MakerDAO co-founder Rune Christensen said in Discord that MakerDAO may choose to sell all of its USDC exposure in the protocol, a move that could trigger a decoupling of DAI from the U.S. dollar and needs to be prepared for that scenario.
According to data from Maker burn, 80% of the collateral assets behind DAI are currently stablecoins and 60% are USDC.
Rune Christensen sees decoupling as an acceptable risk and will discuss the matter on the governance call. The recent U.S. Treasury sanctions on Tornado Cash was the reason for considering decoupling. Sanctions were more severe than he initially considered and freeze after sanctions.
