MEXICO CITY, Feb 25 (Reuters) - The Mexican peso slipped on Wednesday and stocks fell amid uncertainty about how the new U.S. administration will be able to aid struggling banks and revive the economy, which consumes most of Mexico's exports.

The peso MXN= MEX01 weakened to 14.95 per dollar. Earlier in the day, it was down 0.35 percent at 14.89 per dollar at the central bank's 1:30 p.m. local time (1730 GMT) final reference.

The peso MXN= MEX01 weakened to 14.95 per dollar, but was off earlier lows down 0.35 percent at 14.89 per dollar at the central bank's 1:30 p.m. local time (1730 GMT) final reference.

The benchmark IPC stock index .MXX closed down 0.52 percent at 18,200.70 points.

Stock markets worldwide fell after an address before Congress by U.S. President Barack Obama on Tuesday night provided few clues as to how he would shore up battered banks or pull the economy out of recession.

"As long as there is no clarity about what will happen with the U.S. banking system, they won't be able to thaw credit channels and so the economic recovery will take longer," said Miguel Angel Flores, an analyst at government bank Bansefi.

Economists say Mexico's economy is slipping into recession due to the downturn in the United States, which buys around 80 percent of Mexican exports.

Mexico's peso has lost around a third of its value against the dollar since early August as the global financial crisis hit emerging markets.
