Germany's benchmark 10-year government bond yield rose 3 basis points on Thursday to 3.135%, marking its strongest level since May 20. The note has gained 10 basis points over the course of this week and climbed 28 basis points during July.
Traders cited heightened tensions from intensified fighting in the Gulf as a driver of higher euro zone yields this week. Those developments pushed benchmark European gas prices to a 15-week high on Wednesday before stabilizing on Thursday. Brent crude oil priced slightly lower on the day at $84.90 a barrel.
Market participants are weighing the risk that rising oil and gas costs could feed into inflationary pressures. That, in turn, could prompt the European Central Bank to adopt a more aggressive stance on interest rates than currently anticipated, a dynamic that market participants say may also weigh on longer-term economic growth prospects.
Markets are currently assigning roughly a 90% probability to an ECB rate increase by the central bank's September meeting. If enacted, that move would represent the ECB's second rate hike this year following a lift in June. Market pricing also indicates a strong possibility of an additional, third rate adjustment before the end of the year.
Across the curve, short-dated, rate-sensitive German debt tracked the benchmark move on Thursday. The 2-year German yield rose 3 basis points to 2.75%, mirroring the shift seen in the 10-year maturity.
Meanwhile, movement in U.S. Treasury yields was comparatively restrained. Cooler inflation data limited volatility in U.S. government debt, contributing to a narrowing in the spread between German and U.S. 10-year borrowing costs to its narrowest point in a month.
Market context and implications
This week’s price action reflects market attention to geopolitical developments in the Gulf and their potential to affect energy prices and central bank policy. Investors and policymakers will likely continue to monitor energy benchmarks and incoming economic data closely as they reassess rate expectations and the outlook for growth.
