CMLSML, true, but if you want to get a loan in 3 months and want to lock in a rate today, would you go for an FRA or for a swap? Even though from a profit/loss point of view they may be same, in reality, you will buy an FRA, not a swap. Another major diference is that FRAs are fixed in advance, paid in advance, while swaps are fixed in advance, paid in arrears.
