Asian equities surged following the release of US inflation figures showing a notable monthly decline, an outcome that lessened expectations of an imminent Federal Reserve rate increase. This development energized markets across the region, with South Korea’s KOSPI index leading the advance thanks to strong gains in semiconductor stocks.
The US Consumer Price Index (CPI) for June fell by 0.4% from May, marking the steepest drop since April 2020, while the year-over-year increase stood at 3.5%, signaling a moderation in inflationary pressures. Core inflation also surprised on the downside, prompting investors to price in just a 16% probability of a rate hike at the Fed's upcoming July meeting. This recalibration reflects growing market confidence that the central bank will pause rate hikes to better assess inflation trends.
The effects were most pronounced in South Korea, where the chip-heavy KOSPI index jumped more than 6%, with SK Hynix shares soaring roughly 10%. This rally was fueled by renewed investor optimism about the chip sector, driven by expected artificial intelligence demand and a less aggressive interest rate outlook—a scenario that favors growth-oriented tech stocks.
Japan’s Nikkei also rose, buoyed by the broader regional momentum tied to easing inflation concerns in the US and solid early earnings reports from American banks. These corporate results alleviated some uncertainty, reinforcing investor appetite for risk despite ongoing questions about monetary policy direction.
Meanwhile, energy markets added complexity to the picture as oil prices extended gains for a third straight day amid geopolitical tensions, introducing additional volatility that investors are monitoring closely. For Asian markets, the softer US inflation data presented an uncommon window of relief, suggesting borrowing costs might remain lower for longer—an environment supportive of higher valuations and more active capital flows across the region.
