local_analytic_rate_fixings(*, curves=NoInput.blank, solver=NoInput.blank, fx=NoInput.blank, vol=NoInput.blank, settlement=NoInput.blank, forward=NoInput.blank)#

Calculate the sensitivity to rate fixings of the Instrument, expressed in local settlement currency per basis point.

Examples

In [131]: curve1 = Curve({dt(2000, 1, 1): 1.0, dt(2010, 1, 1): 0.75}, id="Eur1mCurve")

In [132]: curve3 = Curve({dt(2000, 1, 1): 1.0, dt(2010, 1, 1): 0.70}, id="Eur3mCurve")

In [133]: irs = IRS(dt(2000, 1, 1), "20m", spec="eur_irs3", curves=[{"1m": curve1, "3m": curve3}, curve1])

Parameters:

curves (_Curves, optional) – Pricing objects. See Pricing on each Instrument for details of allowed inputs.
solver (Solver, optional) – A Solver object containing Curve, Smile, Surface, or Cube mappings for pricing.
fx (FXForwards, optional) – The FXForwards object used for forecasting FX rates, if necessary.
vol (_Vol, optional) – Pricing objects. See Pricing on each Instrument for details of allowed inputs.
settlement (datetime, optional) – The assumed settlement date of the PV determination. Used only to evaluate ex-dividend status.
forward (datetime, optional) – The future date to project the PV to using the disc_curve.

Return type:

DataFrame

Notes

This analytic method will index the sensitivities with series identifier according to the Curve id which has forecast the fixing.
