1) During this time, the capital borrowed with the motive of industrialisation was rather ploughed in the defence and expansion of the army. This led to a shortfall in the availability of investment for Britain's industries.
2) On the other hand, the factory workers and the farm labourers were moved out of the industries and were made to join the army.
3) At the same time, the war expenses were financed by raising tax rates. As agreed by numerous historians, approximately 35% of the war cost was met via taxes. This left people with a meagre amount of disposable cash and consequently, it led to drastic reduction in the demand for goods in the economy.
4) Wars also led to an acute crisis for necessary goods. This further pushed up the prices of such goods, further worsening the economic situation.
