Mexican peso at four-month peak

The Mexican peso firmed on Friday to its strongest in four months ahead of a key vote on the US healthcare overhaul plan seen as a test of President Donald Trump's self-described skills as a negotiator. The peso strengthened 0.5 percent, touching levels last seen before Trump was elected in November. Other Latin American currencies also edged up in thin trading volumes.
Bets that Trump's campaign pledges to cut taxes could raise economic growth in the world's No. 1 economy had lifted appetite for emerging market assets earlier this year.
But the rally fizzled on Wednesday after his healthcare bill stalled in Congress, raising doubts about the president's ability to work with Congress.
