Japan's government debt is about 230–240% of GDP, mostly held at home. From 2013 the Bank of Japan (BOJ) bought JGBs on a vast scale and came to own about half of them. From September 2016 it also capped the 10-year yield near 0%, a policy called yield-curve control (YCC), loosening the cap in steps before ending it in March 2024. As the BOJ raised rates, to 1.25% in September 2026, the 10-year yield passed 3% for the first time since 1996.
Why it matters
Higher JGB yields can pull Japanese money home from US and European bonds, nudging yields up worldwide, and they raise Japan's own interest bill.
Facts, rules and data
Ministry of Finance auction results and debt statistics, BOJ holdings data and policy statements, IMF fiscal reports, and market yield data reported by Reuters and Jiji Press.
Debates and risks
How high yields can rise before Japan's interest costs bite, and whether the BOJ would step back in to buy if trading turned disorderly.

▸Japanese government bonds (JGBs) after yield-curve control could shrink Japan's lead among Foreign holders of US Treasuries (TIC data): Japan, UK, ChinaMainstream view
The connection
Japan is the largest foreign holder of US Treasuries, over $1 trillion. Japanese insurers and pension funds compare yields after hedging dollars back to yen, which costs roughly the gap between US and Japanese short-term rates. With 10-year JGBs above 3% in 2026, a hedged Treasury can pay less, so higher JGB yields tempt money home.
When and why
Tokyo's life insurers such as Nippon Life, the giant pension fund GPIF and Japanese banks, as the BOJ raised rates in 2024–26.
How solid is the link?
Treasury TIC monthly holdings data, Japan's Ministry of Finance weekly portfolio-flow figures, and insurers' published investment plans show shifts as yields change.
Debates and risks
How fast Japanese money would actually come home; so far shifts have been gradual, and some analysts think a 'great repatriation' is overstated.
▸Japanese government bonds (JGBs) after yield-curve control were bought by the BOJ through Quantitative easing (QE): buying bonds to push down ratesFact, law or data
The connection
From April 2013 the BOJ's 'quantitative and qualitative easing' bought JGBs at up to about ¥80 trillion a year, aiming for 2% inflation, and its share of JGBs rose to around half. Since July 2024 it has cut purchases step by step, so private investors must absorb more bonds.
When and why
Tokyo; Governor Haruhiko Kuroda launched the program, and Kazuo Ueda began the taper.
How we know
BOJ policy statements and holdings data, and Ministry of Finance JGB statistics.
Debates and risks
How smoothly markets can absorb the bonds the BOJ no longer buys, especially long-dated ones.

The connection
From September 2016 the BOJ targeted a 10-year yield near 0%, promising to buy whatever bonds were needed to hold it there. It let the yield move in wider bands from 2018, loosening faster as inflation rose in 2022–23, then ended the policy in March 2024 with its first rate hike in 17 years.
When and why
Tokyo, September 21, 2016 to March 19, 2024.
How we know
BOJ policy statements and JGB yield records.
Debates and risks
How much the cap distorted Japan's bond market, and how long normal trading will take to return.
