(MENAFN - AFP) Monetary easing in the developed world could cause overheating and asset bubbles in emerging economies, the International Monetary Fund's managing director said in Tokyo on Sunday.
"Accommodative monetary policies... could strain the capacity of those economies to absorb the potentially large flows and could lead to overheating asset price bubbles," Christine Lagarde told the close of the IMF and World Bank's annual meeting.
Critics in emerging nations have argued that easing measures, particularly in the United States, have driven down the value of the dollar and sparked huge capital flows to spill across their borders, raising the risk of overheating and driving up national currencies.
On Friday Brazilian Finance Minister Guido Mantega warned that his country would take "whatever measures it deems necessary" to fight the problem.
"Emerging markets can't passively endure large and volatile capital flows and currency fluctuations caused by rich countries' policies," Mantega said in Tokyo.
"Advanced countries cannot count on exporting their way out of the crisis at the expense of emerging-market economies."
Mantega added: "Currency wars will only compound the world's economic difficulties."
However US Federal Reserve chief Ben Bernanke on Sunday rejected claims that central bank easing in rich countries was to blame for the huge waves of capital flowing into emerging economies.
"The linkage between advanced-economy monetary policies and international capital flows is looser than is sometimes asserted," he said in a statement.
The top US central banker added that the "beneficial effects" of the Fed's policies in propping up the US economy -- the world's biggest and a key developing-world export market -- should be given "appropriate weight".
The Fed has maintained an ultra-low interest rate policy for several years, pumping about 2.3 trillion into the US economy to stimulate growth. Last month, the central bank decided to inject 40 billion a month to help an economy beset by stubbornly high unemployment.
Lagarde on Sunday appeared to be playing a balancing act on the effect of easing policies by central banks in Europe, Japan and the United States.
"We have seen several bold initiatives by major central banks certainly that the IMF highly praises and values as major contributing factors to stability," she said.
"These are big policy actions in the right direction. Indeed central bankers must play a significant role in pulling the global economy out of the current malaise."
But Lagarde acknowledged "there are diverging views within and across countries about important issues including the management of capital flows.
"Disagreement might be unavoidable but we must not forget that we all have a stake in global financial stability," Lagarde said Sunday.
"Given the cross-border spillover effect of monetary policy decisions, central banks may need to step up their international dialogue and cooperation.
"It is important for us to stay at the table and work through these issues."
During the Asian financial crisis in the late 1990s, Malaysia adopted capital controls designed to smooth volatility and prevent money flowing out of the economy as fast as it had arrived, sparking protest among many free-market critics.
