But the pin could have been some other event, at some other time. All crashes have catalysts, but the specific catalyst is usually irrelevant, in hindsight.
Ppl default on loans because they lack cash flow
banks didn't account for this with lax lending standards
banks go bankrupt but TARP style program bails out banks
hopefully people stay in their homes ...somehow. (some kind of mortgage payment moratorium?)
Pretty sure the ratings fraud got fixed. Also pretty sure they didn't just go back to handing loans out to anyone with a pulse. I'm sure there's some crazy intricate financial instruments made up of dogshit still around, but it's probably going to be a smaller percentage of the bank's balance sheet.
Canadian banks have been hit hard due to falling oil prices and expected resultant bankruptcies.
American banks will get hit by rising unemployment.
