The nascent decentralized finance ecosystem on Ethereum is experiencing its first real stress test. MakerDAO, the protocol behind the DAI stablecoin and the undisputed king of DeFi in early 2019, has been forced to hike its stability fees dramatically — from a modest 0.5% to a staggering 19.5% — as it struggles to maintain the dollar peg of its DAI token. The move, which unfolded through a series of governance votes in the spring of 2019, has left borrowers reeling and raised fundamental questions about the viability of algorithmic stablecoins.
TL;DR
- MakerDAO stability fees surged from 0.5% to 19.5% in early 2019
- DAI stablecoin struggled to maintain its $1 peg despite aggressive rate hikes
- 1.86 million ETH locked in MakerDAO at start of 2019 (~$260 million)
- DeFi ecosystem still in its infancy with roughly 65,000 users total
- Ethereum at $251.76 as broader crypto market recovers
From Rock-Bottom to Sky-High: The Rate Hike Spiral
When MakerDAO launched, its stability fee — effectively the interest rate borrowers pay to open collateralized debt positions (CDPs) — sat at an attractive 0.5%. This ultra-low rate made it one of the cheapest ways to obtain leverage in all of crypto. Users would lock up ETH as collateral and generate DAI against it, paying minimal fees for the privilege.
But as Ethereum prices surged during the spring 2019 rally — ETH climbed from roughly $130 in January to above $250 by late May — the dynamics of the system shifted. Rising ETH prices meant collateral values increased, which should theoretically have strengthened the system. Instead, an oversupply of DAI pushed the stablecoin below its $1 target. Borrowers were incentivized to keep their positions open rather than repay, creating a persistent supply overhang.
MakerDAO governance responded with a series of increasingly aggressive rate hikes. Each vote pushed the stability fee higher — first to 2.5%, then 3.5%, 7.5%, 11.5%, 14.5%, 16.5%, and eventually to 19.5%. The goal was to make borrowing expensive enough that users would close their CDPs, reducing DAI supply and pushing the price back to $1.
DAI’s Stubborn Discount
Despite the dramatic rate increases, DAI continued to trade below $1 for extended periods, at times dipping to $0.96 or lower on major exchanges. This persistent discount frustrated holders and raised uncomfortable questions. If an interest rate of 19.5% was not enough to restore the peg, what would be? Critics began describing the situation as a “loan shark situation,” noting that borrowers were effectively being squeezed while the mechanism designed to maintain stability appeared to be failing.
The root cause was structural. In a system where borrowers lock volatile ETH to generate DAI, the incentive structure during a bull market inherently works against peg maintenance. Rising ETH prices mean users can generate more DAI without posting additional collateral, even as the incentive to repay diminishes because the cost of borrowing in DAI terms decreases relative to ETH gains.
DeFi in 2019: A One-Horse Race
MakerDAO’s dominance of the DeFi landscape in early 2019 was nearly absolute. At the start of the year, MakerDAO was the only DeFi protocol with significant funds — approximately 1.86 million ETH locked, valued at roughly $260 million. The total value locked in all of DeFi was barely larger than MakerDAO alone.
By May 2019, the situation was slowly beginning to diversify. New protocols were emerging on Ethereum, exploring lending, derivatives, and decentralized exchange. But the ecosystem remained tiny in absolute terms, with an estimated cumulative total of roughly 65,000 unique addresses interacting with DeFi protocols.
The challenges facing MakerDAO were, in many ways, the growing pains of an entire ecosystem learning in public. Every governance decision, every rate hike, and every peg deviation was being scrutinized as a case study in whether decentralized finance could actually work at scale.
The Ethereum Backbone
All of this was playing out against the backdrop of Ethereum’s own price recovery. ETH was trading at $251.76 on May 25, 2019, with a market capitalization of $26.7 billion according to CoinMarketCap data. The recovery from sub-$130 levels at the start of the year represented a near-doubling that had significant implications for every DeFi protocol built on the network.
Higher ETH prices meant higher collateral values for CDP holders, but also increased liquidation risks if the market reversed sharply. The interconnected nature of these dynamics — between Ethereum’s price, MakerDAO’s stability mechanism, and the broader DeFi ecosystem — highlighted both the promise and the fragility of building financial infrastructure on a volatile base layer.
Why This Matters
The MakerDAO rate hike saga of spring 2019 was DeFi’s first true governance crisis, and it established patterns that would repeat throughout the ecosystem’s evolution. The tension between decentralized governance and market realities, the challenges of maintaining stablecoins through algorithmic means, and the cascading effects of base-layer volatility on built protocols — all of these themes would define DeFi for years to come. That borrowers were paying 19.5% interest while the system still struggled to maintain a $1 peg was a humbling reminder that reimagining finance from first principles was going to be harder than anyone expected.

got liquidated during the 19.5% fee hike era. was borrowing DAI against ETH and the math stopped making sense real quick
cdp_survivor the liquidation ratio plus 19.5% fee basically forced everyone to close positions. the peg barely held anyway
cdp_survivor i feel you. was collateralized at 2x and still almost got liquidated when ETH tanked. 19.5 percent fee on top was salt in the wound
19.5% fees while ETH was dropping. double whammy for CDP users. that was the real intro to DeFi risk management
1.86 million ETH locked in MakerDAO at $260 million total. compare that to todays TVL numbers and you see how early this was
borrowing at 0.5% then getting hit with 19.5% through governance votes you couldnt even participate in without holding MKR. early defi was rough for retail
going from 0.5% to 19.5% in increments is how you know the peg was genuinely threatened. not just governance theater
incremental hikes showed the peg was genuinely under pressure. not governance theater, real economic stress on the system
DAI couldnt hold its peg even at 19.5% stability fee. everyone blames ETH collateral ratio but the real issue was there was zero organic demand for DAI back then
65,000 total DeFi users in early 2019. thats smaller than most discord servers now lol
those MKR holders voting for fee hikes while CDP users got squeezed was the first real class conflict in DeFi
governance_lord MKR holders voting for 19.5% while CDP users got squeezed was peak DeFi class warfare. same dynamic exists today just with different tokens
1.86 million ETH locked at $260M total value. that is about $140 per ETH of DeFi TVL. insane how early this all was
Stellan B. 140 dollars per ETH of TVL is insane context. now we have L2s with billions and people still complain about adoption
remembering the exact moment my CDP went underwater. ETH at ~250 and a 19.5% fee on top, the liquidation bot ate my position in minutes
vault_widow_ brutal. the 150% collateralization ratio plus 19.5% fee meant any ETH dip was a liquidation event. no breathing room at all
19.5% fee and DAI still slipped below peg. proves that governance rate hikes alone cant save an algorithmic stablecoin when the underlying collateral is dumping. real backing wins
borrowing DAI at 0.5% then watching governance crank it to 19.5% through votes you couldnt participate in without MKR. the retail borrower got squeezed so MKR holders could protect the peg
19.5% and DAI still traded below a dollar for weeks. the fee hike was necessary but it proved that algorithmic stablecoins need deep collateral not just economic incentives
MakerDAO stability fees going from 0.5% to 19.5% in months while DAI still couldnt hold peg. that was the first real proof that algorithmic stablecoins need more than just rate adjustments
19.5% stability fee and DAI still traded below a dollar for weeks. the peg mechanism was genuinely broken and governance kept hiking rates hoping it would fix itself
1.86 million ETH locked in MakerDAO at the start of 2019 worth about $260M. the entire DeFi ecosystem had 65,000 users total. wild to think about now
maker_vault_casualty the retail borrower squeeze was the point. MKR holders needed DAI peg restored and CDP users were the ones paying for it through governance votes they couldnt afford to participate in
