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.

The country emphasized the importance of resisting tariff pressures and protecting the stability of global supply chains during a major economic dialogue in Beijing.

Premier Li Qiang urged global partners to avoid rising protectionism, stressing that cooperation remains the foundation of steady worldwide growth.

He said the global economy faces heavy strain from new trade restrictions, making it essential for governments and international organizations to safeguard free trade.

China met with leaders from major global institutions, including the IMF, World Bank, WTO, OECD and ILO, highlighting the need for better global governance.

The message focused on promoting fair competition, supporting emerging economies and ensuring that global markets remain open and accessible.

Li noted that increasing tariffs around the world are disrupting trade flows and affecting economic activity across developing and developed nations alike.

He reiterated that all countries benefit when supply chains function smoothly and when businesses can access overseas markets without excessive barriers.

China’s record trade surplus, driven by strong exports to Europe, Australia and Southeast Asia, has brought renewed attention to its role in global commerce.

While some nations call for reforms to balance global consumption, China stressed that it is committed to boosting domestic demand and diversifying its economic model.

Global leaders have recently engaged China on these issues, signalling the need for continued dialogue to prevent economic tensions from rising.

China, in turn, emphasized that long-term stability will come from collaborative efforts rather than unilateral tariffs or restrictive trade measures.

Experts say China’s push to expand trade ties with non-U.S. markets reflects its broader ambition to strengthen global commercial partnerships.

This diversification strategy is expected to create new investment opportunities, encourage innovation and support long-term economic resilience.

Analysts also note that China’s growing market offers vast potential for global companies looking to expand their presence in Asia.

With continued growth expected over the next five years, domestic demand may gradually help ease trade imbalances and create a more balanced global economy.

China reaffirmed its commitment to reforms that support sustainable development and high-quality economic expansion.

Officials highlighted ongoing investments in technology, infrastructure and green industries to ensure the economy remains competitive and resilient.

While some economists believe further policy adjustments could help stabilize global trade, most agree that cooperation is far more effective than confrontation.

They stress that coordinated action among major economies will help mitigate risks and promote shared prosperity.

China stated that it will continue to maintain open communication with its global partners and contribute to international economic stability.

Its leaders expressed confidence that dialogue, fairness and mutual respect will guide future trade discussions and reduce friction between major economies.

As global markets navigate complex geopolitical and economic challenges, China’s message focused on partnership rather than pressure.

The country called on all nations to work together to preserve free trade, reduce uncertainty and strengthen the global economic system.

By promoting cooperation and constructive engagement, China hopes to reassure investors, encourage innovation and build long-term trust across global markets.

The message underscored the need for shared responsibility in shaping a more balanced, open and prosperous international economy.
