Key takeaway

Negative quarter-hours arrived while the daily mean held near EUR 90, a within-day shape problem.

German day-ahead power printed minus EUR 15.01/MWh in its lowest quarter-hour on Saturday 25 July, and France minus EUR 11.32, the first sub-zero prints of this window after a hard zero floor earlier in the week, when German day-ahead was still clearing near EUR 100 on an already negative spark . 1

The daily mean tells a different story from the extremes. Germany still averaged EUR 89.90/MWh that day, because 18.86 GW of solar met a Saturday load of 44.4 GW. 2 Midday oversupply drove a handful of quarter-hours below zero while the evening ramp kept the average up. Anyone hedged on daily averages saw an unremarkable summer weekend; anyone dispatching against quarter-hourly prices saw hours they had to pay to generate into.

A secondary tracker put Saturday's German day-ahead at EUR 85.11/MWh. 3 This desk's EUR 89.90 averages every quarter-hourly print of that day, published by SMARD under Bundesnetzagentur licence. The two figures measure different things and both can be right, which is worth knowing before anyone reconciles a position against the wrong series.

Deep Analysis

In plain English

For a few fifteen-minute periods on Saturday, both Germany and France were briefly paid to take electricity rather than paying for it, the first time either market had gone below zero in this run. That sounds dramatic, but it only happened for a handful of quarter-hours; across the whole day, average prices in both countries stayed well above zero. It happens because some power stations, like nuclear reactors, cannot simply switch off for fifteen minutes when there is a brief surplus, so the price goes negative instead to persuade someone to use the extra power.

Deep Analysis
Root Causes

A negative quarter-hour does not mean supply exceeded demand across the whole day, only that inflexible generation, must-run thermal plant, nuclear baseload and subsidised renewables that keep running regardless of price, could not be curtailed fast enough to avoid a brief oversupply window; Germany's EUR 89.90 daily mean on the same day shows the problem was confined to specific quarter-hours rather than the day as a whole.

The structural driver is the mismatch between fifteen-minute price granularity and generation that cannot ramp on that timescale, which is why the two negative quarter-hours arrived on the softest-demand day of the week rather than the highest-wind day.

What could happen next?
  • Meaning

    The first sub-zero quarter-hours of the window are a granular oversupply signal, not evidence that either market's daily price level has broken down.

Causes and effects
This Event
Germany and France print sub-zero hours
Negative quarter-hours alongside a daily mean near EUR 90 make this a shape problem inside the day, not a collapse in the level.
Led to
Same wind, two prices: solar sets gap
The first sub-zero quarter-hour prices of 25 July contrast with the EUR 187.30 night-time peak of 31 July on similar wind levels, isolating solar as the swing variable.
Occurred 31 Jul 2026

Different Perspectives
Shipping and insurance underwriters
Shipping and insurance underwriters
Kpler counted five Hormuz transits on 16 August against 31 the previous weekend, while Windward logged four vessels going AIS-dark for up to a month; underwriters price both the attacks and a sanctions register that names their counterparties in unreadable scanned images. Two trackers now measure only the ships that consent to be seen.
China
China
China sits at the end of the payment chain the 14 August designation targets: Iran's shadow banking network exists to convert sanctioned oil sales, much of it to Chinese refiners, into usable funds. Beijing has previously refused to recognise OFAC's jurisdiction over its own entities buying Iranian crude, leaving this designation to test compliance rather than change trade.
Qatar
Qatar
Qatar's foreign ministry denied on 16 August holding any Iranian pilots alive, contradicting Iranian General Mohammad Bagherzadeh's claim that Doha holds three Su-24 aircrew, and said it had recovered only one set of remains. Qatar carries Iran's messages to Washington, and this is a public break with Tehran over a fact only one aircrew inquiry can settle.
Oman
Oman
Oman's shipping-map talks, covering monitoring, environment and maritime services, were publicly decoupled from any Hormuz reopening by Iran's own foreign minister on 17 August. Muscat's mediation channel keeps functioning on the narrow file it was given, while the political decision it hoped to unlock stays with Iran's security council.
Saudi Arabia
Saudi Arabia
Saudi Arabia separately called the recurrence of tanker attacks on Emirati shipping a dangerous escalation, breaking from the UAE's repeated formula. Riyadh speaking in its own name over an attack on another state's vessels signals it reads the pattern differently from Abu Dhabi's flat statements.
United Arab Emirates
United Arab Emirates
The UAE foreign ministry condemned a third ADNOC-linked tanker attack on 15 August in language identical, word for word, to its statement the day before. Three consecutive strikes on Emirati shipping have not moved Abu Dhabi's public wording by a single adjective.
