The 'money-on-demand' system is fragile and high risk.

Fractional-reserve banking allows banks to lend out most deposits while keeping only a fraction in reserve. This practice amplifies credit expansion during boom periods but creates vulnerability during runs.

Critics argue the model relies on continuous confidence and central bank intervention. Without deposit insurance or emergency liquidity, bank runs spread rapidly.

Supporters counter that the system maximizes capital allocation and economic growth. They emphasize regulatory oversight and modern monetary frameworks mitigate historical risks.

Recent stress in regional banking sectors highlights ongoing fragility. Policymakers debate reform options including higher reserve requirements or alternative structures.

The debate reflects deeper tensions between financial innovation and stability. Markets continue pricing in assumptions about perpetual central bank backstops.

Ultimately the discussion centers on whether current frameworks adequately balance efficiency with resilience in an interconnected global economy.
