reserve - issuing country has to illustrate a good track record of prudent macroeconomic policy. second, such country must have an open capital account regime supported by deep and liquid financial markets. should these two criteria are satisfied, such currency has a potential to be widely accepted and used in private international transactions. today, it is difficult to find an alternative currency which satisfies these conditions. the loss of economies of scale from using the incumbent currency is another constraint preventing the move away from the current dollar - based system. as such, the dollar continues to dominate the international reserve system both in terms of reserve assets and international trade and financial settlements. 5. given these difficulties, the current international monetary system will prevail but it may be prone to occasional instability as we have experienced in the past. in the meantime, we may still want to consider how to enhance the role of emerging market economies such as brics in the international monetary system. such arrangement is arguably an avenue for these emerging market economies to share the privilege of reserve - issuing countries. it bis central bankers ’ speeches would also be a means of increasing the supply of reserve currencies to serve future demand for reserves along with the growth of the global economy. 6. to facilitate such diversification process, the brics need to also play their part by further opening the capital accounts, allowing currency convertibility and deepening and widening their financial markets. once these conditions are achieved, the inclusion in the sdr basket would increase the demand for brics currencies. 7. it is important to stress that by adding brics to the international system is not a panacea. a key concern is the fact that the triffin dilemma1 could still be problematic. in other words, the provision of global liquidity will continue to largely depend on the macroeconomic conditions of the reserve - issuing countries. as such, there is a great need for policy coordination among them to ensure an orderly supply of global liquidity. in the worst - case scenario, the multi - polar system could be more unstable especially during crisis periods. this is because the reserve currencies are close substitutes among themselves. as such, deterioration in the financial position of one reserve - issuing country could lead to severe capital flight, causing volatility in both exchange rates and asset prices. at this point, it is difficult to foresee if the management of global liquidity in the multi - polar system would be easier or more difficult than the current system. 8

prasarn trairatvorakul : towards a multi - polar currency and reserve system speech by dr prasarn trairatvorakul, governor of the bank of thailand, at the high - level conference on the international monetary system, zurich, 10 may 2011. * * * governor hildebrand, managing director strauss - kahn, distinguished speakers, ladies and gentlemen, 1. i would like to thank the co - hosts, the swiss national bank and the international monetary fund, for inviting me to speak at this high - level conference. so far in this session, we have listened to a number of insightful presentations by well - known speakers. to avoid repeating what has been said, i will try to frame my talk from the perspective of a small emerging market economy. my focus will be on the three problematic issues facing emerging market economies and the current international monetary system, and how we may think of what needs to be done to put our international monetary system on a more sustainable path. 2. let me start with the first issue. as of now, excess global liquidity generated under the current international monetary system is complicating the conduct of macroeconomic policy in many emerging market economies. although the expansion of the global economy has strengthened in the past few quarters, economic cycles and thus monetary policy stance among various regions greatly differ. this has been widely regarded as a key push factor for international capital flows into emerging markets. the additional liquidity infused into these economies occurs at a time when it is necessary to withdraw economic stimulus and normalize or even tighten monetary policy. this is an example of the inconsistency between global liquidity and regional economic cycles. 3. the second issue is the current international monetary system which is not aligning with the changing structure of the global economy. as we all know, one outcome from the current crisis is the growing role of emerging market economies, particularly in asia. this multi - polar economic landscape is something for policymakers to consider whether there is a need to move to a multi - polar currency system. the end goal should be to retain the efficiency of the current system while enhancing its stability going forward. 4. the third issue is, despite the shortcomings of the current international monetary system, the international community has not been able to make a transition to an alternative system. in practice, it is difficult to identify a currency to compete with the us dollar as there are certain criteria to qualify as reserve currency. first, a
