Key Highlights
- European equity markets declined on Monday following military confrontations between the United States and Iran in the Strait of Hormuz that sent Brent crude oil beyond $90 per barrel
- Tehran is preparing to establish a restricted military zone in the vicinity of Hormuz following weekend strikes by U.S. military forces on three Iranian tankers
- Market participants anticipate a 25 basis point rate increase from the European Central Bank this Thursday, with Deutsche Bank projecting an additional hike in December
- Swiss pharmaceutical giant Novartis saw shares decline more than 3% following disappointing results from a high-profile cholesterol drug trial
- Upcoming U.S. inflation data this week will be critical in determining whether the Federal Reserve proceeds with a rate increase at its September policy meeting
European stocks began the week under pressure on Monday as escalating military tensions between Washington and Tehran roiled global energy markets while investors braced for an imminent rate decision from the European Central Bank.
The broad STOXX 600 index fluctuated between modest gains and declines, trading close to lows not seen in several weeks. Germany’s DAX index retreated 0.3% while France’s CAC 40 similarly posted losses.

Switzerland’s primary index tumbled 1.2%, weighed down predominantly by Novartis, which plunged over 3% after its experimental cholesterol medication produced disappointing results in a highly anticipated clinical trial.
Energy Prices Rally on Hormuz Disruption Concerns
Brent crude oil advanced more than $1 per barrel during Monday trading, building on a nearly 10% rally from the previous week to trade decisively above the $90 threshold.
The price surge followed weekend military strikes by U.S. forces that disabled three Iranian oil tankers. The Pentagon characterized the strikes as a response to an Islamic Revolutionary Guard Corps ballistic missile assault on two U.S. Navy vessels operating in the area.
Tehran has responded by announcing intentions to establish a restricted military zone outside the Strait of Hormuz in the coming days.
Approximately 20% of the world’s seaborne petroleum and natural gas transits through the Strait of Hormuz. Any significant disruption to shipping in this critical waterway could trigger elevated energy prices and contribute to inflationary pressures globally.
European energy sector stocks provided one of the few positive notes, advancing 1.2% alongside rising crude prices.
Central Bank Rate Increase Anticipated This Thursday
The European Central Bank is broadly expected to increase its benchmark interest rate by 25 basis points when policymakers convene on Thursday. The anticipated move reflects Eurozone inflation climbing to 3.3% in August, with energy expenses surging 14.3%.
Deutsche Bank analysts now project the ECB will implement the September rate adjustment followed by another quarter-point increase in December. Market pricing also reflects expectations for at least one additional rate hike in 2027.
Persistent rate increase expectations have maintained German 10-year government bond yields near multi-year peaks, creating headwinds for interest rate-sensitive sectors including real estate and construction.
Germany’s political landscape contributed additional uncertainty. The far-right AfD party secured 44% of votes in Saxony-Anhalt state elections during the weekend, representing a setback for Chancellor Friedrich Merz, although the party did not achieve an absolute majority.
Italy’s Lottomatica defied the broader market trend, climbing 6.8% after releasing specifics regarding how its planned merger with Spain’s Cirsa will expand its digital operations. Cirsa shares gained 7%.
Investor confidence throughout the Eurozone reached its strongest level in more than four years during September, according to survey data published Monday.
Market attention now shifts to U.S. Consumer Price Index figures scheduled for release later this week. An elevated inflation reading could solidify expectations for a Federal Reserve rate hike at its September 15-16 policy meeting, potentially intensifying pressure on global stock markets.
