Back
For several weeks, global markets allowed themselves to price in the comforting narrative of geopolitical de-escalation. The diplomatic dance in Switzerland and preliminary understandings over Persian Gulf maritime traffic had driven the crude oil price down from its recent peaks, briefly easing inflation concerns and convincing fixed-income markets that the worst of the energy shock was behind us. This week, however, served as a sharp, jarring reminder of how rapidly geopolitics can tear up market assumptions, forcing investors into an immediate inflation “wake-up call”.
The fragility of the diplomatic path was laid bare on Wednesday when United States (US) President Donald Trump declared that the interim peace agreement with Iran “is over”. The announcement, followed swiftly by renewed US strikes on strategic Iranian targets and subsequent military retaliation from Iran, instantly injected a heavy risk premium back into energy markets and reminded asset managers that supply-side inflation remains a clear and persistent danger.
The inflation wake-up call
The sudden re-escalation in the Gulf coincided with fresh evidence that inflation expectations are becoming uncomfortably sticky. The Federal Reserve (Fed) Bank of New York’s June Survey of Consumer Expectations, released this week, showed short-term US inflation expectation jumping to 4.2%, its highest level since late 2023. At the same time, expectations grew across financial markets that inflation in Europe and the UK will be noticeably higher a year from now, forcing traders to rapidly rethink how central banks will move interest rates.
For US Fed Chair Kevin Warsh and his counterparts at the European Central Bank (ECB) and Bank of England (BoE), the message is clear: central bank credibility hinges on maintaining an uncompromising stance against second-round price effects. With oil surging nearly 6% in a single session, bond markets quickly recalibrated to expect higher-for-longer policy rates, stripping away any lingering optimism for monetary easing in late 2026.
MARKET MOVES
Bonds
Sovereign bond markets experienced a sharp sell-off this week as inflation fears returned with vigour. The US 10-year Treasury yield climbed back towards 4.48%, while shorter-dated two-year yields jumped five basis points as traders increased bets on further Fed tightening under Fed Chair Warsh. This followed the Fed’s June meeting minutes, which signalled that several officials remain open to rate hikes if price pressures persist.
European debt yields rose sharply, led by short-duration bonds. Germany’s two-year bund yield was up 10 basis points in its biggest one-day jump in nearly a month, with 10-year bund yields edging up to 3.02%. Swap markets aggressively re-priced the ECB rate, now anticipating roughly 35 basis points of additional rate increases before year-end as war-driven energy costs threaten to push headline eurozone inflation back toward 4%.
UK 10-year gilt yields rose to 4.88%, with two-year yields matching European peers in a 10-basis-point upward surge. The BoE faces an intensifying stagflationary dilemma as cooling labour market data collides with renewed imported energy inflation.
Equities
Wall Street experienced a volatile, news-driven session on Thursday. The S&P 500 and Dow Jones Industrial Average surrendered early-week gains following the geopolitical headlines from Washington, as energy sector outperformance was overshadowed by broad-based selling in rate-sensitive tech and consumer discretionary names. Semiconductor stocks provided a minor buffer, supported by resilient demand forecasts.
European benchmarks traded lower, with the STOXX 50 falling 1.8% and the STOXX 600 shedding 1.5% for the week. Airlines, travel operators, and chemical manufacturers took the brunt of the equity drag as jet fuel and natural gas futures spiked, while European defence and oil majors like Shell and BP posted solid tactical gains.
The UK’s FTSE 100 edged down to 10,473, as gains in multinational oil producers and mining giants were offset by weakness in domestic retail and utility lines, which bowed under the weight of rising gilt yields and elevated borrowing costs.
Commodities
Brent crude staged a dramatic rally, surging over 6% on Wednesday to breach $79.40/barrel after touching multi-month lows of near $72/barrel earlier in the week. The sudden reversal came as President Trump declared the interim Iran deal over and restarted military strikes after renewed security risks in the Strait of Hormuz. These actions effectively restored the geopolitical risk premium that had unwound throughout late June.
Gold prices fell sharply, trading down to $4,070/ounce after reaching a two-week high earlier in the period. The metal succumbed to high real US yields, a rising greenback, and hawkish central bank expectations, which countered traditional safe-haven demand.
Industrial metals were mixed, with platinum slipping below $1,600/ounce and palladium easing to $1,222/ounce, while copper held firm near $6.07/pound on persistent long-term structural supply constraints.
Currencies
The US Dollar Index is trading firmly above 101.5, drawing a double tailwind from safe haven flows and rising US interest rate expectations following the NY Fed’s elevated consumer inflation survey print.
The euro has slipped further against the dollar, trading down to $1.162/€, as the threat of renewed stagflation across the bloc is weighing heavily on single-currency sentiment despite growing expectations of an ECB rate hike.
Sterling is fluctuating around $1.334/£, remaining under pressure as UK economic activity measures contracted while energy-driven input costs have surged.
