I feel it is over the top complaint from the businessman, he should have asked more questions when entering into the agreement. I mean you don't sign anything if you don't know what will happen if one or another event occurs. It is very easy to make basic calculations and see the potential impact.
Another issue is that the journalist does not understand the principle of swaps, which are used to hedge against rise of interest rates. As businessman agreed to hedg his exposure to rise in interest rates and pay fixed rate so it's quite obvious that if interest rates fall he will need to pay more to the bank but if interest rates rise he will benefit and will get money from his bank. He basically wants to benefit when interest rates fall but minimize exposure of raise in interest rates. You can't have win-win situation but If he would have wanted to benefit from any favorable movement in interest rates, he should have used options instead of swaps.
Maybe the whole problem is to do with the lack of knowledge of the businessman or unwillingness to consult his accountant.
