6.1 There are many ways to measure actual and potential saving. One approach is the household saving ratio as measured in the
National Accounts by subtracting household spending – on goods and services, housing and financial services – from household income, which includes post-tax earnings from employment, benefits and net interest received, as well as imputed sources of income. A lower saving ratio may arise either because of a fall in households’ income, a rise in their expenditure or a combination of the two. As shown in figure 6.1, the savings ratio reached its lowest since the turn of the century at 4.0% in Q1 of 2017. Since then, it changed little before pandemic in 2020 led to a huge spike to 25.9% during Q2 of 2020, when opportunities for spending were rather curtailed. Since then the savings ratio has fallen to 14.3% in Q3 and 16.1% in Q4, still very substantially higher than at any time this century. Latest data for the first six months of 2021 suggest the savings rate remains at about the same level as in the last six months of 2020 and is yet to fall back to pre-pandemic levels.
