Iran war complicates policy: higher inflation vs weaker growth

Consumer confidence deteriorating sharply, adding downside risk
Japan’s wholesale inflation accelerated in March, reinforcing signs that cost pressures are broadening across the economy and sharpening the policy challenge for the Bank of Japan as it weighs its next move.The corporate goods price index rose 2.6% year-on-year, exceeding expectations and picking up from the prior month, while monthly price growth also strengthened. The data points to a widening pass-through of higher input costs, with firms raising prices across sectors including machinery and food as energy, metals and chemical costs climb. A key driver has been the sharp rise in import prices, which surged nearly 8% year-on-year. This reflects the impact of the Iran conflict on global energy markets, with oil prices rising significantly amid disruption to flows through the Strait of Hormuz. For Japan, which remains heavily dependent on imported fuel, the shock is feeding quickly into upstream pricing.Financial markets have responded by pushing yields higher, with shorter-dated government bond yields hitting record levels. Rate expectations have also shifted, with investors now assigning a meaningful probability to a near-term policy tightening.However, the policy outlook is far from straightforward. Bank of Japan Deputy Governor Ryozo Himino stressed that the economy is not currently in stagflation, noting that inflation remains around target and growth is still holding above potential. Nevertheless, he acknowledged that a prolonged conflict could create a difficult trade-off, with rising inflation coinciding with weakening economic activity.This dilemma is already beginning to take shape. While price pressures are building, consumer sentiment has deteriorated sharply, reflecting the strain of higher fuel costs on households. This suggests that the inflation impulse is being driven more by external shocks than by strong domestic demand.For the BoJ, the path forward hinges on how persistent the current shock proves to be. A temporary spike in costs may not warrant aggressive tightening, but a sustained period of elevated energy prices could push inflation higher while eroding growth—forcing a more complex policy response.In short, Japan is not yet in stagflation, but the risks are rising, and the central bank is increasingly navigating a narrow path between inflation control and economic support.
