Rather than estimating a loss threshold from a distribution, it asks a conditional question — if this scenario played out, what would it do to our liquidity, our hedged and unhedged exposures, and our compliance with loan covenants?

They say little about the tail beyond that threshold, which is exactly where the losses that threaten a business live. Stress testing asks a different, conditional question: not 'how bad is a 95th-percentile outcome?' but 'what happens IF this particular severe scenario occurs?' VaR gives you a probability-weighted summary; stress testing gives you the consequence of a named event, regardless of how likely it is. They're complements — one measures the body of the distribution, the other explores the tail.",{"question":253,"answer":254},"What is reverse stress testing?","Reverse stress testing runs the logic backwards. Instead of starting from a scenario and reading off the impact, you start from an unacceptable outcome — a covenant breach, a liquidity shortfall, a loss that would threaten the business — and work out what combination of market moves would cause it. It's often more revealing than forward scenarios because it forces you to confront the specific conditions that would actually break you, rather than the comfortable scenarios a team tends to choose on its own.
