Swiss trading house Mercuria posted a record $1.3 billion profit last year. Its success stemmed from well-timed copper market bets that capitalized on extreme volatility. The firm's aggressive trading strategy delivered outsized returns when metals prices swung wildly.

The result underscores the power of commodity trading houses during market turbulence. Mercuria, like its rivals, profits from price swings between producers and consumers. Its minimal tax bill further boosted the bottom line, a common structure for these global entities.

This profit surge highlights the sector's resilience despite economic headwinds. Investors will watch how Mercuria deploys this capital and whether its copper positions can repeat in a calmer market. The trading house's performance sets a benchmark for the industry.
