Capital Controls

Capital controls are government restrictions on money moving across borders, including limits on foreign currency purchases, caps on overseas transfers, and forced conversion of export earnings. During Greece's 2015 banking crisis, ATM withdrawals were capped at 60 euros per day. Argentina, China, and Nigeria have maintained various forms of control for years at a time.

Why it matters

Governments impose capital controls to defend currency pegs, stop bank runs, and trap domestic savings inside the local financial system. For savers the effect is blunt: wealth is confined to a currency that is often depreciating, and legal exits are rationed or priced at punitive official exchange rates. Controls tend to arrive suddenly, at the exact moment citizens most want to move money, because that is precisely when governments most need them to stay.

In the gold vs bitcoin debate

Gold has been the classic escape from capital controls, but it must physically cross a border, where it can be detected and seized; governments have policed gold smuggling for as long as controls have existed. Bitcoin moves as information, so a saver can cross a border with nothing but a memorized seed phrase while the coins remain on a global ledger. This is among the strongest practical arguments for bitcoin in countries with restricted financial systems, though on-ramps and off-ramps remain points of enforcement.
