The effects of a bust will be rising unemployment, followed by bad debts, then debt deflation, and then finally falling asset prices.
A mortgage, which is a form of secured debt, presents a good example. Let's say you purchased a home by taking out a mortgage. That same home would be secured as collateral for the loan, meaning that if you defaulted on payments to the bank, the home would be repossessed by the bank. If the potential selling price of the home decreased in value while you were still making payments to the bank, you would be in the middle of a debt deflation scenario.
