1914 - 1918
First World War
World War I (1914–1918) profoundly disrupted Europe, causing massive human and material losses. However, its economic consequences were also deep and lasting. Major transformations affected demographics, the role of the state, productive structures, the monetary system, and international relations.
A Lasting Demographic and Health Shock
The war resulted in the deaths of over 10 million soldiers and left millions more wounded, often unable to return to work. This labor shortage severely disrupted European economies. In addition to that, the devastating Spanish flu pandemic (1918–1919) may have caused nearly 30 million deaths worldwide, worsening human casualties. This double catastrophe led to a decline in the working population and in birth rates and increased public health expenditures.
A Strategic State and Resource Mobilizer
Between 1914 and 1918, governments took a central role in the economy to finance and organize the war effort. The state also relied heavily on domestic and foreign loans, such as the American « Liberty Bonds ».
On the international scale, the United States becomes the creditors of Europe as, from their entry into the war in 1917, they grant government loans to the Allies (3 billion dollars to France, 4 billion to the United Kingdom). The repayment of these loans after the return to peace leads to a reversal of financial flows: now capital flows from Europe to the United States. Europe, having exhausted its gold resources during the war, appears over-indebted while the United States benefits from a strong currency and a significant trade surplus.
Monetary Consequences: Inflation and the End of the Gold Standard
The war caused a surge in public spendings. To cope, central banks printed large amounts of money, leading to high inflation. The effects were multiple: loss of purchasing power, rising cost of living, and destabilization of international trade. Countries also suspended the convertibility of their currencies into gold, ending the gold standard, which had ensured monetary stability.
Reparations and the Treaty of Versailles
The Treaty of Versailles (1919) imposed heavy reparations on Germany. This economic burden quickly became a major political issue, fueling financial instability and resentment in Germany. The German government's refusal to accept sole responsibility for the war, combined with the social impact of the economic crisis, fueled nationalist and anti-democratic rhetoric. The perceived humiliation sparked debate about national sovereignty and strengthened far-right discourse, paving the way for authoritarian ideologies. For France, reparations were essential for reconstruction. The 1923 occupation of the Ruhr illustrated France’s determination to secure payments, despite rising international tensions.
Reconstruction and economic recovery in France
The return to peace did not immediately restore pre-war production levels: in France, the industrial production index fell to 57 in 1919 and did not return to its 1913 level until 1924.
The debt associated with financing the war and reconstruction accounted for 52% of public spending.
However, the boom in new industries (automotive, aviation, electrical and mechanical engineering, etc.), the return of the mineral wealth provided by Alsace-Lorraine, and the weakness of the franc, which offset inflation and stimulated exports, enabled France to achieve
economic growth of 5% a year during the 1920s.
