If we cut the HBD interest rate, a few speculators may dump their holdings and cause a "crash," but once that is over, we can find a new equilibrium.

If we maintain the status quo, the debt builds, and I agree that is not healthy in the long term.

Which witnesses can we persuade to start reducing the rate, say 1% at a time ove the next few months, to avoid a shock? It makes sense to keep HBD returns above the US inflation rate, so 10% might still be reasonable IMHO.
