Mr Strauss-Khan says the entire monetary system is beginning to come under strain.

He has pointed to the strong euro, the weak Japanese yen and Chinese yuan and a US dollar that he says is somewhere in between.

He says that has led to a situation of increasing market tension and has created problems for economic growth.

Mr Strauss-Khan says IMF forecasts to be released in the coming weeks will be weaker than previous estimates for the United States, Europe and emerging market countries.
