Turkey-Iran Gas Deal Expires Amid Geopolitical Shifts

The 25-year natural gas export contract between Iran and Turkey has quietly expired without any official announcements from either nation.

The agreement, implemented in 2001, was a cornerstone of economic cooperation between the two neighbors, piping approximately 9 to 10 billion cubic meters (bcm) of Iranian natural gas to Turkey annually. However, neither Iranian nor Turkish officials have provided a clear explanation regarding the contract's ultimate fate.

Turkish media outlets note that Iran ranked fourth as a supplier of natural gas to Turkey in 2022, accounting for approximately 7.7 to 7.8 billion cubic meters, representing nearly 13 percent of Turkey's total gas imports. While Iran's market share has declined compared with previous years, it remains a critical component of Turkey's energy mix.

Turkey's strategy has been to diversify its energy supplies, expanding its liquefied natural gas (LNG) import infrastructure and ramping up domestic production at the Sakarya gas field in the Black Sea. However, any future agreement between Tehran and Ankara will likely be shorter in duration, more flexible in its volume commitments, and specifically structured to navigate updated sanctions regimes and financial clearance mechanisms.
