Bank of Japan data released Friday showed the corporate goods price index (CGPI), which measures prices companies charge each other for goods and services, rose 4.9% in April from a year earlier, sharply exceeding market forecasts for a 3.0% increase.
The annual increase was the fastest since May 2023 and accelerated significantly from March’s 2.9% rise.

The figures underscored the growing impact of higher import costs on Japan’s economy following disruptions to oil shipments through the Strait of Hormuz amid the Iran conflict. Japan remains heavily dependent on imported energy, particularly crude oil from the Middle East.

The yen-denominated import price index jumped 17.5% in April from a year earlier, marking the steepest increase since December 2022 and reflecting both elevated global energy prices and the weaker yen’s effect on import costs.

On a monthly basis, wholesale prices rose 2.3% in April after increasing 1.0% in March, the data showed.
Petroleum and coal product prices climbed 5.3% from a year earlier as crude oil and jet fuel costs rose, while chemical goods prices surged 9.2%, the strongest increase since September 2022. Naphtha prices soared 79.4%, according to the report.

The data came a day after a Bank of Japan policymaker called for raising interest rates “at the earliest stage possible” to contain inflationary pressures stemming from higher fuel costs and supply disruptions linked to the Middle East conflict.

Economists said the breadth of price increases would be closely monitored by policymakers assessing whether inflation pressures are becoming more entrenched across the broader economy.

“If price rises are contained to oil-related goods, there is little need for the BOJ to respond,” said Masato Koike, senior economist at Sompo Institute Plus.
“But if they broaden to a wide range of goods, the BOJ will likely have to raise rates,” he said.

The inflation surge adds to pressure on the central bank as it seeks to normalize monetary policy after years of ultra-low interest rates and stimulus measures aimed at reviving growth and inflation.

Tokyo — Business sentiment among Japanese firms improved in the three months to March while corporate inflation expectations rose to record levels, a closely watched survey showed on Wednesday, strengthening the case for a near-term interest rate hike by the Bank of Japan, even as escalating fuel costs linked to the Iran conflict darken the economic outlook.

The central bank’s quarterly “tankan” survey indicated that large manufacturers’ sentiment index rose to +17 in March, slightly above market forecasts of +16 and up from +16 in December, marking its highest level since December 2021.

The improvement extended a fourth consecutive quarter of gains, suggesting that parts of Japan’s industrial sector have continued to recover despite mounting global uncertainties.

Sentiment among large non-manufacturers remained robust, with the index holding steady at +36, surpassing a median market forecast of +33. The strength in the services sector was supported by rising profits from price increases and a continued recovery in inbound tourism, according to the survey data.

A Bank of Japan official said resilient demand for artificial intelligence-related semiconductors and easing uncertainty over U.S. trade policy helped offset pressures from higher input costs and geopolitical tensions in the Middle East.

At the same time, the survey highlighted growing inflationary pressures within the corporate sector. Companies reported rising expectations for future price increases, reflecting the impact of higher fuel and raw material costs.

Analysts said this trend could provide additional justification for the central bank to move toward policy normalisation after years of ultra-loose monetary settings.Mari Iwashita, executive rates strategist at Nomura Securities, said the survey underscored mounting inflation risks driven by external shocks.

She noted that companies facing surging energy costs may increasingly pass those expenses on to consumers, reinforcing upward pressure on prices.The data comes at a critical juncture for the Bank of Japan, which is weighing whether to raise interest rates as early as this month.

Market participants have been closely monitoring the tankan survey as a key gauge of corporate sentiment and investment plans.Despite the relatively upbeat current conditions, the survey revealed growing caution among firms about the near-term outlook.

Both manufacturers and non-manufacturers expect business conditions to deteriorate over the next three months, reflecting concerns about the economic fallout from the Iran conflict and its impact on energy markets.

The ongoing conflict has driven up global fuel costs, increasing operational expenses for Japanese companies that rely heavily on imported energy. The resulting squeeze on margins is expected to weigh on profitability, particularly for industries with limited pricing power.

Marcel Thieliant, head of Asia-Pacific at Capital Economics, said the strength of the survey could still encourage policymakers to act. He noted that firms appeared to be absorbing the energy shock for now, suggesting that underlying economic conditions remain stable enough to support a rate hike in the near term.

Capital expenditure plans among large firms also pointed to cautious optimism. Companies expect to increase investment by 3.3% in the fiscal year 2026, exceeding a median market forecast of a 3.0% rise.

The planned increase suggests that firms are continuing to invest in growth despite heightened uncertainty.The survey period, which ran from February 26 to March 31, captured responses from roughly 70% of firms by March 12, shortly after the escalation of hostilities involving the U.S.-Israel attacks on Iran on February 28.

This timing indicates that early assessments of the conflict’s economic impact are already being reflected in corporate sentiment.Economists cautioned that the positive momentum seen in the survey may not be sustained if external conditions worsen.

Stefan Angrick said that while a weak yen and subdued wage growth have supported corporate margins, broader economic challenges remain.He noted that export growth could weaken amid slowing global demand, while domestic consumption may remain constrained by modest income gains.

Over time, these factors could weigh on corporate profits and sentiment, complicating the central bank’s policy decisions.The survey underscores the delicate balance facing policymakers as they navigate between emerging inflationary pressures and risks to economic growth.

While improving sentiment and rising prices strengthen the case for tightening monetary policy, the uncertain global environment, particularly developments in the Middle East, continues to pose significant challenges for Japan’s export-driven economy.
