Ratticon - Welcome to the club on the economic crash!
I'm pretty sure it comes down to currency values. The British Pound is down ~15% in the last 4 months against the US dollar (
see chart), and Axiom can't afford to absorb the drop in value of the Pound without some adjustment. I imagine the ~20% hike versus ~15% drop in value is to protect themselves from additional swings in value of the Pound/Dollar ratio, which isn't hard to imagine given the wild ride we've all been on in the last month or two.
Hopefully in time it will stabilize...
