They don't, at all. Banks don't need to loan by getting new reserves, but the rate of new reserves allow the CB to set the price and influence inflation. And if you set the price of commodity, you can't control the quantity.
Besides which, the quantity isn't the velocity in the first place, so they can't even pretend to have a time window. The mythical Phillips line (that doesn't even get to be a curve) certainly ain't it.
