How the World Works

United States

The world’s largest economy and issuer of its main reserve currency. That lets it borrow heavily in its own currency, but its deficits are large even in good years.

1 · Government finances

How much it owes, and what it costs

Government debt in the US is about 127% of GDP this year, on IMF estimates, 18 points higher than in 2019. The government is running a deficit of 8.5% of GDP: even before paying 3.6% of GDP in interest, it spends more than it collects. The IMF expects debt to rise to about 145% by 2031.

2 · External position

What it earns and spends abroad

The US runs a current account deficit of 3.9% of GDP (about $1,263bn): it spends more abroad than it earns, and relies on foreign investors to fund the gap.

3 · Economy and markets

Growth, prices and borrowing costs

The IMF expects the economy to grow 2.3% this year in real terms, with inflation averaging 3.6%. Its 10-year borrowing cost, 4.96%, is below the economy’s nominal growth of roughly 5.9% (growth plus inflation). Over time, that helps keep debt stable relative to GDP.
