Yen Financing Costs Surge Tenfold, Japanese Companies Consider Asset Sales to Cope
nashnova research
Yen bond issuance costs have risen roughly tenfold since the Bank of Japan introduced negative rates a decade ago, with 10-year JGB yields hitting 3% for the first time in nearly thirty years; companies are now weighing asset sales and offshore borrowing to manage the interest burden, and whether profit growth can offset refinancing pressure will shape Japan's capital-spending trajectory.
How much have borrowing costs risen?
Japan's 10-year government bond yield hit 3% this week — the first time in nearly thirty years.
Average yen bond issuance costs have climbed roughly tenfold from when the BOJ introduced negative rates in 2016. This means → debt taken on at near-zero cost now faces an interest bill several times larger upon refinancing.
Toyota Motor and Tohoku Electric told Bloomberg that refinancing yen bonds maturing within the next two years would raise their annual interest expenses by more than 30%.
How are companies responding?
Bloomberg surveyed 30 Japanese non-financial companies; 14 responded. Several said they are considering selling strategic shareholdings and other assets to offset rising interest costs.
Mobile carrier KDDI called asset sales to cut debt a potential option. Chugoku Electric Power said higher rates may accelerate its disposal of assets and cross-held shares.
In plain terms = the "idle assets" and cross-shareholdings accumulated during the low-rate era have become a war chest companies can liquidate to service debt.
Could refinancing pressure slow investment?
Bloomberg data show the 30 surveyed companies have a combined ¥6.74 trillion in bonds maturing between September 2026 and August 2028.
Mitsubishi UFJ researcher Shumpei Fujita noted that rising rates may already be dragging on capital investment — sectors such as fabricated metals, electricity, and natural gas have seen capex growth decelerate.
Daiwa House Industry said rate increases could affect property prices, forcing it to revisit the hurdle rate — the minimum return an investment must earn to be worth pursuing — on real-estate projects.
Can offshore borrowing cut the bill?
Japanese issuers have sold over $110 billion in dollar- and euro-denominated bonds so far this year, making them the single largest issuer group in Asia-Pacific.
This means → when yen debt is too expensive, companies tap dollar and euro markets for cheaper funding. Swapped back into yen, the all-in cost is sometimes equal to or lower than domestic borrowing.
JERA said it will use interest-rate swaps — instruments that lock floating rates into fixed ones — and broaden its investor base; Tokyo Electric Power Grid said it has pre-arranged financing over the past six months.
What does this mean for global markets?
The BOJ's policy stance has become a topic in U.S.–Japan bilateral talks. This reflects the fact that Japan's rate normalization is no longer a domestic affair — it is a variable that moves global capital flows.
Japanese corporate profits remain in an expansion cycle, and AI infrastructure spending continues. Whether profit growth can fully offset refinancing pressure is the key variable for sustaining Japan's capex momentum.
Put simply = if interest costs rise faster than earnings, companies will cut investment; if profits from AI and other new ventures are thick enough, the interest burden can be absorbed.
