Japan's Nikkei 225 — a major stock index — fell over 3% on July 16, 2026, as semiconductor shares tumbled. The same day, the government sold bonds maturing in 5 to 40 years, flooding the market. Traders managing both stock and bond positions got squeezed, amplifying the swings. Notably, no single economic event caused it.
