Are IB's Interest & Financing charges fair enough?

[affan]

Their interest paid for the major currencies is Bench Mark -0.5%. And their interest charged for major currencies is +1.5%. Doesn't that make currency trading a bit expensive with all the interest that is paid?

I also have a Tradestation account but couldn't find on their website how much interest they charge for other major currencies.

Oanda has much better rates, their account is not as insured though
