Although Britain's human losses and territory destruction from the War were far less than those of France, the British economy was in depression/crisis, even at a time of relative prosperity for the rest of the world. Its economy had been restructured to support the war effort, with industries redirected to manufacturing war materials, and they faced a difficult transition back to a peacetime economy, suffering from a huge rise in unemployment, taxes & inflation in the 1st half of the 1920s. Also, the government had borrowed heavily to finance the war, leading to increased public debt which they had to pay by selling their international markets. The coal industry was almost bankrupt as their main income resource, coal, began to fall due to the appearance of new energies: oil & electricity.
By the late 1920s, the economy had stabilised, but the overall situation was disappointing: Britain had fallen behind the US as the leading industrial power. Also, there was a strong economic disparity: the south of England & the Midlands being fairly prosperous, while the the industrial north of England had high rates of unemployment & poverty.
