BOJ board member Kazuyuki Masu has signalled that the central bank may need to raise rates quickly if inflation accelerates, given Japan's still-accommodative financial conditions, according to Reuters. In a closely watched speech ahead of the BOJ's September 16-17 meeting, Masu warned that broadening price pressures have pushed underlying inflation very close to the central bank's 2% target. He also said the BOJ should move real interest rates out of negative territory as soon as possible. Masu's comments add to a series of increasingly hawkish signals from BOJ policymakers, with markets now seeing a September hike as nearly certain. A recent Reuters poll of economists expects the BOJ to raise its policy rate to 1.25% next week, followed by another increase to 1.75% in the second quarter of 2027. According to The Economic Times, Masu did not provide specific guidance on the timing or pace of future rate increases, stating the BOJ would need to assess whether the economy was moving in line with its baseline outlook while monitoring risks from oil prices, artificial intelligence-related demand, and yen movements.
Japan's government bond yields experienced significant pressure on Friday as escalating Middle East tensions drove up oil prices and fueled global inflation concerns. The 10-year bond yield climbed 7.5 basis points to 2.985%, while the 20-year rate rose seven basis points to 3.82%, according to CNBC TV18. The selloff was part of a broader global bond market rout, with Australia's three-year yield jumping as much as 20 basis points to 5.05%, its highest level since 2011, and New Zealand's two-year yield climbing 24 basis points. The US bond-market selloff accelerated on Thursday as spiking oil prices fanned inflation fears and the Treasury Department bought fewer bonds than expected during its first expanded buyback operation. Benchmark Treasury yields are approaching the closely watched 5% level ahead of US inflation data that stands to determine expectations for a Federal Reserve interest-rate hike next week.
Japanese government bond yields rose as escalating tensions in the Middle East pushed oil prices higher, while hawkish comments from a Bank of Japan official strengthened expectations of further monetary policy tightening. The benchmark 10-year JGB yield climbed 7.5 basis points to 2.985%, while the two-year yield, which is particularly sensitive to monetary policy expectations, rose 1.5 basis points to 1.845%, according to Reuters. Rising oil prices added to pressure on Japanese bonds as Iran said on Wednesday that it had attacked 10 ships near the Strait of Hormuz after the United States sank five Iranian oil tankers, marking the biggest wave of attacks on shipping by both sides since the six-month-old war began. Brent crude rose above $100 a barrel following the escalation, marking its first move above that level since late July. According to The Economic Times, Masu noted that higher fuel and chemical prices resulting from the conflict involving Iran could raise transportation costs, combined with persistent food price increases, could make inflationary pressures more durable. Higher input costs could increasingly feed into consumer prices, with the BOJ due to release August wholesale inflation data on Friday.
For decades, Japan has been one of the world's biggest exporters of capital, with Japanese investors holding almost $5 trillion of overseas assets. As reported by Bloomberg, Japan is the largest foreign holder of US Treasuries with a $1.1 trillion stockpile. However, the calculus is now shifting as domestic yields become increasingly attractive compared to overseas returns. Deutsche Bank AG previously estimated that potential reallocation into Japanese assets could reach as much as $440 billion over the next several years in an upper-bound scenario involving pension funds, insurers and retail investors. A recent BCA Research client poll shows 44% favor locking in yields at current levels, while PIMCO's Lotfi Karoui notes that "balanced portfolios are back: higher bond yields are restoring fixed income's role as both a potential source of income and a powerful diversifier."
According to Shoki Omori, chief Japan fixed-incom strategist at Deutsche Bank, Japanese life insurers were essentially absent from foreign-bond selling this year through August, while banks were modest sellers and pension trusts continued to add overseas assets. However, investors have increasingly responded by reducing currency hedges, with Omori estimating the hedge ratio on new foreign-bond investment has fallen to roughly 40% this year from 62% in 2024. This leaves the relative appeal of overseas bonds increasingly dependent on yen outlook. The current environment shows the risk-reward balance for bond ownership becoming more compelling from both relative value and portfolio diversification perspectives.
As reported by Bloomberg, markets are underpricing the potential impact of Japanese capital repatriation on global bond markets. Ales Koutny, head of international rates at Vanguard Asset Management Ltd.'s active funds, noted that if domestic yields continue to rise, Japan may gradually retain more capital at home, affecting not only the yen and JGBs but also Treasury markets, European bond markets and broader global funding conditions. The yen's gains this month have made it the best-performing of the Group-of-10 currencies, with analysts seeing potential for further acceleration after it broke through the key 155-per-dollar level. Meanwhile, other Asian currencies are showing remarkable strength, with the South Korean won soaring 16% against the dollar over the last couple of months and trading at its strongest level in nearly two years.
