You can use: a custom scenario of rate paths a flat scenario: unknown coupons and principal stay at the last known level (as of the calculation date) an implied scenario (default): market-implied paths of the base indicators, recovered from liquid floaters and inflation-linked government bonds The implied scenario estimates market expectations for the relevant base rates (for example overnight, inflation and policy rate) on the calculation date.
