The current banking crisis isn't a sudden panic run. Instead, it's a 'bank walk,' where deposits consistently move out of regional banks into higher-yield money market funds. This slower, sustained outflow creates a protracted crisis that unfolds between quarterly reports, masking its severity.

Quantitative Easing (QE) forced massive, often uninsured deposits onto bank balance sheets when loan demand was weak. These deposits were highly rate-sensitive. When the Fed began raising rates, this "hot money" quickly fled the system, contributing to the banking volatility seen in March 2023.

A core function of money is to be the 'final extinguisher of debt.' However, fiat currency is created as debt, meaning every dollar is both an asset and a liability. This inherent contradiction makes the entire financial system fundamentally fragile.

Only the Fed and commercial banks can create new, spendable money out of thin air. In contrast, credit creation, like in shadow banking, simply reallocates existing money from a saver to a spender. This distinction is crucial for understanding economic stimulus and risk.

Goldsmiths distinguished between customers wanting specific gold returned (bailment) and those depositing fungible coins. This latter category allowed them to lend out deposits, creating a de facto fractional reserve system long before it was formally institutionalized, revealing the organic origins of modern banking.

While bad credit might be the spark, the fuel for nearly every major financial crisis is a fundamental mismatch between assets and liabilities. This occurs when an entity holds illiquid investments but owes money to creditors who can demand it back on short notice, forcing fire sales.

Central banks evolved from gold warehouses that discovered they could issue more paper receipts (IOUs) than the gold they held, creating a fraudulent but profitable "fractional reserve." This practice was eventually co-opted by governments to fund their activities, not for economic stability.

While stablecoins gain attention, tokenized deposits offer similar benefits—like on-chain transactions—but operate within the existing, trusted regulatory banking framework. As they are simply bank liabilities on a blockchain, they may become a more palatable alternative for corporates seeking efficiency without regulatory uncertainty.

A deposit's value doesn't depend on the performance of the bank's specific underlying assets (like a particular mortgage). This insensitivity to private information is what makes them function like money. When this breaks, as with SVB, the deposit ceases to be money and becomes a risky claim you must analyze.
