Insight: Despite saying she would resist, Japanese Prime Minister Sanae Takaichi has succumbed to a temptation that routinely afflicts Japan’s leaders: launching a supplementary budget. She has more excuse than most, given soaring prices due to the Iran war — resource-poor Japan imports almost all its oil and nearly 90% of this comes through the Strait of Hormuz. Unsurprisingly, therefore, her JPY3 trillion ($19 billion) package is squarely focused on relieving energy costs. The centerpiece is a revival of government subsidies on electricity and gas bills from July to September, when air-conditioning demand peaks. The government will also replenish the contingency reserves it has been drawing on to cap retail gasoline prices. And it will establish a new dedicated reserve to fund further measures as the Middle East crisis continues.
Impact: While this package is undoubtedly popular, the question is how will it be financed? The prime minister promises there will be no need for additional bond issuance to pay for it due to stronger-than-expected tax revenues. That may be true mathematically, but with bond yields rising steadily (10-year JGBs have reached 2.7%), ratings agencies are warning that steeper financing costs could blow out the 2026/7 budget deficit beyond the expected 3.5% of GDP. The deeper problem is that fiscal expansion and monetary tightening are pulling in opposite directions: the Bank of Japan is considering raising its policy rate to 1% at its June meeting, which would further push up the servicing costs on Japan’s already heavy debt burden.
