In January 2020, prior to the onset of the global coronavirus (COVID-19) pandemic, three of the seven largest economies by GDP had negative yields for two-year government bonds (Japan, Germany and France). With the onset of the pandemic, two-year bond yields in these countries actually rose slightly - in contrast to the other major economies, where yields fell over this period. As of December 2024, yields for two-year government bonds exhibited fluctuations across all countries. Notably, Japan showed a slight upward trend, while China experienced a modest decline.Negative yields assume that investors lack confidence in economic growth, meaning many investments (such as stocks) may lose value. Therefore, it is preferable to take a small loss on government debt that carries almost no risk to the investor, than risk a larger loss on other investments. As both the yen and euro are considered very safe assets, Japanese, German and French bonds were already being held by many investors prior to the pandemic as a hedge against economic downturn. Therefore, with the announcement of fiscal responses to the pandemic by many governments around March 2020, the value of these assets rose as confidence increased (slightly) that the worst case may be avoided. At the same time, yields on bonds with a higher return fell, as investors sought out investments with a higher return that were still considered safe.

The Federal Reserve's balance sheet has undergone significant changes since 2007, reflecting its response to major economic crises. From a modest *** trillion U.S. dollars at the end of 2007, it ballooned to approximately **** trillion U.S. dollars by July 2025. This dramatic expansion, particularly during the 2008 financial crisis and the COVID-19 pandemic - both of which resulted in negative annual GDP growth in the U.S. - showcases the Fed's crucial role in stabilizing the economy through expansionary monetary policies. Impact on inflation and interest rates The Fed's expansionary measures, while aimed at stimulating economic growth, have had notable effects on inflation and interest rates. Following the quantitative easing in 2020, inflation in the United States reached ***** percent in 2022, the highest since 1991. However, by *********, inflation had declined to *** percent. Concurrently, the Federal Reserve implemented a series of interest rate hikes, with the rate peaking at **** percent in ***********, before the first rate cut since ************** occurred in **************. Financial implications for the Federal Reserve The expansion of the Fed's balance sheet and subsequent interest rate hikes have had significant financial implications. In 2023, the Fed reported a negative net income of ***** billion U.S. dollars, a stark contrast to the ***** billion U.S. dollars profit in 2022. This unprecedented shift was primarily due to rapidly rising interest rates, which caused the Fed's interest expenses to soar to over *** billion U.S. dollars in 2023. Despite this, the Fed's net interest income on securities acquired through open market operations reached a record high of ****** billion U.S. dollars in the same year.
