This Box analyses the impact of interest rate changes on the net interest income of households in the euro area. Between July 2022 and September 2023, the ECB deposit facility rate increased from 0.50% to 4% (see Graph 1). Compared to previous tightening phases in the euro area, the strength and speed of the monetary policy tightening was unprecedented. The ECB started lowering its policy rate again in June 2024, and by April 2025 it stood at 2.25%. Changes in the main policy interest rate directly affect households’ disposable incomes via interest payments and receipts on interest-bearing instruments (see Graph 1). The analysis in this Box examines the dynamics of net interest income for the euro area household sector on aggregate and by income groups. In a context of a high cost of living, the rise in interest rates sparked concerns about the resilience of households, in particular low-income households with outstanding mortgages at flexible interest rates. In fact, household disposable income appears to have hardly been affected by the surge and subsequent fall of interest rates.

Households’ net interest income tends to be negative. Net interest income is the difference between the interest payments households receive on their fixed income financial assets (mostly deposits and bonds), and the interest payments they make on their liabilities, mostly mortgage loans. Households in the euro area on aggregate have a positive net financial asset position, including with regard to interest-bearing instruments. ([1]) However, as the interest rates paid on loans exceed those earned on deposits, households’ net interest income tends to be marginally negative (see Graph 2). In 2024, it stood at around ‑1% of gross household disposable income (GHDI).

Following a decline and subsequent stability in the period leading to and following the global financial crisis, household net interest income turned less negative over 2020-2024. Net interest income (as a % of GHDI) declined in the aftermath of the financial crisis and broadly stabilised thereafter, in an environment of low inflation, low interest rates and gradual household deleveraging. In 2020, net interest income in the euro area turned less negative, as interest receipts bottomed out while interest payments continued to decline. This coincided with a strong increase in households’ savings (due to forced as well as precautionary saving) in the wake of the pandemic. As of 2022, net interest income grew by slightly more than 0.5 pps. of GDHI over 2020-2024 in the euro area, benefitting from the increase in interest rates.
Despite the sharp monetary policy tightening in 2022-23, debt servicing costs and income from savings grew only moderately. In 2022, over half of households’ deposits in the euro area were held as overnight deposits ([2]), which carry relatively low interest rates and are not very responsive to changes in policy rates ([3]). The remaining share of deposits were either redeemable at notice or time deposits with a pre-agreed maturity. The high share of overnight deposits in total deposits, and inertia in portfolio shifts, possibly due to heightened uncertainty, resulted in a limited increase in the overall deposit interest rate, which peaked at just below 1.2% in mid-2024. On the liabilities side, the sensitivity of rates on outstanding loans to policy rate changes has declined over time. ECB data suggest that in 2010, around 40% of the stock of loans to households was due to have an interest rate reset within the next 12 months; by 2024, this proportion had halved. The strong decline in credit flows also contributed to the inertia of the implicit interest rate on the outstanding loan stock.
At the same time, households’ net position on interest-bearing instruments improved. Households’ interest-bearing financial assets contracted from 131% to 124% of GHDI over 2022-24 as a result of high inflation (denominator impact), even if household saving rates remained above their long-term averages. The reduction of the asset stock restrained the impact of higher policy rates on interest receipts. In turn, the stock of loans also declined over 2022-24 from 92% to 83% of GHDI, due to subsiding credit flows (active deleveraging) and high nominal GHDI growth (passive deleveraging). The declining stock of loans cushioned the impact of monetary policy tightening on interest payments and reinforced the improvement in net interest receipts.
The net position on interest-bearing financial instruments varies across income groups. ([4]) Data from the 2020-21 wave of the Household Finance and Consumption Survey (HFCS) ([5]) suggest that most households in the euro area have net positive asset positions when considering both financial and non-financial assets (e.g. real estate). When looking only at interest-bearing instruments, about two-thirds of households still have a positive net position. Almost all households have some savings, but only around 40% of them have outstanding debt, and only 27% have mortgage debt. ([6]) Negative positions on interest-bearing instruments are observed mostly among higher earning households (i.e; households in the two highest income quintiles), who tend to have more debt, especially mortgage debt (see Graph 3a), and less deposits (as % GHDI) as they shift a larger proportion of their wealth into higher-yielding non-interest-bearing financial assets (such as equity and insurance and pension savings) and non-financial assets (not shown in Graph 3). Although interest-bearing assets and liabilities represent a fairly similar share of income across quintiles (see Graph 3a), nominal amounts vary widely (see Graph 3b) — resulting in top earners receiving and paying much more interest overall.

Interest rate increases likely had a negative impact on households in the two upper income quintiles. Assuming that the distribution of deposits and loans across quintiles is unchanged from the one suggested by the 2020-21 HFCS data, and that interest rates on interest-bearing instruments have evolved in a similar manner across quintiles, households in the two highest income quintiles are likely to have been the most negatively affected by interest rate increases. These results should be interpreted with caution, as they rest on strong assumptions. In reality, savings and lending dynamics in the face of economic shocks diverge between income groups. ([7]) Research suggests that richer households are more likely to move their savings into higher-yielding deposit types (e.g. time rather than overnight deposits); and HFCS data suggest that the share of flexible rate mortgages decreases with income, ([8]) which increases exposure to interest rate shocks for low-income households. They also suggest that, conditional on having debt, low-income households have higher debt service burdens as a share of their income. In addition, they tend to own less other (non-interest bearing) assets, which could otherwise act as a buffer in the face of income shocks. At the same time, HFCS data suggest that households with mortgage debt at flexible rates and a debt service burden above 40% of their gross income make up less than 1% of euro area households overall, and less than 2% in the bottom income quintile. The next round of HFCS will allow better insights into dynamics across income groups.
Footnotes
([1]) Interest-bearing instruments considered in this note are deposits and bonds on the assets side, and loans on the liabilities side. They exclude other financial assets (such as equity, pension and insurance savings) and non-financial assets (such as real estate). Households’ financial assets in the euro area are mostly composed of deposits, shares, and insurance/pension guarantees, each making up about one third of all their financial assets in recent years. Over the 2010s, households saw a strong increase in their net financial asset positions, mostly on account of equity and investment fund shares.

([7]) For instance, various studies have suggested that high-income households were more likely than low-income households to see an increase in savings during the COVID-19 pandemic. See e.g. Friz, R., Morice, F. (2021) Will consumers save the EU recovery? Insights from the Commission’s consumer survey.

(2023) COVID-19 effects on income, consumption and savings: evidence from the Luxembourg Household Finance and Consumption Survey. Bulletin BCL 2023/2: 50-59. The Commission’s 2025 Alert Mechanism Report also suggests that saving rates and credit growth have shown heterogeneous patterns across euro area countries over recent years, with the euro area saving rate remaining above its long-term average on aggregate, while countries with already lower saving rates before the pandemic saw a further reduction in saving rates in the face of high inflation.
([8]) The analysis considers the euro area-wide income distribution. Between country differences (e.g. in the use of flexible rate mortgages) are likely to have a stronger impact on the results than within country differences. Within countries, the presented variables may vary differently across income quintiles.
