Prev Wed Fixing

Key Prev Wed Fixing in Yield Curve Bma refers to the historical fixing of the BMA index assumed to apply on the most recent past Wednesday.

This entry is ignored if no such a historical index is needed by the involved BMA swaps.

In particular, if today is Wednesday, then today's BMA fixing is implied by the yield curve and the entry here - which refers to the Wednesday a week ago - is completely ignored.
If on the other hand today is Thursday, then the first cash flow of all BMA swaps will be based on yesterday's BMA index fixing given by the entry here.
