Major Latin American currencies fell against the dollar on Thursday as global trade tensions strengthened the greenback and political uncertainty in Brazil and Argentina. Latin America's largest economy heads into a presidential election in two months time and in Argentina a major corruption scandal is unfolding.

Brazil's auto exports tumbled 21% in July from a month ago, the country's automakers' association said on Tuesday, blaming a monetary crisis in neighboring Argentina for the shortfall and adding that it expects exports to be steady for the year, not higher as it had predicted before last month.

Inflation in Brazil slowed for the first time in two months in July as the impact of a May nationwide truckers' strike dimmed, reinforcing the view that a recent price spike would not last long.

Venezuela’s state-run oil company PDVSA has limited the damage from an unprecedented slump in crude exports by transferring oil between tankers at sea and loading vessels in neighboring Cuba to avoid asset seizures.

Cuba said this week it was doubling the amount of land it granted would-be farmers and the lengths of their leases in an effort to increase stagnating agricultural output.

Argentine farmers are finishing this year's wheat sowing, helped by moist soils and cold weather that is prolonging the vegetative stage of crops, raising hopes of high yields and a record harvest, growers and analysts said on Wednesday. Cold Southern Hemisphere winter weather allows seedlings to grow more sprigs per plant. Harvesting starts in November.

The pound has fallen below US$1.29 for the first time in almost a year on continuing worries Britain will leave the EU without a trade deal. Sterling also hit a nine-month low against the euro, and was down against the yen and Swiss franc.

British farmers have called on the government to make food security a top priority on the day the country’s cupboards would run bare if households relied only on British produce. A long-term decline in self-sufficiency that has stagnated at around 60% in recent years means around three quarters of the shortfall is imported from the rest of the European Union.
