Reuters calculations on ENTSOG data put TurkStream average April flow at 41 mcm/day, only 1.7% below April 2025. The week-old 25% drop framing collapses on inspection.

Key takeaway

TurkStream April at 41 mcm/day is only 1.7% below April 2025; the March 2026 surge was the anomaly.

Reuters calculations on ENTSOG (European Network of Transmission System Operators for Gas) data, relayed via Baird Maritime on Monday 4 May, put TurkStream average April flow at 41 mcm/day (million cubic metres per day) 1. The figure broadly corroborates the 40.3 mcm/day EADaily had reported on 27 April , but the framing collapses on inspection. The drop is -25.5% MoM against March 2026 and only -1.7% YoY against April 2025, 1.23 bcm versus 1.25 bcm.

March was the anomaly, not April. The March 2026 surge was front-loading ahead of the Hormuz price spike , the same pattern Bruegel identified in EU LNG terminal data for the same month . Reuters attributes the April reversion to demand and pricing effects rather than pipeline disruption. Gazprom has not published its own monthly statistics since January 2023, which is why a single-source EADaily figure was able to dominate the narrative for a week before a wire-service cross-check landed.

Two positioning points follow. TurkStream is not a new disruption stacked onto the supply book; at 1.23 bcm against 1.25 bcm a year earlier, the YoY shortfall sits well inside seasonal noise. When the only number available comes from one outlet without a wire-service cross-check, the structural reading is doing more work than the data supports, as the EADaily 25% framing showed across the prior week. Lowdown flagged that print as single-source on 27 April ; the corrective Reuters/ENTSOG frame has now landed.

Deep Analysis

In plain English

TurkStream is a gas pipeline that runs under the Black Sea from Russia to Turkey, then branches north into southeastern Europe, supplying Hungary, Serbia, Bulgaria and Slovakia. A news outlet reported in late April that the pipeline's gas flow had dropped by 25% compared to the previous month, which sounded alarming. But Reuters checked the same data from the EU's official pipeline-flow network and found the drop was only 1.7% compared to the same month last year. The big month-on-month fall was because March had been unusually high, not because April was unusually low.

Deep Analysis
Root Causes

The narrative dominance of the EADaily 25% framing for a full week before the Reuters correction reflects a structural data quality gap: Gazprom stopped publishing monthly statistics in January 2023, removing the primary cross-check source for TurkStream throughput figures. ENTSOG publishes daily flow nominations, but interpreting those nominations as monthly volumes requires a calculation step that commodity desks perform and regional news outlets typically do not.

The gap creates a window in which a tier-3 outlet with Gazprom-adjacent sources can set the narrative frame, and the corrective wire-service read takes days to propagate across the regional media ecosystem in Hungary, Slovakia and Serbia, precisely the markets most exposed to TurkStream volume shifts.

What could happen next?
  • Precedent

    The week-long EADaily narrative dominance before the Reuters/ENTSOG correction illustrates how data gaps from Gazprom's January 2023 reporting halt create recurring mispricing windows that wire-service corrections cannot close in real time.

  • Risk

    Q2 LNG contingency tenders filed by Bulgarian and Serbian buyers in response to the EADaily framing may not be cancelled even after the corrective read, adding speculative LNG demand to an already tight Atlantic cargo market.

Equinor
Equinor
Equinor stacked a 13-16 June planned maintenance window on Hammerfest LNG directly atop the unresolved compressor fault running since 22 April, creating two simultaneous live stoppages at 4.3 mtpa capacity for the first time. The 10 July return target carries overrun risk: the same compressor class slipped 24 days in the 2025 maintenance cycle.

EDF's fleet repriced French July contracts roughly 10% in two days on cooling-water curtailment risk, flipping the FR-DE spread to France EUR 1.6 above Germany after a EUR 96.20 record in the other direction a week earlier. Industrial buyers long France against short Germany face EUR 97.7/MWh of spread swing in seven calendar days.
Hungary and Slovakia supply-security ministries

Hungary's Tisza government has reframed Russian gas dependency as a systemic risk, removing Budapest as a co-plaintiff in the CJEU challenge; MVM's 3.5 bcm long-term TurkStream contract remains exempt to September 2027, so Budapest's near-term supply is intact. Slovakia under Fico presses its QMV challenge alone and faces a 3-4 bcm/year short-term supply gap with no contracted LNG alternative.

At JKM-TTF of USD 5.26/MMBtu, every uncommitted Atlantic cargo loading in late June routes east; the arb sits roughly twice the OIES-assessed diversion threshold of USD 2.50-3.00/MMBtu after freight. European storage terminals are the losing bid in the cargo auction until TTF recovers or JKM eases.
European Commission / ACER
European Commission / ACER
The Commission structured Regulation 2026/261 as a QMV trade measure to resist Article 194 unanimity challenges; the six-origin prior-authorisation waiver acknowledges that LNG capacity cannot substitute pipeline gas within the legislative window. ACER's cross-border enforcement powers activate in H2 2026, but jurisdiction over the Kipi entry point is legally contested.

Capacity planners at Uniper and RWE face the StromVKG Wirtschaftsausschuss scrutiny as the decisive near-term fork: if the Greens' hydrogen-conversion amendment passes, the September 2026 auction becomes unbiddable on technology risk grounds and the capacity-payment fix delays into winter. Plants that have run at -EUR 44 spark spread for weeks cannot commercially sustain extended shut-in.
