Bond yields climbed after a political battle that broke out over the country's new constitution last month threatened to undermine the government's efforts to prop up the economy and public finances.
"Rates are climbing due to the elevated economic and political risk," said a Cairo-based fixed income manager.
Standard & Poors' cut Egypt's long-term credit rating on Monday and said another cut was possible if the political turmoil continued.
The yield on the five-year bonds, which mature on Nov. 13, 2017, ranged from to 13.90 percent to 14.37 percent compared to 14.00 to 14.25 percent at an auction on Dec. 10.
The ministry of finance, which normally provides average yields, did not release a figure on Monday. The average yield on five-year bonds at a Dec. 10 auction was 14.163 percent.
Settlement for the bonds will take place on Nov. 13.
The central bank sells the bonds on behalf of the finance ministry.
