Suitcases of forged banknotes aren’t just the stuff of heist movies and spy novels. Banks and governments around the globe are constantly working to prevent fraudsters from introducing fake cash into circulation – and some countries are more successful in their efforts than others.
Nations typically use parts per million (ppm), a metric borrowed from chemistry, to monitor counterfeit currency. They give a score by measuring the number of fake banknotes found in circulation for every one million genuine notes. Most nations aim to stay below the 15 ppm mark, though quite a few have seen an uptick in counterfeited cash.
Read on to discover how much fraudulent money is floating around in some of the world’s major currencies, ranked from the lowest ppm rate to the highest.

Malaysia’s counterfeiting index is well below the international benchmark of 15 ppm. The country’s score peaked at 1.9 ppm in 2015 and had been on a steady decline, reaching just three fake notes per 10 million in 2022, or 0.3 ppm. Until recently, that is…
The rate jumped to 1.6 ppm in 2023, according to Bank Negara Malaysia, which attributes the increase to a single incident involving 3,868 pieces of forged ringgit notes.

Despite the ringgit being one of the world’s least forged currencies, Malaysia’s central bank continues to improve and enhance its anti-counterfeiting measures.
Security details on ringgit banknotes include raised printing, 3D watermarks, clear windows, and a thread that changes colour when the note is tilted.

Fake cash in Australia reached its peak in June 2015 when the rate exceeded 30 ppm, before steadily declining to the much lower average of 6.7 ppm in 2023.
The Reserve Bank of Australia credited this decrease to law enforcement efforts, which included shutting down major counterfeiting operations during the 2015-2019 period. The transition to cashless payments, lockdowns during the COVID-19 pandemic, and a new series of banknotes with improved security features have also played their part.

In 2020, the $100 banknote surpassed the $50 bill to become Australia’s most forged denomination – and the bank suspected that one specific counterfeiter drove this change.
However, recent updates mean fraudsters face more of a challenge. The legitimate bill now features an image of a flying owl that appears to flex its wings and change colour when tilted, while a 3D fan shows different colour lines. Rolling colour effects feature on both sides of the note.
