Japan's Core Inflation Drops to 1.4% in April, Weakening Rate Hike Case

Japan's core inflation eased more than expected in April to its lowest level since March 2022, potentially weakening the case for an early rate hike by the Bank of Japan.

Core inflation — which strips out prices of fresh food — came in at 1.4%, lower than the 1.7% expected by economists polled by Reuters and below the 1.8% reading in March.

Headline inflation was at 1.4%, down from March's 1.5% and the fourth straight month below the central bank's 2% target.

The so-called "core-core" inflation rate, which is watched by the Bank of Japan and strips out food and energy prices, fell to 1.9% from 2.4%.

Energy prices fell 3.9% in April compared with a 5.7% decline in March, amid the Iran war.

Japan's Nikkei 225 opened up 0.96% following the data release, leading major Asian indexes, while the yen weakened marginally to 159.03 against the dollar.

The Bank of Japan sharply raised its core inflation outlook to 2.8% from 1.9% at its April meeting, citing higher crude oil prices linked to the conflict in the Middle East and businesses passing on higher costs to consumers.

The data also follows reports that Prime Minister Sanae Takaichi signaled she was open to a supplementary budget to address rising energy costs.

According to Japanese public broadcaster NHK, opposition lawmakers had proposed a 3 trillion yen ($18.8 billion) package, including an extension of petrol subsidies and relief for electricity bills.

Japan is currently struggling with a weak yen, having reportedly spent 10 trillion yen on intervening in the yen at the end of April and the start of May. A weak currency has increased import costs and eroded consumers' purchasing power.

Still, a BOJ rate hike may be on the horizon, as the country's economy seems to be holding up, posting a better-than-expected 2.1% annualized expansion in the first quarter of 2026.

The growth was partly powered by strong exports, which could give the BOJ confidence to hike rates, according to DBS analysts in a Thursday note.
