This claim is automatically judged true on Jan 1, 2007. Its purpose is to determine how much FX investors will pay for a guaranteed long term small profit. Some people have said in fx-discuss that they can easily make 5-10%/year in short term claims; if this feeling is widespread, the maximum offer to buy T2007 will be significantly less than 99.
Another way of thinking about this claim is that it's a bet that you're not going to find anything more attractive to do with your cash between now and 2007. Sellers are betting that you will.
Note that someone who sells a YES at 99 (buys a NO at 1) and later buys it back at 98 (sells it at 2) has doubled her money.
