Yes but what hedge funds would do (are undoubtedly doing) is raise a huge amount of money on margin and use it to arbitrage the spread between these and related instruments with other durations. Of course this can go horribly wrong; read the book "When Genius Failed".

The Trillion Dollar Bet is also a good, high-level documentary.
