Hormuz supply disruption reshapes economics for Dune Oil's Turkish oil block

The largest lipid proviso disruption successful recorded past is playing retired against an antithetic backdrop for a tiny Vancouver-based vigor company: a flagship exploration artifact successful southeastern Türkiye whose autarkic assets valuation was built connected lipid prices roughly 50% below wherever the marketplace is trading today. 

Dune Oil Corp (CSE:DUNE, OTCQB:TRLEF, FRA:Z620) holds a 29% moving involvement successful Block M47, located in the Cudi-Gabar province of southeastern Türkiye. The artifact targets 32.4° API airy oil, a premium-grade crude benchmarked to Brent. The institution is presently fulfilling earn-in obligations, with US$15 cardinal committed crossed 2026 and 2027 toward the M47 enactment program, including exploration drilling. 

The macroeconomic discourse has shifted substantially since the block's autarkic assets valuation was completed. That valuation utilized a near-term Brent terms presumption of US$63.68 per tube for 2026. Brent has since traded supra US$100 per tube pursuing the partial closure of the Strait of Hormuz, which Dune estimates has removed approximately 9.1 million barrels per time from planetary proviso -- a disruption the institution says exceeds anterior humanities shocks, including the Gulf War. 

The unrisked NPV-10 from the autarkic valuation stands astatine US$733.5 million, nett to Dune's working interest, astatine the base-case terms assumption. The grade to which sustained higher prices would amended that fig depends connected reservoir outcomes that remain unresolved up of drilling. 

Scott Lower, Dune's president, has pushed backmost connected the presumption that the existent proviso crunch is temporary. "The statement is inactive treating this arsenic a impermanent spike. We don't see it that way. A decennary of underinvestment doesn't unwind successful a quarter," helium said. 

The supply-side statement has immoderate grounding successful broader marketplace data. Global upstream concern contracted sharply done the 2015-2020 play and, portion it has partially recovered, has not returned to pre-downturn levels successful astir producing regions.  

The disruption carries circumstantial consequences for Türkiye, wherever the macroeconomic unit connected vigor imports provides a home discourse for M47's imaginable development. 

Türkiye imports betwixt 1 and 1.2 cardinal barrels of lipid per time portion producing approximately 130,000 to 140,000 barrels domestically. The state meets roughly two-thirds of its full vigor needs done imported fossil fuels and ranks 2nd among G20 nations successful vigor imports arsenic a stock of GDP, down South Korea. 

A June 2026 analysis by energy deliberation vessel Ember estimated that the Hormuz situation would adhd US$14 cardinal to Türkiye's energy import measure betwixt March and the extremity of 2026, a roughly 30% increase implicit the baseline yearly burden. Türkiye paid US$47 cardinal for nett vigor imports successful 2025, of which lipid accounted for astir 47%.
