It seems zero interest rates were not enough to keep DAI stable.
A MakerDAO (MKR) governance proposal enacted on Tuesday set interest rates on most assets, with the notable exclusion of Ether (ETH), back above 0%.
According to Daistats, interest rates for the USDC-A, WBTC and other minor vaults are now back to being at 2%, meaning that the protocol is once again collecting revenue for those who borrow DAI against these assets.
Lowering interest rates is generally seen as a way of stimulating DAI creation, which is supposed to lower its price to its intended $1 peg.
While Cointelegraph recently reported that the price finally stabilized after a long period of overpricing, the situation was not to last.
