Global bond yields have reached their highest levels since 2008, with the Bloomberg Global Treasury Index climbing to 3.68%. According to reports from Bloomberg, this represents the highest level since the 2008 global financial crisis, as the selloff occurs just days before rate decisions from the Federal Reserve, Bank of Japan, and Bank of England. The index, which tracks government debt from investment-grade countries, is heading for its biggest monthly drop since March, challenging hopes that the worst of this year's bond rout has passed. Euro zone and US bond yields recorded their largest monthly increase since March as Middle East conflict concerns renewed inflation fears, with traders pushing back interest rate cut expectations. As per Reuters, the selloff has been widespread across major markets, with US 30-year Treasury yields trading just below their highest level since 2007, while UK gilts have logged their longest streak of daily closes above 5% in almost two decades. Germany's 10-year yield has reached its highest point since 2011, and Japan's bond market has seen particularly dramatic movements, with its 40-year yield moving above 4% and its five-year yield hitting a record since the maturity launched in 2000. Australia now carries the highest benchmark yields in the developed world.
Market pricing now indicates that traders expect the European Central Bank's deposit rate to stand at 2.75% in early 2027, returning to levels last seen during the peak of tensions linked to the Iran conflict. According to Reuters, the ECB raised its key interest rate to 2.25% in June before keeping policy unchanged this month. Meanwhile, the Federal Reserve has maintained its current policy stance, with markets now expecting two rate hikes by June next year, including an almost fully priced increase in October. Germany's two-year government bond yield, which is highly sensitive to changes in monetary policy expectations, slipped 0.5 basis points on Friday to 2.76% but remained on track for a monthly increase of 22 basis points. In the United States, the two-year Treasury yield was steady at 4.23% and was set to finish July around 9 basis points higher. Germany's benchmark 10-year bond yield eased 1.5 basis points to 3.15% on Friday but remained on course for a monthly rise of 28 basis points, while the benchmark US 10-year Treasury yield also declined 1.5 basis points during the session to 4.65%, though it was still poised to end July roughly 22.5 basis points higher.
The Federal Reserve faces unprecedented challenges as the US government issues approximately $2 trillion in new Treasury bills and bonds annually, creating what economists describe as an unsustainable fiscal situation. As Debbie Hippensteel, senior portfolio manager at River Wealth Advisors, explains, "As the government continues to issue increasing amounts of debt to finance its spending, the supply of Treasury securities in the market grows. If investor demand does not keep pace with this increased supply, bond prices may decline, resulting in higher yields." This massive deficit issue, combined with strong employment data and inflation at 3.5% in June, creates a complex environment for the Fed's rate-setting committee. Even with inflation down from its 2022 record, the government's continued borrowing complicates monetary policy decisions, as higher yields can ripple through the economy by increasing borrowing costs for mortgages and auto loans for both consumers and businesses. If the Fed leaves rates unchanged, some initial US dollar selling would not be a surprise, given markets are pricing a meaningful chance of a hike.
While the Fed looms as the headline event, the Bank of Japan's policy decision less than 24 hours later could prove just as important for the near-term directional risk in USD/JPY. No change in the policy rate is expected, as the implied pricing above reveals, leaving the focus on the updated forecasts and Governor Kazuo Ueda's press conference. In April, the BOJ lowered its FY2026 growth estimate while revising its inflation outlook higher, lifting its core CPI forecast from 1.9% to 2.8%. It also maintained that risks to the inflation outlook remained skewed to the upside. Japan remains heavily reliant on imported energy, and the recent rebound in oil and LNG prices not only risks adding to domestic inflation pressures but also deteriorates Japan's terms of trade, creating another headwind for the yen. Before the policy decision, traders will receive the BOJ's preferred measure of underlying inflation when the Indicators for Core CPI report is released on Tuesday, providing a cleaner read on underlying price pressures.
Longer-dated government bonds underperformed during the month as investors focused on the potential consequences of a prolonged Middle East conflict. According to Reuters, markets increasingly factored in the likelihood of higher government spending, wider fiscal deficits and rising debt burdens, putting additional upward pressure on long-term borrowing costs. The selloff in bonds gathered pace through July as traders adopted a more hawkish outlook on monetary policy across both sides of the Atlantic. Japan's benchmark 10-year government bond yield held flat at 2.79% after the Bank of Japan left interest rates steady while signalling that further policy tightening remains possible. Improved energy supplies through key maritime routes helped calm markets despite limited progress in diplomatic talks between the United States and Iran, though the conflict's long-term economic impact remains a key concern for investors reassessing inflation expectations.
