Europe Markets in Uncertainty: Oil Prices and Yields Persist as Key Pressures

On September 29, 2026, European stock indices displayed mixed performance as oil prices stayed elevated above $100 per barrel due to ongoing Middle East tensions.

The Paris CAC 40 managed a slight gain of 0.02% at opening, while the Frankfurt DAX fell 0.09%, the London FTSE rose 0.05%, and the Amsterdam Stoxx 600 increased by 0.03%.

Investor confidence remains shaken by the prolonged impasse over the Middle Eastern conflict, which keeps oil prices well above $100 per barrel and pushes central banks to raise interest rates to combat inflation.

Iranian Foreign Minister Abbas Araqchi reported that Tehran expects a US response within weeks to its proposal for a ceasefire and reopening of the Ormuz Strait, according to official Iranian media.

Negotiations between the US and Iran continue, with President Donald Trump having rejected the Iranian offer on Saturday but stating he expected further discussions later in the week.

Meanwhile, sovereign debt markets hit new daily highs driven by inflation fears and high public debt levels. The US 10-year Treasury yield reached its highest level since May 2004, while the 10-year German Bund closed around its June 2009 peak at 5.27%. The German 10-year yield has also held near its multi-year high.

Angus Hui of Fullerton Fund Management in Singapore noted, "We enter a new environment" where interest costs represent an increasing share of public budgets in many developed markets, making it unlikely that bond yields will return to previous low levels.

Central banks have adopted a firmer stance on inflation risks, with Australia's Reserve Bank raising its policy rate to 4.60%—its fourth increase this year—as inflation proved too high and they remain ready to raise rates further if needed.

ECB President Christine Lagarde emphasized that a measured response remains appropriate to contain price increases across the bloc, noting that annual inflation so far has not yet triggered secondary effects.

Beyond monetary policy, investors remain wary of AI-driven growth: Anthropic's IPO prospectus shows the company betting heavily on AI transforming the global economy more profoundly than industrialization, electricity, and the internet, though at enormous cost. OpenAI has suspended the launch of its next-generation model GPT-6.1 Astra after internal testing revealed security and alignment issues, confirming Monday that the developer behind ChatGPT halted the rollout.
