Gaika+ Reference Benchmark Rates

The Gaika+ Reference Benchmark for each currency is the reference rate which will be used to calculate the yields of the daily swaps of your non-JPY cash to yen. IBKR uses a combination of internationally recognized reference rates (such Fed Funds), bank deposit rates, and dynamic interbank rates determined from foreign exchange and money markets to calculate a Gaika+ Reference Benchmark rate.

For information regarding the various external reference rates that contribute to the Gaika+ Reference Benchmark rate, see Benchmark Interest Calculation Reference Rate Descriptions.
