Why does rollover Interest Credit or Debit Occur?

Trading with currencies is trading with cash. Going long with a currency is similar to holding a deposit in a bank and interest will be earned. Going short on a currency is similar to borrowing money on which interest is to be paid. With traded currencies the relationship is more complicated. With a currency pair, a currency with a positive balance is being hold (currency going long) and a currency with a negative balance (currency going short) is being held simultaneously. The difference in the interest rate of the two countries is called the interest-rate differential.

Being credited or debited for rollover is dependent on two factors: 1) the position being hold (long or short) and 2) the interest-rate differential between the two currencies in the pair being traded.

Interest is being paid on the currency borrowed and interest is being earned on the currency being bought. Effectively, interest is being earned or paid depending on the direction of the trade.

Currency being bought with a higher interest rate than the one being borrowed will result in a positive net differential rate. Funds will be earned. Selling a currency with a higher interest rate than the currency being bought will result in a negative net differential, and interest will be paid for the rollover. The rollover costs/credits are based on the position size and the larger the position size, the larger the cost or gain will be.

Interest rates are not cast in concrete and are changing constantly with changing economic conditions.
