China's increasing financial liberalization over the past two years appears to be paving the way for widespread international use of the renminbi. But major obstacles still stand in the way. Accordingly, we believe that the day is still a long way off when traders need to quote renminbi prices for a significant part of their sales and purchases, especially outside East Asia.

China's cautious approach to financial and monetary policies largely explains this phenomenon. Strict capital controls ensure that its currency is used almost entirely for domestic transactions. Only a small amount of its external trade - mainly with neighbors such as Laos, Myanmar, North Korea, and Vietnam - is denominated in the Chinese currency.

China seems to have stepped up the pace of financial liberalization despite the international financial market volatility of the past two years. In April 2009, the government announced that it would allow renminbi settlement for specific cross-border trading activities in five coastal cities on a pilot basis. As part of this trial, banks in Hong Kong have been allowed to expand their renminbi commercial banking activities to facilitate trade settlement.

The government has also broadened its experiment to build a renminbi financial system in Hong Kong in other ways. The list of institutions allowed to issue renminbi bonds in Hong Kong was expanded to include the mainland subsidiaries of Hong Kong banks. Previously, only mainland banks were allowed this fund-raising option. In September 2009, the Chinese government itself sold renminbi bonds in Hong Kong for the first time.

Recently, the People's Bank of China also signed bilateral currency swap agreements with central banks of Argentina, Belarus, Indonesia, Malaysia, and South Korea. Onshore, China has announced measures to deepen domestic bond market developments, such as easing restrictions on the sale of papers in the interbank market and possibly allowing foreign companies to sell renminbi bonds.

A number of governments that issue internationally used currencies are projecting sharply higher debt levels in the next few years. Consequently, there is now a greater risk that large currency depreciations or high inflation in these countries could erode the value of Chinese foreign currency assets. By reducing the foreign exchange exposure of the Chinese economy through increasing the international use of the renminbi, we believe China could limit such risks for Chinese traders, investors and financial institutions.

Internationalizing the renminbi means, however, that China would have to significantly ease capital controls. With a large pool of renminbi funds abroad, changes in domestic or international market conditions would likely cause strong capital flows. The result could markedly reduce the effectiveness of Chinese monetary or credit policy actions.

Even if China believes that the benefits of currency internationalization outweigh the costs, major hurdles lie ahead. The most important of these is that the renminbi remains non-convertible and subject to strict capital controls. The Chinese market will always be the largest and most liquid market for renminbi funds. If non-residents cannot easily buy and sell the currency and if non-resident financial flows are strictly regulated, the costs and liquidity risks of holding the renminbi would likely deter widespread international use.

China's developing financial markets are largely inaccessible to non-residents, a further impediment to internationalizing the currency. If non-residents are unable to invest these funds in liquid and relatively safe instruments that offer a reasonable rate of return, they are unlikely to hold the currency. Financial derivative markets in China are also insufficiently developed for efficient and cheap hedging against foreign exchange and interest rate risks.

Many people also consider the policy environment in China to be opaque and difficult to predict. International investors and traders are likely to be concerned about abrupt changes that affect their interests for some time to come, despite ongoing policy environment improvements. Until these conditions improve significantly, in our view, large-scale international use of the Chinese currency won't materialize.

The experiences of the euro suggest a challenging time for renminbi internationalization. Despite highly favorable conditions at its inception, the euro has made little headway in rivaling the international importance of the US dollar outside of Europe.

As with other changes in China, we believe that policymakers will gradually make the requisite changes to facilitate cross-border renminbi use. International confidence in the predictability and transparency of Chinese policies will also take time to build. An internationalized renminbi is still far from reality.
