Tankan: Large Japanese firms more optimistic despite Iran conflict

The Bank of Japan’s closely watched Tankan indicators for the March period signalled stronger-than-expected optimism among large manufacturers, with Reuters’ Tankan poll showing a notable uptick in sentiment driven by chemicals, petroleum and semiconductor-related demand.

Reuters reports the poll was conducted between March 4-13, surveying 492 major non-financial companies of which 216 responded; the manufacturers’ sentiment index rose significantly month-on-month while a number of subsectors—such as paper and pulp—reported a more cautious stance.

Despite the upbeat readings, market commentators emphasise that the survey window closed in March and may not capture the full impact of the escalating Iran conflict. Several respondents noted a “wait-and-see” attitude among customers, and Reuters highlights firms’ concerns about rising costs and geopolitical-driven demand uncertainty. These caveats underpin analyst warnings that the current optimism could be short-lived.

The Associated Press’ coverage of the Bank of Japan’s official Tankan release complements the picture, noting that while large non-manufacturers remained relatively positive, energy price volatility and a weaker yen could feed through to consumer prices and complicate the BoJ’s policy calculus; AP also reported the BoJ held its policy rate steady in March.

From a market perspective, strategists say the Tankan’s March readings offer a snapshot of corporate sentiment but urge caution: a sustained increase in oil prices or renewed demand weakness out of China would likely weigh on capital expenditure plans and could prompt a reassessment of the BoJ’s rate path. Analysts expect the coming months’ data—oil, USD/JPY moves and Chinese demand indicators—to determine whether the recent optimism endures.
