Socialized Losses happen when Paradex Insurance Fund is bankrupt due to large amounts of unprofitable liquidations. Paradex is built to minimize the probability of such an event but it can still happen. In this case the exchange would have insufficient USDC funds to meet withdrawal requests for all client funds.
During periods of insufficient capitalization Paradex applies Socialized Loss charge to all withdrawals. Socialized Loss Factor represents how much percentage each withdrawal will be charged at current point in time in order to offset the loss. Only users who withdraw during those "shortfall" periods are affected by Socialized Losses.
Once the Insurance Fund is re-capitalized (though profitable liquidations or fund transfer) Paradex stops applying Socialized Loss charge to withdrawals.
For a given trading account, USDC Settlement Balance represents the USDC balance that this account would have if all its open positions were closed at current Mark Price :
The Bankruptcy Amount of an account is equal to :
i.e. Bankruptcy Amount is positive only if account will be bankrupt at current Mark prices. Otherwise it is zero.
The exchange Bankruptcy Amount is equal to :
If Exchange Bankruptcy Amount is positive (i.e. Insurance fund has negative value or shortfall from bankrupt user accounts is higher than Insurance Fund value), Socialized Loss Factor is greater than 0 and all withdrawals will be penalized by this factor.
Only withdrawals are subject to socialized loss penalty, users who do not withdraw are not affected
Insurance Fund has initially 1'000 UDSC balance and no open positions.
There are three traders on the exchange : Alice, Bob and Charlie. Each of them has a 1'000 USDC balance. The oracle price of USDC is 1 USD.
Therefore. the Total Exchange USDC Balance is
Alice buys 50 XYZ-USD-PERP against Bob at a 100 USD
The Mark Price of XYZ-USD-PERP suddenly crashes down to 40
Charlie withdraws 500 USDC : The Insurance Fund receives
and Charlie's withdrawal address receives
The Insurance Fund takes over Alice account. Note that Bankruptcy Amount is unchanged (1'000 USDC)
The Mark Price of XYZ-USD-PERP quickly moves up to 70
Now the Insurance Fund position (taken over from Alice) only has
Unrealized PnL. This means that the Insurance Fund is not bankrupt anymore and has
This brings the Exchange Bankruptcy Amount to 0 and the Socialized Loss Factor to 0%.
Therefore, withdrawals are now no longer subject to any loss.
