As of December 2024, the countries with the highest 10-year yields are the United Kingdom, the United States and Australia with 4.68, 4.38 and 4.21 percent, respectively. Of the largest economies by GDP, the United States saw the sharpest fall in absolute terms for 10-year government bond yields due to the coronavirus (COVID-19) pandemic. From a level of 1.51 percent in January 2020, yields on 10-year government bonds fell to 0.65 percent by April 2020, and had further fallen to 0.53 percent by July 2020 before starting to recover towards the end of the year. Conversely, countries that went into 2020 with already low bond yields like Japan, Germany and France actually saw a small increase in March 2020 - although these already low yields mean that these small changes are significant in relative terms.
