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.

The U.S. federal funds effective rate underwent a dramatic reduction in early 2020 in response to the COVID-19 pandemic. The rate plummeted from 1.58 percent in February 2020 to 0.65 percent in March, and further decreased to 0.05 percent in April. This sharp reduction, accompanied by the Federal Reserve's quantitative easing program, was implemented to stabilize the economy during the global health crisis. After maintaining historically low rates for nearly two years, the Federal Reserve began a series of rate hikes in early 2022, with the rate moving from 0.33 percent in April 2022 to 5.33 percent in August 2023. The rate remained unchanged for over a year, before the Federal Reserve initiated its first rate cut in nearly three years in September 2024, bringing the rate to 5.13 percent. By December 2024, the rate was cut to 4.48 percent, signaling a shift in monetary policy in the second half of 2024. The first rate cut in 2025 then set the rate at 4.33 percent. What is the federal funds effective rate? The U.S. federal funds effective rate determines the interest rate paid by depository institutions, such as banks and credit unions, that lend reserve balances to other depository institutions overnight. Changing the effective rate in times of crisis is a common way to stimulate the economy, as it has a significant impact on the whole economy, such as economic growth, employment, and inflation. Central bank policy rates The adjustment of interest rates in response to the COVID-19 pandemic was a coordinated global effort. In early 2020, central banks worldwide implemented aggressive monetary easing policies to combat the economic crisis. The U.S. Federal Reserve's dramatic reduction of its federal funds rate - from 1.58 percent in February 2020 to 0.05 percent by April - mirrored similar actions taken by central banks globally. While these low rates remained in place throughout 2021, mounting inflationary pressures led to a synchronized tightening cycle beginning in 2022, with central banks pushing rates to multi-year highs. By mid-2024, as inflation moderated across major economies, central banks began implementing their first rate cuts in several years, with the U.S. Federal Reserve, Bank of England, and European Central Bank all easing monetary policy.

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.

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 U.S. M1 money supply reached 18.43 trillion dollars in 2024, showing a modest increase from the previous year. While M1 grew gradually between 2000 and 2019, it experienced an unprecedented surge in 2020 due to the Federal Reserve's quantitative easing response to the COVID-19 pandemic. The most dramatic spike occurred in May 2020, when M1 jumped from 4.8 to 16.2 trillion dollars - more than tripling in a single month.

During the first half of the 2010s, the Italian government debt has been almost totally owned by private investors, such as banks and financial intermediaries. Most notably, more than one third of the national debt was held by foreign investors. After the 2011 Eurozone crisis, the European Central Bank started to purchase government bonds through a quantitative easing measure. Hence, the share of Italian debt owned by the Bank of Italy increased from less than four percent in 2010 to 22 percent in 2024.

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 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 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.

The annual value of new banknotes printed in the United States varied significantly between 2002 and 2023, showing a clear downward trend in recent years. The peak was in 2012, when the Bureau of Engraving and Printing produced banknotes valued at 386.6 billion U.S. dollars. During the quantitative easing of 2021, 319.7 billion U.S. dollars worth of banknotes were printed, marking the third-highest figure within the period. By 2023, the value of new banknotes printed had dropped by half, reaching 162.4 billion U.S. dollars. At the same time, the value of currency in circulation reached 2.29 trillion U.S. dollars in 2023.

In 2023, Japan had an average inflation rate estimated at 3.21 percent, marking the highest rate of inflation in Japan in almost a decade. However, this figure was still very low compared to most other major economies, such as Japan's fellow G7 members, four of which had inflation rates around six or seven percent in 2023 due to the global inflation crisis. Why is Japan's inflation rate lower? There are a number of contributing factors to Japan's relatively low inflation rate, even during economic crises. Japan eased its Covid restrictions more slowly than most other major economies, this prevented post-pandemic consumer spending that may have driven inflation through supply chain issues caused by higher demand. As the majority of Japan's food and energy comes from overseas, and has done so for decades, the government has mechanisms in place to prevent energy and wheat prices from rising too quickly. Because of this, Japan was able to shield its private sector from many of the negative knock on effects from Russia's invasion of Ukraine, which had a significant impact on both sectors globally. Persistent deflation and national debt An additional factor that has eased the impact of inflation on Japan's economy is the fact that it experienced deflation before the pandemic. Deflation has been a persistent problem in Japan since the asset price bubble burst in 1992, and has been symptomatic of Japan's staggering national debt thereafter. For almost 30 years, a combination of quantitative easing, low interest rates (below 0.5 percent since 1995, and at -0.1% since 2016), and a lack of spending due to low wages and an aging population have combined to give Japan the highest national debt in the world in absolute terms, and second-highest debt in relation to its GDP, after Venezuela. Despite this soaring debt, Japan remains the fourth-largest economy in the world, behind the U.S., China, and Germany.

In 2023, there were a total of 54.6 billion U.S. dollar notes in circulation, roughly 500 million more than in the previous year. Of these, 18.9 billion were 100-dollar bills, which had the highest volume in circulation. This was followed by the one-dollar bill, with 14.5 billion in circulation. During the observed period, the largest increase in the volume of currency in circulation occurred in 2020, as part of the quantitative easing measures introduced by the Federal Reserve.
