I agree with psces88. There's no need to "lock in" the loss now (interest paid), when you only possibly, maybe, need the money in the future. It's just a hypothetical, which would probably not occur.

And if you really need cash later, you can always make a "cash withdrawal" using your credit card. That will incur a 2% fee when you make the withdrawal, plus (if you don't pay in full when the credit card statement comes at the end of the month) any interest due later.

The interest rate is listed as "current finance rate" in my statement (citibank). Should be in your's too. Mine says 17.5% pa now. IIRC, it sometimes goes as high as 2% per month in the past, which is about 27% pa (per year). Your savings account may pay 2% pa, if you're lucky.

public bank interest rates now is from 0% to 1.2% pa. That is not a typo, or a rounding error. They are paying 0% if you have a low balance in your account!
