Japan’s Macroeconomic Dilemma Amidst the Strait of Hormuz Crisis

The conflict in the Middle East and the consequential closure of the Strait of Hormuz underscored Japan’s fundamental vulnerability to external energy disruptions stemming from its dependence on imported energy. Skyrocketing oil and gas prices and the risk of crude oil shortages placed additional pressure on an economy already constrained by decades of weak growth and deflation, high public debt, a depreciating yen, and an aging population. Rising energy and import costs threaten to intensify inflation, increase business operating costs, and weaken household purchasing power, creating cascading effects across multiple sectors of the economy.

In this landscape of anemic economic growth and rising energy prices resulting from the Iran-Israel conflict, Japan’s policymakers faced a difficult public policy dilemma. Fiscal and monetary measures, alongside exchange-rate considerations, could cushion the immediate impact on households and businesses, but each carried limitations, particularly given the country’s high public debt and fragile economic recovery. More importantly, short-term measures could not address Japan’s underlying dependence on imported energy supplies. In order to strengthen economic resilience, therefore, the country requires coordination between fiscal and monetary policy and longer-term efforts to diversify energy sources, strengthen domestic production capacity, and address demographic and structural constraints on growth. Japan’s experience demonstrates that the effectiveness of macroeconomic policy during an external disruption depends not only on the choice of individual policy instruments but also on how they interact with the economy’s fundamental structural conditions.
