Venezuela's stock market, the IBC Index, experienced a dramatic surge of approximately 50% in a single trading session, following the arrest of President Nicolas Maduro after a US military operation. This rally, part of a larger upward trend, has led to significant gains over recent months and years. Investors are interpreting Maduro's capture and potential US involvement, including an oil export deal, as a possible turning point for the nation's economy, anticipating potential sanctions relief and a shift towards more private investment, though underlying economic challenges like high inflation persist.
