Inflation killed the penny. Now it’s coming for your dollar.

The decision to retire the penny addresses a symptom rather than the underlying cause. A coin costs more to produce than it is worth because inflation has steadily eroded its purchasing power over decades. Congress can legislate the denomination out of existence, but no vote changes the arithmetic that made it unviable.

That arithmetic applies to the dollar as well. The same cumulative rise in prices that rendered the penny impractical continues to work on larger denominations, quietly reducing what each unit buys. Retirement of a coin is a visible milestone; the erosion itself is gradual and easy to overlook.

For markets, the takeaway is that inflation is a persistent structural force, not a one-off event. Investors and policymakers watch currency debasement through purchasing-power data, interest-rate expectations, and hard-asset pricing. The penny's end is a reminder to monitor those signals rather than treat any single legislative fix as a resolution.
