Global Financial Crisis

A French bank could not value assets built from American mortgages, and central banks in three currencies intervened within hours. The episode revealed that the financial system had no national boundaries even though its supervision did.

The Federal Reserve financed a rescue for an investment bank it did not regulate, because the alternative looked worse. Authorities act beyond their formal mandate in a crisis, and the improvisation then becomes the precedent everyone plans around.

The two enterprises held or guaranteed around five trillion dollars of mortgages, much of it owned by foreign central banks including China's. Nationalising them was partly a decision about foreign creditors, and that consideration was explicit at the time.

Lehman was allowed to fail partly because officials judged the political cost of another rescue too high and partly because no buyer could be found. The decision was contested at the time and has been ever since, and its consequences were immediate and global.

An insurance company was rescued the day after an investment bank was not, because its derivatives connected it to every major bank in the world. The distinction was about connectedness rather than size or merit, and it was made overnight.

Congress rejected the programme, markets fell sharply, and Congress passed it four days later. Coercion by market reaction is an unattractive way to legislate, and it is how a great deal of crisis policy is actually made: the legislature was shown the consequence of its own vote and reversed it within the week.

The G7 could not manage a crisis in which China, India and Brazil held the reserves and the growth, so the G20 replaced it as the crisis forum. Institutional membership followed the distribution of economic weight, with a lag of about a decade.

The financial system was stabilised and the employment losses were not reversed for years, which is the distinction that mattered politically. Rescuing the system and restoring the economy are different achievements, and only the first was accomplished quickly.

The crisis began in the largest economy and spread outward through its financial claims, demonstrating that the system's structure was hierarchical rather than flat. Everyone held dollar assets, so a shock at the centre reached everywhere simultaneously.

American authorities acted for a global system because only they could: the dollar's central role made the Federal Reserve the world's effective lender of last resort. That position is the deepest structural fact about the international financial system.

Large holdings of American agency debt by Chinese and other official reserves meant the failure of these firms would have been a geopolitical event. Financial interdependence had created obligations that were not formally sovereign but functioned as though they were.

Within days money markets froze worldwide, trade finance became unavailable and countries with no exposure to American mortgages faced funding crises. The transmission was instantaneous, which showed how integrated the system had become without anyone having decided it should be.

The rescue paid AIG's counterparties in full, including European banks that received tens of billions. American public money flowed to foreign institutions because the system required it and because refusing would have brought down banks whose failure would have returned to American shores within days. It was politically explosive and strategically unavoidable.

The United States could commit seven hundred billion dollars because it borrows in its own currency and its debt is the world's safe asset. States without that privilege faced the same crisis with none of the same options, which is why the outcomes diverged so sharply.

Emerging economies were brought into the management of the system at the moment the incumbents needed their resources and their demand. Inclusion came when it was necessary rather than when it was justified, which is the usual sequence.

China's stimulus sustained global demand and accelerated a shift in economic weight that the crisis had begun. The episode is dated by many analysts as the point at which the unipolar economic order visibly ended, since the state that had caused the crisis was now dependent on the growth of one that had not.

Mortgage lending had been extended to borrowers who could not repay, encouraged by policy, by fee structures and by the belief that house prices only rose. Domestic political preferences about home ownership had built the exposure over a decade.

Rescuing a bank with public money while homeowners were foreclosed created a political resentment that shaped the following decade. Fairness judgments by publics constrain what governments can do next, and this rescue narrowed the options available in September.

Both enterprises were private companies with public purposes and implicit government backing, a hybrid designed by Congress to expand home ownership without appearing on the budget. Institutional fudges of that kind fail in exactly this way.

Congress had refused to authorise support and public opinion was hostile to further rescues, so the political room had closed. Democratic constraint operated exactly as designed and produced an outcome the officials involved regarded as catastrophic.

Bonuses paid at the rescued firm months later produced a political reaction that constrained crisis policy for years. Legitimacy is a resource that crisis managers spend, and this episode exhausted a great deal of it very quickly.

Legislators voted against a measure their leadership and the executive both supported, because their constituents were overwhelmingly opposed. Representation worked exactly as it is designed to work and came close to producing a catastrophe, which is an uncomfortable observation and one that the officials involved have made repeatedly since.

Leaders committed to fiscal stimulus, resisted protectionism and agreed regulatory reforms, and most of the commitments were substantially honoured. Coordinated action among twenty governments is rare and this is among the clearest instances of it working.

Foreclosures, long-term unemployment and stagnant wages persisted while banks recovered, and the perceived unfairness fed populist movements across the democratic world. The political consequences of the crisis have outlasted its economic ones by fifteen years.

The instruments were opaque by construction: securitised, tranched, rated and re-packaged until no holder could see the underlying loans. When valuation became impossible nobody could tell which counterparty was solvent, so lending between banks stopped altogether. Information is the precondition of credit, and the instruments had been engineered in a way that destroyed it.

Saving Bear Stearns established an expectation that large firms would be supported, so counterparties stopped distinguishing between them. The rescue solved an immediate problem and worsened the moral hazard that made the next failure more damaging.

The implicit guarantee had let them borrow cheaply and take risks a purely private firm could not have, and the guarantee then became explicit at enormous cost. Ambiguous backing produces the worst of both arrangements.

No resolution regime existed for a large cross-border investment bank, so the choice was rescue or disorderly bankruptcy with no middle option. Building that mechanism, a way of winding up a large cross-border bank without either a rescue or a collapse, became the central regulatory project of the following decade and is still incomplete for the largest institutions.

Credit default swaps were written by a small London unit with no capital requirement against them, because the contracts were classified as insurance rather than securities. Regulatory classification determined where the risk accumulated, and nobody was watching that category.

The Treasury abandoned the plan to buy troubled assets and injected capital directly instead, following the British model announced days earlier. Policy learning across governments happened within a fortnight, which is unusually fast for anything international, and it happened because officials in both treasuries were talking to each other continuously rather than through formal channels.

The summit trebled the IMF's resources, expanded trade finance and created the Financial Stability Board with a broader membership. Strengthening existing institutions proved far faster than building new ones, and most of what was agreed in London has held, which is a better record than almost any comparable summit before or since.

Basel III, resolution regimes, stress tests and central clearing for derivatives followed, and the banking system entered the 2020 shock far better capitalised. Regulatory reform substantially worked, which is not the conclusion usually drawn from this period, and the contrast with how the banking system behaved under the shock of 2020 is the best available evidence for it.

No forum existed with authority over globally active banks, whose supervision remained national while their balance sheets were not. International society had permitted an activity to outgrow its regulation, and the gap became visible in a single August week.

Central banks coordinated through the Bank for International Settlements and through swap lines opened between them, an informal network doing what no treaty required. Much of what held the system together was arrangements between technicians.

A government took two large financial institutions into public control in order to reassure holders in other countries, without consulting them. Great powers manage systemic risk unilaterally and other states adjust, which is the ordinary pattern.

British authorities blocked the Barclays purchase on the reasonable ground that they could not guarantee obligations of that size, and the two governments had no framework for the decision. Cross-border failure had no rules and improvisation failed.

The failure of a single firm threatened banks on three continents, and no international body had authority over it. That a global exposure could be built with no oversight at all is the crisis's clearest institutional lesson.

Britain's recapitalisation approach was adopted by the United States and then across Europe, a case of a smaller power setting the template in a crisis. Leadership in international economic policy occasionally comes from where capability does not.

A self-selected group of twenty states assumed responsibility for managing the world economy without any formal mandate, and the rest acquiesced. The society of states tolerates directorates when they work, and questions them when they do not.

The crisis was managed cooperatively and the eurozone crisis that followed was not, which suggests the cooperation depended on the shock being shared. International society coordinates when the threat is common and divides when the burden is not.

Risk had been understood as measurable and therefore manageable, an assumption embedded in the models, the ratings and the capital rules. When the assumption failed it did not fail in one place: the models, the ratings and the capital rules had all been built on it, so the entire apparatus for judging safety stopped working simultaneously.

Too big to fail entered general use here, naming a category that then had to be either accepted or legislated against. Once the phrase existed the political problem it described became impossible to leave alone, and every subsequent regulatory reform in Europe and America has been argued about in the terms this expression set.

The word conservatorship was chosen carefully to avoid nationalisation, which was politically unacceptable in the United States. What an action is called determines whether it can be taken, and this one could not have been called what it was.

The failure destroyed the belief that authorities would always intervene, and that belief had been holding the system together. Removing an expectation can be more destabilising than removing an institution, and this is the clearest instance on record.

Derivatives had been understood as instruments that distributed risk and thereby reduced it, an understanding held by regulators and central bankers alike. The crisis showed the risk had been concentrated instead, in places the models did not display.

Bailout became the defining word of the period and the organising grievance of movements on both the political right and left. The meaning attached to the rescues has shaped Western politics more durably than the rescues themselves.

The comparison with 1931, when cooperation failed and the depression deepened, was invoked repeatedly and shaped what leaders felt able to refuse. A shared reading of a historical failure did substantial work in producing agreement.

Confidence in the competence and fairness of financial and political elites did not recover with output, and that loss has structured politics since. What the crisis meant to publics proved more consequential than what it cost them.
