Cyclical history unlikely to provide much support for GBP
As markets will slowly begin to see that the next move in UK rates will be down, not up, we think a change in rate expectations could drag the currency down.
The cyclical story is also unlikely to provide much support for the GBP, as short-term cyclical indicators such as PMIs have started to worsen again.
Finally, unless and until there is a rebound in risk appetite, supported by an improving global outlook, difficult domestic forces are likely to continue weighing on the GBP.
