Zambia's kwacha just notched its strongest weekly performance against the dollar in over a year and a half—and there's a clear reason why. The government's crackdown on foreign currency usage in domestic deals has traders scrambling to unload dollars. It's a classic move: when authorities restrict greenback circulation, demand dries up fast and the local currency suddenly looks more attractive. For anyone tracking emerging market dynamics or managing cross-border transactions, this is textbook policy-driven volatility. The kwacha's rally, the biggest since October 2023, shows how quickly regulatory signals can reshape currency flows. Whether this momentum holds depends on how strictly the authorities enforce the restrictions.
