US
US Treasury yields rose sharply over the quarter as oil-driven inflation concerns and resilient data led the US Federal Reserve (Fed) to its first rate hike since 2023; the 10-year closed the quarter at 5.28% (its highest since 2007), and the 30-year at 5.63% (its highest since 2002). Renewed escalation in the US-Iran conflict in July sent Brent crude from around US$70 to over US$100 a barrel and lifted inflation expectations, despite a softer June CPI print. In tandem, heavy Treasury issuance and fiscal deficit concerns drove a sell-off in longer-dated bonds, which an expanded long-bond buyback programme only briefly steadied.
The Fed turned more hawkish as the quarter progressed: three members dissented in favour of a hike in July, and Chair Warsh signalled at Jackson Hole that further tightening may be needed, lifting front end yields. In September, the Federal Open Market Committee raised rates by 25bps to 3.75%-4.00% in a unanimous vote, alongside a more hawkish dot plot. Economic data remained strong, with August core CPI and payrolls both beating expectations and fuelling bets on a Q4 hike. Markets are pricing in three further hikes by mid-2027, despite a downward revision to inflation announced at the end of September.
Europe
European sovereign bond yields rose markedly over the quarter, driven by a renewed energy price shock, a hawkish European Central Bank (ECB) and rising political risk. The 10-year bund yield closed the quarter at 3.60%, its highest level since 2009. The escalation of the US-Iran conflict in July sent oil prices sharply higher, leaving energy-dependent Europe particularly exposed after a softer June inflation print had briefly eased concerns.
The ECB held rates at 2.25% in July but maintained a firmly hawkish tone, with Executive Board member Isabel Schnabel arguing in August that further tightening would be needed. In September, the ECB lifted the deposit rate by 25bps to 2.50%, warning of an extended period of inflation well above target and upgrading its growth forecasts. Resilient data, including a stronger-than-expected Q2 GDP print and a three-year high in the September composite PMI, reinforced expectations of a hike. Fiscal and political uncertainty added further pressure, with concerns over France’s fiscal deficit and its 2027 presidential election pushing the Franco-German 10-year spread to 127bps, its widest since the 2012 euro crisis. Markets ended the quarter pricing in three hikes by mid-2027.
UK
UK gilt yields rose across the curve over Q3, with the 10-year and 30-year touching multi-year highs in September. Tensions between the US and Iran escalated in July, pushing oil back above US$100 per barrel and fuelling a global bond sell-off, with long-dated gilts under further pressure from fiscal deficit and issuance concerns. Inflation reaccelerated, with CPI climbing from 2.6% to 3.1% over the quarter. The fiscal outlook remained in focus for investors as Andy Burnham succeeded Sir Keir Starmer as Prime Minister in July. The Bank of England (BoE) held rates at 3.75% at both its July and September meetings, although in September it signalled that inflation risks were skewed to the upside and monetary policy may have to tighten. Markets ended the quarter pricing in a likely rate hike in November.
Japan
Japanese government bond yields rose in Q3 on growing expectations of a Bank of Japan (BoJ) rate hike and the broader global bond sell-off, with the 2-year and 10-year yields ending the quarter at or near their highest levels since the mid-1990s. The Bank of Japan (BoJ) held rates in July before hiking by 25bps in September, taking the policy rate to 1.25%, its highest since 1995. However, the decision struck a more dovish tone than expected, with two dissents in favour of holding rates. Markets nonetheless continued to price further tightening, despite slower Q2 GDP growth, as rising energy costs and a weak yen raised inflation concerns. The yen was a key focus throughout the quarter, after coordinated intervention by Japan and the US lifted it from its weakest level in around four decades against the US dollar, before it drifted back to 157.
