The National Savings Movement was a British mass savings movement that operated between 1916 and 1978 and was used to finance the deficit of government spending over tax revenues.[1] The movement was instrumental during World War II in raising funds to support the war effort. In peacetime the movement provided an easy and safe way for ordinary people to save small sums of money. The movement grew to around 7 million members before ceasing during the 1970s as more modern methods of saving took over. Savings products promoted by the movement typically offered a low level of return but the safety of a government guarantee.
