A U.S.-UK FTA could also include rules and disciplines in a range of other areas. Some of these are areas that "traditionally" have been a part of U.S. FTAs, such as labor and the environment. The UK's status as a developed economy with strong environmental protections could mitigate concerns of some stakeholders about U.S. outsourcing or reducing environmental standards through an FTA. Other issues for possible discussion have been more recent additions to U.S. FTAs, including rules on state-owned enterprises (SOEs) and commitments to support exports by small- and medium-sized enterprises (SMEs).
section_title: Regulatory Cooperation and Standard-Setting
paragraphs: A U.S.-UK FTA could include commitments on regulatory cooperation and standard-setting, both in terms of horizontal commitments, such as transparency and stakeholder input in regulatory processes, as well as sector-specific commitments. Many of the products in which in the United States and UK trade are in high-value-added but heavily regulated sectors that intersect with consumer safety issues. Sectoral issues of potential interest might include motor vehicle, pharmaceutical, chemical, and food safety regulatory regimes. The United States may view a U.S.-UK FTA as an opportunity to open the UK market to U.S. exports currently constrained by EU restrictions, such as sanitary and phytosanitary (SPS) barriers and technical barriers to trade (TBT). For instance, frictions on the U.S. side have included EU restrictions such as those on chlorine-washed chicken, hormone-raised beef, and genetically engineered food. In general, the UK is more closely aligned with the U.S. approach to regulatory issues than the EU but not necessarily in all areas. For instance, some UK consumers continue to reject genetically engineered foods. 
Regulatory cooperation has been a major sticking point in the overall transatlantic relationship because of differing regulatory approaches. Broadly speaking, the United States prefers risk-based assessments, while the EU favors the "precautionary principle" through preventive decisionmaking in case of risk; both sides view their approaches as science-based. T-TIP negotiations became weighted down by EU public debate over the impact of a U.S.-EU FTA on food safety and other regulatory concerns, though subsequent progress has been made in some areas. For example, in March 2017, the United States and the EU amended a 1998 U.S.-EU Mutual Recognition Agreement to allow for U.S. and EU regulators to rely upon each other's inspections of pharmaceutical manufacturing facilities to avoid duplication of inspections. 
How the United States and the UK approach regulatory cooperation and standard setting within the context of a bilateral FTA will depend in large part on the extent to which the UK reclaims its regulatory authority from the EU during Brexit negotiations, including whether the UK will choose to retain EU regulations or adopt its own national regulations .   T he UK has said that it plans to introduce a "Great Repeal Bill" to remove the European Communities Act 1972 from its statute book and convert the body of existing EU law ( known as "acquis" ) into domestic law where practical and appropriate, after which the UK will decide which elements of the law to keep, amend, or repeal. To the extent that UK regulations align with EU regulations, it may be easier for the UK to continue trading with the EU , but compatibility with U.S. standards could be an issue. I n some areas , UK divergences from the EU in regulatory approaches that minimize inefficiencies could translate into advantage s for UK trade relations with the United States or other countries . 
section_title: Issues for Congress
subsections: section_title: Prospects for a "Successful" U.S.-UK FTA
paragraphs: Prospects for a U.S.-UK FTA depend on a number of factors over which Congress may conduct oversight in the near term. These include how U.S.-UK FTA negotiations could best advance U.S. trade negotiating objectives established in TPA, as well as the barriers to addressing those negotiating objectives. Other issues include timing for when formal negotiations could start legally. As discussed, this depends in large part on the outcome of the UK's Brexit negotiations with the EU. The United States and UK also may have political considerations to take into account in determining when to launch trade negotiations, including in the context of overall trade policy priorities. Capacity to negotiate may be an issue on the UK side. The UK has "outsourced" trade negotiating skills to Brussels for decades as part of the EU's exclusive competence over trade policy, but has sought to rebuild that capacity in recent months. The UK has also indicated interest in negotiating a number of trade agreements, including with countries that have FTAs with the EU and those that do not. The EU has concluded over 50 trade agreements worldwide. Given the many directions UK interest could go and the still growing UK negotiating capacity, an open question is where a U.S.-UK FTA would rank in the priorities. 
Some analysts believe that, once legal and procedural roadblocks to U.S.-UK FTA negotiations are removed, the negotiations would be relatively easy and fast to conclude. One reason is that the UK has been characterized as a liberalizing force within the EU that has shared the United States' traditional support for trade liberalization and a rules-based international trade system. Another reason is that the negotiating dynamics presumably would be less complex because U.S.-UK FTA negotiations would involve two economies, rather than T-TIP's 29 economies (United States and EU-28 member states). Some may counter, however, that the economic impact of a U.S.-UK FTA also would be smaller than T-TIP (see next section).
Some analysts believe that U.S.-UK FTA negotiations would not face the level of substantive and procedural difficulty that beset the T-TIP negotiations. Given these dynamics, some have called for a U.S.-UK FTA to be implemented within 90 days after Brexit—90 days being the amount of time the executive branch must give Congress before it signs a trade agreement under TPA. Others caution that U.S. FTAs typically take much longer to negotiate and that, even among like-minded trading partners, domestic political interests can complicate trade negotiations. 
section_title: Economic and Strategic Impact
paragraphs: Presently, U.S.-UK FTA talks are in an informal, pre-negotiations stage. U.S. FTAs are generally viewed as having widely distributed economic benefits and concentrated economic costs. The economic impact of a specific FTA would depend, in part, on the breadth and depth of FTA commitments. Yet, broad macroeconomic factors generally are considered to play an important role in affecting the U.S. economy as a whole. Given the openness of the U.S. and UK economies, a U.S.-UK FTA may be expected to generate modest economic benefits. Nevertheless, due to the size of the bilateral economic relationship, further trade liberalization could yield significant benefits for particular industries. Regarding the enhanced market access and other benefits that a concluded FTA could bring, some experts caution that no U.S.-UK FTA would replicate the broader EU market access that U.S. affiliates in the UK enjoy by virtue of the UK's membership in the EU and access to the EU Single Market. A potential bilateral FTA could present costs, such as in terms of job losses and other transition costs stemming from increased competition. Such costs, however, could be less than those of other U.S. FTAs, as the United States and the UK are both highly advanced economies. 
As U.S.-UK FTA negotiations advance, Congress likely would examine various studies by the U.S. government (e.g., the U.S. International Trade Commission) and external organizations to assess the expected impact of the agreement on the U.S. economy. It should be kept in mind that economic models are highly sensitive to assumptions. Further, data limitations and other issues—including the fact that a number of variables beyond trade affect economic performance—make it difficult to develop precise estimates of the impact of a particular trade agreement on the economy.
Any economic impact of a U.S.-UK FTA is in the longer term, given that the commencement of U.S.-UK FTA negotiations is at least two years away. Over the short run, Brexit-specific factors may have more economic impact on the United States. These factors include the economic impact of Brexit on the EU and on the UK, the amount of time it takes for the UK withdrawal from the EU, and the final composition of the UK-EU economic relationship—all of which could have implications for U.S. trade and investment with both the UK and the EU. Another aspect of the economic relationship is the impact Brexit will have on financial flows and any secondary impact on the dollar if markets perceive additional uncertainty for a EU economic recovery. 
A U.S.-UK FTA could have broader strategic implications. For instance, a U.S.-UK FTA could play a similar role to what TPP and T-TIP were expected to play in setting globally relevant rules and disciplines to support economic growth and multilateral trade liberalization through the WTO. It also could strengthen the broader U.S.-UK relationship and add a new dimension to the transatlantic trade relationship. In addition, a U.S.-UK FTA could apply pressure on unlocking past stumbling blocks to progress in T-TIP, assuming that both the United States and EU seek to continue negotiations.
section_title: Role in U.S. Trade Policy
paragraphs: A potential U.S.-UK FTA would fit into a new U.S. emphasis on bilateral trade deals under the Trump Administration, which has expressed a clear preference for focusing on bilateral trade deals in lieu of multiparty ones. The Trump Administration has argued that a bilateral approach allows the United States to use its economic strength and focus on U.S. priorities. This represents a shift from the Obama Administration, which made it a priority to negotiate multiparty regional trade deals, such as TPP and T-TIP. Regional negotiations, while more complex, offer the opportunity for mutually beneficial but politically challenging trade-offs to occur across multiple countries. 
Once Brexit procedural roadblocks to U.S.-UK FTA negotiations are overcome, the question arises of when the administration may launch formal negotiations, amid other potential U.S. trade negotiations and other trade policy actions. The Trump Administration says that it aims to focus its future trade efforts on the possibility of renegotiating and reviewing existing FTAs, turning first to NAFTA, and pursuing new bilateral FTAs, including with TPP participants, particularly Japan, and possibly other countries. 
Given the already relatively low levels of trade and investment barriers between the United States and the UK, some question whether it is appropriate for the administration to give priority to negotiating a U.S.-UK FTA. Proponents of a U.S.-UK FTA argue that concluding a bilateral FTA between two economic and political international heavyweights will contribute to future trade liberalization efforts. Others say that, in light of resource constraints and other factors, the United States should pursue FTAs with other countries that present greater barriers to trade. For example, some may argue that the United States would benefit more from resuming T-TIP negotiations or pursuing bilateral deals with countries that were a part of the TPP. 
section_title: Implications for T-TIP and Transatlantic Relations
paragraphs: Since July 2013, the United States and the EU have engaged in T-TIP negotiations to liberalize U.S.-EU trade and investment and set globally relevant rules and disciplines to boost economic growth and support multilateral trade liberalization. The 15 th round, the last under the Obama Administration, occurred in October 2016. By then, the United States and the EU had consolidated texts in a number of areas, but unresolved complex and sensitive issues remained and raised questions over whether political momentum exists to overcome differences. For instance, public opposition to T-TIP runs high in the EU due to concerns over issues such as over food safety regulations, ISDS, and data privacy. Aspects of T-TIP also were controversial among U.S. stakeholders.
T-TIP negotiations are on pause, and the Trump Administration has stated that it is "currently evaluating the status of these negotiations." Should the United States and the EU decide to resume T-TIP negotiations prior to the UK exiting the EU, the European Commission would continue negotiating the T-TIP on behalf of all 28 member states, including the UK. 
Brexit presents uncertainties for T-TIP, despite the Trump Administration's expressions of support for expanding transatlantic trade. Some observers argue that Brexit is a major setback given the UK's historical liberalizing role in the EU on trade issues. Others argue that a U.S.-UK FTA could pressure the EU to reenergize T-TIP, as the EU may be wary of the UK receiving preferential access to the U.S. market without the EU securing similar access. Likewise, if the agreement "in principle" announced in July 2017 on an EU-Japan FTA leads to a ratified FTA between those two economies, it could accelerate U.S. interest in resuming negotiations to ensure U.S. firms' competitiveness in the EU market. Should the United States and the EU decide to resume T-TIP negotiations prior to the UK exiting the EU, the European Commission would continue negotiating the FTA on behalf of all 28 member states, including the UK. After Brexit, the UK could seek to remain in the T-TIP negotiations or could join a potential concluded agreement.
section_title: Outlook
paragraphs: While U.S. and UK interest in negotiating a bilateral FTA is high, including on the part of the Trump Administration and many Members of Congress, the Brexit process means that formal negotiations are at least two years off. In the meantime, the United States and UK can discuss an FTA informally, though such discussions may be constrained by uncertainty surrounding the status of the future UK-EU trade relationship, among other factors. Congress has an important role in examining a potential U.S.-UK trade agreement, U.S. trade negotiating priorities, and other issues through oversight of, and consultations with, the Trump Administration.
