SynopsisJapan's core inflation eased to a four-year low in April, driven by government subsidies. However, rising energy costs due to the Iran conflict are expected to push inflation higher, prompting speculation of further monetary tightening by the Bank of Japan.APBank of Japan policymakers have recently shifted focus toward balancing inflation risks against the impact of higher borrowing costs on economic growth.Japan’s annual core inflation slowed to a four-year low in April as government subsidies on fuel and education helped ease price pressures, although rising energy costs linked to the Iran conflict are expected to push inflation higher again in the coming months, according to Reuters.Data released on Friday showed Japan’s core consumer price index (CPI), which excludes volatile fresh food prices, rose 1.4% year-on-year in April compared with 1.8% in March. The reading was also below market expectations of 1.7% and marked the slowest pace of increase since March 2022.A sharp decline in education fees, down 10.6%, weighed on overall service-sector inflation and offset continued increases in food and other consumer goods prices. Another key inflation gauge closely monitored by the Bank of Japan (BOJ), which excludes both fresh food and fuel, rose 1.9% in April compared with 2.4% in March, indicating some moderation in underlying price pressures.Despite the softer inflation data, analysts expect the trend to reverse as higher crude oil prices triggered by the Middle East conflict begin feeding into Japan’s economy. The closure of the Strait of Hormuz has disrupted a major global energy supply route, pushing up oil prices and increasing imported inflation risks for Japan, which relies heavily on Middle Eastern fuel imports.According to Reuters, rising wholesale prices for oil and chemical products have already accelerated producer inflation in April, strengthening expectations that the BOJ could continue tightening monetary policy. Markets widely expect the central bank to raise its short-term policy rate to 1% from 0.75% at its June policy meeting.BOJ policymakers have recently shifted focus toward balancing inflation risks against the impact of higher borrowing costs on economic growth. Board member Junko Koeda indicated that the central bank is carefully monitoring how rising wholesale costs pass through to consumer prices, while also assessing the broader economic trade-offs of further rate hikes.Investors are now closely watching BOJ Governor Kazuo Ueda, who is scheduled to speak on June 3, for signals on the likelihood and pace of future interest-rate increases.Impact on Markets and StocksThe softer inflation reading initially reduced pressure on the BOJ to tighten policy aggressively, which could support equities by keeping borrowing costs relatively contained in the near term. However, rising energy prices and expectations of future rate hikes are creating sector-specific volatility in Japanese markets.Positive ImpactExport-oriented companies such as automakers and technology firms may benefit if the yen remains weak against the dollar.Japanese banks could gain from expectations of higher interest rates improving lending margins.Energy producers and trading houses may see earnings support from elevated oil prices.Negative ImpactAirlines, transport companies and fuel-intensive industries may face margin pressure due to higher crude prices.Consumer-focused companies could see weaker spending if inflation accelerates again.Rate-sensitive sectors such as real estate and utilities may come under pressure if borrowing costs continue rising.Global investors are also monitoring the BOJ’s policy direction because a faster pace of Japanese rate hikes could influence global bond yields, currency markets and foreign investment flows across Asian equities.Read More News on(What's moving Sensex and Nifty Track latest market news, stock tips, Budget 2025, Share Market on Budget 2025 and expert advice, on ETMarkets.
