Japan's economy expanded an annualized 2.1 percent in the first quarter of 2026, surpassing the 1.7 percent market forecast, driven by robust exports and domestic demand, but faces significant headwinds from the escalating Iran war's energy shock.
The Bank of Japan (BOJ) will analyze this data to determine if the economy can withstand the energy crisis and allow for an interest rate hike as early as June. Yoshiki Shinke, senior executive economist at Dai-ichi Life Research Institute, states the economy possessed buffers before the Iran war, indicating its capacity to weather the energy shock, although a Q2 contraction is possible.
However, analysts at Oxford Economics expect growth to slow, citing high energy costs and uncertainty limiting consumption and investment. The Middle East conflict, including US-Israeli strikes on Iran and Tehran's closure of the Strait of Hormuz, has caused unprecedented global energy supply disruptions, sending prices soaring.
Japan, heavily reliant on Middle Eastern oil, faces rising inflation, eroding purchasing power, and tightening corporate margins. Economy Minister Minoru Kiuchi urged vigilance, and Stefan Angrick of Moody's Analytics predicts a "difficult year" ahead, despite modest fiscal support.
The yen weakened to 159 per dollar, prompting speculation of intervention by Tokyo, which previously spent approximately 10 trillion yen to support the currency.
