Session report, Friday 18 September 2026. Thursday’s close confirmed; Friday figures are intraday.
Highlights
- Frankfurt’s DAX 40 rose roughly 0.7%, or 197 points, on Thursday to close just above 25,700, its highest level in more than a week.
- Friday opened at 25,681.60, broadly flat against the previous close.
- Today is quadruple witching day, when index futures, index options, single stock futures and single stock options all expire together, typically lifting volume and amplifying late session moves.
- The rally was driven by falling oil prices and easing global bond yields after the US Federal Reserve raised rates by 25 basis points.

- Technology lagged, with Infineon among the heaviest fallers at roughly 2%.

- The index sits around 3% below its record high of 26,618.74, reached on 28 August 2026.
Frankfurt goes into the weekend on a stronger footing than it looked mid week, but the session itself carries a technical distortion worth understanding before reading too much into the close.
Where the DAX Stands
Thursday delivered the week’s decisive move. The DAX added roughly 197 points, a gain of about 0.7%, to finish just above 25,700. That followed Wednesday’s close at 25,538, itself a rise of 135 points or 0.53%. Two consecutive advances took the index to its best level in more than a week.
Friday opened at 25,681.60, essentially unchanged. For context, the index remains roughly 3% below the record high of 26,618.74 set on 28 August 2026, within a 52 week range running from 21,863.81 to 26,618.74.
Why today’s close deserves an asterisk
Today is the third Friday of the quarter, which in European and US markets means quadruple witching: index futures, index options, single stock futures and single stock options all expire on the same day.
The practical effect is mechanical rather than fundamental. Volumes swell as positions are rolled or closed, market makers unwind hedges, and index tracking funds adjust for any quarterly constituent changes taking effect. The final hour typically sees the sharpest activity.
This matters for interpretation. A large move on a witching day frequently reflects expiry flow rather than a change in sentiment about German corporate earnings or the European economy. Traders who read Friday’s close as a directional signal without accounting for expiry are reading noise as information.
What Drove the Move
| Factor | Effect on the DAX | Detail |
|---|---|---|
| Fed rate decision | Supportive | A 25 basis point increase was widely anticipated, and delivery without a surge in long dated yields removed uncertainty |
| Chair Kevin Warsh’s tone | Supportive | Firm on inflation while avoiding a renewed rise in long term yields, a combination investors read as credible |
| Falling oil prices | Supportive | Continued declines eased the inflation outlook across the euro area |
| Global bond yields | Supportive | Easing yields lift equity valuations, particularly for longer duration sectors |
| Autos sector | Positive contributor | BMW around 2%, Daimler Truck 1.8%, Volkswagen roughly 1.1% on Thursday |
| Industrials and energy | Positive contributor | Siemens Energy gained between 1.7% and 2% depending on the measurement window |
| Technology sector | Negative contributor | Infineon fell roughly 2%, the heaviest single drag |
| Other decliners | Negative contributor | Symrise down 0.77% and Brenntag down 0.49% |
| EU trade tension | Overhang | Trump threatened tariffs or trade restrictions over Canada’s proposed associate membership of the bloc |
| Quadruple witching | Technical | Expiry flows distort volume and late session price action |
The Fed did the heavy lifting
The catalyst came from Washington rather than Frankfurt. A 25 basis point increase from the Federal Reserve might ordinarily weigh on equities, but the move was fully expected and, crucially, did not trigger a fresh rise in long dated yields. Chair Kevin Warsh held a firm line on inflation while avoiding the bond market reaction that had unsettled investors earlier in the month.
For a market like Germany’s, where industrial and export heavy constituents are sensitive to global financing conditions, the absence of a yield shock mattered more than the rate move itself.
Oil kept falling
Crude extended its decline, easing the inflation picture across the euro area. This cuts differently in Frankfurt than in London: the DAX carries far less direct energy exposure than the FTSE, so cheaper oil is close to unambiguously positive for German industrials and consumer names. Current levels are tracked on the Brent crude oil price page.
Autos led, technology lagged
BMW, Daimler Truck and Volkswagen all advanced, reflecting the sensitivity of German carmakers to financing conditions and to the oil price through input and logistics costs. Siemens Energy continued a strong run, having also featured among Wednesday’s biggest gainers.
Infineon went the other way, falling around 2% and making technology the weakest corner of the index. That divergence between cyclicals and semiconductors has been a recurring feature of recent sessions.
The trade threat sits in the background
Trump’s threat of serious tariffs or trade restrictions on the EU, prompted by Ursula von der Leyen’s proposal to make Canada the bloc’s first associate member, did not derail Thursday’s rally but represents an unresolved risk. Germany’s export weighted index is structurally more exposed to transatlantic trade policy than most European benchmarks.
Reading Frankfurt Against London
The two benchmarks diverged this week for structural reasons rather than sentiment. The DAX gained on falling oil because it has limited energy weight and substantial industrial exposure. The FTSE 100 was dragged lower on Friday partly because Shell and BP carry heavy index weight, so cheaper crude hits it directly.
The lesson generalises: when a macro variable moves, the direction of each national benchmark depends far more on sector composition than on the health of that country’s economy.

- Friday opened at 25,681.60, close to flat, with the session subject to quadruple witching distortions.
- The Federal Reserve’s 25 basis point increase, delivered without a spike in long dated yields, was the principal driver.
- Falling oil prices and easing global bond yields supported valuations across German cyclicals.
- Autos and industrials led, with BMW, Daimler Truck and Siemens Energy among the strongest names.
- Technology lagged, with Infineon the heaviest single drag at roughly 2%.
- EU trade tension over Canada’s proposed associate membership remains an unresolved overhang.
- The index trades around 3% below its record high of 26,618.74 set on 28 August 2026.
Frequently Asked Questions
What is quadruple witching and why does it matter for the DAX?
Quadruple witching is the simultaneous expiry of index futures, index options, single stock futures and single stock options, which happens on the third Friday of March, June, September and December. Volumes rise sharply as positions are rolled or closed and market makers unwind hedges, with the effect concentrated in the final hour of trading. For the DAX it means Friday’s price action may reflect expiry mechanics rather than any change in the fundamental outlook, so single day moves on these dates should be treated cautiously.
Why did the DAX rise when the Federal Reserve raised interest rates?
Because the increase was fully anticipated and, more importantly, did not trigger a renewed rise in long dated bond yields. Markets had feared a repeat of the earlier bond rout. Chair Kevin Warsh managed to maintain a firm anti inflation stance without unsettling the long end of the curve, and that removal of uncertainty was worth more to equity investors than the rate move cost them.
Is the DAX a price index or a total return index?
The headline DAX is a performance index, meaning dividends are reinvested rather than stripped out. This is unusual among major benchmarks and it matters for comparisons. Measuring the DAX against price return indices such as the FTSE 100 or the CAC 40 flatters German performance over long periods, because the DAX figure includes dividend income that the others exclude. A price return version of the DAX exists for like for like comparison.
