Afghanistan's currency has been the world's best performer over the past quarter.
  • Afghanistan's afghani has surged 9% against the US dollar over the past three months.
  • The Taliban's tight controls have made the currency the world's best performer since July 1.
  • But Afghanistan's economy has suffered since the group reclaimed power in 2021.

The best-performing currency of the third quarter isn't the surging US dollar – it's Afghanistan's afghani.
