Credit Expansion

Credit expansion is the growth of lending and, with it, the broad money supply, since bank loans create new deposits. It accelerates when interest rates are low and lenders are confident. The United States M2 money supply grew roughly 40 percent between early 2020 and early 2022, one of the fastest expansions on record.

Why it matters

Credit expansion is how most new money actually enters the economy, dwarfing physical currency issuance. Managed well, it finances growth; run hot, it inflates asset bubbles and consumer prices, and its reversal, credit contraction, is the anatomy of every deflationary bust from 1929 to 2008. Austrian school economists argue expansions driven by artificially low rates systematically misdirect investment, planting the errors that the subsequent recession exists to liquidate. The 2020 to 2022 episode, followed by the worst inflation in four decades, gave the old debate fresh material.

In the gold vs bitcoin debate

Both assets are, at heart, bets against unrestrained credit expansion. Gold's fixed geology once anchored the entire banking system, and its price still rises when investors doubt monetary discipline. Bitcoin was launched in January 2009 with a newspaper headline about bank bailouts embedded in its first block, an explicit response to the credit crisis then unfolding. Neither asset can stop credit from expanding; each offers a place to stand outside the expansion.
