Global oil prices fell sharply and Asian markets stumbled on Monday following two major global developments potential US-Iran peace talks and a rare joint currency intervention by the US and Japan.
Brent crude futures dropped over 4% to $83.88 a barrel. This decline followed US President Donald Trump’s announcement of upcoming talks with Iran halting an imminent military strike in an effort to reopen the Strait of Hormuz and address Tehran's nuclear program. Consequently the drop in oil prices eased bond markets, pushing the 30-year US Treasury yield down to 5.238%.
Simultaneously the Japanese yen strengthened 0.5% against the US dollar to 156.47. This recovery was triggered by a coordinated intervention from Washington and Tokyo to rescue the yen from a 40-year low.
US Treasury Secretary Scott Bessent supported the move stating the US might expand its repurchase facility to ensure temporary dollar liquidity. President Trump noted the US assisted Japan as a gesture of economic friendship.
Despite the currency stabilization Asian stock markets struggled. Japan's Nikkei fell nearly 2%, and South Korea's KOSPI dropped over 4%, driven by investor anxiety regarding massive artificial intelligence capital spending and delayed returns. Conversely US and European stock futures experienced modest gains.
While the joint US-Japan intervention offered immediate relief for the yen, market experts cautioned that long-term sustainability will require significant changes in fundamental monetary policy.
