You currently have net negative interest rates. If money is sound, that's not possible so it will certainly be higher than it is now. I think "risk free" rates (which don't actually exist but people believe in them,) will be super close to zero, but risk will be much more appreciated, to the point that 99.9% of borrowers will see even nominal interest rates higher than they do now. We won't see interest rates go down, we will see it become such a bad bargain, that no one will borrow, except from absolute desperation. If you observe history you will see this for as long as there was a self custodial gold standard.
