The cost of insuring exposure to Türkiye's sovereign debt fell Wednesday to its lowest level in about six-and-a-half months, as expectations of easing geopolitical risks in the Middle East and steps by the central bank on liquidity management supported investor sentiment.

Türkiye's five-year credit default swaps – a form of insurance for bondholders – fell to 217 basis points, a level not seen since Feb. 18, days before the U.S. and Israel launched the war against Iran. The premium had soared to above 320 basis points around early April.

Emerging-market risk premiums have generally declined as signs of a possible easing in tensions between the U.S. and Iran raised hopes for renewed diplomatic talks and a more lasting resolution to the conflict.

Reports that the U.S. government is preparing to return diplomats to some embassies evacuated during the war, along with comments from mediating countries that negotiations between the sides could resume, helped improve sentiment.

The developments also eased concerns over energy supplies, sending oil prices sharply lower. Brent crude futures for October delivery fell 3.9% to $88.60 a barrel, while the U.S. 10-year Treasury yield declined about seven basis points to 4.63%.
