SBF keeps saying there was a liquidity crisis at FTX, which is 100% not true. A liquidity crisis implies that he took deposits, flipped them into good, but illiquid investments, and ran into trouble because people asked for more cash than FTX had on hand.
FTX actually had a solvency crisis, where he took deposits, put them in completely inappropriate investments (many of which are now worthless, all of which were speculative nonsense) and is now revealed to have done that.
He's using the concepts of "bank runs" and "liquidity crises" because that's sort of an "aww shucks, got caught in an unfortunate circumstance" situation when what he actually did was one of the stupidest and most malicious things anyone in "finance" has ever done.
