Japan Faces Growing Fiscal Strain as BOJ Ends Stimulus

Japan faces growing fiscal challenges as BOJ ends stimulus, forcing the government to rethink funding for large spending packages and tackle rising debt costs.



The Bank of Japan’s (BOJ) decision to scale back its decade-long radical stimulus program is intensifying pressure on the Japanese government to rethink its approach to funding massive spending packages, posing a significant challenge for Prime Minister Shigeru Ishiba’s administration.

Ishiba’s government recently unveiled a fiscal package worth 13.9 trillion yen ($92 billion), aimed at cushioning the impact of rising living costs on Japanese households. To fund this, the government is set to finalize its supplementary budget by Friday. However, the package is not without complications. The ruling coalition under Ishiba is reportedly bowing to opposition demands for permanent tax cuts, a move that analysts warn could result in a revenue shortfall of up to 4 trillion yen next year.

This fiscal dilemma comes amid the BOJ’s gradual exit from its ultra-loose monetary policy. For years, Japan relied on low interest rates and the BOJ’s extensive bond-buying program to finance large-scale spending. But the central bank’s decision to abandon its yield curve control policy in March, coupled with plans to reduce bond purchases and raise short-term interest rates, now threatens to increase Japan’s debt-servicing costs. As borrowing becomes more expensive, the government faces growing financial strain, further complicating its fiscal decisions.

Japan’s public debt, the largest among advanced economies and nearly double the size of its GDP, is a constant concern. Debt-servicing costs are to consume a staggering 27 trillion yen – or 24% of this year’s total budget – an unsustainable figure for the long term. While the BOJ’s yield cap had helped keep borrowing costs low in the past, any spike in bond yields could push these costs even higher, further straining government finances.

Japan Faces Growing Fiscal Strain as BOJ Ends Stimulus

Despite Japan’s growing fiscal challenges, the government continues to increase spending, in stark contrast to many advanced nations that have scaled back pandemic-era stimulus. The Bank of Japan (BOJ) kept borrowing costs low for years, enabling the government to fund large deficits. However, with the BOJ stepping back from its stimulus measures, the government now faces the difficult task of financing its expanding debt while responding to political demands for more fiscal stimulus.

Japan’s debt is enormous, estimated at 1,100 trillion yen, the largest among developed countries. Government bond (JGB) issuance for the current fiscal year is projected at 182 trillion yen, down 6% from last year. However, this may rise due to the new 13.9 trillion yen fiscal package. Analysts expect bond issuance to remain steady or increase in the next fiscal year, depending on the size of the discussed permanent tax breaks.

Additionally, the finance ministry faces a challenge with dwindling demand for super-long-term JGBs from life insurers. This places more pressure on private banks to purchase government debt, but private bank holdings of JGBs have dropped dramatically, from 41% in 2013 to just 14% today, after years of BOJ bond-buying. Stricter capital regulations also discourage banks from ramping up purchases.

With debt-servicing costs rising and higher interest rates on the horizon, Japan’s government must navigate the tension between fiscal stimulus and fiscal sustainability. The coming months will be crucial in shaping the country’s financial future as it grapples with these mounting challenges.
