MUFG: Rising household JGB appetite may shift medium-term yen outlook
USD/JPY climbed back toward 160 after a stronger-than-expected US inflation reading, keeping intervention risk in focus. MUFG's Derek Halpenny argues that growing household demand for Japanese government bonds could eventually favor the yen.

MUFG’s Derek Halpenny observed that the yen weakened sharply following the newest US inflation figures, driving USD/JPY back close to the 160 mark, a level above which Japanese authorities become far more likely to step into the currency market.
Even with that slide, he pointed out that sentiment around Japanese government bonds (JGBs) is improving. He tied this to a more engaged Bank of Japan (BoJ) and a general market consensus that the central bank sits only one or two hikes away from reaching its neutral interest rate.
Halpenny also noted chatter that Japanese authorities could soon introduce measures to encourage households to buy JGBs directly, such as letting individual bond holdings qualify for tax-free NISA accounts or shielding them from inheritance tax.
In his view, these developments are early hints that domestic buying of JGBs may be gathering strength, and that further confirmation would reinforce the argument for a genuine break from years of persistent yen depreciation. Given that intervention risk should limit further upside in USD/JPY, alongside firmer confidence in the BoJ’s policy path, he judged that the balance of risks now leans toward yen strength over the medium term.
Why it matters for markets: A policy shift that lifts domestic appetite for JGBs could bolster the yen by keeping more domestic savings onshore and strengthening expectations of continued BoJ tightening — both factors that would feed through to USD/JPY. The 160 level remains a closely watched trigger point for possible intervention.
