MakerDAO, one of the most influential players in the decentralized finance (DeFi) space, is undergoing a pivotal shift in its risk and liquidity management strategy. The governance community is actively exploring the inclusion of USDC—a centralized stablecoin—as collateral to back its decentralized stablecoin DAI. This move aims to enhance market liquidity, reduce systemic risk during volatile market conditions, and strengthen the resilience of the DAI ecosystem.
While this decision aligns with practical financial needs, it also sparks debate about decentralization principles. How does introducing a centralized asset affect the integrity of a decentralized stablecoin? And what are the real implications for liquidity, governance, and user trust?
Let’s dive into the details.
The Liquidity Crisis That Sparked Change
On a turbulent Thursday marked by a sharp drop in ETH prices, MakerDAO faced a critical shortfall. During collateral liquidation auctions, certain actors won bids at 0 DAI, meaning they acquired valuable assets without injecting sufficient funds back into the system. This flaw led to a financial deficit exceeding $4.5 million.
To cover this loss, MakerDAO was forced to mint and auction additional MKR tokens, a last-resort mechanism that dilutes existing token holders. The total deficit surpassed $5 million, highlighting a deeper issue: insufficient DAI liquidity during high-volatility events.
This incident exposed a key vulnerability: when demand for DAI spikes—such as during liquidations or governance auctions—there may not be enough DAI available on the market to meet demand without significant price slippage or premium inflation.

Why Add USDC as Collateral?
To mitigate future liquidity crunches, MakerDAO community members proposed onboarding USDC as a new collateral type. This would make USDC the third supported asset after ETH and BAT, but with a crucial difference: it’s a stablecoin.
Key Benefits:
- Reduced Volatility Risk: Unlike ETH, USDC maintains a stable value, minimizing the risk of under-collateralization.
- Improved Liquidity Provision: Market makers can now generate DAI directly from USDC holdings, enabling faster response to demand surges.
- Stable Price Peg: By enabling arbitrage opportunities between DAI and USDC, the system can better maintain DAI’s $1 peg.
For example, imagine a market maker holding $1 million in USDC. A client wants to convert $100 million into DAI. Without USDC collateral support, fulfilling this request would cause massive slippage. But with it, the market maker can deposit their own $1 million USDC plus $99 million more, mint $100 million in DAI instantly, and fulfill the order smoothly.
As one community member noted:
“Given the uncertain liquidity risk for DAI in the market, both the community and Maker Foundation members are advocating for adding USDC as collateral to help mitigate this risk.”
How USDC Integration Supports Governance and Auctions
Another critical reason for this change is to ensure the smooth operation of MKR token auctions and collateral liquidations.
When ETH prices fall sharply—say below $56—over **$52 million worth of ETH** could be liquidated simultaneously. If DAI lacks sufficient liquidity, auction participants may struggle to acquire enough DAI to bid, leading to failed auctions and further destabilizing the system.
By allowing direct conversion from USDC to DAI, participants can access DAI more easily, reducing friction in auctions and helping maintain system solvency.

USDC Collateral: Key Parameters
The proposal passed governance voting on March 17 and has already been integrated into the protocol. Here are the initial parameters set by MKR holders:
- Collateralization Ratio: 125%
(i.e., $125 USDC required to generate $100 DAI) - Debt Ceiling: $20 million
(maximum DAI that can be minted via USDC) - Stability Fee: 20% per year
These conservative settings reflect cautious optimism. The high stability fee discourages retail users from using USDC to mint DAI for everyday purposes—it’s not financially rational. Instead, this feature is designed for market makers, arbitrageurs, and liquidation participants who need reliable access to DAI during stress periods.
As of March 18 at noon UTC, nearly $3 million worth of USDC had already been locked into the system.
Kevin Jedidiah of Parafi Capital commented:
“Maker adding USDC as a collateral option makes sense—it provides timely liquidity injection during market turmoil and strengthens DAI’s resilience.”
Community Backlash: Centralization vs. Practicality
Despite the clear benefits, the move has sparked controversy.
DAI was originally created as a decentralized alternative to centralized stablecoins like USDT and USDC. Now, relying on USDC—even partially—as collateral feels contradictory to that vision.
Critics argue:
- It introduces counterparty risk (Circle controls USDC reserves and can freeze funds).
- It undermines trust in DAI’s decentralization narrative.
- It sets a precedent: if USDC is acceptable today, what stops other centralized assets tomorrow?
Supporters counter that:
- The debt ceiling is low ($20M), limiting exposure.
- The high stability fee ensures only professional actors use it.
- Survival trumps purity: A functioning system is better than an ideologically pure but fragile one.
This tension reflects a broader challenge in DeFi: balancing ideological integrity with real-world functionality.
Frequently Asked Questions (FAQ)
Q: Can anyone use USDC to mint DAI?
A: Technically yes—but it’s not practical for most users. With a 125% collateral ratio and 20% annual fee, you’d pay more than you gain. It’s primarily intended for institutional players like market makers.
Q: Does this make DAI fully backed by centralized assets?
A: No. USDC-backed DAI is capped at $20 million. The vast majority of DAI remains backed by decentralized assets like ETH.
Q: What happens if USDC depegs or gets frozen?
A: A depeg would trigger under-collateralization risks. However, the 125% ratio provides a buffer. If USDC were frozen, MakerDAO could initiate emergency shutdown procedures to protect the system.
Q: Is this a temporary measure?
A: While not officially labeled as such, many view it as a pragmatic short-to-medium-term solution until more decentralized liquidity solutions (like peer-to-pool credit models) mature.
Q: How does this affect MKR token holders?
A: It reduces systemic risk, which protects MKR value. Fewer emergency minting events mean less dilution for holders.
Q: Could other stablecoins be added later?
A: Possibly—but each addition would require governance approval. Assets like DAI++ or EUROC might be considered if they meet security and decentralization thresholds.

The integration of USDC as collateral marks a turning point for MakerDAO—a shift from ideological purity toward resilient pragmatism. While it challenges long-held beliefs about decentralization, it also demonstrates maturity in recognizing that survival in volatile markets often requires adaptive strategies.
As DeFi continues to evolve, projects like MakerDAO will face more such trade-offs. The key lies in transparency, governance participation, and maintaining user trust—even when making tough calls.
