The contributors of Terra-based decentralized finance (DeFi) protocol Anchor have proposed cutting terraUSD (UST) rates to an average of 4% from the current 19.5% as the broader Terra ecosystem seeks measures to protect UST’s peg with U.S. dollars.

“Decrease minimum interest rates to 3.5%, and maximum deposit rates to 5.5%, with a targeted interest rate of 4%,” the ongoing proposal describes.

Some 244,000 anchor (ANC) tokens have been used to place votes on “yes” at writing time. ANC is Anchor Protocol's governance token that users can deposit or stake to create new governance polls, or vote on existing pools started by users that have staked ANC.

Anchor is a savings, lending and borrowing platform built on the Terra platform that allows users to earn yields on UST deposits and take out loans against holdings. Critics have previously touted its “stable high interest rate” – as described on its website – as unsustainable due to the high amounts of money required to maintain those rates.

In the past few months, Anchor continued to operate as intended and became the biggest DeFi application on Terra. But UST’s recent depegging from the dollar has made the protocol’s grandiose plans go awry.

UST fell to as low as 22 cents on Wednesday amid outflows from Anchor and LUNA’s rapid drop, causing a downward spiral. UST has since recovered somewhat but the long-term recovery remains unclear.

“A depegged UST cannot sustain 18% APY any longer,” wrote Anchor contributor Daniel Hong in a relevant forum post. “While some may argue higher interest rates help with less UST circulating supply, when the stablecoin have already lost trust from the public due to a [two]-day depeg people would try to exit anyways.”

“One significant factor for today’s depeg was the release of Terra’s stability reserve into the Anchor reserve every time it was depleted, introducing newly minted UST that was not supposed to be there into circulation,” Hong wrote, explaining UST’s price plunge on Wednesday.

Hong, however, added the “fairly aggressive” change would be rolled back as and when deemed necessary, meaning the 4% interest rate may increase in the future should market conditions improve.
