A merchant banker in Wechsberg's account could tell you how a client's grandfather had behaved during a bad harvest. That was not sentiment; it was underwriting. Islamic finance is built on a principle of shared commercial risk, yet its institutions overwhelmingly finance through predictable receivables — and the usual explanations, capital rules and depositor expectations, only go so far. A bank cannot share risk in a business it does not know. The older merchant houses solved that problem with three forms of capital that do not appear on any balance sheet, and modern Islamic institutions have quietly been operating without them.
