CAIRO- The average yield on Egypt's three- and seven-year treasury bonds fell at an auction on Monday, central bank data showed, continuing a recent trend.

The average yield on the three-year bonds fell to 15.097 percent on Monday from 15.504 percent at the last auction, on Sept. 18. Seven-year bond yields fell to 15.220 percent from 15.500 percent.

Appetite for Egypt's domestic debt has increased since the central bank floated the pound currency and lifted key interest rates by 700 basis points since November.

Average yields have come down in recent weeks as foreign currency liquidity has improved.
