Clubs are dependent on the price decisions of their fuel suppliers, who are in turn dependent on the price decisions of the fuel producers. If I was in a club making decisions about what hire rates to charge at the moment I'd be very wary of cutting prices in response to an apparent down turn in the barrel price. It'll be a self-fulfilling prophecy anyway - if piston engine activity continues to decline, demand for avgas will decline so the unit cost of production will go up.
Then of course there's the effect of the immoral self-serving b***ds who make money out of talking up the price and have recently realised that there's no limit to the profits they can make because the world is so dependent on hydrocarbons.
Still, we don't have to worry about fuel prices at the moment because the weather means there's no flying happening in any case.
