On Wednesday, July 8, the pricing focus in the European bond market quickly shifted from the "summer carry trade environment" to "energy shocks and inflation repricing." Following the US president's announcement of the end of the ceasefire with Iran, Brent crude oil prices surged by over 6%, breaking through $79 per barrel. Simultaneously, the risk of conflict in the Strait of Hormuz increased, prompting the market to reassess the impact of energy prices on inflation expectations, central bank policy, and term premiums.

The bond market reacted directly, with the yield on German 10-year government bonds rising 7 basis points to 3.07%, a near one-month high and marking its eighth consecutive trading day of increases. French financing costs rose to their highest level since 2009, the yield on UK 10-year government bonds rose 10 basis points to 4.95%, and the yield on US 10-year Treasury bonds rose 2 basis points to 4.57%. This is not a bond market adjustment in a single region, but rather the result of energy risks, fiscal risks, and central bank expectations collectively pushing up the global interest rate center.

The core trigger for this round of bond market decline was not simply geopolitical factors, but rather the repricing of the transmission path of oil prices to inflation expectations. After Brent crude oil broke through $79 per barrel, the market needed to reassess the secondary impact of transportation, chemicals, food delivery, corporate energy costs, and wage bargaining on service prices. The European economy is more sensitive to imported energy prices, hence the significant adjustments in German, French, Italian, and British bonds.

For traders, the key is not how much oil prices rise on a single day, but whether energy risks evolve from short-term disturbances into sustained inflationary pressures. If the conflict affects shipping risk premiums, even if oil prices don't continue to rise unilaterally, it will increase the right-tail risk of the inflation distribution. The bond market is therefore no longer just trading on expectations of an economic slowdown, but is beginning to re-embed the scenario of "inflation remaining high for a longer period." The head of interest rate strategy at BNP Paribas believes this demonstrates that central banks still need to remain highly cautious, and points out that if more evidence of a second round of inflationary effects emerges before September, the case for further action by the European Central Bank will strengthen.

The money market has already priced in a near 90% probability of another rate hike by the European Central Bank in September, fully factoring in another rate hike this year, and further reflecting the possibility of another rate increase around the middle of next year. This change indicates that the market's main theme has shifted from "the rate hike cycle is nearing its end" to "policy rates remaining high or even continuing to rise."

Internal statements within the European Central Bank (ECB) are also reinforcing this pricing. ECB Executive Board member Isabel Schnabel recently stated that supply chain pressures remain high. Some officials also believe that inflation has not fully subsided, and wage, food, and service costs are likely to remain a source of pressure in the coming months. For the bond market, the impact of such statements is to weaken the narrative of interest rate cuts while amplifying the correlation between short-term and medium-to-long-term yields. If the central bank is concerned about a second-round effect, front-end interest rates will be revised upwards more quickly; if the market worries about prolonged inflation volatility, the 10-year yield will also rise through the term premium.

French bonds underperformed German bonds primarily due to the combination of energy inflation shocks and domestic political uncertainty. French financing costs rose to their highest level since 2009, indicating that investors are demanding higher risk compensation. Within the Eurozone, German bonds typically serve as a core safe-haven asset and pricing anchor; a relative weakening of French bonds often signifies that the market is beginning to reassess fiscal path, election expectations, and policy continuity.

Italian bonds also fell, with the spread between Italian and German 10-year bond yields widening to 81 basis points, the highest since May. This magnitude alone does not yet indicate systemic pressure, but the direction warrants attention. When oil prices rise and the probability of a European Central Bank rate hike increases, the duration assets of highly indebted countries are more susceptible to a double squeeze: rising risk-free rates on one hand, and widening sovereign credit spreads on the other. If the market shifts from profiting from yield spreads to hedging against event risks, the volatility of foreign bonds will be even higher.

The yield on 10-year UK government bonds rose to 4.95%, an increase of 10 basis points, indicating that the UK market is more sensitive to inflation stickiness. Traders have fully priced in a 25 basis point rate hike by the Bank of England by November and have given it about a 35% probability of a second rate hike this year. The problem in the UK is that service inflation and wage costs are more constraining interest rate pricing; if energy prices rise again, the market will more quickly question the stability of the decline in inflation.

Some analysts believe that prior to this week, the market had already begun considering the summer environment and carry trade strategies, but changes in the Middle East situation are testing this prospect. This highlights the core contradiction in the current market: a low-volatility, interest rate spread-earning pricing environment requires a stable macroeconomic backdrop, while energy and conflict risks can rapidly increase volatility, causing the yield curve to shift back towards defensive repricing.
