According to a Bank of Japan (BOJ) report issued Friday May 15, Japan’s wholesale prices jumped 4.9% year-on-year in April. This number exceeds the 3.0% gain economists had forecast and nearly doubled March’s revised 2.9%, as the Iran conflict drove a sharp rise in oil and petrochemical import costs, Reuters reported.
The corporate goods price index (CGPI), which tracks what companies charge each other for goods, caught markets off guard. But beyond the headlines, yen-denominated import prices were even more revealing. Import prices rose 17.5% in April from a year earlier, nearly double its pace in March at 8.0%.
The cause: The war in Iran and the closed Strait of Hormuz. The resulting effect has seen crude prices spike, the dollar trading higher against the yen, driving up costs for Japan’s fuel-dependent economy.
Japanese manufacturers and retailers are passing cost increases to consumers faster than in previous oil shocks, per Nikkei Asia. Prices for petroleum products, chemicals, metals, and food have all risen.
Snack maker Calbee switched to black-and-white packaging amid an ink shortage tied to petroleum-derived solvent scarcity. Auto parts makers face soaring aluminum and plastics costs. Tech suppliers are not left out, with Helium shortages biting hard.
Three BOJ dissenters wanted to hike before this data landed
The BOJ held its rate at 0.75% at its April 27-28 meeting on a 6-3 vote. Board members Hajime Takata, Naoki Tamura, and Junko Nakagawa pushed for 1.0%.
The April summary of opinions, released May 11, showed one member calling for the central bank to raise rates “without hesitation” if inflation risks grew. Today’s 4.9% print validates that position.
The BOJ had already raised its FY2026 inflation forecast to 2.8% from 1.9% while cutting growth to 0.5% from 1.0%.
Barclays OIS pricing puts the probability of the June hike at 74%. As Cryptopolitan reported in January, Governor Ueda has signaled a willingness to keep raising rates.
Every BOJ hike since 2024 has triggered a Bitcoin selloff
The July 2024 hike to 0.25% sent Bitcoin from $65,000 to $50,000 in a week. Also in January 2025, a rate hike to 0.50% resulted in a 25% to 31% drop in the price of BTC over 20 days.
If the June hike materializes, crypto traders with leveraged yen-funded exposure may face a repeat of the same.
The BOJ meets June 16-17. If wholesale inflation is still running at this pace when the board convenes, the three dissenters from April will have the data on their side.
