The estimated number of banks and thrifts in the United States fell from around ****** in 1920 to ****** in 1929, when the onset of the Great Depression would then see it fall further, below ****** in 1933. This marks a cumulative decline of over ****** banks and thrifts, which is equal to a drop of more than ** percent in 13 years. Tumultuous Twenties Despite the economic prosperity associated with the Roarin' 1920s in the U.S., it was a tumultuous decade in financial terms, with more separate recessions than any other decade. However, the ***** was also privy to frivolous lending policies among many banks, which saw the banking sector collapse in the wake of the Wall Street Crash in 1929. Many banks failed as the Great Depression and unemployment spread across the country, and customers or businesses could not afford to repay their loans. It was only after this financial crisis where the federal government began keeping more stringent and accurate records on its banking sector, therefore precise figures and the reasons behind these bank failures are not always clear. Franklin D. Roosevelt Just two days after assuming office in 1933, Franklin D. Roosevelt drastically declared a bank holiday, and all banks in the country were closed from ******* until ********. This break allowed Congress to pass the Emergency Banking Act on *******, which saw the Federal Reserve provide deposit insurance for all reopened banks thereafter. Through his first fireside chat, Roosevelt then encouraged Americans to re-deposit their money in the banks again, which successfully restored much of the public's faith in the banking system - it is estimated that over half of the cash withdrawn during the Great Depression was then returned to the banks by ********.

On October 29, 1929, the U.S. experienced the most devastating stock market crash in it's history. The Wall Street Crash of 1929 set in motion the Great Depression, which lasted for twelve years and affected virtually all industrialized countries. In the United States, GDP fell to it's lowest recorded level of just 57 billion U.S dollars in 1933, before rising again shortly before the Second World War. After the war, GDP fluctuated, but it increased gradually until the Great Recession in 2008. Real GDP Real GDP allows us to compare GDP over time, by adjusting all figures for inflation. In this case, all numbers have been adjusted to the value of the US dollar in FY2012. While GDP rose every year between 1946 and 2008, when this is adjusted for inflation it can see that the real GDP dropped at least once in every decade except the 1960s and 2010s. The Great Recession Apart from the Great Depression, and immediately after WWII, there have been two times where both GDP and real GDP dropped together. The first was during the Great Recession, which lasted from December 2007 until June 2009 in the US, although its impact was felt for years after this. After the collapse of the financial sector in the US, the government famously bailed out some of the country's largest banking and lending institutions. Since recovery began in late 2009, US GDP has grown year-on-year, and reached 21.4 trillion dollars in 2019. The coronavirus pandemic and the associated lockdowns then saw GDP fall again, for the first time in a decade. As economic recovery from the pandemic has been compounded by supply chain issues, inflation, and rising global geopolitical instability, it remains to be seen what the future holds for the U.S. economy.

China’s export benefits from the significant fiscal stimulus in the United States. This paper analyzes the global spillover effect of the American economy on China’s macro-economy using the Markov Chain Monte Carlo (MCMC)-Gibbs sampling approach, with the goal of improving the ability of China’s financial system to protect against foreign threats. This paper examines the theories of the consequences of uncertainty on macroeconomics first. Then, using medium-sized economic and financial data, the uncertainty index of the American and Chinese economies is built. In order to complete the test and analysis of the dynamic relationship between American economic uncertainty and China’s macro-economy, a Time Varying Parameter-Stochastic Volatility-Vector Autoregression (TVP- VAR) model with random volatility is constructed. The model is estimated using the Gibbs sampling method based on MCMC. For the empirical analysis, samples of China’s and the United States’ economic data from January 2001 to January 2022 were taken from the WIND database and the FRED database, respectively. The data reveal that there are typically fewer than 5 erroneous components in the most estimated parameters of the MCMC model, which suggests that the model’s sampling results are good. China’s pricing level reacted to the consequences of the unpredictability of the American economy by steadily declining, reaching its lowest point during the financial crisis in 2009, and then gradually diminishing. After 2012, the greatest probability density range of 68% is extremely wide and contains 0, indicating that the impact of economic uncertainty in the United States on China’s pricing level is no longer significant. China should therefore focus on creating a community of destiny by working with nations that have economic cooperation to lower systemic financial risks and guarantee the stability of the capital market.

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 June 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.

On March 10, 2023, Silicon Valley Bank (SVB) collapsed, marking the first bank failure in the United States since 2021. As the 16th largest bank in the country at the time, SVB's failure resulted in the loss of approximately *** billion U.S. dollars in assets - the second-highest asset loss since the 2008 global financial crisis. Two days later, New York-based Signature Bank also failed, with asset losses of roughly ***** billion U.S. dollars, making it the third-largest bank failure in U.S. banking history. Between 2001 and 2024, the United States experienced a total of *** bank failures.

As of January 2025, the largest all-time bankruptcy in the United States remained Lehman Brothers. The New York-based investment bank had assets worth 691 billion U.S. dollars when it filed for bankruptcy on September 15, 2008. This event was one of the major points in the timeline of the Great Recession, as it was the first time a bank of its size had failed and had a domino effect on the global banking sector, as well as wiping almost five percent of the S&P 500 in one day. Bank failures in the U.S. In March 2023, for the first time since 2021, two banks collapsed in the United States. Both bank failures made the list of largest bankruptcies in terms of total assets lost: The failure of Silicon Valley Bank amounted to roughly 209 billion U.S. dollars worth of assets lost, while Signature Bank had approximately 110.4 billion U.S. dollars when it collapsed. These failures mark the second- and the third-largest bank failures in the U.S. since 2001. Unprofitable banks in the U.S. The collapse of Silicon Valley Bank and Signature Bank painted an alarming picture of the U.S. banking industry. In reality, however, the state of the industry was much better in 2022 than in earlier periods of economic downturns. The share of unprofitable banks, for instance, was 3.4 percent in 2022, which was an increase compared to 2021, but remained well below the share of unprofitable banks in 2020, let alone during the global financial crisis in 2008. The share of unprofitable banks in the U.S. peaked in 2009, when almost 30 percent of all FDIC-insured commercial banks and savings institutions were unprofitable.

With the onset of the Global Financial Crisis in the late Summer of 2007, the United Kingdom was one of the first countries to experience financial panic after the United States. In September 2007, the bank Northern Rock became the UK's first bank to collapse in 150 years due to a bank run, as depositors reacted to the announcement that the bank would be seeking emergency liquidity support from the Bank of England by lining up outside their bank branches to withdraw money. The failure of Northern Rock was a bad omen for the UK economy and financial sector, as banks stopped lending to each other and to customers in what became known as the 'credit crunch'. Government bailouts, private bailouts By October 2008, many UK banks were facing a situation where if they did not receive external assistance, then they would have to default on their debts and likely have to declare bankruptcy. The UK's Labour government, led by Prime Minister Gordon Brown, announced that it would provide emergency funds to stabilize the banking system, leading to the part or full nationalization of some of Britain's largest financial firms. Specifically, Royal Bank of Scotland, Lloyds TSB, and HBOS received over 35 billion pounds in a government cash injection, while Barclays opted to seek investment from private investors in order to avoid nationalization, much of which came from the state of Qatar. The bailouts caused UK government debt ratios to almost double over the period of the crisis, while public trust in the financial system sank.

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. In January 2025, the Federal Reserve implemented another cut, setting the rate at 4.33 percent, which remained unchanged throughout the following months. 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.

Between the Wall Street Crash of 1929 and the end of the Great Depression in the late 1930s, the Soviet Union saw the largest growth in its gross domestic product, growing by more than 70 percent between 1929 and 1937/8. The Great Depression began in 1929 in the United States, following the stock market crash in late October. The inter-connectedness of the global economy, particularly between North America and Europe, then came to the fore as the collapse of the U.S. economy exposed the instabilities of other industrialized countries. In contrast, the economic isolation of the Soviet Union and its detachment from the capitalist system meant that it was relatively shielded from these events. 1929-1932 The Soviet Union was one of just three countries listed that experienced GDP growth during the first three years of the Great Depression, with Bulgaria and Denmark being the other two. Bulgaria experienced the largest GDP growth over these three years, increasing by 27 percent, although it was also the only country to experience a decline in growth over the second period. The majority of other European countries saw their GDP growth fall in the depression's early years. However, none experienced the same level of decline as the United States, which dropped by 28 percent. 1932-1938 In the remaining years before the Second World War, all of the listed countries saw their GDP grow significantly, particularly Germany, the Soviet Union, and the United States. Coincidentally, these were the three most powerful nations during the Second World War. This recovery was primarily driven by industrialization, and, again, the U.S., USSR, and Germany all experienced the highest level of industrial growth between 1932 and 1938.

Over the course of their first terms in office, no U.S. president in the past 100 years saw as much of a decline in stock prices as Herbert Hoover, and none saw as much of an increase as Franklin D. Roosevelt (FDR) - these were the two presidents in office during the Great Depression. While Hoover is not generally considered to have caused the Wall Street Crash in 1929, less than a year into his term in office, he is viewed as having contributed to its fall, and exacerbating the economic collapse that followed. In contrast, Roosevelt is viewed as overseeing the economic recovery and restoring faith in the stock market played an important role in this.

By the end of Hoover's time in office, stock prices were 82 percent lower than when he entered the White House, whereas prices had risen by 237 percent by the end of Roosevelt's first term. While this is the largest price gain of any president within just one term, it is important to note that stock prices were valued at 317 on the Dow Jones index when Hoover took office, but just 51 when FDR took office four years later - stock prices had peaked in August 1929 at 380 on the Dow Jones index, but the highest they ever reached under FDR was 187, and it was not until late 1954 that they reached pre-Crash levels once more.

Following the drastic increase directly after the COVID-19 pandemic, the delinquency rate started to gradually decline, falling below *** percent in the second quarter of 2023. In the second half of 2023, the delinquency rate picked up, but remained stable throughout 2024. In the first quarter of 2025, **** percent of mortgage loans were delinquent. That was significantly lower than the **** percent during the onset of the COVID-19 pandemic in 2020 or the peak of *** percent during the subprime mortgage crisis of 2007-2010. What does the mortgage delinquency rate tell us? The mortgage delinquency rate is the share of the total number of mortgaged home loans in the U.S. where payment is overdue by 30 days or more. Many borrowers eventually manage to service their loan, though, as indicated by the markedly lower foreclosure rates. Total home mortgage debt in the U.S. stood at almost ** trillion U.S. dollars in 2024. Not all mortgage loans are made equal ‘Subprime’ loans, being targeted at high-risk borrowers and generally coupled with higher interest rates to compensate for the risk. These loans have far higher delinquency rates than conventional loans. Defaulting on such loans was one of the triggers for the 2007-2010 financial crisis, with subprime delinquency rates reaching almost ** percent around this time. These higher delinquency rates translate into higher foreclosure rates, which peaked at just under ** percent of all subprime mortgages in 2011.

The U.S. commercial banking industry's return on assets (ROA) has experienced dramatic shifts over two decades. Peaking at **** percent in the first quarter of 2004, it plummeted to a historic low of ***** percent during the fourth quarter of 2008's global financial crisis. After a gradual recovery, the ROA stabilized around ******* percent in 2023, despite a decline to one percent in the final quarter. Throughout 2024, U.S. banks demonstrated relative consistency, with ROA fluctuating between 0.95 and 1.04 percent. Early 2025 saw an increase in the sector's ROA, reaching **** percent, the highest since the first quarter of 2023. In contrast, the European banking industry maintained a lower performance, with ROA averaging ******* percent during the same period. Steady growth amidst fluctuations in net operating income Despite the lowest quarterly net operating income of the U.S. banking industry being measured in the fourth quarter of 2008, at a negative ** billion U.S. dollars, the average quarterly income of all FDIC-insured institutions grew steadily after the global financial crisis, experiencing a sharp decrease due to the COVID-19 pandemic in the first half of 2020. After 2021, the industry saw another steady decrease in its quarterly income until it started to increase again towards the end of 2022. In 2024, the bank with the highest reported revenue was JPMorgan Chase. Stability and resilience in capital adequacy The common equity tier 1 (CET1) ratio of the U.S. commercial banking industry has shown resilience, with an upward trajectory throughout 2024. Despite sharp decreases due to global financial crises and the COVID-19 pandemic, the industry has demonstrated stability and gradual recovery in its capital adequacy, culminating in a ROA of **** percent in the first quarter of 2025.

As of June 9, 2020, the coronavirus outbreak posed a level ***** threat to businesses, meaning that severe and widespread economic impacts were likely. The composite index, which has level *** as its highest warning, was raised to level *** on March 12 and to level ***** on April 13.

Strong plans needed in response to coronavirus Countries are taking small steps on the road to economic recovery by gradually lifting lockdown measures. Manufacturing firms were among the first to return to work, and governments are now permitting shops, bars, and restaurants to reopen. However, there is no guarantee that consumers will return to their normal habits. In order to reduce the risks, businesses are being encouraged to activate contingency plans that include separating all essential operations from non-essential and focusing on high-priority areas and clients.

A focus on the U.S. economy COVID-19 has left the United States facing an economic crisis, and the country’s GDP fell by *** percent in the first quarter of 2020. Record numbers of Americans have lost their jobs during the pandemic, and the unemployment rate jumped to **** percent in April 2020. The Dow Jones, which monitors the stock prices of the ** largest companies in the United States, has rallied since the U.S. economy restarted but continues to feel the effects of a destructive period that wiped out years of gains in a matter of weeks.

As of June 17, 2024, the most shorted stock was for, the American holographic technology services provider, MicroCloud Hologram Inc., with 66.64 percent of their total float having been shorted. This is a change from mid-January 2021, when video game retailed GameStop had an incredible 121.07 percent of their available shares in a short position. In effect this means that investors had 'borrowed' more shares (with a future promise to return them) than the total number of shares available for public trading. Owing to this behavior of professional investors, retail investors enacted a campaign to drive up the stock price of Gamestop, leading to losses of billions when investors had to repurchase the stock they had borrowed. At this time, a similar – but less effective – social media campaign was also carried out for the stock price of cinema operator AMC, and the price of silver. What is short selling? Short selling is essentially where an investor bets on a share price falling by: borrowing a number of shares selling these shares while the price is still high; purchasing the same number again once the price falls; then returning the borrowed shares at a profit. Of course, a profit will only be made if the share price does fall; should the share price rise the investor will then need to purchase the shares back at a higher price, and thus incur a loss. Short selling can lead to some very large profits in a short amount of time, with Tesla stock generating over one billion dollars in short sell profits during the first week of March 2020 alone, owing to the financial crash caused by the coronavirus (COVID-19) pandemic. However, owing to the short-term, opportunistic nature of short selling, these returns look less impressive when considered as net profits from short sell positions over the full year. The risks of short selling Short selling carries greater risks than traditional investments, and for this reason financial advisors often recommend against this strategy for ‘retail’ (i.e. non-professional) investors. The reason for this is that losses from short selling are potentially uncapped, whereas losses from traditional investments are limited to the initial cost. For example, if someone purchases 100 dollars of shares, the maximum they can lose is the 100 dollars the spent on those shares. However, say someone borrows 100 dollars of shares instead, betting on the price falling. If these shares are then sold for 100 dollars but the price subsequently rises, the losses could greatly exceed the initial investment should the price rise to, say, 500 dollars. The risks of short selling can be seen by looking again at Tesla, with the company causing the greatest losses over 2020 from short selling at over 40 billion U.S. dollars.

The U.S. banking industry recorded its lowest quarterly net operating income during the fourth quarter of 2008, posting a loss of **** billion U.S. dollars amid the global financial crisis. In subsequent years, the average quarterly income of FDIC-insured institutions showed an overall upward trend, despite periodic fluctuations. The COVID-19 pandemic triggered a sharp decline in earnings during the first half of 2020, though the sector recovered and stabilized by late 2021. Following this recovery, the industry experienced another period of declining quarterly income. However, earnings began to rebound toward the end of 2022. The net income of the sector remained stable throughout 2024, and in the first quarter of 2025, the quarterly net income was **** billion U.S. dollars.

The Federal Reserve's balance sheet ballooned following its announcement to carry out quantitative easing to increase the liquidity of U.S. banks in early 2020. The balance sheet continued to grow in the following period as well, with a downward trend in 2023. As of February 29, 2024, the Fed's balance sheet amounted to roughly 7.6 trillion U.S. dollars. The most drastic increase in the observed period took place in the first half of 2020. This measure was taken to increase the money supply and stimulate economic growth in the wake of the damage caused by the COVID-19 pandemic. The Federal Reserve was not the only institution that implemented an expansionary monetary policy in response to the pandemic. For instance, the European Central Bank expanded its money supply in March 2020 and kept doing so over the following months. How do central banks increase the amount of money in circulation? Central banks can increase the money circulating in the economy in many ways. For instance, they can decrease banks’ reserve requirements to stimulate lending or decrease the interest rates to reduce the cost of borrowing for commercial banks. Alternatively, central banks can engage in open market operations (OMO) and buy securities such as government bonds from commercial banks or institutions. By conducting open market operations, the Federal Reserve expanded its balance sheet by seven trillion U.S. dollars between 2007 and 2023. All these measures aim to increase bank loans to entrepreneurs and consumers in order to stimulate employment and economic growth. Impact of COVID-19 on the U.S. economy The COVID-19 pandemic had a tremendous impact on national economies worldwide, and the United States was no exception. During the early months of the crisis, many lost their jobs, mostly those in lower-income categories. As a consequence, many Americans found it difficult to pay their rent and cover basic household expenses. Furthermore, in April 2022, most small business owners claimed that the pandemic had a large or moderate negative effect on their businesses. Overall, the gross domestic product (GDP) of the United States decreased by roughly 2.2 percent in 2020. In the following years, however, it increased notably, surpassing 25 trillion U.S. dollars in 2022.

The home mortgage debt of households and nonprofit organizations amounted to approximately 13.3 trillion U.S. dollars in the first quarter of 2024. Mortgage debt has been growing steadily since 2014, when it was less than 10 billion U.S. dollars and has increased at a faster rate since the beginning of the coronavirus pandemic due to the housing market boom. Home mortgage sector in the United States Home mortgage sector debt in the United States has been steadily growing in recent years and is beginning to come out of a period of great difficulty and problems presented to it by the economic crisis of 2008. For the previous generations in the United States, the real estate market was quite stable. Financial institutions were extending credit to millions of families and allowed them to achieve ownership of their own homes. The growth of the subprime mortgages and, which went some way to contributing to the record of the highest US homeownership rate since records began, meant that many families deemed to be not quite creditworthy were provided the opportunity to purchase homes. The rate of home mortgage sector debt rose in the United States as a direct result of the less stringent controls that resulted from the vetted and extended terms from which loans originated. There was a great deal more liquidity in the market, which allowed greater access to new mortgages. The practice of packaging mortgages into securities, and their subsequent sale into the secondary market as a way of shifting risk, was to be a major factor in the formation of the American housing bubble, one of the greatest contributing factors to the global financial meltdown of 2008.

The home mortgage debt of households and nonprofit organizations amounted to approximately 13.46 trillion U.S. dollars in the first quarter of 2025. Mortgage debt has been growing steadily since 2014, when it was less than ten billion U.S. dollars and has increased at a faster rate since the beginning of the coronavirus pandemic due to the housing market boom.

The Common Equity Tier 1 (CET1) ratio of the U.S. commercial banking industry rose steadily throughout 2023 and 2024, with the final quarter of 2024 marking the **** consecutive quarter of growth. However, this upward trend ended in the first quarter of 2025, as the CET1 ratio edged down slightly to ***** percent. Over the broader observation period, the most significant decline occurred in 2007, driven by the global financial crisis. Subsequent declines were recorded in 2019 due to the COVID-19 pandemic, and again in 2021 and 2022.
