Brexit terrifies me. The economy is already feeling the effects of the falling pound. Trade is going to be in chaos, affecting jobs (especially if some people get their way and all the foreigners are pushed out of the country. On the one hand, yes it should mean less competition, but on the other, the EU is clearly going to use trade agreements as a stick to keep the borders open to free movement.)
Don't forget that interest rates have been ridiculously low for a very long time. When they inevitably go up, there will be less money in punters pockets.
If anything, the time to raise prices is now, during the calm before the storm. Get some savings stashed away and pay off any debts now.
