Japan’s core inflation softened to 1.4% in April, its lowest level since March 2022, challenging the Bank of Japan’s hawkish stance. While energy subsidies and tuition costs contributed to the decline, the central bank eyes potential future inflation boosts from global conflicts and robust exports, maintaining a complex outlook for monetary policy.
Japan's core inflation unexpectedly eased in April to its lowest level since March 2022, potentially undermining the case for an imminent interest rate hike by the Bank of Japan (BOJ).
Key economic indicators showed a significant slowdown: Core inflation, which excludes volatile fresh food prices, registered 1.4%, falling short of Reuters economists' projection of 1.7% and down from March's 1.8%. The broader headline inflation also stood at 1.4%, marking the fourth consecutive month below the central bank's 2% target. Furthermore, the 'core-core' inflation rate, a key metric for the BOJ that strips out both food and energy costs, declined to 1.9% from 2.4%.
Energy prices, specifically, saw a 3.9% drop in April, a shallower decline than March's 5.7%, partly influenced by the Iran war.
Following the data release, Japan's Nikkei 225 index opened 0.96% higher, leading major Asian markets, while the yen marginally weakened to 159.03 against the U.S. dollar.
According to Andrew McCagg, a customer portfolio manager at Nomura Asset Management, speaking on CNBC's "Squawk Box Asia," the inflation figure was a "little bit of a surprise, but not too much of a concern." He attributed the dip below 2% partly to government fuel subsidies and, unexpectedly, to subsidies for school tuition. McCagg also noted that the ongoing Iran war is likely to push inflation higher in the coming months. He emphasized that, unlike other major economies, Japan's primary concern remains the risk of falling back into deflation, rather than inflation spiraling out of control.

The Bank of Japan, at its April meeting, had sharply raised its core inflation outlook to 2.8% from 1.9%, citing elevated crude oil prices due to Middle East conflicts and businesses passing on higher costs. This latest data complicates that revised outlook.
Further complicating the economic picture, Prime Minister Sanae Takaichi has signaled openness to a supplementary budget aimed at addressing surging energy costs. Opposition lawmakers have reportedly proposed a 3 trillion yen ($18.8 billion) package, including extensions of petrol subsidies and relief for electricity bills.

Japan is also grappling with a persistent weak yen, with reports suggesting approximately 10 trillion yen spent on currency interventions in late April and early May. A weak currency has inflated import costs, eroding consumer purchasing power.
Despite these deflationary pressures, a BOJ rate hike might still be on the horizon. The country's economy demonstrated resilience, expanding at a better-than-expected 2.1% annualized rate in the first quarter of 2026. This growth was partly fueled by strong exports, a factor DBS analysts believe could provide the BOJ with the confidence needed to consider tightening monetary policy.
