Maker’s Dai Peg Tools and Their Parallels to Central Bank Policy
Summary
This article uses Dai’s post-crash premium above one dollar to explain how Maker can influence stablecoin supply and demand. Unlike fiat-backed stablecoins, Dai is issued against overcollateralized debt, so arbitrageurs face collateral and capital costs. During market stress, falling collateral values can also prompt borrowers to repay Dai or add collateral, reducing supply as demand for a safe haven rises.
The author describes three policy levers: adjust borrowing fees and holder rewards, change collateral requirements or eligible collateral, and conduct open market purchases using newly issued Dai. These are compared with interest-rate policy, credit standards, and quantitative easing at central banks. The discussion highlights tradeoffs: negative holder rates are difficult when participation is optional, while looser collateral requirements raise insolvency risk. It is a conceptual case study rather than a performance test; several proposed interventions are presented as possible tools, not demonstrated solutions. The broader argument is that observable blockchain monetary experiments may offer lessons for policy design.
Key ideas
- Dai’s overcollateralized issuance makes its arbitrage mechanism different from that of fiat-backed stablecoins.
- Market stress can simultaneously increase demand for Dai and reduce its supply through borrower repayments or liquidations.
- Maker can influence the peg through borrowing fees and holder rewards, collateral rules, or open market operations.
- Optional participation makes negative rates difficult to implement without changes to the system.
- Loosening collateral rules may expand Dai supply but can increase insolvency risk.
