Asian stock markets fell on Wednesday, May 13, 2026, after a hotter-than-expected U.S. inflation report and ongoing Middle East tensions weighed on risk appetite. MSCI’s broadest index of Asia-Pacific shares outside Japan slipped 0.6%, extending losses for a second session. Japan’s Nikkei 225 was down 0.2%, while South Korean shares dropped as much as 3.2% before paring declines.
U.S. equity futures also eased, following a soft Wall Street close. Investors focused on the inflation data as a signal that price pressures may remain sticky, keeping the Federal Reserve on a more restrictive path than markets had expected earlier this year.
In rates and currencies, the yield on the U.S. 10-year Treasury was unchanged at 4.469%, its highest level since July. The U.S. dollar index rose for a third straight day and held at 98.322.
Rate expectations shift after inflation surprise
The April U.S. consumer inflation report showed the biggest increase in three years, prompting investors to reassess the outlook for Fed policy. Markets have largely priced out the chance of a rate cut this year, according to Fed funds futures tracked by CME’s FedWatch Tool.
Expectations for a 25 basis point rate increase at the Fed’s December meeting rose to more than 35% from below 22% earlier in the week. The shift in expectations contributed to a cautious tone across Asian markets, particularly in segments that had led recent rallies.
Oil stays elevated as US-Iran talks stall; Samsung falls
Geopolitics added to investor unease as talks between Washington and Tehran remained at a standstill, keeping energy prices high. Brent crude slipped 0.6% to $107.13, after holding at or above $100 a barrel since late February.
In Seoul, Samsung Electronics shares fell 5.7% after the company failed to reach a wage deal with its South Korean labor union, increasing the risk of a strike that could disrupt production of AI and other chips. The move weighed on the broader market after a recent AI-led rally.
Investors will continue to watch for updates on U.S. inflation and Federal Reserve messaging, as well as developments in the Middle East that could affect energy costs and broader risk sentiment.
