US Treasury Secretary Scott Bessent said his risky US gamble on Argentina's currency has paid off.

Bessent said American financial support had been repaid and the US no longer held any Argentine pesos in its exchange stabilisation fund.

The US had purchased the then-plunging currency last year in an effort to stave off further turmoil and boost the party of President Javier Milei, a key ally of President Donald Trump, in the run-up to national midterm elections.

The move sparked criticism from Democrats, who accused Bessent of risking taxpayer money on a country with a long history of financial turmoil.

In the end, Bessent said the manoeuvre had been a success.
