EMERGING MARKETS-Latam stocks, FX fall as U.S. dollar firms

* Agrentina's Milei taps ex-central banker Caputo * Petrobras down on renegotiation of refinery sales pact * Stocks down 0.4%, FX off 0.3% By Shubham Batra Nov 29 (Reuters) - Latin American stocks and currencies fell on Wednesday as investors turned cautious after a rise in the U.S. dollar, with MSCI's gauge of the region's currencies down 0.3% and set to log its worst day in three weeks. Brazil's real slipped 0.3% after the central bank established new procedures for banks which imply an increase of 34 billion reais ($6.98 billion) in the total capital requirements of the financial system. Argentina's peso was down 0.1% against the dollar as Javier Milei met with top U.S. officials and his economic team huddled with IMF officers as the president-elect seeks to formulate a plan to lead the country's economy out of crisis. Milei said in a radio interview in Buenos Aires after a two-day trip to the United States that he will appoint Luis Caputo as his economy minister. Chilean peso was flat against the dollar. Chile's unemployment rate remained unchanged at 8.9% in the quarter to October, versus the 8.8% expected by economists polled by Reuters. Its benchmark stock index climbed 0.3%. "The uptick in the unemployment rate from a year ago has been driven more by a recovery in the participation rate than a deterioration in the labor market," economists at Goldman Sachs said in a note. Peru's sol fell the most in the region, slipping 0.4%. Emerging market assets are expected to see a rally through the year-end as U.S. Treasury yields slipped to multi-month lows on growing optimism about an interest rate cut from the Federal Reserve in early 2024. Regional stocks declined in early trade, falling 0.4%. Brazil's Bovespa index rose 0.1%, while the shares of Petrobras fell 0.4% after the state-run firm filed requests to local competition regulator Cade to renegotiate terms that stipulated the company must sell some of its oil refining and natural gas assets. Argentina's Merval index recovered some of its losses of the last two sessions, climbing 3.8% but 13% lower so far this week.
