Cement Al-Yamamah has just entered into a two-year floating-for-fixed swap contract, where payments are made every six months. The 6-month LIBOR is 4.31%. The 6 to 12 months forward LIBOR rate is 5.59% and the 12 to 18 month forward LIBOR rate is 8.27. The two-year swap rate is 6.6%. If the OIS rate is 3.5% and the term structure of the OIS rate is flat, what is the 18 to 24 month Forward LIBOR rate? All rates are semi- annually compounded, except for the OIS, which is continuously compounded. (Round to the closest hundredths. Rates should be in percentage form. E.g. 9.99%)
