ECB Day: What DAX investors need to know today

DAX Market Letter: ECB, oil and US inflation dominate trading

Thursday, September 10, 2026

DAX under pressure – focus on the ECB

The DAX is currently trading significantly below its record high of recent weeks. The decisive factor weighing on the index is no longer corporate earnings reports, but rather the combination of  rising oil prices, higher bond yields, and increasing inflationary pressure .

Brent crude has risen back above the  $100 per barrel mark  . At the same time, the yield on ten-year US Treasury bonds is near  4.85% . This is worsening the environment for European stocks.  

German inflation confirms increased price pressure

The German inflation data published today offers no initial relief.

Consumer prices rose by  2.9% in August compared to the previous year  , exactly in line with expectations.  

Furthermore, the ECB will decide on its future monetary policy today. The market expects an  interest rate hike of 25 basis points to 2.65% . However, the decisive factor will be less the interest rate hike itself than the subsequent communication from ECB President Christine Lagarde.  

What is crucial for the DAX

A  hawkish Lagarde  – that is, an indication of further interest rate hikes – would be negative for the DAX.

Conversely, a  wait-and-see approach  could trigger a recovery, especially if the ECB emphasizes that future decisions will depend on the data and the development of energy prices.

Oil price becomes the central risk

The rise of Brent crude above $100 is now a serious macroeconomic factor.

The conflict in the Middle East is straining energy supplies and leading to higher transport and production costs. At the same time, this is raising inflation expectations. Brent crude has risen above $100 for the first time since July.  

This creates an unfavorable cycle for the DAX:

Higher oil prices → higher inflation → less room for interest rate cuts → higher yields → lower stock valuations.

Highly valued growth and technology stocks are particularly vulnerable.

In contrast, energy companies and, to some extent, banks are the beneficiaries.

DAX stocks in focus

Yesterday's trading was characterized by widespread risk aversion.  Siemens,  with a decline of almost 3%, was among the weaker DAX stocks. Deutsche Börse, Airbus, and Symrise also suffered significant losses.  

Today, interest rate-sensitive stocks are likely to be in particular focus.

SAP:  The stock remains one of the most important drivers of the DAX. Rising yields are a short-term drag on its valuation.

Siemens:  Following Wednesday's significant decline, the stock is under technical pressure. Due to its high index weighting, this development is also relevant for the DAX.

Deutsche Bank / Commerzbank:  Higher interest rates can generally support interest income. The banking sector could therefore perform relatively better than highly valued technology stocks.

Rheinmetall:  Geopolitical tensions remain a structural driver of the share price, while at the same time the stock is particularly vulnerable to profit-taking after the strong long-term rally.

US PPI this afternoon

The next big impetus will come from the USA.

The US Producer Price Index for August will be released at  2:30 PM CEST  . A year-on-year increase in the overall PPI rate of  4.7% to approximately 5.2% is currently expected ; the monthly forecast is for a rise of around  +0.2% .  

This is currently the most important short-term US catalyst.

Three possible reactions

PPI significantly higher than expected:
US yields rise, expectations for interest rate cuts/raises shift further towards a more restrictive Fed. Negative for the Nasdaq and DAX.

PPI roughly in consensus:
The market is likely to focus more on the ECB press conference and tomorrow's US CPI.

PPI significantly lower:
Relief in inflation expectations, falling yields and potential rebound in technology stocks.

Tomorrow's  US CPI  is even more important, however, because it directly influences Fed expectations. Markets currently see an increased probability of a Fed interest rate hike at the meeting on September 15th/16th.  

Trading plan for the DAX

 

After reaching a record high, the DAX is now in a clear  risk-off phase .

Three areas are crucial today:

1. Oil:  If Brent remains above $100, inflationary pressure will persist.

2. Yields:  A further increase in the US 10Y yield above the 4.85% range would be an additional warning signal.

3. ECB:  Lagarde's press conference is likely to determine the direction of the European interest rate market.

Conclusion

The short-term bias remains  bearish to neutral . The DAX continues to have fundamental support from solid corporate profits and the structural strength of major German companies. However, the short-term macroeconomic environment has clearly deteriorated.

Today, the decisive trigger is not the record high, but the market's reaction to the ECB, oil, and US PPI.

A decline in oil prices and falling yields could quickly trigger a technical rebound. However, if oil remains above $100 and yields stay high, the pressure on the DAX is likely to persist.
