The Nightmare Scenario
Recently, attacks have been leveled against Terra, suggesting that it is doomed to collapse as UST reaches unsustainable levels. Specifically, concerns have been raised that at a low enough LUNA price, users will no longer be able to redeem $1 of UST for $1 of LUNA. In what circumstances would the price and supply of LUNA and the supply of UST constitute a serious threat to UST redemption, i.e. create an imbalance wherein the UST-LUNA exchange mechanism would no longer function properly? What is the likelihood of such a scenario, and how might it be mitigated?
