LONDON, England - May 26, 2010 - The M3 money supply in the United States is contracting at an accelerating rate that now matches the average decline seen from 1929 to 1933, despite near zero interest rates and the biggest fiscal blitz in history.

The M3 figures - which include broad range of bank accounts and are tracked by British and European monetarists for warning signals about the direction of the U.S. economy a year or so in advance - began shrinking last summer. The pace has since quickened.

The stock of money fell from $14.2 trillion to $13.9 trillion in the three months to April, amounting to an annual rate of contraction of 9.6%. The assets of insitutional money market funds fell at a 37% rate, the sharpest drop ever.

"It’s frightening," said Professor Tim Congdon from International Monetary Research. "The plunge in M3 has no precedent since the Great Depression. The dominant reason for this is that regulators across the world are pressing banks to raise capital asset ratios and to shrink their risk assets. This is why the U.S. is not recovering properly," he said.
