# Asian Markets Fall Tuesday May 19: ASX -1.45%, Hang Seng -1.22% as Oil Hits $110 and Iran Ceasefire Wobbles

> **Quick answer:** Asian markets fell sharply on Tuesday May 19 2026. Australia's ASX 200 dropped 1.45% to close at 8,505 — its lowest level since April 1. Hong Kong's Hang Seng fell 1.22% and China's CSI 300 slipped 0.54%. Brent crude rose 0.79% to $110.12 after President Trump issued a fresh "clock is ticking" warning to Tehran and US forces destroyed IRGC patrol boats in the Strait of Hormuz. European markets open into the same headwinds. Wednesday is immediately worse: Nvidia earnings, FOMC minutes, Meta's layoff update, and Samsung results all land within hours of each other.

The ASX 200 posted its worst single-day drop since the ceasefire fears peaked in early May, the Hang Seng erased recent recovery gains, and traders across the region were left asking the same uncomfortable question: will the ceasefire survive until Wednesday?
