Suppose that Company A needs a floating rate loan of RMB 6,543,800+million, and Company B needs a fixed rate loan of RMB 6,543,800+million.

When they are not interchangeable, a floats LIBOR+ 1% and b is fixed at 12%. The two companies will pay LIBOR+ 13% of the cost.

After the change, A floats LIBOR+2%, B is fixed at 10%, and the agency fee is 0. 1%. One * * is the cost of LIBOR+65,438+02.65,438+0%, and the two companies will make a profit of 0.9%. After equal share, each company lost 0.45% of the cost, and an average company lost 45,000 yuan.

Method 2: The difference of fixed interest rate is 12%- 10%=2%, and the difference of floating interest rate is 1%, so the two companies pay 0.9% less on average than before the swap.

Answer: LIBOR+2%-0.45% = LIBOR+1.55%.

b: 12%-0.45% = 1 1.55%
