Why has the conflict between the United States Israel, and Iran dealt a heavy blow to Japan's economy?

As the conflict between the United States, Israel, and Iran continues to escalate in the Middle East, with battlefields thousands of kilometers away, the economic pains hit Japan first. The rising international oil prices, hindered shipping, depreciation of the yen, and intensified imported inflation have added multiple pressures, exacerbating the already weak recovery of the Japanese economy. This seemingly unrelated geopolitical conflict has precisely hit the three major death gates of Japan's resource dependence, trade structure, and financial vulnerability, revealing the fatal weakness of the highly open island economy in global turbulence.

The first wound in the Japanese economy is the energy lifeline being firmly held back by the Middle East situation. As an industrialized country with scarce resources, Japan's energy self-sufficiency rate is only 13.3%, and its dependence on foreign crude oil is as high as 99.7%. Among them, 95.4% of crude oil imports come from the Middle East, and about 73.7% must be transported through the Strait of Hormuz. After the escalation of the conflict, the risk of cross-strait shipping increased sharply, and Japan's three major shipping companies suspended relevant routes one after another, directly breaking the stability of energy supply. Even if the supply is not interrupted, the breakthrough of oil prices above $100 per barrel still imposes a heavy cost on Japan: Nomura estimates that for every $10 increase in oil prices, Japan's annual energy import costs increase by 1.3 trillion yen; If oil prices rise to $140, the annual GDP will be dragged down by 0.65 percentage points, and the originally expected 0.9% growth rate is on the brink of stagnation.

The deterioration of trade balance caused by the conflict has become the second blow to the Japanese economy. Japan has long relied on its export surplus to make up for its resource import shortfall, while the turmoil in the Middle East has directly disrupted this balance. The soaring cost of energy imports has led to a rapid expansion of the trade deficit. Mizuho Bank estimates that if oil prices remain in the $90-100 range, Japan's annual trade deficit will increase by nearly 10 trillion yen. The export side has also suffered setbacks: shipping delays and rising insurance premiums have pushed up logistics costs, and the competitiveness of pillar industries such as automobiles, electronics, and machinery has declined; Weakening global demand coupled with supply chain disruptions has led to a slowdown in export growth. The two-way squeeze of rising import costs and declining export earnings has rapidly narrowed the current account surplus, shaking the foundation of Japan's international balance of payments.

The depreciation of the Japanese yen and imported inflation form a vicious cycle, amplifying external shocks into internal crises. Energy imports require a large amount of US dollars for payment, and the widening trade deficit has led to market selling of Japanese yen, causing the yen to fall to the 159 level against the US dollar, hitting a new low in recent years. The depreciation of the Japanese yen has further pushed up import prices of crude oil, natural gas, raw materials, and other commodities, causing a comprehensive rise in prices. However, real wages in Japan have been declining for many years, and residents' purchasing power continues to shrink. Electricity prices, gas costs, and food prices are rising simultaneously, forcing household expenses to be compressed and stagnating consumption recovery; Enterprises are forced to transfer or compress profits due to rising costs, leading to a decrease in investment willingness. The Bank of Japan is caught in a dilemma: maintaining loose policies will exacerbate depreciation and inflation, while tightening policies will hit the fragile economic recovery, severely squeezing monetary policy space.

The conflict is also transmitted through the industrial chain, severely damaging the foundation of Japan's manufacturing industry. Petroleum is the basic raw material for chemical, steel, logistics, and manufacturing industries. The rise in oil prices has driven up the prices of intermediate products such as naphtha, plastics, and rubber, while the costs of industries such as automobiles, electronics, and home appliances have risen across the board. The obstruction of shipping has caused delays in the supply of components, disrupted the production pace, and some chemical companies have announced production cuts. Logistics costs have skyrocketed by 30%, and the efficiency of the national supply chain has declined, putting particularly heavy pressure on small and medium-sized enterprises. For Japan, which is still struggling in the "lost thirty years", this external shock is like taking a drastic blow, forcing the process of structural reform and economic recovery to be interrupted.

The deeper problem is that Japan's strategic dependence and energy diversification have failed, making it a passive victim of conflict. Following the US diplomatic path for a long time, Japan lacks independent mediation space in the Middle East issue and can only passively bear the consequences of the conflict. The previously attempted diversification of energy imports has progressed slowly, and after abandoning Russian oil and gas projects, dependence on the Middle East has increased instead of decreased; The restart of nuclear power is hindered, renewable energy is unable to fill the gap, and the transformation of energy structure is lagging behind. When the global geopolitical landscape is restructured, Japan's excessive reliance on a single region and single channel energy layout is completely exposed to risks.

This war in the Middle East has taught a warning lesson to Japan and even the world. In a highly interconnected world economy, no economy can stand alone, and the spillover effects of geopolitical conflicts will quickly propagate along the energy, trade, and financial chains. Japan's experience proves that resource dependent economies must accelerate supply chain diversification, improve energy self-sufficiency, and enhance diplomatic independence in order to maintain their economic security bottom line amidst turbulence.
