07 — The Financial Crisis and the Age of Quantitative Easing, 2007–2019

The bubble

US mortgage credit expanded alongside rising house prices in the early and mid-2000s. The Federal Reserve set its target federal funds rate at 1% on 25 June 2003 and raised it to 1.25% on 30 June 2004; whether that policy explains a large or small share of the housing boom remains contested. The “global saving glut” was a hypothesis about international capital flows and long-term real interest rates, not a measured amount of Asian saving directly deposited into US mortgages. The 1999 repeal of parts of Glass–Steagall also cannot be assigned a single causal share from the evidence here. FOMC, 25 June 2003; FOMC, 30 June 2004; Federal Reserve History, “The Great Recession and Its Aftermath,” “The Housing Sector”; Bernanke, “The Global Saving Glut,” 2005, introduction and capital-flows section.

The Federal Reserve's historical account says average US home prices more than doubled between 1998 and 2006, and household mortgage debt rose from 61% of GDP in 1998 to 97% in 2006. Those are different measures and periods from “all household debt reached 100% of GDP” or a 2000–06 price index. Risky loans were pooled into private-label securities, some with highly rated tranches; a Financial Crisis Inquiry Commission example shows a structured Citigroup deal with 78% of its value rated triple-A, not that every subprime loan was rated AAA. Basel I assigned a 50% credit-risk weight to qualifying, fully secured residential mortgage loans subject to national prudential criteria, not to every mortgage exposure or every investment bank. The SEC's report on the five supervised investment banks shows gross leverage varied by firm and quarter, so “all five ran at 30 times” is withheld. The BIS reported $58 trillion in outstanding CDS notional at end-December 2007; notional is contract face amount, not the same as net loss exposure. These figures describe different parts of the credit expansion and do not establish one complete cause or an S&L-equivalent mechanism.

The crash (2007–09)

House prices peaked in 2006. In August 2007 BNP Paribas froze three funds because it could not value their subprime holdings, interbank lending seized, and Britain's Northern Rock suffered the first bank run in the country since 1866. Bear Stearns was sold to JPMorgan with Fed support in March 2008; Fannie Mae and Freddie Mac, holding or guaranteeing $5 trillion of mortgages, were nationalised on 7 September; and on 15 September 2008 Lehman Brothers filed the largest bankruptcy in US history ($639 billion). The next day the Fed lent $85 billion to the insurer AIG, whose credit-default-swap book would otherwise have brought down every major bank. Money-market funds "broke the buck," commercial paper stopped, and world trade fell faster than in 1929–30.

The response was the largest state intervention in markets since the war. Congress passed the $700 billion Troubled Asset Relief Program on 3 October 2008 after first rejecting it (the Dow fell 777 points that day). The Fed cut rates to zero on 16 December 2008 — the first time in its history — and opened dollar swap lines with fourteen foreign central banks, lending over $580 billion abroad at the peak, which made the Fed the de facto lender of last resort to the world's dollar system. Britain part-nationalised RBS and Lloyds; Iceland's three banks, ten times its GDP, failed and the country imposed capital controls until 2017; Ireland guaranteed its entire banking system and bankrupted the state. The G20, which had been a finance ministers' forum since 1999, was raised to a leaders' summit in November 2008 and at London in April 2009 committed $1.1 trillion to the IMF and development banks — the first time the emerging economies had a formal seat in managing the world's money. China's 4-trillion-yuan stimulus (about $586 billion, November 2008) pulled commodity exporters out of the recession and made China the engine of world growth for a decade.

Quantitative easing: the invention of a new instrument

With short-term rates near their lower bound, the Federal Reserve purchased longer-term securities to ease financial conditions; the Bank of Japan had used asset purchases earlier. The Fed's first programme, announced in November 2008 and expanded in 2009, purchased about $1.75 trillion of agency mortgage-backed securities, agency debt and Treasuries, according to Federal Reserve History, “The Great Recession”. A central bank pays for an asset purchase by creating reserve balances for a bank. If the seller is a non-bank, that bank also credits the seller with a deposit; if a bank sells its own bond, it swaps one asset for reserves without necessarily creating a new customer deposit at that step. Other central banks used their own asset-purchase programmes under different mandates. This is not the same transaction as a government issuing new debt or a bank making a customer loan. Bank of England, 2014, Figure 3. Follow the four balance-sheet examples.

The size of a reserve balance does not by itself tell us how many new loans banks will make, or how much consumer-price inflation will follow. Bank lending depends on borrower demand, credit risk, capital, liquidity, funding, profitability, regulation and policy rates. Asset purchases can affect yields, asset prices, spending and deposits through several channels; assigning the crisis recovery or later distributional outcomes to QE alone requires more evidence than this chapter supplies. Dollar swap lines were a separate liquidity facility, not the bond-purchase programme. Bank of England, 2014, “Two misconceptions about how QE works”.

The eurozone crisis (2010–15)

The euro's missing pieces — no common bond, no fiscal transfers, no lender of last resort to governments, and a Basel rule that let banks hold any eurozone sovereign's bonds with zero capital — came due in 2010. In October 2009 Greece's new government revealed that the deficit was 12.7% of GDP, not 6%; by May 2010 Greece could not borrow, and the EU and IMF lent €110 billion under austerity conditions, the first of three programmes totalling about €290 billion, the largest sovereign rescue ever. Ireland (November 2010), Portugal (May 2011), Spain's banks (2012) and Cyprus (March 2013, with the first "bail-in" of depositors over €100,000) followed. The European Financial Stability Facility (2010) and then the permanent European Stability Mechanism (2012, €500 billion) were created as a eurozone IMF; the Fiscal Compact treaty (2012) hardened the deficit rules; and a banking union with the ECB as single supervisor (2014) was built. But the crisis only ended when ECB president Mario Draghi said in London on 26 July 2012 that the ECB would do "whatever it takes to preserve the euro" and created the Outright Monetary Transactions programme to buy the bonds of any country under attack — that is, when the central bank finally agreed to be the lender of last resort that Maastricht had forbidden. Greece's economy shrank by 25%, the largest peacetime contraction of a developed economy on record, and in 2015 its voters rejected the creditors' terms in a referendum and its government accepted them anyway. The lesson was the same as the gold standard's in 1931: a fixed exchange rate without a fiscal union transmits deflation and cannot survive a democratic vote against it, unless the central bank is willing to print.

The new rulebook

The Dodd–Frank Act (21 July 2010), 2,300 pages long, was the largest American financial law since the 1930s: it created the Financial Stability Oversight Council and the Consumer Financial Protection Bureau, required central clearing of standardised derivatives, gave regulators power to wind down failing "systemically important" firms, and, in the Volcker Rule, banned banks from proprietary trading. Basel III (agreed December 2010, phased in 2013–19 with a final "endgame" package in 2017) raised bank capital to a minimum of 7% common equity (effectively 10–13% for the largest banks), and added leverage, liquidity and stable-funding ratios. These are separate tests: the standardised credit-risk rule has a conditional 0% weight for specified bullion positions backed by bullion liabilities, while the NSFR assigns physically traded commodities including gold an 85% required-stable-funding factor. Neither makes gold a zero-risk asset or establishes a general penalty for every unallocated claim; application depends on the jurisdiction and the bank's exposure. Basel CRE20.110; NSF30.31(4) and FAQ1. The Financial Stability Board (April 2009) coordinated it all, annual stress tests became routine, and the ratings agencies, which had rated the subprime bonds AAA, were regulated for the first time.

The political consequences

The crisis and the response created the politics of the following decade. Bailouts for banks and austerity for citizens produced the Tea Party (2009) and Occupy Wall Street (2011) in America, Syriza and Podemos in Europe, and a general collapse of trust in institutions. The commodity boom that QE and Chinese stimulus fed — food prices at record highs in 2010–11 — was one trigger of the Arab Spring. Standard & Poor's stripped the United States of its AAA rating on 5 August 2011 after a debt-ceiling standoff. Britain voted to leave the EU on 23 June 2016, and Donald Trump was elected on a platform against trade deals and immigration in November 2016; his first term's tariff war with China (Section 301 tariffs from 2018, answered by Chinese tariffs, ended in a "Phase One" truce in January 2020) was the first breach in the free-trade consensus since 1947 and a preview of 2025.

China and the yuan

China's response to 2008 made it the world's largest economy by purchasing-power parity (2014), the largest trader, the largest holder of reserves and the largest creditor. It began, cautiously, to internationalise its currency: the yuan was unpegged from the dollar in July 2005 and rose 35% by 2014; offshore yuan trading opened in Hong Kong in 2009; the Cross-Border Interbank Payment System (CIPS) launched in October 2015; the IMF added the yuan to the SDR basket in October 2016, the first addition since the euro; and the Asian Infrastructure Investment Bank (2015) and Belt and Road Initiative (2013) offered an alternative to the Bretton Woods institutions. But the surprise devaluation of August 2015, the $1 trillion of capital flight it triggered and the tightening of capital controls that followed showed that China would not accept the openness a reserve currency requires. The yuan's share of world reserves was 2% in 2024.

The end of the cycle (2015–19)

The Fed began raising rates in December 2015 and shrinking its balance sheet in 2017; the "taper tantrum" of 2013, when the mere suggestion of ending QE sent emerging-market currencies tumbling, had shown how dependent the world had become on Fed liquidity. Rates reached 2.5% in 2018; Trump publicly attacked chairman Jerome Powell for raising them, the first open presidential pressure on the Fed since Nixon and Burns. In September 2019 the repo market — where banks borrow overnight against Treasuries — seized, rates spiked to 10%, and the Fed resumed buying bills. The system was still on QE life support when the pandemic arrived.

Key takeaways

The 2008 crisis exposed housing-credit losses, leverage and fragile funding. Central banks responded with distinct tools: rate cuts, emergency lending, cross-border swap lines and asset purchases. A purchase financed with reserves is not a bank loan, government spending or free wealth for banks; its broader effects are contested. The eurozone crisis tested the relationship among common monetary policy, national fiscal decisions and lender-of-last-resort commitments. Dodd–Frank and Basel III changed the regulatory framework, while the political effects of bailouts and austerity require separate evidence rather than a single causal chain.
