- When examining debt levels in the UK, there is government debt – measured by public sector borrowing (often referred to as National debt). See: UK National Debt.
- We also have private sector debt which is composed of personal loans, personal mortgages, business debts, and debts of the financial sector.
- You could say total Debt includes both private sector debt plus government debt. Though bear in mind, there is not an exact statistic and it could involve double counting. It is also not measured consistently
- Private sector debt can be split up into
- Household debt – personal loans
- Non-Finance corporates – Company debts
- Financial – debts of banks and financial corporations
Private Sector Debt


Series discontinued after 2017
Government debt

Household + non-financial corporate debt (“private non-financial sector debt”) has in some years reached roughly 150% of GDP.
“Credit provided by the financial sector” (a proxy for financial-sector scale) has, historically, exceeded 200% of GDP during peaks.
Government gross/net debt has at times got close to 100% of GDP
This suggests total debt is around 450% of GDP but that would double-count many internal liabilities (e.g. inter-bank loans, bank deposits, corporate loans from banks, government debt held by financial institutions, etc.). So that “total” isn’t so meaningful
A meaningful “total debt of UK” would require:
- Consolidation across sectors (households, corporates, government, financial institutions)
- Excluding intracountry claims (to avoid double-counting)
- Consistent definition: net vs gross, domestic vs foreign, debt vs liabilities vs credit
Overall, it is worth looking at both government and private sector debt, but to come up with a figure for total debt is hard in a meaningful sense.
Sectoral balances
Another factor worth bearing in mind is link between government deficit and finance/overseas net surplus. If government borrows more, it borrows from private sector or overseas. So the private sector is lending to government, building up assets. Or foreigners are buying UK assets.

Total UK debt

Total UK debt increased sharply in period 1994-2007.
Since 2008, there has been a fall in household debt as a % of GDP – as households cut back debt levels. (note GDP also fell in this period)

Financial sector debt has stayed constant at 200% of GDP.
Main Features
- Total UK debt is 500% of GDP in mid 2012
- The largest component of debt is from the financial sector.
- The deleveraging is greater than may appear from the statistics. Although debt levels have remained flat, this is against the backdrop of falling real incomes.
Compare experience of US – where total debt fell in period 2009-12.

The UK has seen the biggest rise in total UK debt in past 20 years. Only Japan is slightly higher.
Private Sector Debt

Some Notes
- There are big differences between different types of debt, e.g. mortgage debt has low risk of default and is secured against value of asset. In boom years, some of banks debt was highly risky and highly leveraged with little or no security. When credit crisis came, they were short of money and couldn’t get loans bank.
- The high level of debt by UK financial institutions is also a reflection of the size of the finance sector relative to the size of the UK economy.
- Since 2008, UK consumers have reduced debt levels. However, the fall in GDP has meant the decline in debt as a % of GDP has been limited.
- Low interest rates have made debt repayments relatively manageable. But, if interest rates were to rise, it would be more serious.
- Bond yields are low on UK government debt
- The recession led to a big fall in consumer spending as banks and consumers tried to pay off debt, this decline in private sector spending caused an increase in government borrowing. This increase in government borrowing helped to prevent a bigger fall in aggregate demand and more serious recession.
Long Term Impact of High Debt Levels

To improve debt position, consumers try to increase overall savings.
What does this debt mean?
- In the current climate, the high debt overhang, will curtail investment and spending. As firms, banks and consumers try to improve their debt position, it will lead to lower demand in the economy. This is exacerbated by government spending cuts as it tries to improve its own fiscal position.
- International comparisons are not everything. UK and Japan have the highest total debt levels, but they are not facing higher bond yields like in Italy and Spain.
- The size of the financial sector inflates the UK total debt, and it should be remembered it is important to compare to assets. But, high debt levels are significant.
- The high level of debt is one reason why it has been so difficult to get out of recession. It bears all the hallmarks of a balance sheet recession.
- The policy of quantitative easing has helped to a limited extent offset the fall in private sector spending. However, it monetary policy has been fairly limited.
- To a small extent, Inflation in the UK has also been ‘inflating away our debts‘

Many thanks very useful. I am particularly interested by the private sector deleveraging since 2021; largely the result of the inflation component in nominal gdp. Achieving this without a recession is remarkable. After 2-3 more years of 5% wage growth, the debtors in the private sector will be largely recapitalised and a necessary pre-requisite for “real” growth will be restored with no help from politics. Government will deleverage a bit but more slowly because their deficits are large and a decent proportion of their liabilities and promises are indexed, albeit fiscal drag will be helpful, as we saw last week. It is said inflation happens when no group in society will take its share of responsibility for what has happened. The worry has to be that policy makers don’t even begin to look at our problems through this lens and will blow the multiple opportunities presented.
Id like see see uk debt broken down I. Detail by each uk country. We never see any results for england .
The Weimar government of Interwar Germany saw debt levels of 900% of GDP and look what happened to that! I can’t find any examples of high debt levels being reduced short of a financial collapse.
Yes 900% of GDP is high, but, at 70%, the UK still has someway to go to meet Weimar.
The UK reached over 200% of GDP in early 1950s, but it was reduced during the longest period of economic expansion on record.
