European natural gas prices extended their two-week rally on Monday, with the front-month TTF benchmark at the Amsterdam exchange rising to €69.22 per megawatt hour (MWh), up more than 4% from Friday’s close and just below the March peak of €70.85/MWh set during the escalation of the Iran conflict.
The commodity has gained roughly one-third over the past two weeks, driven by sustained concerns over Middle East supply risks. U.S. officials have intensified rhetoric targeting Iran and its trading partners, with Treasury Secretary Scott Bessent warning in a Financial Times op-ed that supporters of Tehran should "consider the consequences" of their involvement. A speech scheduled for later Monday is expected to outline further measures, though the path to effective pressure remains unclear given China’s role as a key Iranian trade partner.
Market participants cite persistent risks to energy flows from the Persian Gulf as a primary driver of the upward trend. Analysts also point to growing unease over winter supply readiness in industrialized economies, particularly as European storage levels continue to decline.
Gas Infrastructure Europe (GIE) data shows the bloc’s aggregate storage level fell to 61.68% on August 22, down from 62.32% the previous day and well below the 75%+ level recorded a year earlier. Germany’s reserves have deteriorated more sharply, dropping to 50.71% from over 68% in the same period last year.
The combination of elevated geopolitical risks and falling inventories underscores the fragility of Europe’s energy security heading into the heating season.
