Key facts
- Japan's long-term interest rates, specifically 10-year Japanese government bond yields, are nearing 3%.
- This level has not been seen since 1996.
- Prime Minister Takaichi Sanae's government plans to cut the consumption tax on food from 8% to 1% starting April 2027.
- This tax cut is expected to create a significant fiscal shortfall.
- Persistent inflation, exacerbated by a weakening yen and volatile crude oil prices, is also driving up rates.
- Rising rates are causing bond losses for Japan's credit unions (shinkin banks).
Japan's long-term interest rates are approaching 3% for the first time in three decades, a development driven by a combination of persistent inflation and market concerns over fiscal shortfalls stemming from Prime Minister Takaichi Sanae's proposed consumption tax cuts. The yields on 10-year Japanese government bonds (JGBs) hit a 30-year high of 2.930% on August 17, with some analysts predicting a breach of the 3% threshold by the end of August.
The government's plan to reduce the consumption tax on food from 8% to 1% starting in April 2027 is a primary driver of anxiety, as it is projected to create an annual funding gap of up to ¥5 trillion. While the government has stated it will review expenditures and revenue, market participants are closely monitoring how the fiscal shortfall will be addressed. The tax rate is slated to return to 8% in 2029, but political considerations surrounding an upcoming upper house election in 2028 could make a tax hike difficult, raising doubts about Japan's long-term fiscal health.
Inflation is another significant factor contributing to the rise in long-term rates. The yen's depreciation has helped push the corporate goods price index into the 5% to 7% range year-on-year since April. Should companies pass these increased costs to consumers, inflation is expected to accelerate. The Bank of Japan's cautious approach to rate hikes, including its decision to maintain its policy rate in July, has fueled concerns that it may not be effectively curbing inflation, thereby adding further upward pressure on long-term yields.
These rising interest rates are impacting Japan's financial institutions, particularly its credit unions, known as shinkin banks. The increased yields erode the value of their existing bond holdings, potentially affecting their lending capacity.
