Most Latin American currencies weakened on Friday, joining European emerging market peers in taking a breather, as the dollar rallied strongly after US inflation rose more than expected.

Emerging market currencies had gained ground this week, taking an index of developing country currencies to all-time highs. The US dollar strengthened on Friday and was on track for a weekly gain after new US data confirmed expectations about inflation.

Brazil's real bucked the trend, erasing early losses to rise 0.4%. The currency extended gains to a third straight session with iron ore prices rising. Shares in iron ore miner Vale rose 0.3% and were among top gainers on Sao Paulo's main stocks index.

The real currency is up about 2.5% for the week, taking monthly gains closer to 4%.

This took weekly gains close to 3%, the most among Latam stocks benchmarks.
