Afghanistan's Deputy Prime Minister for Economic Affairs Mullah Abdul Ghani Baradar Akhund called for an agreement on gas pricing under the TAPI project. Baradar called on Afghanistan and Turkmenistan to reach an agreement on gas pricing and revise the pricing formula to limit the impact of severe fluctuations in European markets on gas prices. The European market, however, has increasingly shifted toward hub-based pricing, with the Netherlands' Title Transfer Facility (TTF) becoming a key benchmark. This means that the TAPI price does not necessarily have to track a single exchange benchmark and can instead incorporate several market indicators, coefficients and price-review periods. Baradar's reference to European markets appear to be relevant because Europe's gas prices have become more sensitive to global LNG markets following the decline in Russian pipeline supplies.
