As of October 16, 2024, the yield for a ten-year U.S. government bond was 4.04 percent, while the yield for a two-year bond was 3.96 percent. This represents an inverted yield curve, whereby bonds of longer maturities provide a lower yield, reflecting investors' expectations for a decline in long-term interest rates. Hence, making long-term debt holders open to more risk under the uncertainty around the condition of financial markets in the future. That markets are uncertain can be seen by considering both the short-term fluctuations, and the long-term downward trend, of the yields of U.S. government bonds from 2006 to 2021, before the treasury yield curve increased again significantly in 2022 and 2023. What are government bonds? Government bonds, otherwise called ‘sovereign’ or ‘treasury’ bonds, are financial instruments used by governments to raise money for government spending. Investors give the government a certain amount of money (the ‘face value’), to be repaid at a specified time in the future (the ‘maturity date’). In addition, the government makes regular periodic interest payments (called ‘coupon payments’). Once initially issued, government bonds are tradable on financial markets, meaning their value can fluctuate over time (even though the underlying face value and coupon payments remain the same). Investors are attracted to government bonds as, provided the country in question has a stable economy and political system, they are a very safe investment. Accordingly, in periods of economic turmoil, investors may be willing to accept a negative overall return in order to have a safe haven for their money. For example, once the market value is compared to the total received from remaining interest payments and the face value, investors have been willing to accept a negative return on two-year German government bonds between 2014 and 2021. Conversely, if the underlying economy and political structures are weak, investors demand a higher return to compensate for the higher risk they take on. Consequently, the return on bonds in emerging markets like Brazil are consistently higher than that of the United States (and other developed economies). Inverted yield curves When investors are worried about the financial future, it can lead to what is called an ‘inverted yield curve’. An inverted yield curve is where investors pay more for short term bonds than long term, indicating they do not have confidence in long-term financial conditions. Historically, the yield curve has historically inverted before each of the last five U.S. recessions. The last U.S. yield curve inversion occurred at several brief points in 2019 – a trend which continued until the Federal Reserve cut interest rates several times over that year. However, the ultimate trigger for the next recession was the unpredicted, exogenous shock of the global coronavirus (COVID-19) pandemic, showing how such informal indicators may be grounded just as much in coincidence as causation.

The Federal Reserve's balance sheet has undergone significant changes since 2007, reflecting its response to major economic crises. From a modest 0.9 trillion U.S. dollars at the end of 2007, it ballooned to approximately 6.76 trillion U.S. dollars by March 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 eight percent in 2022, the highest since 1991. However, by November 2024, inflation had declined to 2.7 percent. Concurrently, the Federal Reserve implemented a series of interest rate hikes, with the rate peaking at 5.33 percent in August 2023, before the first rate cut since September 2021 occurred in September 2024. 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 114.3 billion U.S. dollars, a stark contrast to the 58.84 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 281 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 174.53 billion U.S. dollars in the same year.

One of the major duties the Bank of England (BoE) is tasked with is keeping inflation rates low and stable. The usual tactic for keeping inflation rates down, and therefore the price of goods and services stable by the Bank of England is through lowering the Bank Rate. Such a measure was used in 2008 during the global recession when the BoE lowered the bank base rate from 5 percent to 0.5 percent. Due to the economic fears surrounding the COVID-19 virus, as of the 19th of March 2020, the bank base rate was set to its lowest ever standing. The issue with lowering interest rates is that there is an end limit as to how low they can go.

Quantitative easing

Quantitative easing is a measure that central banks can use to inject money into the economy to hopefully boost spending and investment. Quantitative easing is the creation of digital money in order to purchase government bonds. By purchasing large amounts of government bonds, the interest rates on those bonds lower. This in turn means that the interest rates offered on loans for the purchasing of mortgages or business loans also lowers, encouraging spending and stimulating the economy.

Large enterprises jump at the opportunity

After the initial stimulus of 200 billion British pounds through quantitative easing in March 2020, the Bank of England announced in June that they would increase the amount by a further one hundred billion British pounds. In March of 2020, the headline flow of borrowing by non-financial industries including construction, transport, real estate and the manufacturing sectors increased significantly.

In December 2024, the yield on a 10-year U.S. Treasury note was 4.39 percent, forecasted to decrease to reach 3.27 percent by August 2025. Treasury securities are debt instruments used by the government to finance the national debt. Who owns treasury notes? Because the U.S. treasury notes are generally assumed to be a risk-free investment, they are often used by large financial institutions as collateral. Because of this, billions of dollars in treasury securities are traded daily. Other countries also hold U.S. treasury securities, as do U.S. households. Investors and institutions accept the relatively low interest rate because the U.S. Treasury guarantees the investment. Looking into the future Because these notes are so commonly traded, their interest rate also serves as a signal about the market’s expectations of future growth. When markets expect the economy to grow, forecasts for treasury notes will reflect that in a higher interest rate. In fact, one harbinger of recession is an inverted yield curve, when the return on 3-month treasury bills is higher than the ten year rate. While this does not always lead to a recession, it certainly signals pessimism from financial markets.

The central bank policy rate in Japan stood at 0.5 percent in February 2025. In March 2024, the Bank of Japan raised short-term interest rates for the first time in 17 years, ending its negative interest rate policy. From August 2024 onwards, the central bank encouraged the uncollaterized overnight call rate to remain at 0.25 percent. A third rate hike to 0.5 percent was implemented in January 2025. In 2016, the Bank of Japan had introduced a policy of quantitative and qualitative monetary easing (QQE) with yield curve control, one component of which included controlling short-term and long-term interest rates through market operations.

The value of total assets held by the Bank of England increased significantly between 2013 and 2022. A particularly sharp increase took place in 2020 and 2021, triggered by the quantitative easing introduced as a response to the COVID-19 pandemic. The total assets of the Bank of England dropped in 2022 but remained above one trillion British pounds. In the third quarter of 2022, the British central bank held roughly 1.1 trillion British pounds worth of assets. In Europe, the largest central bank in terms of total assets is the Deutsche Bundesbank, which held almost three trillion euros at the end of 2022. The Bank of England ranked fourth.

The value of M2 money supply in the U.S. amounted to 20.86 trillion U.S. dollars in 2023, which was a slight decrease compared to the previous year. While between 2000 and 2019, the M2 money supply increased at a relatively slow pace, there was an exceptionally sharp increase in 2020, which was the result of the Federal Reserve's quantitative easing in response to the COVID-19 pandemic.

The M2 money supply in the United Kingdom increased rapidly between 2000 and 2023, with a particularly sharp increase in 2020 as a result of the quantitative easing in response to the COVID-19 pandemic. The rising tendency continued between 2021 and 2022, and by December 2022, the M2 money supply in the UK exceeded three trillion British pounds. 2023 marked the first year in over a decade that the M2 money supply declined, but it remained above three trillion British pounds.
