The Incident/Update
June 22, 2019 marks a critical stress test for MakerDAO and its decentralized stablecoin DAI. As Bitcoin rockets past $11,000 — surging 8% in a single session — the broader crypto market experiences one of its most violent rallies of the year. Ethereum climbs 4.65% to $309, and altcoins across the board post double-digit gains. For MakerDAO, the largest decentralized finance protocol by total value locked at this time, the question becomes whether DAI maintains its dollar peg through the turbulence.
MakerDAO operates as the backbone of DeFi on Ethereum. Users lock ETH as collateral in Collateralized Debt Positions and generate DAI against it. With ETH surging past $300 for the first time in months, the collateralization ratios across the system shift dramatically. Positions that sat comfortably over-collateralized suddenly find themselves even further in the green — but the speed of the move introduces its own category of risk.
The protocol governs approximately $300 million in total value locked at this point in 2019, a figure that makes it the undisputed king of DeFi. Each CDP represents a leveraged bet on ETH, and a sudden price reversal could trigger cascading liquidations. The system’s stability depends on the liquidation mechanism functioning correctly under extreme volatility — exactly the scenario unfolding on June 22.
Technical Post-Mortem
MakerDAO’s liquidation mechanism works through automated auction processes. When a CDP’s collateralization ratio falls below the threshold of 150%, the protocol triggers a liquidation event. A penalty fee applies, and the collateral goes to auction where keepers — specialized market participants — bid to cover the outstanding DAI debt. On June 22, the system faces the inverse problem: rapidly appreciating collateral that creates an unexpected dynamics shift.
As ETH surges from roughly $295 to $309 in a matter of hours, CDP holders find their positions significantly over-collateralized. This theoretically makes the system safer — more buffer means more room for a price correction. However, the mechanics of DAI supply respond to these market conditions. When collateral appreciates, CDP holders can generate more DAI without opening new positions. This increases DAI supply at a pace that tests market absorption capacity.
The Stability Fee — the interest rate paid by CDP holders — stands at 19.5% at this point, a rate set by MakerDAO governance to manage DAI supply and demand dynamics. This elevated rate reflects earlier governance decisions aimed at tightening DAI supply after the protocol struggled with maintaining its peg earlier in the year.
Governance Impact
MakerDAO’s governance operates through MKR token holders who vote on critical protocol parameters. In June 2019, the governance system remains relatively nascent, with a small group of large MKR holders wielding disproportionate influence over executive votes. The Stability Fee adjustments throughout early 2019 demonstrate the growing pains of on-chain governance.
The protocol executed multiple Stability Fee hikes in the months leading to June 2019, raising rates incrementally from 0.5% to 19.5% in an effort to shrink DAI supply and restore the peg. Each hike required a governance vote, and the lag between proposal, voting, and implementation sometimes allowed market conditions to shift before the fee changes took effect.
The broader governance conversation in June 2019 centers on Multi-Collateral DAI — the long-awaited upgrade that would allow assets beyond ETH to serve as collateral. This upgrade represents a fundamental shift in MakerDAO’s risk profile, introducing new oracle dependencies, liquidation parameters per collateral type, and the DAI Savings Rate as a tool for demand-side management.
TVL Shifts
MakerDAO’s total value locked stands at approximately $300 million on June 22, 2019, representing roughly 60% of the entire DeFi ecosystem. Compound Finance and Synthetix trail at a distance, with TVL figures in the tens of millions. MakerDAO’s dominance reflects both the protocol’s first-mover advantage and the limited DeFi landscape at this stage of the market cycle.
The surging ETH price inflates the USD-denominated TVL figure even without new capital entering the system. An ETH position worth $280 million in collateral on Friday becomes worth $300 million on Saturday purely through price appreciation. This creates a somewhat misleading picture of DeFi growth — the headline TVL number rises, but the underlying ETH deposits may remain flat.
On-chain metrics show approximately 2.3 million ETH locked in CDPs at this point, generating roughly 85 million DAI in circulating supply. The ratio of DAI outstanding to ETH locked provides a crucial measure of system leverage and, by extension, systemic risk.
Long-Term Prognosis
MakerDAO enters the second half of 2019 as the clear leader in a DeFi ecosystem still finding its footing. The protocol’s survival through the June rally demonstrates the resilience of its liquidation mechanics, even as governance processes show their limitations in responding to rapid market shifts. The Multi-Collateral DAI upgrade, expected later in 2019, promises to address many of the single-collateral system’s constraints.
The broader implications extend beyond MakerDAO itself. As the flagship DeFi protocol, its performance under stress sets the tone for institutional perception of decentralized finance as a whole. A failure to maintain the peg during a major rally would have cascading effects across every protocol building on top of DAI — from lending platforms to decentralized exchanges.
For DeFi advocates, June 22 provides validation that the system works under pressure. For skeptics, the 19.5% stability fee and governance centralization highlight the gap between the current state of DeFi and the vision of a truly decentralized financial system. The truth, as always, lives somewhere between these two positions — and the coming months determine which narrative prevails.

ETH surging to 309 was actually good for MakerDAO collateral ratios. the real stress test is a flash crash not a rally. backwards concern
makerdao with $300m tvl in 2019 was the entirety of defi. now there are single protocols with 10x that. dai held its peg through the june 2019 pump too
the real stress test was black thursday 2020, not this. eth went from $300 to $100 in days and maker had to do emergency auctions. june 2019 was a warmup
florian_m black thursday 2020 was the actual nightmare. june 2019 was a bull case for makerdao, not a stress test
june 2019 was the stress test that proved the system. march 2020 was the one that nearly broke it. different events, different lessons
dai_holder 300M TVL for the ENTIRE defi market in 2019. now a single liquid staking protocol has 50x that. insane growth in 5 years
cdp_veteran_ exactly. 300M was the WHOLE defi market. now UNI alone is bigger than that. the growth chart is vertical
cdp_archaeologist the growth chart is vertical but TVL comparisons across eras are misleading. 300M in 2019 was real usage, 15B in 2024 is mostly liquidity farming
cdp_auditor_ comparing 300M TVL to 15B is apples to oranges but the point about liquidity farming inflating numbers is valid. makerdao had real usage, most of the 2024 TVL was incentive driven
dai_holder dai held through the 2019 volatility like a champ. the real test was march 2020 black thursday when eth dropped 40% in a day and liquidations cascaded
300M TVL in 2019 MakerDAO is cute compared to what DeFi reached in 2021. that said the CDP liquidation mechanics were untested at scale back then
Marta L. CDP mechanics got tested alright. march 12 2020 liquidated everyone and DAI went to 1.08. this 2019 rally was a walk in the park compared to black thursday
ETH at 309 during BTC pump to 11K. those were the days when 309 felt expensive. try telling that to someone who bought the top in 2021
ETH at 309 during the BTC pump to 11K felt expensive at the time. you could have bought ETH at 140 two months earlier. context matters
ETH at $309 during the june 2019 pump felt expensive. and it was, relative to $140 a few months earlier. but compared to where ETH went after, it was still a fire sale
anyone who had a cdp open during that $11k btc rally was printing dai at a massive profit. collateralization ratios went through the roof
eth at $309 and people thought that was expensive. funny how that works
300M TVL in 2019 and people still called DeFi a buzzword. MakerDAO was literally the only protocol doing anything real back then
defi_sherpa_ calling MakerDAO a buzzword in 2019 was wild. it was literally the only protocol with real economic activity. everything else was testnets with tokens
ETH at $309 during the june 2019 BTC pump felt like the top. sold half my stack. still hurts
dai holding its peg through the june 2019 BTC pump was the moment defi proved it was more than an experiment. black thursday 2020 almost killed it though
Mira T. black thursday almost killed DAI because the oracle lagged during the crash. collateral auctions cleared at near zero. MakerDAO survived by luck and community bailout not design
0 bid auctions happened because keepers were 3 guys with no capital. the oracle lag was secondary. chainlink feeds got wired in after
keeper_cap_ three keepers and no competition inside a 300M protocol. liquidation 2.0 with proper debt floors fixed it but took two years to ship
everyone watched btc do 8% and forgot DAI was trading well off peg that same week. stress tests run in both directions
