Our forecasts of income and expenditure allow us to produce a forecast of sector net lending – the balance of saving and capital spending for each sector. This provides a useful diagnostic on the coherence of the economy forecast. We also construct a forecast of the household balance sheet – the stock of households’ financial assets and liabilities – that is consistent with our forecast of households’ net lending.
Net lending and balance sheets
This Forecast in-depth page has been updated with information available at the time of the March 2026 Economic and fiscal outlook.
Household saving ratio
The household saving ratio is defined in the National Accounts as:

Our forecasts for nominal household consumption and household disposable income are described in the relevant sections of this guide.
The net pension equity adjustment represents the amount added to, or subtracted from, the net equity held by households in funded pension schemes. It equals contributions to funded pension schemes by employees and employers (both imputed and actual), less pension benefits paid out. We generally assume employers’ pension contributions grow in line with wages and salaries. Our forecast for employee pension contributions is largely determined by the gilt rate and closing pension liabilities, consistent with the National Accounts measure of this variable. Where necessary, we will make adjustments to each kind of contributions for the effect of policies, including auto-enrolment. Payments of pension benefits in our forecast grow in line with the relevant age group’s population, plus inflation.
While the household saving ratio forecast mechanically derives from the forecasts of its individual components, the ratio itself provides a useful diagnostic on the wider household income and spending forecasts. The profile of the saving ratio can therefore inform our judgements about household consumption and household disposable income. For this work, we typically consider a measure of the saving ratio that excludes the pension equity adjustment, as this component may be less visible to households (especially the imputed elements) and therefore less relevant for their consumption decisions.
Once we have a forecast for the saving ratio, household net lending is then household saving (the numerator of the saving ratio) less household gross capital formation. This last part is largely nominal household investment, which we forecast using real residential investment, house prices and the consumption deflator.
During the Covid pandemic in 2020, the household saving ratio rose to a record high, as consumer spending fell sharply due to public health restrictions, while government policy supported incomes. The saving ratio has since fallen back but remains elevated compared to pre-pandemic averages. We expect households to keep their saving high in the near term, both as a precaution against shocks and due to higher interest rates. Our forecast for the saving ratio then returns towards longer-run averages in the medium term.
Sector net lending
In the National Accounts framework underpinning our forecast, the income and expenditure of the different sectors of the economy imply a path for each sector’s net lending or borrowing from others. In principle, these sum to zero – for each pound borrowed, there must be a pound lent. In practice, ONS estimates of sector net lending do not sum precisely to zero, reflecting differences between the income and expenditure measures of GDP (the ‘statistical discrepancy’). We typically assume this difference remains broadly flat over the forecast period.
Once we have determined our forecasts for expenditure and income for each sector, this gives a forecast for net lending. Taking each sector in turn:
- Households’net lending position reflects household saving and household investment.
- The rest of worldsector’s net lending position largely follows from the current account.
- The public sectornet lending position comes directly from our forecast of the public finances.
- The corporate sectornet lending position reflects corporate profits and investment. It is treated as a residual in our forecast to ensure that net lending sums to zero across the whole economy. This is consistent with the ONS treatment of this sector in the National Accounts: corporate profits, for example, are often subject to ‘alignment’ adjustments to bring the income measure of GDP into line with the headline estimate. However, even though the net lending position of the corporate sector is reached as a residual, it is consistent with our forecast for corporate profits and corporate expenditure (such as business investment), as these elements are components of aggregate expenditure and aggregate income.
While our sectoral net lending forecasts are the arithmetic consequence of judgements and assumptions elsewhere in the forecast, they do not necessarily mark the end of the forecast process. The profile of each sector’s net lending provides an important overall diagnostic on the coherence of the economic forecast. This can prompt adjustments to the judgements we make about each sector’s income and expenditure in later rounds of the forecast.
During 2020, there were very large movements in sectors’ net lending positions due to the pandemic and the huge fiscal support provided in response. Net borrowing by the Government increased significantly, offset by higher saving (net lending) among the household and corporate sectors. As the effects of the pandemic receded, sectors’ net lending positions have moved back towards pre-pandemic positions.
Household balance sheet
The flow of funds constraint
Our forecast of the household sector balance sheet includes forecasts of assets and liabilities. The balance sheet forecast is ‘stock-flow consistent’: that is, households’ acquisition of assets and liabilities is consistent with their aggregate flows of income and saving. The change in the stock of assets or liabilities then reflects both households’ net acquisition of the relevant asset or liability and, where relevant, revaluation effects.
The household balance sheet is subject to the flow-of-funds constraint, as set out in the National Accounts:

Our forecast for household net lending is the starting point for forecasting the household balance sheet. The assets forecast is split into four elements: deposits, equity, pensions and insurance, and ‘other’ assets. The liabilities forecast is split into secured (i.e. mortgage) debt and unsecured debt. Our forecast starts by establishing a baseline forecast for each of these elements. To ensure consistency between the stock and flow positions of households’ financial accounts, any ‘residual’ between the net lending implied by the flows of saving and the net lending implied by our baseline forecast of the ‘stocks’ is apportioned across the components of the household balance sheet. These adjustments ensure that the household balance sheet forecast is consistent with the net lending path implied by our forecasts of income and expenditure. The following sections set out how we produce our baseline forecast for each element of the household balance sheet.
Household liabilities
- Our forecast for secured (mortgage) debtis composed of a path for borrowing for house purchases, less net repayments and write-offs. We project borrowing for house purchases using our forecasts for house prices, property transactions and an assumption about the loan-to-overall-value ratio. (This is the whole-economy equivalent of the familiar loan-to-value ratio in individual house purchases.) We project net repayments and write-offs using historical trends. Further details of this methodology can be found in Box 3.3 of our November 2016 Economic and fiscal outlook.
- The accumulation of unsecured debt in our forecast follows a relationship with several other variables including consumption, unemployment and property transactions. The forecast also includes an assumption that write-offs are a constant proportion of the stock.
Household assets
- Our forecast for householddeposits is informed by factors including the outlook for household consumption and interest rates.
- Changes in the value of households’ stock ofequity assets reflect both households’ acquisition of equities and revaluations as equity prices fluctuate. We project the net acquisition of equity assets in line with households’ net lending position. Revaluation effects are based on our forecasts for domestic and world equity prices.
- Our forecast for the stock of pension and insurance assetslikewise follows both the accumulation of those assets and revaluation effects. The accumulation of pension assets reflects our forecast for the net flow of pension saving, taken from the net pension equity adjustment in the household saving ratio. We forecast the accumulation of insurance assets using past trends and the rate of insurance premium tax. Revaluation effects use our forecast for domestic and world equity prices, along with long-term interest rates, which are used to discount part of the stock.
- Our forecast of ‘other’ assets, such as households’ debt securities, is informed by recent trends, as well as the outlook for nominal GDP growth.
Household net worth
The difference between the value of households’ financial assets and liabilities gives a value for their financial net worth. We also estimate the value of households’ physical assets (i.e. housing) using our forecasts of the housing stock and house prices. Taking financial net worth and the value of physical assets together, the total gives us a forecast for household net worth.
Boxes
Within each of our key publications we include topical ‘boxes’. These self-contained analyses are unique to this publication and tend to cover recent developments in the economy or public finances that complement the main discussion of our analyses.
