The interest rate spreads narrow as you borrow more. Each currency is in its own account. The use a tiered system. A less than 10K USD equivalent account provides 0% interest, 10K-100K provides BM overnight - 0.5%, 100K+ provides BM-0.25%. These rates are for major currencies. The rates are different for the smaller currencies.
As for borrowing, less than 100K is BM+1.5%, over 100K-1M is BM+1%, 1M+ is BM+0.5%

IGMarkets will take off 2% the interest rate differential between the 'central market rates'. I'm not sure if central market rate means LIBOR or central bank rates.
Oanda are a forex trading broker. Withdrawing funds costs £10 or AUD 20 or USD 20 or EUR 20. The interest rates are good though.
