WORD TRENDS
The financial sense of toxic describes debts which are unlikely to be repaid and assets suddenly found to be worthless: banks will be pressured to come clean on the amount of toxic debt they hold ｜ no one wants to buy any of these toxic assets. Toxic has been used metaphorically to describe something very bad or harmful since the late 20th century （the scandal could be politically toxic）， and the specific financial sense is first recorded around 1990. Before that， though， risky stocks and bonds were referred to as toxic waste - they are dangerous to (financial) health and very difficult to dispose of.
