Many ancient societies had recurring debt jubilees on approximately that time scale… for basically this reason.

Debt jubilee season comes, everyone’s debts are wiped clean.

Sucks for the lenders, great for the borrowers, but also everyone knows when it is scheduled.

That is pretty close to a reset of the playing field of your economy in many ways…

… though of course slavery did also exist in many of these societies, so… far from a perfect reset.
