Bank Capital Is Not a Pile of Cash Set Aside
Admati corrects a common misunderstanding: capital concerns the funding side of a balance sheet, not a reserve of idle cash. Assets can remain invested while a larger share is funded with equity rather than promises to creditors.
- Cash is an asset; capital describes funding.
- Capital ratios concern claims on the funding side of the balance sheet.
- More equity does not require banks to stop investing or lending.
- Confusing cash and capital distorts regulatory debate.
“cash not cash is not equity. Capital is not cash.”
“Capital is about how you fund It's not cash reserve.”
