• U.S. Treasury yields rose after the Treasury Department announced a $6 billion buyback of longer-dated debt, with the 30-year yield reaching 5.30% and the Dow Jones Industrial Average falling roughly 440 points.
• Oil prices remained elevated as U.S.-Iran hostilities and tanker attacks in the Gulf kept supply risks in focus, with WTI settling just above $94 a barrel and Brent breaking above $100.
• Bank of Japan tightening expectations strengthened after board member Kazuyuki Masu said rates were likely to keep rising under still-accommodative financial conditions, while markets increasingly priced a September move to 1.25%.
• The yen extended its advance as USD/JPY fell below 153 at points during the session, with the move linked to growing conviction around a broader Bank of Japan tightening cycle.
• The euro held above 1.16 ahead of the European Central Bank policy decision, with markets fully pricing a 25-basis-point increase that would take the deposit rate to 2.50%.
• U.S. inflation data remained central to Federal Reserve expectations, with market pricing still showing elevated odds of a September rate increase ahead of producer and consumer price releases.
• OPEC output was estimated to have fallen by 900,000 barrels per day in August to 19.91 million barrels per day, led by a 1.12 million barrel-per-day drop in Saudi production amid regional escalation.

Macroeconomics & Central Banks

Bank of Japan Tightening Expectations Firm as Policymakers Signal Scope for More Rate Increases

Bank of Japan board member Kazuyuki Masu said the central bank expects to continue raising interest rates given still-accommodative financial conditions, reinforcing market expectations that policy normalisation has further to run. Separate market surveys and strategist commentary pointed to a 25-basis-point increase at the September 17-18 meeting, which would lift the policy rate from 1.00% to 1.25%.

A move to 1.25% would take Japanese rates to their highest level in nearly 31 years, according to the reporting during the session. Reuters polling cited expectations for a further rise to 1.75% in the second quarter of 2027, while analysts pointed to firm GDP, wage and inflation data as support for near-term tightening. Final second-quarter GDP was reported at an annualised 1.4% quarter-on-quarter, or 0.9% year-on-year, while July wage growth was cited at 4.7% for total wages and 4.1% for base wages.

At the same time, commentary in the reporting highlighted that officials remain sensitive to market stability. Analysts said an outsized 50-basis-point move or back-to-back hikes was not their base case, noting that large policy surprises could trigger renewed carry-trade unwinding and broader market volatility.

Yen Strengthens as Markets Price Broader Bank of Japan Normalisation

The yen extended its gains during the reporting window as investors increased bets on a sustained Bank of Japan tightening cycle and reduced expectations that currency support would rely solely on official intervention. USD/JPY fell below 153 during the session, touching 152.88 before consolidating around 153.26, while other reports put the pair near 153.40 and down about 0.39% on the day.

The move was linked to rising Japanese government bond yields, stronger wage trends and resilient domestic growth, all of which were cited as undermining the yen’s long-standing role as a low-yield funding currency. Market commentary also referenced remarks from U.S. Treasury Secretary Scott Bessent warning against testing Japanese authorities on intervention, while analysts said a more durable yen move would depend on the Bank of Japan establishing a tightening cycle that extends beyond September.

Reporting also noted that Japanese investors’ shift toward domestic bonds has so far been gradual rather than abrupt, but higher JGB yields are encouraging reinvestment into higher-coupon local paper. That dynamic has added to expectations that policy tightening in 2026 and 2027 could further support domestic bond demand and yen stability.

ECB Decision in Focus as Markets Price 25-Basis-Point Rate Increase

The euro held above 1.16 ahead of the European Central Bank policy decision, with markets fully pricing a 25-basis-point increase that would take the deposit rate to 2.50%. EUR/USD traded around 1.1635 to 1.1647 during the reporting window, supported in part by broader U.S. dollar softness.

Reporting on the ECB outlook pointed to steady euro-area growth and renewed inflation concerns tied to higher energy prices and Middle East tensions. Commentary cited euro-area GDP growth excluding Ireland at around 0.3% quarter-on-quarter since the start of 2024, broadly in line with estimates of potential growth, while some strategists argued that risks around the policy path remained tilted toward further tightening rather than cuts.

The session also kept attention on U.S. inflation data, with producer and consumer price releases seen as key inputs for next week’s Federal Reserve decision. Market pricing referenced in the reporting showed elevated odds of a Fed rate increase, leaving both the ECB decision and U.S. inflation prints central to the near-term global rates backdrop.

Government Debt & Markets

U.S. Treasury Buyback Announcement Pushes Long-Dated Yields Higher

U.S. Treasury yields rose after the Treasury Department announced plans to buy back $6 billion of longer-term government debt, three times the size of its usual operation. The move failed to calm the long end of the market, with the 30-year Treasury yield reaching 5.30% during the session.

The market reaction spilled into equities, where the Dow Jones Industrial Average slid roughly 440 points and traded below 52,400. Reporting described the Treasury bid as falling short, underscoring continued pressure on long-dated borrowing costs even after the larger buyback announcement.

Energy & Geopolitics

Oil Holds Near Recent Highs as Gulf Hostilities Keep Supply Risks Elevated

Oil prices remained elevated as military escalation involving the United States and Iran, tanker attacks and threats to shipping in the Persian Gulf kept supply risks at the centre of the market. WTI traded around $93.85 to $94.00 during the reporting window after rising more than 2% and reaching its strongest level since May 22, while Brent broke above $100 a barrel for the first time since late July.

Reporting cited additional U.S. strikes on Iranian oil tankers near Kharg Island, Iranian missile launches toward Jordan and warnings that vessels in the Gulf could be targeted. Other reports described the week as marked by attacks on tankers and a broader deterioration in regional security conditions, with crude maintaining a strong risk premium even when intraday price moves turned mixed.

Supply-side pressures were reinforced by lower OPEC production. A Bloomberg survey cited in the reporting estimated OPEC output fell by 900,000 barrels per day in August to 19.91 million barrels per day, driven by a 1.12 million barrel-per-day drop in Saudi production amid the escalation. The combination of disrupted regional flows, weaker output and persistent shipping risks kept attention fixed on physical supply conditions.
