The outbreak of the current crisis and its spillover in the world confronted us with the long existing but still unanswered question, i.e., what kind of international reserve currency do we need to secure global financial stability and facilitate world economic growth, which was one of the purposes for establishing the IMF? There were various institutional arrangements in an attempt to find a solution, including the Silver Standard, the Gold Standard, the Gold Exchange Standard and the Bretton Woods system. The above issue, however, as the ongoing financial crisis demonstrates, is far from being solved, and has become even more severe due to the inherent weaknesses of the current international monetary system.

The outbreak of the crisis and its spillover to the entire world reflected the inherent vulnerabilities and systemic risks in the existing international monetary system. The desirable goal of reforming the international monetary system, therefore, is to create an international reserve currency that is disconnected from individual nations and is able to remain stable in the long run, thus removing the inherent deficiencies caused by using credit-based national currencies.

Though the super-sovereign reserve currency has long since been proposed, no substantive progress has been achieved to date. A super-sovereign reserve currency not only eliminates the inherent risks of credit-based sovereign currency, but also makes it possible to manage global liquidity. A super-sovereign reserve currency managed by a global institution could be used to both create and control global liquidity. And when a country's currency is no longer used as the yardstick for global trade and as the benchmark for other currencies, the exchange rate policy of the country would be far more effective in adjusting economic imbalances. This will significantly reduce the risks of a future crisis and enhance crisis management capability.

The reform should be guided by a grand vision and start with specific deliverables. It should be a gradual process that yields win-win results for all.

The reestablishment of a new and widely accepted reserve currency with a stable valuation benchmark may take a long time. The creation of an international currency unit, based on the Keynesian proposal, is a bold initiative that requires extraordinary political vision and courage. In the short run, the international community, particularly the IMF, should at least recognize and face up to the risks resulting from the existing system, conduct regular monitoring and assessment and issue timely early warnings.

Special consideration should be given to give the special drawing rights (SDR) a greater role. The SDR has the features and potential to act as a super-sovereign reserve currency. Moreover, an increase in SDR allocation would help the Fund address its resources problem and the difficulties in the voice and representation reform. Therefore, efforts should be made to push forward a SDR allocation. This will require political cooperation among member countries. Specifically, the Fourth Amendment to the Articles of Agreement and relevant resolution on SDR allocation proposed in 1997 should be approved as soon as possible so that members who joined the Fund after 1981 can also share the benefits of the SDR. On the basis of this, considerations could be given to further increase SDR allocation.

The scope of using SDR should be broadened, so as to enable it to fully satisfy the member countries' demand for a reserve currency. Measures may include the following:

Set up a settlement system between the SDR and other currencies. Therefore, the SDR, which is now only used between governments and international institutions, could become a widely accepted means of payment in international trade and financial transactions.

Actively promote the use of the SDR in international trade, commodities pricing, investment and corporate book-keeping. This will help enhance the role of the SDR, and will effectively reduce the fluctuation of prices of assets denominated in national currencies and related risks.

Create financial assets denominated in the SDR to increase its appeal. The introduction of SDR-denominated securities, which is being studied by the IMF, will be a good start.

Further improve the valuation and allocation of the SDR. The basket of currencies forming the basis for SDR valuation should be expanded to include currencies of all major economies, and the GDP may also be included as a weight. The allocation of the SDR can be shifted from a purely calculation-based system to one backed by real assets, such as a reserve pool, to further boost market confidence in its value.

Entrusting part of the member countries' reserve to the centralized management of the IMF will not only enhance the international community's ability to address the crisis and maintain the stability of the international monetary and financial system, but also significantly strengthen the role of the SDR.

Compared with separate management of reserves by individual countries, the centralized management of part of the global reserve by a trustworthy international institution with a reasonable return to encourage participation will be more effective in deterring speculation and stabilizing financial markets. The participating countries can also save some reserve for domestic development and economic growth. With its universal membership, its unique mandate of maintaining monetary and financial stability, and as an international "supervisor" on the macroeconomic policies of its member countries, the IMF, equipped with its expertise, is endowed with a natural advantage to act as the manager of its member countries' reserves.

The centralized management of its member countries' reserves by the Fund will be an effective measure to promote a greater role of the SDR as a reserve currency. To achieve this, the IMF can set up an open-ended SDR-denominated fund based on the market practice, allowing subscription and redemption in the existing reserve currencies by various investors as desired. This arrangement will not only promote the development of SDR-denominated assets, but also partially make management of liquidity in the form of the existing reserve currencies possible. It can even lay a foundation for increasing SDR allocation to gradually replace existing reserve currencies with the SDR.
