“Global imbalances are back, with issues that worried us before the crisis - large and volatile capital flows, exchange rate pressures, rapidly growing excess reserves - on the front burner once again,” Strauss-Kahn said. “Left unresolved, these problems could even sow the seeds of the next crisis.”
“When we worry about the deficiencies of the international monetary system, we are mostly worrying about volatility,” he added. There is “a sense that money sometimes flows around the globe in too-volatile a fashion and that countries need a more stable, more predictable external environment in order to prosper”, he said.
He suggested adding emerging market countries' currencies, such as the yuan, to a basket of currencies that the IMF administers could add stability to the global system.
China, which holds much of its $2.85 trillion mountain of reserves in US Treasury bonds, has repeatedly expressed unease about the value of the dollar, while American politicians have complained that Beijing gains an unfair advantage by keeping its own currency cheap.
Strauss-Kahn saw a greater role for the IMF's Special Drawing Rights, which is currently composed of the dollar, sterling, euro and yen, over time but said it will take a great deal of international cooperation to make that work.
"Using the SDR to price global trade and denominate financial assets would provide a buffer from exchange rate volatility," Strauss-Kahn said, while "issuing SDR-denominated bonds could create a potentially new class of reserve assets".
