Liquidations

Liquidations & Synthetix Staking

When a staker's Collateralization Ratio (C-Ratio) falls below the liquidation ratio, they are subject to liquidation, a risk management mechanism crucial for maintaining the protocol's stability. If the staker's C-Ratio doesn't improve within a certain period, protocol users will take action to rectify the situation by liquidating a portion of their staked SNX.

The Process

Upon falling below the required C-Ratio (see Current Protocol Parameters), stakers enter a period during which they must rectify their C-Ratio. Failure leads to one of the following scenarios, each with distinct implications and penalties:

  1. Forced Liquidation:

    • If a staker does nothing after being flagged, the protocol enforces liquidation. A penalty applies not to their total staked SNX but to the amount that is liquidated to bring their C-Ratio back to the target.

    • This penalty, often around 60%, is redistributed within the protocol, incentivizing active participation and penalizing negligence.

  2. Self-Liquidation:

    • Stakers proactive in managing their stakes may opt for self-liquidation, incurring a smaller penalty, typically around 50% on the portion of SNX being liquidated.

    • This approach offers a less punitive measure for those seeking to exit their positions or reduce their exposure deliberately.

  3. Rebalancing to Avoid Liquidation:

    • Stakers who adjust their C-Ratio promptly, either by burning sUSD or by additional staking to elevate their C-Ratio above the protocol's target, will avoid any liquidation process.

    • It demonstrates responsible staking behavior, contributing positively to network stability.

  4. Option for Self-Liquidation at Any Time:

    • The protocol may offer mechanisms for stakers to initiate self-liquidation even before reaching critical thresholds, providing greater control over their staking positions and potential outcomes.

Why Are Liquidations Vital to the Protocol?

Liquidations serve multiple essential functions:

  • They enforce discipline among stakers, ensuring that everyone within the network maintains adequate collateral levels.

  • Active network participants can help stabilize the overall network C-Ratio by initiating liquidation processes for at-risk stakers.

  • They help address the issue of 'zombie' wallets, which, due to lost keys or abandonment, no longer contribute actively to network health.

Example of a Liquidation

Consider a staker, Bob, who begins with a healthy position but experiences market volatility that jeopardizes his C-Ratio:

Bob stakes 1000 SNX and mints 1000 sUSD. With SNX at $2, his collateral is worth $2000, and his C-Ratio is 200%. If the SNX price drops to $1.50, his collateral value falls to $1500, pushing his C-Ratio down to 150% and triggering the liquidation process.

If Bob's position is forcibly liquidated (scenario 1), the protocol will determine how much SNX needs to be sold to restore Bob's C-Ratio to the 400% target. The penalty applies to this portion, not the entirety of Bob's staked SNX. For instance, if 250 SNX needs to be liquidated, a 60% penalty means losing 150 SNX, with the remaining 100 SNX used to repurchase sUSD and burn it to restore the C-Ratio.

If Bob opts for self-liquidation (scenario 2), he might face a 50% penalty on the liquidated SNX, reducing his loss slightly in the process of C-Ratio restoration.

Alternatively, if Bob manages to rebalance his stake (scenario 3), by adding more SNX or burning some sUSD, he could maintain or even improve his C-Ratio, thus avoiding any penalties.
