1945-2009 on debt by sector as a fraction of
GDP 1960-2008 The
Federal Reserve issues routine reports on the flows and levels of debt in the
United States. As of the first quarter of 2010, the Federal Reserve estimated that total public and private debt owed by American households, businesses, and government totaled $50 trillion, or roughly $175,000 per American and 3.5 times GDP.
Interest payments on debt by US households, businesses, governments, and nonprofits totaled $3.29 trillion in 2008. The financial sector paid an additional $178.6 billion in interest on
deposits. In 1946, the total US
debt-to-GDP ratio was 150%, with two-thirds of that held by the federal government. Since 1946, the federal government's debt-to-GDP ratio has since fallen by nearly half, to 54.8% of GDP in 2009. The debt-to-GDP ratio of the financial sector, by contrast, has increased from 1.35% in 1946 to 109.5% of GDP in 2009. The ratio for households has risen nearly as much, from 15.84% of GDP to 95.4% of GDP.
Financial sector In 1946, the US financial sector owed $3 billion of debt, or 1.35% of GDP. By 2009 this had increased to $15.6 trillion, or 109.5% of GDP. This refers to securities guaranteed and mediated by federal agencies and GSEs such as
Ginnie Mae,
Fannie Mae, and
Freddie Mac, among others. This group also includes the
mortgage pools that are used as collateral in
collateralized mortgage obligations. The proportion of financial sector debt owed in the form of GSE and federally related mortgage pools has remained relatively constant – $863 million or 47% of total financial sector debt in 1946 was in such instruments; this has increased to 57% of financial sector debt in 2009, although this now represents over $8 trillion. Bonds recovered in the 1980s, representing approximately 25% of financial sector debt throughout the 1990s; however, between 2000 and 2009, bonds issued by the financial sector had increased to 37% of financial sector debt, or $5.8 trillion. According to the McKinsey Global Institute, the
2008 financial crisis was caused by "unsustainable levels of household debt." The ratio of debt to household income rose by about one-third from 2000 to 2007.
Nonfinancial business In 1946, US nonfinancial businesses owed $63.9 billion of debt or 28.8% of GDP. By 2009 this figure had risen to $10.9 trillion or 76.4% of GDP. State and local governments have significant financial assets, totaling $2.7 trillion in 2009. In 2009, these included $1.3 trillion in credit market debt (that is, debt owed by other sectors to state and local governments). These figures do not include state and local retirement funds. State and local retirement funds held $2.7 trillion in assets at the end of 2009.
Federal government In 1946, the federal government owed $251 billion of debt or 102.7% of GDP. By 2009 this figure had risen to $7.8 trillion, but the federal government's debt-to-GDP ratio had fallen to 54.75%. The federal government held $1.4 trillion in assets at the end of 2009. This is more than double the assets held by the federal government in 2007 ($686 billion), mainly due to the acquisition of
corporate equities, credit market debt, and cash. The federal government held $223 billion in corporate equity at the beginning of 2009; this had fallen to $67.4 billion at the end of that year. These figures also do not include debt that the federal government owes to federal funds and agencies such as the
Social Security Trust Fund. It also does not include "unfunded liabilities" to entitlement programs such as
Social Security and
Medicare either as debt or accounting liabilities. According to official government projections, the Medicare is facing a $37 trillion unfunded liability over the next 75 years, and the Social Security is facing a $13 trillion unfunded liability over the same time frame.
Negative real interest rates Since 2010, the U.S. Treasury has been obtaining
negative real interest rates on government debt. Such low rates, outpaced by the
inflation rate, occur when the market believes that there are no alternatives with sufficiently low risk, or when popular institutional investments such as insurance companies,
pensions, or bond, money market, and balanced
mutual funds are required or choose to invest sufficiently large sums in Treasury securities to hedge against risk.
Lawrence Summers,
Matthew Yglesias and other economists state that at such low rates, government debt borrowing saves taxpayer money, and improves creditworthiness. In the late 1940s through the early 1970s, the US and UK both reduced their debt burden by about 30% to 40% of GDP per decade by taking advantage of negative real interest rates, but there is no guarantee that government debt rates will continue to stay so low. In January, 2012, the U.S. Treasury Borrowing Advisory Committee of the Securities Industry and Financial Markets Association unanimously recommended that government debt be allowed to auction even lower, at negative absolute interest rates. ==Derivatives==
