Global markets commenced September under selling pressure, largely due to the sharp increase in oil prices. This surge propelled bond yields higher and bolstered expectations for potential rate hikes by central banks within the month. The price of Brent crude soared past $92 per barrel amid ongoing disruptions in energy flows via the Strait of Hormuz, as per maritime security consultancy Marisks. This tension escalated following two anonymous attacks on oil supertankers in the region.
Impact on Global Bond Markets
The escalation in oil prices has heightened fears of inflationary pressure, leading to accelerated sales in global bond markets. The yield on the U.S. 10-year Treasury note reached its highest level since January 2025, while the 30-year yield remained above 5%. Such prolonged elevated long-term rates last occurred in 2006.
How Are Stock and Currency Markets Reacting?
Stock market appetite has weakened, partly due to pressures on tech stocks tied to artificial intelligence. Futures contracts on Nasdaq 100 and S&P 500 dipped by 1.1% and 0.6%, respectively. Concurrently, the dollar appreciated against major currencies, while gold prices hit a two-week low.
Japan’s bond market similarly experienced notable selling, lifting 10-year government bond yields to their highest this century. Following Treasury Secretary Scott Bessent’s call for monetary tightening from Japan’s central bank due to the weakening yen, market dynamics further shifted.
Furthering rate expectations in Europe, the Eurozone inflation was made evident. According to the European Union Statistics Office, consumer prices in August rose by an annual rate of 3.3%.
Iran’s recent tensions have increased energy costs, with projections of a 25-basis-point hike in policy rates by the European Central Bank (ECB) on September 10. Markets are largely pricing in this move.
- Italy saw inflation climb from 2.9% to 3.2%.
- Spain’s inflation reached 4.5%.
- Germany and France recorded faster price increases in August.
- ECB’s deposit rate currently stands at 2.25%.
Nonetheless, the slowdown in core inflation suggests rate hikes might not proceed as rapidly as anticipated. Analysts argue that persistent shocks in energy prices could revive discussions for another rate increase later in the year.
