Interpretation of quarterly vs annual shock

General DSGE Modeling

Hello, I wanted to ask for an interpretation.
My model is quarterly and I annual interest rates. When I have a shock of 0.25, should I interpret IRF as 0.25 quarterly shock OR 0.25*4=1 annual shock?

Thanks.

What do you mean with

?
If your interest is quarterly and 1 is used to denote 1% instead of 100%, then 0.25 is a 25 basis point shock to the quarterly interest rate, which amounts to 100 basis points annually.
