SAO PAULO, March 13 (Reuters) - Latin American equities posted slight losses on Tuesday, as Brazilian bank stocks slid on the possibility of another interest rate cut and investors weighed the fallout from the firing of U.S. Secretary of State Rex Tillerson.
Tillerson's ouster was generally shrugged off by markets, as analysts said traders have grown increasingly immune to political turmoil under President Donald Trump.
In Brazil, lenders Itaú Unibanco Holding SA, Banco Bradesco SA and Banco do Brasil SA all fell about 1.5 percent, accounting for nearly half the 0.7 percent decline of the benchmark Bovespa stock index.
Longer-term Brazilian interest rate futures continued to decline despite stronger-than-expected retail sales data, weighing on the outlook for bank earnings, according to traders.
"Stronger retail sales doesn't change the perception that the central bank is going to cut the Selic (benchmark interest rate) in March," said Flavio Serrano, a senior economist at Banco Haitong.
Stocks benefitting from lower borrowing costs in Brazil gained on the interest rate outlook, including a 1.6 percent rise for toll road operator CCR SA and an index-leading 2.8 percent gain for homebuilder MRV Engenharia e Participações SA.
Elsewhere in Latin America, Mexico's IPC index was roughly flat in morning trade, while Chile's IPSA ticked down a modest 0.12 percent.
Profit-taking on technology stocks weighed on Wall Street's main indexes after strong gains so far this year.
