* Brazil's real reverses declines from earlier in session * Mexican, Colombian pesos fall on tumbling oil prices * Argentina c.bank raises reverse repo rates, keeps benchmark (Updates prices throughout; Adds bullets) By Shreyashi Sanyal Oct 29 (Reuters) - Most major Latin American currencies steadied on Thursday after a sharp selloff in the previous session, while currencies of oil-exporters including Mexico and Colombia extended declines on tumbling crude prices. Brazil's real edged 0.1% higher, a day after the country's central bank kept its key interest rate at a record-low 2.00%, maintaining its "forward guidance" pledge to keep rates lower for longer and even the possibility of further easing, despite the recent rise in inflation and fiscal risks. "The tone of the accompanying statement was a bit less dovish than the previous one," said William Jackson, chief emerging markets economist at Capital Economics. "Yesterday's statement also put more emphasis on the risk of looser fiscal policy as an asymmetric (upside) risk to the inflation outlook." In an analysis by Reuters, a Biden victory in next week's election could put the environment and human rights at the top of the country's agenda with Brazil, complicating relations with Brazilian President Jair Bolsonaro and jeopardizing trade, diplomats. The mood was still subdued after the dollar extended gains as worries remained about Europe's second wave of coronavirus infections and traders were pricing in the possibility of Democratic candidate Joe Biden winning the U.S. election on Nov. 3. Mexico's peso fell 0.6%, while the Colombian peso dropped 0.2% with oil prices 4% lower. Mexico's currency has fared somewhat better than other Latin American units due to the country's close trade ties with the United States and analysts say a Biden win would be the most favorable outcome for the Mexican peso. Investors awaited a central bank policy decision in Colombia on Friday, with expectations the bank will hold interest rates steady. A Reuters poll showed expectations for Colombia's 2020 inflation rose versus last month as economic conditions began to normalize, although estimates remain far below the central bank's target. The Chilean peso firmed 0.1% even as prices of its main export, copper, slipped on Thursday. Market participants watched as the country embarked on its path to reframe its constitution this week. Argentina's central bank raised its reverse repo rates while holding the benchmark Leliq rate unchanged, a market filing from the bank, seen by Reuters and confirmed by a bank official, showed. The country's economy is expected to contract 12% this year, with dwindling foreign reserves and capital controls creating a wide gap between the official peso rate and trades in alternative markets.
