ISTANBUL- Turkey's Treasury and Finance Ministry said on Monday it had mandated Citi, JP Morgan and Societe Generale for a dollar-denominated dual-tranche bond issuance.

The two tranches consisted of the re-opening of a bond maturing Oct. 2028, as well as the sale of a new bond maturing 2033, it said.

Bankers said the initial yield expectation for the 2028 eurobond was around 5.95% and around 6.75% for the 2033 bond.
