(There will be no Latam-focused emerging markets report on Dec 25 because of the Christmas holiday) Dec 24 (Reuters) - The Mexican peso rose in thin pre-Christmas trading on Thursday, leading gains among Latin American currencies as the dollar weakened after the announcement of a post-Brexit trade deal. The Mexican peso rose 0.8% to a near 1-week high, with data showing the country"s seasonally adjusted unemployment rate up at 4.5% in November, compared with 4.7% in October. Of 12 million people who left the workforce in April because of the COVID-19 pandemic, some 9.9 million were back in employment by November, the national statistics agency said. Global markets found relief as the United Kingdom and European Union sealed a Brexit trade agreement a day before Christmas holidays in one of the most important deals in recent European history. That dented the safe-haven appeal of the dollar and boosted riskier emerging market currencies, including the Colombian and the Chilean pesos. Meanwhile, Mexico inoculated its first person against COVID-19, while the first 10,000 doses of a 10-million order of the Pfizer-BioNtech vaccine reached Chile. Stocks in the region were subdued, with markets in Brazil and Argentina closed on Thursday ahead of Christmas holidays.
