So the credit crunch claims another victim. Me. I don't have a huge amount in my ISA, but the interest rate almost means I might as well stick it under the mattress. Here's how my ISA has performed over the last 5 years: 2006 - Â£115.34 on Â£3479 2007 - Â£152.16 on Â£4679 2008 - Â£101.19 on Â£2773 2009 - Â£67.79 on Â£3973 2010 - Â£4.60 on Â£5241 Bloody ridiculous. And it's not like the interest rate on loans has come down anywhere near the rate that the savings rate has.
