Japan's core inflation cooled to its lowest reading in four years during April, reducing expectations that the Bank of Japan will need to tighten monetary policy further in the near term. Asian equity markets moved higher alongside the data, supported by cautious optimism around regional peace talks. Separately, Japan received its first Persian Gulf oil shipment to clear the Strait of Hormuz since the outbreak of the Iran conflict, signaling a tentative reopening of a critical energy supply route.
Slower inflation gives the Bank of Japan room to hold interest rates steady rather than hike further — a meaningful relief for Japanese equities, which have been sensitive to any shift away from the country's historically loose monetary policy. For global investors, the resumption of Gulf oil flows through the Strait of Hormuz reduces one of the more acute energy supply risk premiums that has been embedded in oil prices. Both developments lean modestly bullish for Japanese stocks and mildly bearish for crude.
