+1 for lobo here. We need something quite more granular than 30 days to monitor the peg. Algofi used a rotating 24 hour window. If it remained greater than 1% below peg 0.5% would be added to the interest rate and vice versa if it was above the peg. Rinse and repeat. That’s not to say it’s the “right way” to do it, just that’s what comes to mind when I think of proactive peg management.
As there’s talk of the smart contracts being rewritten, in the future this could likely be automated.
