Both the forward and reverse rates increase, but the forward rate increases more than the reverse rate. O Both the forward and reverse rates increase, but the reverse rate increases more than the forward rate. O The forward rate increases while the reverse rate decreases. O The reverse rate increases while the forward rate does not change.
