MEXICO CITY, Aug 16 (Reuters) - Mexican Deputy Finance Minister Alejandro Werner, one of President Felipe Calderon's pointmen for pushing economic reforms, said on Monday he is stepping down from his post.

Werner is well respected on Wall Street and his presence smoothed over investors' concerns when Calderon named the relatively inexperienced Ernesto Cordero to head the ministry in 2009.

"I'm leaving," Werner said in an e-mail to Reuters, without elaborating on the reasons for his departure.

A Mexican radio station said Werner would be replaced by Jose Antonio Meade, the ministry's senior official for revenue. Meade holds a doctorate in economics from Yale University.

Luz Padilla, a portfolio manager for the DoubleLine emerging markets fixed income fund in Los Angeles, said she was not fretting over Werner's exit.

"He is very good but I think Mexico has a lot of other very good people in the government. So from the perspective of policy, I don't see any changes coming and looked at it as a kind of neutral announcement," she said.

Analysts at RBC Capital Markets said Werner's exit should not effect markets or the government's prospects for pushing reforms in Congress.

"The appointments should not be market-moving," RBC said in a note to clients.

Calderon is due to submit a budget proposal next month that might include a proposal to boost the country's weak tax take, though politicians and political analysts do not expect Congress to back substantial economic reforms this year.

Mexico's peso did not appear to move on the reports, but was 0.4 percent stronger as investors snapped up Mexican peso-denominated bonds, traders said. (Additional reporting by Daniel Bases in New York; editing by Todd Eastham)
