Great Depression

A stock market fall in one country became a world crisis because that country held most of the world's gold and had become its principal creditor. American capital had been sustaining German reparations and European recovery, and when it stopped, the dependence became visible all at once.

A thousand economists petitioned against it and Congress passed it anyway, because tariffs are made by legislators answering to producers in their districts. Trade policy in this period was a domestic distributive question that happened to have foreign consequences, and the consequences were nobody's responsibility.

France attached political conditions to helping Austria, requiring abandonment of the proposed customs union with Germany, and the delay was fatal. Using a financial rescue as diplomatic leverage was ordinary statecraft, and it converted a bank failure in Vienna into a continental banking crisis.

Exchange controls gave the state command over every foreign transaction, and that machinery was never dismantled. A crisis measure taken by a democratic government in 1931 became an instrument of autarky and rearmament under the next one. Emergency powers outlive the emergencies that justify them.

Britain abandoned a commitment it had defended at enormous cost for six years, and recovered faster than the countries that stayed. The lesson was that the constraint had been self-imposed. States sometimes hold to a policy long past the point of advantage because abandoning it would confess an earlier error.

The most striking foreign-policy fact about the New Deal is how little foreign policy it contained. A government facing twenty-five per cent unemployment turned inward, and the international consequences of American recovery were left to look after themselves. Domestic crisis crowds out everything else.

Sixty-six countries assembled and Roosevelt torpedoed the outcome by telegram, refusing to subordinate American price recovery to currency stabilisation. He judged domestic needs paramount and said so publicly. Conferences fail when the strongest participant concludes that agreement costs more than freedom of action.

The economies that recovered fastest were those spending most on weapons, which gave rearmament an economic constituency alongside a strategic one. Germany and Japan found that military spending solved unemployment, and states rarely abandon a policy that solves two problems at once. Rearmament became self-sustaining.

Britain no longer had the resources to act as the system's stabiliser and the United States was unwilling to, so nobody performed the function. A structure with a vacant hegemonic role has no lender of last resort and no open market for distressed goods, and it amplifies shocks instead of absorbing them.

Retaliation was immediate and general, and world trade fell by roughly two-thirds over three years. In the absence of any power willing to keep its market open regardless, each state's rational protection triggered everyone else's, and the system contracted toward autarky and blocs.

Austria was small and its collapse still transmitted through central Europe, because the region's banks were interlinked and everyone's reserves were tied to the same gold. Interdependence without any shock absorber means a peripheral failure travels to the core, and there was no absorber anywhere.

Germany's exposure was structural: it had financed reparations with short-term American loans, so a withdrawal of foreign credit hit the payments and the banks simultaneously. A state dependent on external finance to meet external obligations has no defence when the finance stops.

The pound's departure split the world into currency blocs: sterling, dollar, gold, and later autarkic zones. Monetary fragmentation followed the same lines as the political one, and by the late 1930s economic blocs and strategic alignments had become substantially the same map.

American recovery mattered to every other state and was pursued without reference to any of them, which is what the strongest unit in a system can afford to do. The devaluation of the dollar in 1933 was a unilateral act with worldwide effects, taken for entirely internal reasons.

Cooperation required the largest economy to accept constraints for the sake of the others, and no mechanism existed to make that worth its while. Absent a state willing to bear the costs of stabilising the system, coordination fails even when every participant knows what the solution is.

Recovery through arms production converts economic revival directly into military capability, and the states doing it were the revisionist ones. The distribution of power shifted through the second half of the 1930s as a byproduct of how each government had chosen to fight the depression.

The immediate policy responses were shaped by domestic electorates demanding protection for their own producers, jobs and savings. Every government acted rationally for its own constituency and the sum of those decisions made all of them poorer, which is the characteristic shape of the interwar economic disaster.

The tariff is the standard example of concentrated interests defeating diffuse ones: each protected industry lobbied hard, consumers and exporters were unorganised, and log-rolling produced a bill nobody had designed. This is a domestic institutional failure with catastrophic international effects.

Creditanstalt had absorbed a failing rival at the government's request two years earlier, taking on losses to prevent a visible failure. Domestic political pressure to avoid a bank collapse had concentrated the risk into one institution, and the rescue was what made the eventual failure systemic.

Brüning governed by emergency decree, cutting wages and benefits into a depression because the Reichstag would not vote the measures. Democratic procedure was suspended to pursue a policy that deepened the slump, and both the suspension and the policy fed the parties promising to end the republic.

Leaving gold was forced partly by a naval mutiny at Invergordon over pay cuts, which convinced markets that Britain could not impose further austerity. Domestic consent set the outer limit of what the government could do, and the limit was discovered by sailors rather than by economists.

Banking reform, deposit insurance, securities regulation, public works and labour rights redefined what a government owed its citizens, and did so through legislation, courts and elections rather than by decree. That contrast with contemporaneous Europe is the New Deal's largest political achievement.

Every delegation arrived with instructions written by a government facing unemployment at home, and none had authority to concede anything that would raise it further. International conferences are constrained by the ratification each delegate must survive on return, which was impossible for all of them at once.

Democracies could not easily match this, because rearmament competed with welfare spending that voters had been promised and could refuse to fund. Authoritarian regimes faced no such contest. The constraint was political rather than economic, and it explains much of the rearmament gap before 1938.

The crash exposed how little machinery existed for handling a cross-border financial shock: no international lender, no coordinated central banking beyond informal contacts, no forum with authority. The absence of institutions did not cause the crisis, but it determined how far and how fast it spread.

American trade policy was reformed four years later by moving tariff-setting from Congress to the executive under negotiating authority, which is the institutional fix. Changing who holds the pen changed the outcome, and every subsequent trade liberalisation rests on that reallocation of power.

The Bank for International Settlements existed and had been created for exactly this kind of coordination, and it could not assemble a credit large enough or fast enough. An institution with the right mandate and inadequate resources fails at the moment it was designed for, which is the worst possible failure.

The Hoover moratorium suspended reparations and war debts for a year, arriving after the panic had begun. Relief that comes late confirms the fear rather than dispelling it. Timing is a substantive feature of financial rescue, not an administrative detail, and everyone involved learned it here.

The gold standard was a rule with no procedure for orderly adjustment: a country in deficit had to deflate until it could not, and then leave. Rules that permit no revision are broken rather than amended, which is precisely the flaw Bretton Woods was designed to correct.

Glass-Steagall, deposit insurance and the securities regulator addressed the information and incentive problems that had produced the collapse: who may take which risks with whose money, and what must be disclosed. These institutions outlasted every particular programme and shaped finance for fifty years.

The conference had no continuing secretariat, no prior technical agreement and no fallback smaller than complete success. Eleven years later Bretton Woods reversed all three: two years of expert negotiation before the meeting, a drafted text, and permanent institutions to administer whatever was agreed.

The Tripartite Agreement was a modest thing, three governments promising to consult on exchange rates and avoid competitive devaluation, and it held. After a decade of failure, cooperation resumed at the smallest workable scale. Institutions often restart from narrow technical agreements rather than comprehensive ones.

Economic management had not yet been accepted as a matter of common concern among states. Sovereignty over money and trade was regarded as absolute, and the idea that a government owed others any consideration in setting them was barely present. That understanding changed because of what followed.

Closing a market this large without consultation was not regarded at the time as a breach of any obligation, because no such obligation existed. The subsequent creation of trade rules reflects a decision that this conduct should become the business of other states, which was a genuine change in the society's rules.

The customs union proposal had been challenged as a violation of Saint-Germain's ban on Anschluss, so a question of legal obligation was entangled with a question of solvency. Treaty terms designed to contain a defeated power obstructed the rescue of one, with results nobody had intended.

The crisis showed that reparations, war debts and private lending formed one chain that no state could cut alone. The recognition that these were common problems requiring common solutions arrived too late for the interwar period and was designed into the arrangements made after 1944.

The pound had been the anchor of an international monetary order, and Britain left it without consultation and with a day's notice to its partners. Even in 1931 that was regarded as a departure from expected conduct among the countries that had trusted the arrangement.

The idea that governments bear responsibility for employment and welfare, rather than merely for order and defence, spread through the industrial world in this decade. That shift in what states are for eventually became an assumption behind the postwar international economic settlement.

The failure showed that the society of states had no accepted procedure for managing the world economy and no agreement that it should try. The subsequent decade of blocs and autarky was the alternative, and it supplied the argument that made the 1944 negotiations possible.

By 1936 the world economy had divided into blocs organised around empires, currencies and autarky, and the assumption of a single trading system had gone. That fragmentation was as much a breakdown in international society as the political crises that accompanied it.

The gold standard was not merely a technical arrangement but a moral one, tied to notions of soundness, honour and civilised finance. Defending it at enormous cost made sense to men who understood it that way, and the belief outlasted the point at which the policy had become destructive.

Smoot-Hawley entered postwar memory as the object lesson that made trade liberalisation politically possible for fifty years. Historians debate how much damage the tariff itself did; what mattered was the meaning assigned to it afterwards by the people building the successor system.

A run is a collective belief that becomes true by being held. Once depositors across central Europe understood that banks might fail, they behaved in ways that made failure certain. Confidence is the substance of banking, and no amount of underlying soundness survives its removal.

Germans experienced this as the second monetary catastrophe in eight years, after the hyperinflation, and the two fused into a single conviction that the republic could not manage money. That belief did more political damage than the unemployment figures, which were worse elsewhere.

Returning to gold in 1925 had been an assertion about Britain's standing as much as an economic policy, and leaving it was experienced as a national humiliation. When a technical arrangement carries the weight of prestige, the decision to abandon it becomes far harder than the economics warrant.

Roosevelt's achievement was substantially about confidence: the fireside chats, the bank holiday, the insistence that fear itself was the enemy. Reopening banks worked because people believed they would stay open. Economic expectations are constituted socially, and he understood that better than his advisers.

The bombshell message ended an era in which international economic cooperation was assumed to mean restoring the prewar order. After 1933 recovery was understood as a national project, and that understanding dominated policy in every major economy until the war forced it open again.

Autarky was not merely an economic policy but a national ideal in Germany, Italy and Japan, presented as self-sufficiency, strength and freedom from foreign dependence. Framed that way it was pursued past the point of economic sense, because the value was independence rather than prosperity.
