  1. The RMBas an international currency Jeffrey Frankel Harpel Professor of Capital Formation and Growth,Harvard University Club de CEPII, Paris, 12 January, 2011

  2. Questions to be addressed • What is an international currency? • Empirical determinants of international reserve currency status. • The Renminbi • Why should a country care if its currency is used internationally? • 5 reasons why appreciation is in China’s interests. Appendices • China-U.S. currency conflict • Technical addenda

  3. What is an international currency? • Definition: An international currency is used by non-residents. • The prospects for a country’s status as an international currency is not the same as its exchange rate prospects. • Example: 1993-95 • The dollar depreciated strongly, reaching an all-time low against the yen, among much hand-wringing. • And yet its international currency use rose during that period.

  4. Roles of International Currency Central bank holdings of reserves is the most easily quantified, and probably the most important, of the various measures.

  5. People use a given currency when everyone else is using it, not just because of its intrinsic characteristics. English became the international lingua franca not because of its beauty (French), nor its simplicity (Esperanto), nor even the number of native speakers (Chinese). => Network externalities Determination of international currency statusWhat suits a currency for international use?

  6. Determinant Size Depth of financial markets 3. Rate of return Empirical proxy: GDP FX turnover inflation, trend depreciation, or exchange rate variance International reserve currency determinantsfrom the literature on reserve currencies

  7. Determinants of reserve currency standing,continued Network externalities => Tipping captured by: • Inertia lags • Nonlinearity logistic functional form in determinants or dummy for leader GDP Source: Chinn & Frankel (2007)

  8. Historical illustration of the long lag: £ ‘s loss of premier international currency status in 20th century • By 1919, US had passed UK in • output (1872) • trade (1914) • net international creditor position (1914-19) • $ passed £ as #1 reserve currency only with a lag • by 1940-45 • though Eichengreen says 1924.

  11. How does China rank, by determinants of international currency status? 1. Size • Chinese economy famously passed Japan in 2010, to attain 2nd ranking. • Some projections claim it will pass the US soon. • But • What matters here is GDP (and trade) compared at market exchange rates, not PPP-adjusted. • Euroland’s GDP is still substantially bigger than China. • Chinese growth will slow down, • well before it reaches per capita equality with the West.

  12. China’s rank, by determinants of international currency status,cont. 2. Depth of financial markets One the one hand… • China is starting to use RMB in international trade • Foreign central banks can hold RMB since Aug. 2010 • Malaysia’s CB went first, buying RMB bonds for its FX reserves, in Sept. • RMB market is now developing in Hong Kong • Since 2007, RMB 62 b RMB bonds (27 batches) issued off-shore • including by MacDonald’s. • Bank of China HK launched an index Dec. 31, 2010. • In November, RMB deposits reached RMB 280 b.

  13. In Hong Kong banks, yuan-denominated deposits have quadrupled over the last year – but from a low base. “RMB goes viral,” Financial Times, Jan. 4, 2011

  14. Why should a country care?Pros & cons of having one’s currency used internationally. 4 ADVANTAGES TO A COUNTRY OF HAVING ITS CURRENCY USED INTERNATIONALLY. • (1) Convenience for its residents. • (2) Business for its banks & other financial institutions. • (3) Seignorage • narrowly defined as willingness to hold, e.g., the $ as high-powered money (esp. fx reserves held by central banks) or • more broadly as willingness of private investors to hold $-denominated assets: America’s “exorbitant privilege.” • (4) Political power and prestige.

  15. China’s rank, by determinants of international currency status,cont. On the other hand… • RMB bonds and deposits in HK are small as a fraction. • And of course HK$ is itself still firmly tied to US$. • Development of China’s financial market has just begun. • It ranks far behind other major currencies.’ • Still very highly regulated • Domestic system still “financially repressed.” • Cross-border capital flows still subject to heavy controls. • Foreign companies still cannot borrow in China. • Liquidity, breadth, openness… still have a long way to go.

  16. China’s rank, by determinants of international currency status,cont. 3. Rate of return • Inflation in China is again a danger currently. • A financial crisis probably lurks • somewhere down the road. • Nevertheless, it is quite likely that the rate of return to holding RMB over the next ten years will be high. • Indeed that is the reason for the strong portfolio capital inflows since 2004. • Prasad & Wei.

  17. China’s rank, by determinants of international currency status,cont. Inertia suggests that China’s ascent in the currency rankings will be gradual. • The rest of Asia will probably be no keener on a yuan bloc than it was on a yen bloc in the 1980s. • A guess: It will take the RMB a decade to surpass the ₤ & CHF and rival the ¥. • and much longer to rival the €, let alone the $. • Nevertheless, that is the direction it is headed. • And the $ is likely to continue losing share to allthe other international reserve assets in the future.

  20. The global monetary systemmay move from dollar-based to multiple international reserve currencies • The € is still a rival for the $. • The SDR is again part of the system. • Gold in 2009 made a comeback as an international reserve too. • The RMB will join the roster with ¥ & ₤. • = a multiple international reserve asset system. SDR

  21. How can international currency status translate into political power?Precedent: The Suez crisis of 1956 [i] is often recalled as the occasion on which Britain was forced under US pressure to abandon its remaining imperial designs. But recall also the important role played by a simultaneous run on the £ and the American decision not to help the beleaguered currency.

  22. 2 DISADVANTAGES OF HAVING ONE’S CURRENCY USED AS AN INTERNATIONAL CURRENCY. • The possibility of larger fluctuations in the demand for one's money. • The possibility that an increase in demand for the currency would cause it to appreciate sharply, • rendering exporters uncompetitive on world markets. • In the past, the German & Japanese governments were reluctant to see their currencies play larger international roles.

  23. Internationalization of the RMB would likely entail appreciation: • Liberalization of capital controls would allow pent-up demand to show up. • International demand to hold RMB would rise. • China’s fear that appreciation would lose it competitiveness vis-à-vis Asian neighbors would disappear.

  25. Addendum: Five reasons China should let RMB appreciate, in its own interest • Overheating of economy • Reserves are excessive. • It gets harder to sterilize the inflow over time. • Attaining internal and external balance. • To attain both, need 2 policy instruments. • In a large country like China, expenditure-switching policy should be the exchange rate. • Avoiding future crashes. • RMB undervalued, judged by Balassa-Samuelson relationship.

  26. 1. Overheating of economy: • Bottlenecks. Pace of economic growth is outrunning: • raw material supplies, and • labor supply in coastal provinces • Also: • physical infrastructure • environmental capacity • level of sophistication of financial system. • Asset bubbles. • Shanghai stock market bubble in 2007. • Real estate prices now. • Inflation back up to 5.1% last year (to Nov. 2010). • Starting to look like 2007 => price controls • shortages & social unrest. • All of the above was suspended in late 2008, • due to global recession. • But it came back again in 2010.

  27. Attempts at “sterilization,” to insulate domestic economy from the inflows • Sterilization is defined as offsettingof international reserve inflows,so as to prevent them from showing updomestically as excessive money growth & inflation. • For awhile PBoC successfully sterilized… • until 2007-08. • The usual limitations finally showed up: • Prolongation of capital inflows <= self-equilibrating mechanism shut off. • Quasi-fiscal deficit: gap between domestic interest rates & US T bill rate • Failure to sterilize: money supply rising faster than income • Rising inflation (admittedly due not only to rising money supply)

  28. 2. Foreign Exchange Reserves • Excessive: • Though a useful shield against currency crises, • China has enough reserves: $2 ½ trillionby 2010; • & US treasury securities do not pay high returns. • Harder to sterilize the inflow over time.

  29. The Balance of Payments ≡ rate of change of foreign exchange reserves (largely $), rose rapidly in China over past decade, due to all 3 components: trade balance, Foreign Direct Investment, and portfolio inflows Source: HKMA, Half-Yearly Monetary and Financial Stability Report, June 2008

  30. Attempts to sterilize reserve inflow: Successful sterilization in China: 2005-06 High reserve growth =>steadymoney offset by cuts indomestic credit While reserves (NFA) rose rapidly, the growth of the monetary base was kept to the growth of the real economy – even reduced in 2005-06. were remarkably successful in 2005-06.

  31. In 2007-08 China had more trouble sterilizing the reserve inflow • PBoC began to pay higher interest rate domestically, & receive lower interest rate on US T bills => quasi-fiscal deficit. • Inflation became a serious problem. • True, global increases in food & energy priceswere much of the explanation. • But • China’s overly rapid growth itself contributed. • Appreciation is a good way to put immediate downward pressure on local prices of farm & energy commodities. • Price controls are inefficient and ultimately ineffective.

  32. Sterilization faltered in 2007 & 2008 Monetary baseaccelerated Growth of China’smonetary base,& its components Source: HKMA, Half-Yearly Monetary and Financial Stability Report, June 2008

  33. China’s CPI accelerated again in 2010 5.1% in year ended Nov. 2010

  34. 3. Need a flexible exchange rate to attain internal & externalbalance • Internal balance ≡demand neither too low (recession) nor too high (overheating). • External balance ≡ appropriate balance of payments. • General principle: to attain both policy targets, a country needs to use 2 policy instruments. • For a country as large as China, one of those policy instruments should be the exchange rate. • To reduce BoP surplus without causing higher unemployment, China needs both • currency appreciation, and • expansion of domestic demand • gradually replacing foreign demand, • developing neglected sectors: health, education, environment, housing, finance, & services.

  35. 4. Avoiding future crashes Experience of other emerging markets suggests it is better to exit from a peg in good times, when the BoP is strong, than to wait until the currency is under attack. Introducing some flexibility now, even though not ready for free floating.

  36. 5. Longer-run perspective:Balassa-Samuelson relationship • Prices of goods & services in China are low • compared at the nominal exchange rate. • Of course they are a fraction of those in the U.S.: < ¼ . • This is to be expected, explained by the Balassa-Samuelson effect • which says that low-income countries have lower price levels. • As countries’ real income grows, their currencies experience real appreciation: approx. .3% for every 1 % in income per capita. • But China is one of those countries that is cheap or undervalued even taking into account Balassa-Samuelson.

  37. The Balassa-Samuelson Relationship 2005 Source: Arvind Subramanian, April 2010, “New PPP-Based Estimates of Renminbi Undervaluation and Policy Implications,” PB10-08, Peterson Institute for International Economics Undervaluation of RMB in the regression estimated above = 26%. Estimated undervaluation averaging across four such estimates = 31%. Compare to Frankel (2005) estimate for 2000 = 36%.
