Bernard Arnault, chairman of LVMH, became the fourth-richest person in the world this week as his net worth surged by $6.2 billion after LVMH’s stock rose 4% due to new economic stimulus measures from China. Arnault, who owns about half of LVMH, had previously seen a decline in his wealth this year amid stock struggles and a tech rally. The recent gains follow the People’s Bank of China’s announcement of interest rate cuts and liquidity support to boost its struggling economy, which has been hampered by high youth unemployment and falling real estate values. Arnault’s net worth now stands at $183 billion, placing him just ahead of Oracle cofounder Larry Ellison’s $179 billion, but behind Mark Zuckerberg, Jeff Bezos, and Elon Musk.
