    May 26 (Reuters) - Chile's peso rebounded on Wednesday from
a two-day decline as copper prices rose on a planned labor
strike at the world's biggest copper mine, while stronger
economic growth in Mexico supported its peso.
    The Chilean currency added 0.5% against the dollar
after a union representing workers at BHP Group's
Escondida and Spence copper mines rejected the company's
contract offer and urged members to walk off the job from
Thursday, threatening already low global supplies of the red
metal.
    "Copper-producing countries are likely to increase taxation
on miners, with Chile having already proposed substantially
higher royalties," analysts at Deutsche Bank wrote in a client
note.
    MSCI's index of EM currencies dipped 0.1%,
while Mexico's peso rose 0.2% to 19.880 per dollar. 
    Data released on Wednesday showed Mexico's economy grew
faster in the first quarter than earlier estimated as the
country slowly recovers from its sharpest contraction since the
1930s.
    "We estimate a better performance of GDP from (the second
quarter onwards), mainly driven by the expansion of the U.S.
economy, as domestic demand should remain on a more gradual
recovery trend; we thus maintain our 2021 GDP growth forecast at
5.1%," said strategists at Citi Research. 
    The upcoming midterm elections in Mexico may cause "noise"
but the peso exchange rate was expected to remain stable in the
range of 19.9 to 20.1 to the dollar, Mexican Deputy Finance
Minister Gabriel Yorio said on Tuesday.
    Brazil's real rose 0.5%. Late on Tuesday, Brazil's
Economy Minister said the local economy might grow by as much 5%
this year.
    The real is down almost 2.3% this year, with concerns about
fiscal spending being one of the main factors weighing on
sentiment.
    Meanwhile, a Reuters poll showed Brazil's equity market is
on course for its second slowest year since 2015 as the
coronavirus pandemic continues unabated in Latin America's
biggest economy.
    Sao Paulo's benchmark equity index was up 0.6%, with
airline Gol rising 6% after it cited an improvement
in May domestic ticket sales, driven by advances in Brazil's
COVID-19 vaccination program.
    Smaller rival Azul SA topped the index. A source
told Reuters Azul had approached Chile's bankrupt LATAM Airlines
Group with the aim of buying its Brazilian operation.

    Peru's sol fell 0.8% to a new low with less than two
weeks to go before a second round of presidential elections.
Recent polls show front-runner and socialist Pedro Castillo with
a growing lead over business-friendly conservative Keiko
Fujimori.
    Colombia's peso eased its fall as oil prices
steadied, while the stock index was flat with oil
major Ecopetrol hitting three-week lows. 
    Ecopetrol on Wednesday said social unrest in Colombia over
tax reforms had adversely impacted its operations.
