Asian equities broadly opened lower on Monday, impacted by AI giants' calls to slow the pace of frontier model development and renewed inflation concerns fueled by soaring oil prices. South Korea's KOSPI index fell over 3%, with SK Hynix down more than 5% and Samsung Electronics down over 3%. Japan's Nikkei 225 index extended its decline to 2%, and SoftBank's stock plunged 11%.

In energy markets, Brent crude rose over 3% to $107.99 per barrel, as Saudi Arabia shut down a key oil pipeline and Oman postponed a meeting with Iran and other countries originally scheduled for today, intensifying market concerns about the inflation outlook. Swap market pricing indicates that the probability of the Federal Reserve raising interest rates this Wednesday has exceeded 90%.
