DAX Surges to Record 26,319; Markets Eye Inflation Data and Iran

DAX Closes at 26,319 as Multiple Tailwinds Converge

German equities surged in the past week, sending the DAX to a record close of 26,319.45 points – a gain of 2.7%. The rally was powered by a confluence of factors: hope that the Strait of Hormuz might reopen, falling crude oil prices, and better-than-feared German economic data. The tech-heavy TecDAX outperformed with a 6.3% weekly jump, while the mid-cap MDAX lagged, rising only 1.3%.

Index heavyweights were pivotal. SAP extended its recovery with an 11.9% weekly gain, the single largest contributor to the DAX’s advance. Deutsche Telekom added 7.8% following a robust quarterly report, and chemical distributor Brenntag climbed 4.8% after raising its annual guidance. By contrast, Zalando shares slumped 12.7% after its quarterly numbers disappointed, and insurance giants Allianz and Munich Re saw muted reactions to their reports. The positive tone spilled into US markets: the Nasdaq Composite gained 5.2%, the S&P 500 rose 3.6%, and the Dow added 2.9%.

This week, however, many analysts expect a more cautious mood. The initial optimism that the US and Iran could de-escalate has faded after President Trump indicated that Iran’s conditions for reopening the Strait of Hormuz are unacceptable. Persistent geopolitical uncertainty, combined with a packed economic calendar – including inflation readings from Germany and the US – suggests the rally may pause for reflection.

What’s Driving – and Threatening – the Rally

The Hormuz Narrative and Oil Prices

Last week’s gains were partly built on the assumption that the Strait of Hormuz – a critical oil transit chokepoint – might reopen soon, easing supply fears and lowering crude prices. Those hopes have dimmed. US President Donald Trump signalled over the weekend that Iran’s conditions are not acceptable, making a quick resolution unlikely. For markets, this means the ‘war risk premium’ in oil and the associated inflation anxiety remain firmly in play. A renewed spike in oil prices would quickly unnerve equity investors.

US Jobs Data Dampens Rate Fears – for Now

Friday’s much weaker-than-expected US employment report was a gift for risk assets. It reduced expectations that the Federal Reserve would raise rates as soon as September, driving bond yields lower – the yield on the 10-year German Bund fell 7 basis points to 3.13%. Lower yields improve the relative attractiveness of equities, especially technology and growth names. However, this narrative faces an immediate test with the US consumer price index release on Wednesday. A hot CPI reading could swiftly resurrect rate hike fears and reverse the bond market’s friendly stance.

Tech Rebound and Index Concentration

The TecDAX’s 6.3% leap underscores a broader rebound in chip and AI-related stocks internationally. SAP’s 11.9% surge was the standout, underlining the outsized influence of a single stock on the DAX. Deutsche Telekom’s post-earnings rally added further momentum. Meanwhile, the MDAX’s lagging performance highlights a market that is rewarding large-cap, internationally exposed names over smaller German industrial firms – a pattern that has persisted for weeks.

What the Earnings and Data Flow Mean

Zalando’s 12.7% drop after disappointing numbers is a reminder that earnings season will punish high-expectation names that stumble. This week, several DAX companies report: Brenntag, E.ON, Hannover Re on Wednesday, and RWE on Thursday. In the US, Cisco’s report on Wednesday stands out as the last major tech name of this reporting wave. On the data front, the harmonised German CPI and the US CPI on Wednesday, followed by the US producer price index on Thursday and the University of Michigan consumer sentiment survey on Friday, will all be scrutinised for clues on the Fed’s path. The Michigan reading will be especially telling: if consumers’ inflation expectations jump again, the rate-hike argument strengthens sharply.

Key Dates to Watch This Trading Week

• Wednesday’s US CPI (12 August): The headline and core inflation numbers will be the week’s most market-moving data point. A print above consensus could rapidly undo the rate-hope rally. German harmonised CPI on the same day will provide a European mirror.
• Michigan Consumer Sentiment (Friday, 14 August): Focus on the 1-year and 5-year inflation expectation components. A rise here would signal that households see price pressures as sticky, potentially forcing the Fed’s hand even if other data softens.
• Oil price signals: With the Strait of Hormuz staying shut, any military or diplomatic development in the Iran conflict will directly move crude prices. Watch for comments from US or Iranian officials that could change the supply outlook.
• Key German earnings: Brenntag (Wednesday) – confirmation of raised guidance could extend its rally. E.ON (Wednesday) and RWE (Thursday) will give insights into the energy sector’s current profitability. Hannover Re (Wednesday) may echo the subdued insurance sector sentiment seen at Allianz and Munich Re.
• Cisco Systems (Wednesday): As the last major US tech giant to report in this cycle, Cisco’s numbers and forward guidance will set the tone for networking and IT infrastructure stocks.
• Germany-US interest rate differential: If German inflation (Wednesday) comes in higher than expected while US data disappoints, the spread could narrow further, potentially strengthening the euro and weighing on German exporter stocks.
