Citable research brief

Core conclusion · Tlines extraction

MUFG argues the appeal of JGB yields to overseas real-money investors, key for stable absorption, has diminished. After deducting FX hedging costs, relative JGB attractiveness has fallen versus major government bonds, especially at 10-year maturities, because other major yields have risen faster; for full-maturity hedges, the narrowing negative USD/JPY basis has added to the drag. The report flags the FY27 JGB issuance plan and overseas RM trends as factors for stable absorption.

Key arguments

Appeal of JGB yields among overseas real-money investors, crucial for stable JGB absorption, has recently diminished.
After deducting FX hedging costs, relative JGB appeal has declined versus major government bonds, particularly 10-year maturities, for both short-term and full-maturity hedges.
The decline reflects other major government bond yields rising faster than JGB yields; for full-maturity hedges, the narrowing negative USD/JPY currency basis has also contributed.
Even versus UST, the appeal of JGB yields after currency hedging, especially 10-year, has declined; attention turns to the FY27 JGB issuance plan.

Key numbers

Short-term FX hedge tenor: 3, 6, or 12 months
JGB maturity example with full hedge: 10-year
Super-long JGB hedges by some South Korean RM investors: 5 to 10 years

Main risks

Rising yields on major government bonds outpace JGB yields, further eroding relative appeal after hedging.
Narrowing negative USD/JPY currency basis raises yen procurement costs for USD holders, reducing hedged JGB attractiveness.
Political risks in France have notably lifted French government bond yields, altering relative value comparisons.

Corresponding source evidence

1 As the BoJ’s holdings of JGBs continue to decline, and due in part to the impacts of various regulations, it is unlikely that domestic financial institutions will resume their previously active stance on JGB investment.
Overseas real money investors often use currency hedges when investing in JGBs, except in cases when they hold yen-denominated bonds.
Investors may use short-term hedges with tenors of three, six, or 12 months and roll them over, or hedge for the full maturity of the bond. · short-term
