The US developed a coin circulation problem in 2020

As people reduced the frequency with which they paid for things in cash and change during the COVID-19 pandemic, opting for tap-to-pay systems or online shopping instead, the number of coins in circulation decreased.

The US dollar has served as the world's reserve currency for 80 years—but is its dominance coming to an end?

Although no viable alternative exists yet, the dollar's share of central bank reserves has decreased from 73% to 58% from 2001 to 2024, and President Trump's 2025 tariffs have sped up this trend.
