Hyperinflation

Hyperinflation is extreme, accelerating inflation, conventionally defined by economist Phillip Cagan as price increases exceeding 50 percent per month, a pace that compounds to nearly 13,000 percent per year. Weimar Germany in 1923, Hungary in 1946, and Zimbabwe in 2008 are the canonical cases; in each, the national currency became effectively worthless within months.

Why it matters

Hyperinflation is what total monetary failure looks like. It typically begins when a government facing deficits it cannot finance through taxes or borrowing turns to printing money, and it accelerates once the public loses confidence and races to spend currency before it depreciates further. Savings denominated in the currency are wiped out, contracts and pensions become meaningless, and commerce retreats to barter or foreign money. While rare in large developed economies, hyperinflation has occurred dozens of times in the past century, which is why students of monetary history treat it as a recurring risk rather than a curiosity.

In the gold vs bitcoin debate

Every hyperinflation triggers a flight into assets the state cannot print. Historically that meant gold, foreign banknotes, and real property. In recent episodes in Venezuela and Argentina, bitcoin and dollar stablecoins joined the list, because they can be acquired and moved with a phone even when banks are failing and borders are closed. Gold remains the time-tested refuge; bitcoin's advocates argue it is the more practical one for people who need to carry wealth out of a collapsing system. The pattern repeats often enough that monetary historians treat the printing press, not the shortage or the war, as the common cause.
