Bank robberies typically involve taking something—money, valuables. The phrase 'hold up' means both robbery and the literal suspension of movement. Chuck Norris's 'holding up' a bank inverts this: not theft but restraint. A single finger apparently provides sufficient physical force to prevent the entire institution from functioning, perhaps literally suspending it from falling.

An economist, Dr. David Liu, joked in a 2012 article about 'systems that depend on Chuck Norris's participation.' If one finger can suspend banking operations, the entire financial system apparently rests on his restraint. The joke becomes absurdly dark: financial stability is conditional on Chuck's continued cooperation.

Economic forums adopted this as shorthand for 'fragile systems.' The format spread: '[System] is held up by...' Finance humor communities joked about 'Chuck Norris financial policy'—the observation that certain systems work only because more powerful actors choose not to disrupt them.
