The Financial Cost of World War 1

World War I cost more money than any previous war in history. One estimate suggests $186 billion in direct costs and another $151 billion in indirect costs, although the full cost is complex and may never be fully known. The Allies had much more potential wealth they could spend on the war. Another estimate (using 1913 US dollars) is that the Allies spent $147 billion on the war and the Germans and their allies, only $61 billion. Among the Allies, Britain and its Empire spent $47 billion and the U.S. $27 billion (America joined the war in 1917) while among the Central Powers, Germany spent $45 billion.

Before World War One, Britain was the world’s economic superpower. With rapid growth and a vast empire, the country enjoyed significant levels of wealth and resources. However it wasn’t ready for the economic impact war would have.
In contrast, Germany’s 1912 budget had approved rising military expenditure until 1917 – effectively militarising their economy ahead of the conflict.
When war erupted in the summer of 1914, Britain faced market panic and a massive financial crisis. Not only did the government need to reassure the markets, it had to prepare itself for the huge economic demands of total war. Facing the financial strain of war, the government had to find ways of raising money. They had three main economic tools at their disposal:
Although indirect taxes raised some money, the government turned to direct taxes – on property and income – on a far greater scale. In 1913 income tax was only paid by 2% of the population. During the war, another 2.4 million people would end up being eligible so by 1918, 8% were paying income tax.
This took the form of big international loans but also borrowing from the public through the war bonds scheme. Big promotional campaigns were used to inspire the country to invest in the war effort.
Printing money
Freed from the Gold Standard by the Currency and Bank Notes Act of 1914, the Bank of England was able to increase availability of money by printing it, even though this risked contributing to inflation – rising prices.

In the United Kingdom, funding the war had a severe economic cost. From being the world’s largest overseas investor, Britain became one of its biggest debtors with interest payments forming around 40% of all government spending. The economy (in terms of GDP) grew about 7% from 1914 to 1918 despite the absence of so many men in the services; by contrast the German economy shrank 27%. The War saw a decline of civilian consumption, with a major reallocation to munitions. The government share of GDP soared from 8% in 1913 to 38% in 1918 (compared to 50% in 1943).

Inflation more than doubled between 1914 and its peak in 1920, while the value of the Pound Sterling fell by 61.2%. Reparations in the form of free German coal depressed local industry, precipitating the 1926 General Strike. The Versailles Treaty set German repayments for the cost of the war at 132 Billion Marks. This was to be repaid in cash or raw materials, land given up and services provided. These repayments were suspended in 1932, by which point Germany had repaid only 20.5 Billion Marks (about $6 billion).

British private investments abroad were sold, raising £550 million. However, £250 million in new investment also took place during the war. The net financial loss was therefore approximately £300 million; less than two years investment compared to the pre-war average rate and more than replaced by 1928. Material loss was “slight”: the most significant being 40% of the British merchant fleet In sunk by German U-boats. Most of this was replaced in 1918 and all immediately after the war.

Although Britain was ultimately victorious, the effects of war would be felt for many years to come. Foreign trade, a key part of the British economy, had been badly damaged by the war. Countries cut off from the supply of British goods had been forced to build up their own industries, so were no longer reliant on Britain, instead directly competing with her. In 1920/21, Britain would experience the deepest recession in its history.

World War One was a significant moment in the decline of Britain as a world power. It would be gradual, but by the mid-20th century the United States would usurp Britain as the leading global economic power.

Today, nearly £2 billion worth of WW1 War bonds are circulating in the market. War bonds originally paid an interest rate of 5%, but in 1932, as the government battled against a budgetary crisis, the then Chancellor Neville Chamberlain changed the terms of those bonds. He appealed to holders to do their patriotic duty and voluntarily accept a cut in the interest rate to 3.5%. All but a small minority agreed the terms – and that wasn’t their only sacrifice.

War bond holders also agreed in effect to accept that they might never get their investment back. Whereas the original bonds had been due to be repaid in full in 1947, Chamberlain converted them to “perpetuals”, giving the government the right not to pay back the loans if they so wished, as long as they continued paying the 3.5% interest.

Surprise, surprise – no government since the 1930’s has chosen to repay these bonds. There are believed to be about 125,000 holders – some of whom might have inherited them from parents or relatives who bought them during World War One.

The continued existence of the war bond debt is possibly the most graphic illustration of the lasting shadow cast by World War One.

The estimated costs for WW1 for each participating nation are listed below (in US dollars). All the costs of the Great War from 1914 to the present, includeDebt servicing, veterans and survivors benefits, lost human capital and productivity, reconstruction requirements, expenses due to subsequent catastrophes caused by the Great War.

Britain still pays for the First World War. UK Government’s raised £1.7 billion in War Loans between 1914-1919 (about £105 billion in today’s money). In 2015, there were still 11,000 registered holders of these war bonds, who are owed £1.9 billion. Interest payments on these War Bonds costs the United Kingdom £75 million every year.

(Note: a US Dollar in 1918 was worth about $17 dollars today. Also £1 GB Sterling in 1918  = $2.879  US Dollars)
