EMERGING MARKETS-Argentina's Merval leads gains on high interest rates, oil prices


SAO PAULO, Nov 22 (Reuters) - Argentina's peso currency and Merval stock index registered solid gains on Wednesday after the nation's central bank held its benchmark interest rate and crude prices buoyed the nation's commodities-heavy equities market. On Tuesday evening, Argentina's central bank held its benchmark rate at 28.75 percent in order to fend of inflation that remains stubbornly high. That sent Argentina's peso up 0.22 percent and helped lift its main stock index more than 1 percent, aided by financial stocks that stand to gain from high interest rates. Argentine gas and energy distribution companies also registered strong gains as global crude increased amid supply disruptions in North America. Brazil's Bovespa index was roughly steady, as President Michel Temer continued to negotiate with allies to bring about a pension reform seen as key to shoring up the country's fiscal health. Those light gains came as buying slowed slightly, following three straight bull sessions, in which the Bovespa accumulated a rise of 5.3 percent. Chile's IPSA blue-chip index was the big loser among Latin America's equity markets, falling over 0.5 percent, as the strong performance of the nation's left in first round elections over the weekend continues to spook markets.
