BIP15 proposes to increase LTV from 25% to 30%
There was somewhat of a black swan event recently. ICX had a double-airdrop snapshot while Binance deposits were suspended. This resulted in the Balanced DEX becoming a large point of ICX selling post-snapshot and a sharp spike in bnUSD price.
This triggered reverse-rebalancing heavily to absorb the demand for bnUSD and many borrower positions became locked. BIP15 should ease that pressure on borrowers and allow some to receive access to their collateral again to repay some of their debt.
