Recommendations for energy-importing economies, with a Türkiye focus, on aligning temporary price instruments with monetary policy after the 2026 oil shock
ABSTRACT
In the 2026 energy shock, governments suppressed pump and utility prices with stock releases, tax cuts and regulated caps while central banks raised or held rates under tightening bias. This brief argues that the conflict between the two arms lies in timing: the temporary instruments defer the first-round price effect, and their published repayment, expiry and reset schedules hand central banks a known inflation path for late 2026 and 2027. Comparing the US exchange release, EU storage flexibilities, the Ofgem cap and Türkiye’s move from eşel mobil to a scheduled diesel excise tax with the Fed, ECB, BoE and CBRT decisions of September 2026, it recommends four measures to the Turkish Treasury, the CBRT and their counterparts.
1. Why the current mix sends contradictory signals
On 11 March the United States contributed 172.2 mb to the IEA members’ 426 mb collective release (International Energy Agency [IEA], 2026), and on 5 March Türkiye introduced eşel mobil for road fuels (PwC Türkiye, 2026). Monetary policy followed in the opposite direction: the Fed raised the federal funds target range to 3.75–4.00% on 16 September (Federal Open Market Committee [FOMC], 2026) and the ECB lifted its deposit rate to 2.50% on 10 September (European Central Bank [ECB], 2026). “Policy mix” here means the fiscal, executive and monetary instruments applied simultaneously to one external shock; “executive instruments” are tools usable without legislation or the central bank: stock releases, excise changes by decree and regulated caps.
The two arms can be complements. Bernanke, Gertler and Watson (1997) argue that a large share of the real cost of oil shocks comes from the central bank’s systematic tightening response. Kilian and Zhou (2022) estimate that post-2020 oil price increases raised US headline inflation and, through gasoline prices, households’ one-year inflation expectations, with small effects on core inflation and long-run expectations. If expectations track the pump price, holding the pump price down also holds expectations down and reduces the tightening needed. The complementarity turns into conflict on the date the instrument is withdrawn and the price jumps back.
The 2026 record shows that conflict building in four economies. The US exchange release moved 17.5 mb out of the Strategic Petroleum Reserve between the weeks of 20 March and 24 April, leaving 397.9 mb, on condition that the barrels be returned with additional barrels within a year (Cyprus Shipping News, 2026); that design creates purchase demand in 2027, when central bank projections expect disinflation. The release also targeted crude, while price pressure sat in products: in August gasoline rose 27.4% year on year and 3.9% month on month, accounting for more than a third of the monthly CPI increase, while core CPI stood at 2.4% (U.S. Bureau of Labor Statistics, 2026). The European Commission’s call of 23 March to use the Gas Storage Regulation’s flexibilities on fill targets, deadlines and injection timing (European Commission, 2026) cut volumes bought at high prices but thinned the winter buffer, deferring price risk to the heating season. In the United Kingdom, the Bank of England held Bank Rate at 3.75% by 6–3 on 17 September; wholesale gas prices had risen 78% since the July Report, Ofgem set the October–December cap at £1,723, the cap was expected to rise markedly in the first quarter of 2027, and inflation was projected to peak a little above 4% in that quarter from 3.1% in August (Bank of England, 2026). On this brief’s reading, the quarterly cap passes wholesale prices through with a lag and moves the peak into 2027; the dissenting member Megan Greene argued that waiting for firm evidence of second-round effects would leave policy behind.
Türkiye shows the same timing structure in its sharpest form. Under Presidential Decree 10995, eşel mobil absorbed 75% of any rise in international prices or the exchange rate through the special consumption tax (ÖTV) and raised the tax by the same proportion when prices fell (PwC Türkiye, 2026). On 13 August diesel ÖTV was set to zero and placed on a schedule of 3 TL in September, 6 TL in October, 9 TL in November, 12 TL in December and 13.9006 TL on 1 January 2027 (GZT, 2026). The schedule therefore writes a 3 TL monthly administered increase into the diesel price through December, and a further 1.9006 TL in January, independently of Brent. The CBRT held its policy rate at 37% on 10 September and said it would tighten in the event of a marked and persistent deterioration in the inflation outlook (Capital, 2026). Household inflation expectations had risen to 45.6% (Dünya, 2026). The conditional hold is coherent so long as the scheduled increase is not counted as deterioration; if the same increase lifts expectations, the condition triggers itself.
2. Recommendation 1: Publish one exit calendar for every temporary fuel instrument
Addressee: Ministry of Treasury and Finance. The diesel schedule is public; the status of eşel mobil for gasoline and LPG after 30 September could not be verified. The ministry should publish the post-September regime for all fuels in the same calendar format and transmit it to the CBRT ahead of the 22 October Monetary Policy Committee meeting (Uzmanpara, 2026). Rationale: a central bank can price a known path, not an undeclared one. Trade-off: a published calendar removes the option of quietly extending relief. Success indicator: a single official table covering every fuel through January 2027.
3. Recommendation 2: Separate scheduled administered increases from “deterioration”
Addressee: CBRT. The bank should state in its next decision text whether the pre-announced ÖTV steps fall inside or outside its tightening condition, and name the expectations measure that would trigger action. Rationale: Kilian and Zhou’s (2022) expectations channel means that the scheduled steps matter for policy only to the extent that they move expectations; a household expectation of 45.6% against market participants’ 29.4% for year-end 2026 (Dünya, 2026) shows which measure is under strain. Sequencing: at the 22 October meeting, before the October and November steps accumulate. Trade-off: precision reduces the discretion that a vague condition provides. Success indicator: household expectations falling from 45.6% while the schedule proceeds.
4. Recommendation 3: Time repayments and refills outside the projected disinflation window
Addressees: energy ministries using exchange-type releases or storage flexibility, notably the US Department of Energy and EU member states. Repayment of exchanged barrels and the refill of relaxed storage targets should be scheduled and announced with volumes, and spread so that deferred demand does not concentrate in the first half of 2027. Rationale: the one-year repayment clause and the thinner winter gas buffer both convert 2026 relief into 2027 demand. Sequencing: announce before end-2026. Trade-off: spreading repayment lengthens the period of reduced emergency cover. Success indicator: central bank projections that list the repayment and refill volumes explicitly.
5. Recommendation 4: Condition central bank projections on the exit calendars
Addressees: the CBRT, Fed, ECB and BoE. Each projection round should state which exit calendars it incorporates, as the BoE minutes did for the Ofgem cap. Rationale: Bernanke, Gertler and Watson (1997) locate much of the real cost in the policy response; a central bank that sees the deferred price path early can respond more gradually than one surprised by it. Sequencing: from the next projection round. Trade-off: publishing the conditioning invites pressure on governments to change the calendars. Success indicator: smaller upside forecast errors for the first half of 2027.
6. Implementation risks
The recommendations depend on governments keeping their calendars: an extension of diesel relief under political pressure would invalidate the path the CBRT priced. In Türkiye a jointly published path could also be read as central bank endorsement of tax policy. If Brent falls, the ÖTV schedule becomes a tax recapture that limits pass-through of lower prices and protects revenue, which weakens the inflation case for coordination.
7. Outlook: Türkiye, Saudi Arabia and the World
In Türkiye, October to January will test the weight of the fiscal calendar on monetary policy. Diesel ÖTV rises to 6 TL in October and 13.9006 TL on 1 January 2027 (GZT, 2026). If Brent stays high, the scheduled increase adds to the international price rise and the CBRT’s condition is tested in practice at the 22 October and 10 December meetings (Uzmanpara, 2026); if Brent falls, the schedule limits the decline at the pump and protects revenue.
In Saudi Arabia, the mix runs the other way. In the second quarter of 2026 subsidies rose 73% and financing costs 41% year on year, and the entire first-half deficit of SAR160bn was debt-financed (Arab News, 2026); the source does not say how much of the subsidy bill concerns domestic energy prices. If the Fed’s tightening path continues, that financing becomes dearer, which makes the global interest rate a 2027 fiscal variable for Riyadh alongside oil revenue.
Globally, the next threshold is the FOMC meeting of 27–28 October (Board of Governors of the Federal Reserve System, 2026). The return of exchanged SPR barrels and the Ofgem cap reset in the first quarter of 2027 indicate that deferred price pressure will reach central banks again in the first half of 2027. If these calendars stay outside projections, 2027 disinflation forecasts carry upside risk.
8. Conclusion
The 2026 conflict between price-suppressing instruments and rate increases is a conflict of timing, and the timing is already published. The US exchange release generates repayment demand in 2027, the Ofgem cap produces an inflation peak in the first quarter of 2027, and Türkiye’s ÖTV schedule writes monthly administered increases into the diesel price until January 2027. The September 2026 central bank decisions can be read as attempts to price that deferred pressure now. Coherence depends on whether exit calendars are designed and communicated together with the monetary policy calendar, which Türkiye’s Treasury and the CBRT can do before the October and December meetings.
