What is NOMURA Swap Index?


The NOMURA Swap Index is an index that shows the performance of yen interest rate swaps (fixed rate receiving side). Investment return indices and risk indicators are calculated for yen interest rate swaps of various maturities.


The NOMURA Swap Index investment return index and risk indicators are calculated from the daily market value of the yen interest rate swaps in question, which is in turn based on the yen interest rate swap rates and so on provided by Nomura.
