    Dec 15 (Reuters) - Mexico's peso stabilized on Tuesday after
a four-day slide as investors eyed a debate over a hotly
contested central bank bill, while other Latin American
currencies gained footing on optimism around COVID-19 vaccines
and higher oil prices. 
    The Mexican peso gained 0.2% to trade at 20.1978 per
    The lower house of Mexico's Congress on Tuesday will debate
the bill that critics say would force Mexico's central bank to
accept money from drug gangs, lawmakers said, and the measure
could go to a vote on the same day.
    Ratings agency Moody's warned late on Monday that the reform

    The oil exporter's currency hit a March high versus the
dollar last week, aided by stronger crude prices, hopes of

Chilean pesos firmed against the dollar, weakened by
hopes of more U.S. coronavirus relief aid.  
    Minutes of Brazil's latest central bank meeting showed
policymakers see inflation staying high in December due to
temporary shocks. Central bank President Roberto Campos Neto
said the country's economic recovery, which he described as
V-shaped, has started to lose steam.
    The real had rallied last week after policymakers said they
could "soon" drop a pledge to keep rates lower for longer amid a
spike in inflation. 
    The currency of the world's largest copper producer, Chile, 
 gained 0.1% as copper prices firmed, supported by strong
factory data from China, the world's top metal
