Japan reverses BOJ independence bid as yen hovers near 162

Japan on Wednesday scrapped a proposed revision to its economic blueprint that would have limited the Bank of Japan's independence, a reversal that pushed the yen higher and stabilized JGB yields as traders reassessed political risk.

"The government's decision to walk back the language shows Tokyo recognizes the market consequences of undermining central bank credibility," said Tetsuji Okamoto, chief Japan economist at Mizuho Research Institute. "Any perceived erosion of BOJ autonomy would have complicated the normalization path significantly."

The yen strengthened 0.6 percent to 161.15 per dollar following the announcement, while the 10-year JGB yield eased 3 basis points to 1.42 percent. The currency had touched 162.84 last week, its weakest level since 1986, after reports emerged that the government was considering language that would give it greater oversight of the central bank's policy decisions. The dollar index held near 100.97 after suffering its biggest weekly decline since April following weaker-than-expected US payroll data.

The proposed revision had threatened to reopen a debate about central bank independence that Japan has largely avoided since the 1998 BOJ Law, which formally granted the bank operational autonomy. The last time political pressure on the BOJ reached comparable levels was in 2012-2013, when then-Prime Minister Shinzo Abe pushed for aggressive monetary easing, ultimately leading to the yield curve control framework that the bank spent the past two years unwinding.

Markets now price a 45 percent probability of a 25-basis-point rate hike at the BOJ's July 31 meeting, up from 32 percent before the blueprint controversy emerged, according to overnight index swap data. The current policy rate stands at 0.50 percent after the BOJ raised rates twice in 2025 — a 15-basis-point move in March followed by 10 basis points in October — ending eight years of negative rates.

For global bond investors, the episode highlights the fragility of Japan's policy credibility at a time when the country's ¥1.1 quadrillion ($6.8 trillion) government bond market is the world's third-largest. A loss of confidence in BOJ independence could have triggered a selloff in JGBs that would have rippled through global fixed-income markets, given Japanese institutional investors hold more than $3 trillion in foreign bonds.

The reversal also removes a potential headwind for the yen, which has lost more than 12 percent against the dollar over the past 12 months as the US-Japan interest rate differential widened to more than 400 basis points. Analysts at Goldman Sachs said in a note Wednesday that the policy clarity could support further yen strength toward 155 by year-end, though they cautioned that sustained gains depend on the BOJ delivering on its rate hike timetable.
