I'm being very specific here, they had ~175b in deposits. There assets may or may not have been more or less than deposits, that is immaterial. They were insolvent because they did not have enough cash/credit/liquid capital to cover the predicted withdrawals. That is the why they are insolvent. Long term, yes, the asset state would have been a problem, and would(should) have been marked up as a ~25% loss on the bonds that were being hammered by inflation. but at no point would that have been a big issue for the stability of the bank. It would have hammered their share price, but not deposits. It probably would have required a change of management, but again, not fatal. The issue here is that "asset insolvent" is rarely described like that, it normally at the point where you declare bankruptcy because no-one will buy you out because you liabilities are way more than your income.
