Looking at that chart my interpretation is. Target / average is 3-5% overall. During a recession it's normally 2%. During the 70's and 80's there was a crazy boom where it went up to crazy levels averaging 15% with it going between 10-20%. Since 2008 it's went crazy the other way where we are into unknown and unprecedented territory staying below 1% for the first time ever and for over a decade. Realistically speaking it should only be able to go up but we are still far off the opposite swing the other way of the 70's and 80's. If I was a bookies I would say it's 3-1 that they will go negative. Evens that they go up and 1-2 that they hover around the 0% mark. It's impossible to say and the above saying go for a tracker. If they do swing upwards to curb inflation you would be crying. The way I see it is they can't go much cheaper. So no real benefit to a tracker. They have a great chance of staying put and a small chance of going up. I'm looking to fix long, take all the extra cash I would normally overpay and invest it in stocks and shares and commodities. I'm in the lowest band and plenty of equity I'll probably take £50k out when I remortgage and still be in the lowest band.
