ABIDJAN- Ivory Coast plans to issue 135 billion CFA francs ($243 million) in domestic bonds to finance its infrastructure development, a lead manager of the auction said on Tuesday.

The auction includes 90 billion CFA francs in seven-year bond at a 5.8% interest rate, and a 45 billion CFA franc 10-year tranche at 5.9% coupon, according to the lead manager from NSIA bank.

The bonds, sold in units of 10,000 CFA francs, are being marketed to investors across West Africa's CFA currency zone from Sept. 17-30.

Ivory Coast, Francophone West Africa's largest economy and the world's biggest cocoa producer, has tapped international bond markets several times in recent years.
