Since their creation a decade ago, cryptocurrencies have become more prominent in the global economy. Cryptocurrencies are digital representations of value that have no status as legal tender and are administer ed using distributed ledger technology, running on a network of independent, peer-to-peer computers. Bitcoin is the most common and well-known cryptocurrency, but according to one estimate, about 2,100 cryptocurrencies are currently in circulation. Some analysts believe that cryptocurrencies could revolutionize the financial and banking industries, increasing the speed and reducing the cost of transactions. Others believe that cryptocurrencies, which do not have status as legal tender, are a scam and a financial bubble that has burst, as evidenced by the approximately 85% drop in value of cryptocurrencies over the course of 2018. Governments around the world are taking different approaches to cryptocurrencies. Some governments are actively promoting digital currencies in their jurisdictions, while others are banning them outright. Others still are seeking a middle path, allowing cryptocurrency transactions, but regulating the industry to minimize the risks. The interest and debate surrounding cryptocurrencies has led some central banks to examine whether the technology underpinning cryptocurrencies could be leveraged to create digital versions of state-created currencies, which would have legal status in their jurisdiction of issue. A major policy question is whether state-issued digital currencies could draw on the benefits of cryptocurrencies while minimizing the risks, but there are varying views on the need for or desirability of digital fiat currencies. The policy questions posed by digital currencies, as well as variation in government responses, have also become a focus for several international organizations and forums. In November 2018, the U.S. Department of the Treasury announced it is developing a report on cryptocurrency regulation, including a legislative framework for the 116 th Congress to consider in 2019. As Congress considers issues related to digital currencies, including whether to regulate further the cryptocurrency industry, the approaches taken by other governments and international bodies may be of interest. This report is part of a suite of CRS products on digital currencies and the underlying technology, distributed ledger technology and blockchain (see textbox below). Money is the set of assets in an economy that consumers, businesses, and governments regularly use to buy goods and services from others. It has three functions in the economy: 1) a medium of exchange (an item that buyers give to sellers when they want to purchase goods and services); 2) a unit of account (the yardstick people use to post prices and record debts); and 3) a store of value (an item that people can use to transfer purchasing power from the present to the future). Traditionally, money has taken two major forms ( Figure 1 ). Commodity money is made of materials that have intrinsic value, like gold and silver coins. Fiat money has no intrinsic value, but serves as money by government decree. Before World War I, most countries were on the gold standard, using gold coins or paper money convertible to gold on demand. Today, most countries, including the United States and other major economies, use fiat money as national currencies. More recently, technological developments have led to the creation of virtual currencies , digital representations of value that can be digitally traded (without any physical banknotes or coins) and strive to function as a medium of exchange, unit of account, and store of value. However, unlike a fiat currency, virtual currencies generally do not have legal tender status in any jurisdiction; they have value only by agreement within the community of users of the virtual currency. There are different types of virtual currencies. Convertible virtual currencies can be exchanged back-and-forth with fiat (real) currencies, while non convertible virtual currencies are used in restricted online domains (such as multiplayer online gaming) and are not converted into fiat currencies. There are a number of exchanges that have been established to facilitate the conversion of virtual currencies to other assets, such as conventional fiat money or different virtual currencies. Additionally, some virtual currencies are run by a centralized administrator that issues currency and maintains a central payment ledger. Other virtual currencies are decentralized , for which transactions are recorded on a distributed ledger, which is maintained by many independent, peer-to-peer computers. They rely on encryption techniques to control the creation of monetary units and to verify the transfer of funds. Users are given some level of anonymity or pseudonymity, and the system does not rely on government agencies (central banks) or financial institutions, which are generally embedded in the creation and transfer of fiat money. Convertible, decentralized virtual currencies are often referred to as cryptocurrencies . Bitcoin was the first and continues to be the most widely used cryptocurrency, but a number of competitors have emerged. According to one estimate, there are about 2,100 cryptocurrencies currently in circulation, with a total market capitalization of $121.1 billion as of November 25, 2018. As cryptocurrencies have proliferated, they have taken on more forms. Some virtual currencies, such as Ripple, are arguably centralized currencies, but nonetheless are frequently referred to under the general umbrella term of cryptocurrencies. "Cryptocurrency" is sometimes used broadly for any digital currency not issued by a sovereign government. One process by which new cryptocurrency coins or tokens are issued is called initial coin offerings (ICOs) . Cryptocurrency currency transactions are validated by a process known as mining ; successful miners are rewarded for their efforts through new cryptocurrency tokens. A number of companies have also developed to facilitate the use of cryptocurrencies. For example, exchanges are platforms that allow customers to trade cryptocurrencies for other cryptocurrencies and/or fiat currencies. Wallets are applications or interfaces that can be downloaded onto a device to make transacting in cryptocurrencies more user friendly. Some central banks are considering or are actively exploring using distributed ledger technology to create digital representations of fiat currencies, or digital fiat currencies . Thus far, Venezuela is the only country that has launched a digital fiat currency, but several other central banks are in the process of doing so or undertaking research efforts to consider the option. Digital currency is a broad term that refers to virtual (nonfiat) currency and digital fiat currency. In the 10 years since Bitcoin was first issued, the size and scope of the global cryptocurrency market initially increased dramatically. After peaking at over $800 billion in January 2018, the cryptocurrency market fell by about 85% in 2018 to $121.1 billion on November 25, 2018 ( Figure 2 ). Bitcoin was the first and continues to be the most widely used cryptocurrency, but about 2,100 competitors have emerged. Bitcoin has the largest market share, accounting for about half of the total market capitalization. The five largest cryptocurrencies account for almost 80% of the total virtual currency market capitalization, and include Bitcoin ($65.5 billion), Ripple ($14.0 billion), Ethereum ($11.2 billion), Bitcoin Cash ($3.0 billion, a 2017 offshoot of Bitcoin); and EOS ($2.9 billion) ( Figure 2 ). Cryptocurrencies generate a lot of debate. Some argue that the development and spread of virtual currencies have the potential to revolutionize the financial and banking industries. Virtual currencies could increase payment efficiency, reduce transaction costs of payments and fund transfers, increase participation in the financial system, and facilitate transactions. Others are far more skeptical. The value of virtual currencies is highly volatile, virtual currencies and the exchanges on which they are traded face an uneven regulatory framework compared to banks, creating concerns for consumer protections and anti-money laundering efforts, and virtual currencies require sizeable energy resources for the associated computations. Cryptocurrencies are still a relatively new phenomenon, and the market size is relatively small compared to other global financial markets. Whereas the cryptocurrency market was valued at $121.1 billion on November 25, 2018, the global stock market is valued around $80 trillion and the global bond market is valued around $250 trillion ( Figure 2 ). A 2016 survey estimated that trading in foreign exchange markets (with traditional fiat currencies) averages $5.1 trillion per day. Global net inflows of foreign direct investment are around $2.0 trillion annually. Cryptocurrencies span borders and are international in nature, but governments around the world have responded differently to the proliferation of cryptocurrencies. Governments have applied different nomenclatures and definitions, and tackled different legal and policy questions, including their tax treatment, their anti-money laundering/countering the financing of terrorism (AML/CFT) implications, their reporting requirements, and the conduct rules for financial institutions dealing with them. Three government responses to cryptocurrencies are seen: 1) encouraging the use and development of cryptocurrencies within the jurisdiction; 2) banning or restricting the use of cryptocurrencies within the jurisdiction; and 3) regulating the use of cryptocurrencies to minimize potential risks while encouraging financial innovation. Since cryptocurrencies are still relatively new, government approaches in some cases are still evolving. Some governments are actively seeking to become cryptocurrency hubs by attracting and developing cryptocurrency industries in their countries. These governments generally view cryptocurrency as an important financial innovation that can create jobs and generate economic activity. They have created frameworks tailored to, and designed to attract, a range of businesses and activities in the cryptocurrency industry, including cryptocurrency exchanges and ICOs. For example, Malta is creating a "crypto-friendly" framework that covers cryptocurrency brokerages, exchanges, asset managers, and traders, which aims to provide the "necessary legal certainty to allow this industry to flourish." The framework entails a range of discussion papers and legislation, passed in July 2018, and the creation of a "National Blockchain Strategy Taskforce" to advise the government on a framework for cryptocurrencies and other distributed ledger technology applications. Malta's favorable tax rate for international companies is also attracting businesses associated with the cryptocurrency industry. Nicknamed "Blockchain Island," Malta has attracted two prominent crypto exchanges (Binance and OKEx), among other companies working in the cryptocurrency industry. Similarly, Singapore is striving to become a cryptocurrency hub in Asia, with analysts describing its regulators as well-informed and transparent about blockchain and cryptocurrency, compared to regulatory uncertainties in other jurisdictions. The government has used various policies to promote the use of cryptocurrencies, including a "token day," when some retailers accept various cryptocurrencies as payment in an effort to normalize their use. Singapore has attracted 56 initial coin offerings in the first five months of 2018 raising over $1 billion, compared to 35 ICOs raising $641 million during all of 2017. Switzerl and is also seeking to create a cryptocurrency industry, or "Crypto Valley," a cluster of companies associated with the cryptocurrency akin to the cluster of technology companies in Silicon Valley. "Crypto Valley" is located in Zug, a small town outside of Zurich. The jurisdiction has tried to attract cryptocurrency companies and exchanges through the early adoption of regulations designed to provide regulatory certainty; these regulations are also generally viewed as favorable to attracting cryptocurrency activities. As with Malta, multinationals are attracted to Zug's low tax rates. Companies that created and promote Ethereum, the second largest cryptocurrency by value, are located in Zug, and as many as 200-300 cryptocurrency entities have opened there in recent years. Government agencies in Zug also accept cryptocurrencies as a means of payment. However, following the publishing of ICO guidelines in February 2018, many cryptocurrency businesses presumably feeling the regulations too restrictive left Switzerland for rivals such as Liechtenstein, Gibraltar, and the British Virgin Islands. Companies in the cryptocurrency industry have approached the Swiss central bank and regulators in efforts to make Swiss banks more accessible to cryptocurrency ventures. Some governments have banned the use of cryptocurrencies or specific activities associated with cryptocurrencies. These governments generally view the risks of cryptocurrencies, including undermining financial stability, lack of investor and consumer protections, and the potential for illicit transactions, as more significant than the possible benefits. For example, the Chinese government has put broad restrictions on the use of cryptocurrencies and related activities. In 2013, it restricted Chinese banks from using cryptocurrencies as currency, citing concerns about money laundering and a threat to financial stability. In 2017, the Chinese government banned ICOs and restricted cryptocurrency exchanges operating in China, as part of broader efforts against financial risks following a rapid run-up in corporate debt and a proliferation of new, risky investment products. In 2018, Chinese authorities in an eastern district of Beijing directed stores, hotels, and offices not to host any cryptocurrency-related speeches, events, or activities, and blocked a number of public accounts involving ICOs on the popular messaging app WeChat. South Korea has also banned some cryptocurrency activities. A week following China's ban on ICOs, South Korean financial regulators banned ICOs as well, citing concerns about the increasing risk of financial scams. South Korea has not, however, gone as far as China in restricting cryptocurrency activities, however; in January 2018, South Korea's finance minister said the government has no plans to shut down cryptocurrency trading on exchanges. India has also imposed tight restrictions on cryptocurrencies, and the Secretary of Economic Affairs recommended a formal ban on cryptocurrencies. In April 2018, India's central bank, the Reserve Bank of India, banned banks, financial institutions, and other regulated institutions from providing any services related to virtual currencies, giving the institutions three months to exit operations. The directive was upheld by India's Supreme Court in July 2018, during which the central bank argued that cryptocurrencies cannot be treated as currency under India's existing law that mandates coins be made of metal or exist in physical form and be stamped by the government. In October 2018, a committee chaired by the Secretary of Economic Affairs recommended devising a legal framework to ban the use of cryptocurrencies in India. In addition, Bangladesh and Kyrgyzstan have banned cryptocurrencies; Bolivia has banned any currency not issued by a government, including cryptocurrencies; Egypt has prohibited trading in cryptocurrencies; Indonesia has banned cryptocurrency transactions; Lebanon has banned financial institutions from dealing with virtual currencies; Taiwan has banned banks from transacting in cryptocurrencies; and Vietnam has banned the use of virtual currencies for payment. Some governments are seeking to regulate cryptocurrencies. These governments stop short of banning cryptocurrencies but are not actively seeking to become cryptocurrency hubs. In general, they appear to seek balance between encouraging financial innovation and managing the risks posed by cryptocurrencies, while providing greater clarity surrounding the emergence of cryptocurrencies. Regulations are a mix of applying existing regulations to cryptocurrencies and developing new regulations specifically targeting cryptocurrencies. Although governments vary in the types of cryptocurrency activities they have sought to regulate, regulations have commonly focused on, for example, cryptocurrency exchanges, the taxation of cryptocurrencies, and the application of security laws to ICOs. There is wide variation among countries in how these regulations are applied. For example, in terms of the exchanges, countries vary in whether they require the exchanges to register with the government, apply anti-money laundering and counter terrorist financing regulations, and meet minimum capital and cybersecurity requirements, among other factors. In terms of the tax treatment of cryptocurrencies, governments vary in whether they are taxing cryptocurrencies, and if so, whether they are applying, for example, value-added-tax, capital gains tax, or property tax to cryptocurrencies. Governments also vary in whether they apply securities laws to ICOs, and if so, which characteristics make an ICO subject to securities laws. More detailed examples are in the text box below ("Regulations Applied to Cryptocurrency Transactions: Examples"). Despite the differences in regulatory approaches, one survey of cryptocurrency regulations around the world finds one of the most common activities across countries is government-issued warnings about the pitfalls of investing in cryptocurrency markets. The warnings are mostly issued by central banks, and are largely designed to educate citizens about the difference between fiat currencies and cryptocurrencies. The warnings caution that citizens invest in cryptocurrencies do so at their own personal risk and there is no legal recourse available in the event of loss. Some central banks are experimenting with or exploring the creation of digital fiat currencies, or digital representations of fiat currency that also rely on distributed ledger technology. Digital fiat currencies have also been called "central bank cryptocurrencies" and "central bank digital currencies." The administration of digital fiat currencies would set them apart from existing electronic central bank payments. Distributed ledger technology would allow digital fiat currencies to be exchanged directly between the payer and payee without the need for a central intermediary. In contrast, other existing forms of electronic central bank money, such as reserves, are exchanged across accounts at the central bank. Digital fiat currencies could take different forms. For example, a digital fiat currency could be widely available for retail transactions (involving individuals or small businesses) or restricted to wholesale transactions (involving just banks and other financial institutions). Additionally, design choices could entail the degree of anonymity, security, transaction limits, operational availability, and interest earned. Digital fiat currencies could improve efficiency and reduce settlement costs, some say, and if focused on retail transactions, grant greater public access to accounts at the central bank. In addition, some observers have argued that digital fiat currencies could allow central banks to more directly transmit monetary policy to their economies, and perhaps allow them to escape the zero lower bound constraints and transmit negative rates. However, some analysts are concerned that digital currencies would increase the size, role, and power of central banks in the economy in an undesirable way. It could give the central bank a significant role in the allocation of credit in the economy, and put a central bank in competition with private banks, which are generally regulated by the central bank. The availability of digital currencies backed by the central bank could also increase the likelihood and severity of runs on private banks during financial crises. There are also concerns about operational risks arising from disruptions and cyberattacks. Governments have varying views on digital fiat currencies. As yet, one country, Venezuela, which is mired in a serious economic crisis, has issued a digital fiat currency, and there are serious questions about the new currency's success. A few small countries are in the process of launching digital fiat currencies. Some countries, including China and Sweden, are researching the costs and benefits of these currencies, and Iran and Russia are considering them as a way to evade U.S. sanctions. Over time, they may decide to ultimately adopt or rule out digital currencies. Many central banks in major economies, including in the United States and the Eurozone, have ruled out issuing a digital fiat currency at this time. Venezuela is the only government to date that has launched a digital fiat currency. Venezuela is in the throes of a deep economic and humanitarian crisis under the authoritarian rule of President Nicolas Maduro. The economy has contracted by more than a third since 2014, is grappling with hyperinflation and is facing critical shortages in food and medicine; millions of Venezuelans have fled to neighboring countries. In December 2017, Maduro announced plans to launch a new digital fiat currency, the "petro," backed by oil reserves and administered using blockchain technology. Maduro hoped that creating and selling a new digital currency, if successful, could provide the cash-strapped government with a fresh infusion of funds. Maduro also stressed that the petro would help Venezuela "advance in issues of monetary sovereignty, to make financial transactions and overcome the financial blockade," an apparent reference to U.S. sanctions that restrict Venezuela's access to U.S. financial markets. There were a number of questions about how such a currency would operate, including how it would be administered and how the oil guarantee would work. The government launched the petro in February 2018 through a private presale that went through mid-March. The government claims it raised $3.3 billion, but the amount raised has never been confirmed by an independent audit. Venezuelans are prohibited from buying petros with the local currency, at the time the bolivar , but the government claimed to draw investors from Turkey, Qatar, and Europe. Many analysts are skeptical about the viability of the petro, which sold at a deep discount from the face value. In March 2018, the Trump Administration through executive order banned U.S. individuals and entities from purchasing or transacting in any digital currency issued by the Venezuelan government. Some analysts have called the petro a "scam," saying there is a lack of key technical information about how the currency is actually backed by oil, as well as concerns that the government, with a long history of economic mismanagement, will be unable to manage complex blockchain technology. In August 2018, the Venezuelan government devalued the bolivar by about 95%, renamed the currency the "sovereign bolivar ," and pegged it to the petro. However, there are few signs of the petro being circulated within Venezuela or sold on any major cryptocurrency exchange. A few other countries are in the process of developing or launching their own digital fiat currencies The Eastern Caribbean Central Bank (ECCB), the monetary authority for eight island economies (Anguilla, Antigua and Barbuda, Dominica, Grenada, Montserrat, Saint Kitts and Nevis, Saint Lucia, and Saint Vincent and the Grenadines), has signed a memorandum of understanding in March 2018 with a Barbados-based financial technology company to launch a pilot program that will enable it to issue a digital currency. The Marshall Islands plans to issue a decentralized digital currency as a second legal tender in addition to the U.S. dollar, enacting the necessary legislation in February 2018. A foreign private company--an Israel-based start-up which, according to the IMF, "limited financial sector experience"--would be in charge of the issuance. In Lithuania , the central bank announced plans in March 2018 to issue a digital collector coin using blockchain or similar technology. Some central banks are in the process of researching the possible adoption of a digital currency. The Swedish central bank, Riksbank, is investigating whether its currency, the Swedish kronor, should be made available in electronic form, the so-called "e-krona." In China , the central bank (the People's Bank of China) is researching the creation of a state-backed digital currency. It has opened an Institute of Digital Money and designed a prototype. Iran and Russia are considering issuing digital fiat currencies as a way to avoid U.S. sanctions. Iran is developing plans for a digital fiat currency, but it is unclear when it would launch or how the currency would operate in practice. There is some speculation that Russia could launch a digital fiat currency, the "CryptoRuble," in the middle of 2019, but no formal announcement to date has been made. Several central banks in advanced economies, including the U.S. Federal Reserve , the European Central Bank (ECB), the Bank of England , the Reserve Bank of Australia , the Bank of Israel, and the Reserve Bank of New Zealand , have argued against the benefits of digital fiat currencies and/or announced that they do not intend to adopt a digital fiat currency at this time. To varying degrees, they have questioned the need for digital fiat currencies and cautioned that digital fiat currencies could undermine financial stability. The emergence of digital currencies has captured attention outside of national-level governments. Many international organizations and forums are examining the potential implications of digital currencies and, in some cases, are starting to make policy recommendations. They have examined a range of issues, including the utility of digital currencies for improving the international payments systems; the possible threats digital currencies may or may not pose to international financial stability; the divergence of national-level cryptocurrency regulations and whether international regulatory coordination is desirable; how cryptocurrencies should be treated in bank prudential regulation; and how to adapt international recommendations to combat money laundering and terrorist financing to cryptocurrencies. Below is an overview of major assessments and recommendations from different intergovernmental forums and organizations on digital currencies; a more thorough discussion is provided in the Appendix ( Table A-1 ). The G-7 and G-20 finance ministers and central bank governors have discussed cryptocurrency and its implications for global financial stability; they have expressed a desire to coordinate national-level regulations of cryptocurrencies, similar to their work coordinating financial regulatory policies following the global financial crisis of 2008-2009. The Financial Stability Board (FSB) , which promotes international financial stability by coordinating national financial authorities and international standard-setting bodies, created a framework to monitor the financial stability implications of developments in cryptocurrency markets. The FSB found that cryptocurrencies do not currently pose a risk to global financial stability. The FSB cautions that cryptocurrencies could pose risks in the future but the risks are difficult to assess and monitor due to information gaps about the market. The International Monetary Fund (IMF) , an international organization tasked with promoting international monetary stability, has weighed the pros and cons of cryptocurrencies. IMF Managing Director Christine Lagarde has said that international regulation and supervision of cryptocurrencies is "inevitable." The IMF has also discouraged at least one country (the Marshall Islands) from adopting a digital fiat currency, and released a staff discussion paper conceptually evaluating the creation of digital fiat currencies. The Basel Committee on Banking Supervision (BCBS) , the primary global standard setter for the prudential regulation of banks and a forum for regular cooperation on banking supervisory matters, is assessing banks' direct and indirect exposure to cryptocurrencies. It is also considering whether to formally clarify the prudential treatment of cryptocurrencies across the set of risk categories. The Financial Action Task Force (FATF) , which sets standards and promotes effective implementation of legal, regulatory, and operational measures for combating money laundering and terrorist financing, has adapted its recommendations to combat money laundering and terrorist financing to clarify how they apply in the case of financial activities involving virtual currencies. The International Organization of Securities Commissions (IOSCO ) , an association of organizations that regulate the world's securities and futures markets, has discussed the investor protection concerns posed by ICOs. The Bank for International Settlements (BIS) , which fosters monetary and financial stability through discussion and collaboration among central banks, has assessed the utility and risks of digital fiat currencies. The World Bank , a multilateral development bank that promotes economic development around the world, has been critical of cryptocurrencies but used the underlying technology to issue the world's first bond created and managed using blockchain technology. After 10 years, the relevance, utility, and implications of digital currencies powered by distributed ledger technology are still evolving. For cryptocurrencies, the market is worth roughly 15% of its peak at the start of 2018, but the number of cryptocurrencies continues to grow. Meanwhile, governments are taking different approaches to cryptocurrencies. The resulting patchwork of national-level cryptocurrency regulation is being assessed by international organizations and forums; these groups are considering whether greater coordination is needed. They are also considering many policy issues raised by cryptocurrencies, ranging from efforts to combat money laundering to updating bank prudential standards to financing World Bank development projects. Some central banks are also considering, or are in the process of, launching digital fiat currencies, while others have determined that at present digital fiat currencies are either unnecessary or undesirable. The changing and developing international landscape for digital currencies raises a number of potential oversight issues and questions for Congress. These include the following: The Department of the Treasury announced it is developing a report on cryptocurrency regulation, including a legislative framework for Congress to consider in 2019. How do U.S. current regulations and the Treasury's proposed framework, when released, compare to other countries' regulations? What lessons might be gleaned from other countries that could inform U.S. regulations of the cryptocurrency market? Some governments are actively recruiting cryptocurrency companies and developing cryptocurrency industries. Should the United States follow suit, or risk losing market share in the industry? Alternatively, some governments are tightly restricting, or even banning, cryptocurrency activities to protect consumers. In the United States, do consumers have adequate protections in terms of cryptocurrencies? In April 2009, the G-20 leaders agreed that "major failures in the financial sector and in financial regulation and supervision were fundamental causes of the [global financial] crisis." The G-20 leaders then launched a major multi-year effort to undertake and coordinate financial sector reforms. Ten years after the crisis, cryptocurrency has emerged as a new financial market, and national governments are taking dramatically different regulatory approaches. Does the experience of the global financial crisis suggest that there should there be more international coordination on digital currency regulations? Or does variation in regulatory approaches allow for desirable financial innovation and competition in a growing industry? Has the Federal Reserve adequately assessed the potential benefits and costs of developing a digital U.S. dollar relying on distributed ledger technology? How does the U.S. position on this issue compare to other countries' calculations? If other countries proceed with digital fiat currencies and the United States does not, would this affect the status of the U.S. dollar as a reserve currency? Or does the continuing importance of the U.S. dollar give the United States a leadership role in shaping the international payment systems, including the extent to which distributed ledger technology is adopted? Many international organizations and forums are working on various aspects of digital currencies. Is there, or should there be, a leading international body on digital currency, and if so, which one? How are international bodies dividing up analysis of digital currencies, and how are they coordinating their work? Is there duplication of efforts, or gaps, in international bodies' analysis of digital currencies? What digital currency policies are being advocated by the Trump Administration at various international organizations? How much sway does the United States have in shaping these discussions? How do international recommendations and standards fit with U.S. regulations?

Summary:
Since Bitcoin was introduced a decade ago, about 2,100 cryptocurrencies have been developed. Cryptocurrencies are digital representations of value that have no status as legal tender and are administered using distributed ledger technology, running on a network of independent, peer-to-peer computers. Cryptocurrencies are controversial. Some think they will revolutionize the international payments system for the better; others are skeptical of the business model, calling it a scam. The interest and debate surrounding cryptocurrencies has led some central banks to examine whether the technology underpinning cryptocurrencies could be used to create digital versions of fiat currencies, which would have legal status in their jurisdiction of issue. Governments around the world are taking different approaches to cryptocurrencies and digital fiat currencies, an area of increasing focus for international organizations and forums underpinning the global economy. As Congress considers issues related to digital currencies, including whether to regulate further the cryptocurrency industry, the approaches taken by other governments and international bodies may be of interest. National Approaches to Cryptocurrencies Cryptocurrencies span borders and are international in nature, but governments around the world have responded differently to the proliferation of cryptocurrencies. Three types of responses have generally taken shape. First, some governments, such as Malta, Singapore, and Switzerland, are active cryptocurrency hubs; they have been attracting and developing cryptocurrency industries in their countries. Second, some governments, such as China, India, and South Korea, have banned the use of cryptocurrencies or specific activities associated with cryptocurrencies. Third, some governments, including many European countries and the United States, are seeking balance between financial innovation and risk-management through regulation of cryptocurrencies. National Approaches to Digital Fiat Currencies To date, one country, Venezuela, which is mired in a serious economic crisis, has issued a digital fiat currency, and there are serious questions about the new currency's success and operational viability. A few small countries are in the process of launching digital fiat currencies. Some countries, including China and Sweden, are researching the costs and benefits of these currencies, and Iran and Russia are considering them as a way to evade U.S. sanctions. Many central banks in major economies, including in the United States and the Eurozone, have argued against issuing a digital fiat currency at this time. International Bodies' Engagement on Digital Currencies Many international organizations and forums are examining the implications of cryptocurrencies and, in some cases, are starting to make policy recommendations. They have examined a range of issues, including the utility of digital currencies for improving the international payments systems, the possible threats digital currencies may or may not pose to international financial stability, the divergence of national-level cryptocurrency regulations and whether international regulatory coordination is desirable, how cryptocurrencies should be treated in bank prudential regulation, and how to adapt international recommendations to combat money laundering and terrorist financing in light of cryptocurrencies. Possible Questions for Congress In November 2018, the Department of the Treasury announced it is developing a report on cryptocurrency regulation, including a legislative framework for Congress to consider in 2019. How do U.S. current regulations, and the proposed regulations when they are released, compare to other countries' regulations? Some governments are actively developing cryptocurrency industries. Should the United States follow suit, or risk losing market share in the industry? Alternatively, some governments are tightly restricting, or even banning, cryptocurrency activities to protect consumers. In the United States, do consumers have adequate protections in terms of cryptocurrencies? Has the Federal Reserve adequately assessed the potential benefits and costs of developing a digital U.S. dollar relying on distributed ledger technology? How does the U.S. position on digital fiat currencies compare to other countries' calculations? What are the potential future impacts on the role of the dollar as a reserve currency? What types of digital currency policies is the Trump Administration advocating at various international organizations? How do international recommendations and standards fit with U.S. regulations?
