The Mexican currency (peso) dropped on concerns that demand for Mexican exports will drop, the fall in the peso came after Federal Reserve Chairman Ben Bernanke announced a deteriorating U.S. economy.

The fall in the Mexican currency wiped out early gains that were fueled by the expectation that the Mexican central bank will maintain its benchmark interest rate at 7.5% tomorrow.

Investors expect the Peso to bounce back due to the widening gap in the difference between the U.S. and Mexican interest rates, with Mexican assets looking increasingly attractive.

Bernanke explained that credit becoming more expensive and less available was causing economic growth to be restrained. He went on to state that the downside risks to growth have increased and the outlook for the economy has worsened in recent months.

It is anticipated that Banco de Mexico will begin to cut rates soon, possibly as early as next month, in an attempt to boost economic growth.
