(Updates with final prices) By Bruno Federowski SAO PAULO, Oct 4 (Reuters) - Most Latin American stocks and currencies seesawed on Tuesday as investors reacted to local issues as well as rising oil prices and uncertainty over U.S. monetary policy. Crude oil prices drifted, rising early to hit four-month highs on optimism about an OPEC deal to freeze output levels, then fading as a surging dollar weighed on greenback-denominated commodities. The Mexican peso closed down 0.15 percent against the dollar, after strengthening earlier in the day. The Colombian peso weakened 1.64 percent, extending losses after voters rejected a peace deal with Marxist FARC rebels, and the Brazilian real fell 1.54 percent. Volatility has spiked in emerging markets over the last few months as traders seek to decipher the U.S. Federal Reserve's strategy for increasing interest rates. Contradictory comments by Fed officials have boosted uncertainty over when rates will rise for only the second time in a decade. Richmond Fed President Jeffrey Lacker said he would have voted in favor of an interest rate hike at the Fed's September policy meeting had he been able to vote, reflecting the growing pressure on Fed Chair Janet Yellen to raise rates. Brazil's benchmark Bovespa stock index seesawed. Shares of Itaúsa Investimentos Itaú SA weighed on the index on a report that it could make an offer for the fuel distribution unit of state-controlled oil company Petróleo Brasileiro SA. But other financial shares rose, providing some support.
