The economic insecurity trap

Financial insecurity is self-reinforcing. Setbacks mean reduced planning and saving, and increasing unemployment, income loss and housing costs. Financial vulnerability is persistent and widespread and not limited to people in poverty. Policy-makers need to tackle it.

One finding stands out especially clearly. Differences in savings are associated with larger differences in economic insecurity than any other characteristic we examine. People with high savings report substantially lower insecurity than those with little or no savings. Prior to adjustment for other characteristics, the predicted average insecurity score ranges from a maximum of 68% among those with low or no savings, to 39% among those with high savings.

The message from Figure 1 is straightforward. Economic insecurity reflects the combined effect of people’s financial resources, financial commitments and exposure to risk. It is not confined to those on the lowest incomes, nor is it experienced by everyone on low incomes. Instead, it is concentrated among people whose financial circumstances leave them with limited room to absorb unexpected shocks.

Figure 1 identified the groups most exposed to economic insecurity. The remainder of this report asks a different question: why do people become more — or less — economically insecure over time?

Figure 2 presents this as a simple illustration, but it raises the central question of the report: does this pattern occur repeatedly across thousands of households? Our analysis suggests that it does. Not everyone follows exactly the same path. Many households experience unexpected improvements as well as setbacks. However, the evidence suggests that people who experience insecurity are, on average, more likely to experience circumstances that further reinforce that insecurity. This creates a cycle of economic insecurity.

The idea that disadvantage can become self-reinforcing is well established in research on poverty. People with very limited financial resources often struggle to invest in education, housing or other opportunities that would improve their prospects. Because they possess few financial buffers, unexpected setbacks such as illness, unemployment or rising living costs can have particularly severe consequences.

People who work in insecure jobs, who have more precarious incomes or who live in insecure housing situations are unable to buffer themselves from external events and are therefore at greater risk of falling into and then further into poverty (JRF 2024).5 These processes create what researchers often describe as a ‘poverty trap’. We argue that economic insecurity follows a related — but distinct — pattern.

The key difference is that economic insecurity is not simply about the amount of money people have today. It also reflects uncertainty about tomorrow. The associated concerns, as shown in Figure 1, are broader than just income. Households that feel economically insecure often face uncertain incomes, limited savings and significant financial commitments.

As a result, they are understandably more cautious in their financial decisions. This caution is often entirely rational. Someone with little savings cannot easily risk temporary income loss, invest money that may be needed for essential bills or commit to financial plans whose benefits may only emerge years later. Instead, attention naturally shifts towards managing immediate pressures. Short-term financial planning becomes more important than long-term planning, and maintaining day-to-day stability takes priority over building future financial security.

Paradoxically, however, these sensible responses may also make future insecurity harder to escape. Households unable to save regularly accumulate fewer financial buffers. Without those buffers, future shocks become harder to absorb. Greater exposure to future shocks increases economic insecurity still further. In contrast, households with stronger financial buffers enjoy the opposite dynamic. Savings make unexpected expenses easier to manage. Greater financial stability allows longer-term planning. Longer-term planning makes further saving and investment more achievable.

These households therefore become progressively more resilient to future shocks. The result is 2 contrasting trajectories. For some households, security gradually reinforces itself. For others, insecurity gradually reinforces itself. This report presents evidence that both processes are operating simultaneously.6

Most people, regardless of their financial circumstances, are naturally cautious about taking financial risks. Even among economically secure households, relatively few people actively describe themselves as risk-takers. Nevertheless, there is a clear gradient across the sample. As economic insecurity increases, willingness to take financial risks declines further. The same pattern is visible in long-term planning. Just over half of economically secure respondents say they generally focus on the long term. Among economically insecure respondents, the proportion falls markedly.

These findings are important because they suggest that economic insecurity is associated not only with fewer financial resources, but also with a different financial time horizon and attitude to financial risk-taking. People experiencing insecurity appear to devote more attention to managing immediate pressures and correspondingly less attention to longer-term financial goals. Importantly, these relationships remain even after allowing for differences in income, savings, education, housing tenure, age and a range of other characteristics. In other words, the differences shown in Figure 3 cannot simply be explained by the fact that economically insecure households have lower incomes or fewer assets.

Figure 3 therefore provides the first piece of evidence supporting the idea of an economic insecurity trap. Economic insecurity appears to be associated with financial attitudes that may also make it harder to improve future financial security.

Importantly, this should not be interpreted as an inevitable process affecting every household. Many people experience temporary periods of insecurity before recovering quickly. Others experience unexpected improvements in income or employment that strengthen their financial position. Rather, the model proposes that, across the population as a whole, these relationships tend to reinforce one another. On average, households that begin in a stronger financial position become progressively more resilient, while those that begin in greater insecurity face higher risks of remaining insecure.

The remainder of this report examines whether the evidence supports each stage of this cycle. Specifically, we ask 4 questions:

  1. Do financial setbacks lead to higher economic insecurity?
  2. Do financially insecure households expect more difficult economic futures?
  3. Are those expectations borne out by subsequent experience?
  4. Does insecurity reduce households’ ability to build the financial buffers that would protect them from future shocks?

Taken together, the answers to these questions allow us to fully assess whether economic insecurity genuinely behaves as a self-reinforcing process.

Figure 6 broadens the analysis to a much wider range of life events. Some transitions represent positive developments, such as rising income or increasing savings. Others reflect setbacks, including unemployment or the onset of disability. Figure 6 examines how these different experiences are associated with changes in economic insecurity.

The overall picture is remarkably consistent. Negative changes generally increase economic insecurity. Positive changes generally reduce it. Among the strongest increases in insecurity are those associated with becoming unemployed and becoming disabled. Both represent substantial changes in household finances and future uncertainty, so it is perhaps unsurprising that they have particularly large effects.

Changes in household resources are equally important. People whose household income increases become less economically insecure. The same is true for those whose savings increase. Financial buffers matter independently of income alone. Parenthood is also associated with higher economic insecurity, although the estimate here is more uncertain than for unemployment or changes in income and savings. Becoming a parent often brings both greater financial commitments and greater uncertainty, so some increase in economic insecurity would be expected.

Not every transition produces measurable changes over the period covered by our study. For example, becoming a homeowner is not associated with a statistically reliable change in reported economic insecurity during the 18 months we observe. This does not necessarily imply that housing tenure is unimportant — Figure 1 showed that homeowners generally report lower insecurity — but rather that transitions into homeownership were relatively uncommon during our study period but may influence security over longer time horizons.

Taken together, Figures 5 and 6 demonstrate an important point. Economic insecurity responds systematically to changes in people's financial circumstances. This gives us confidence that our measure captures meaningful changes in people's lives rather than simply reflecting stable differences in outlook or personality.

The pattern is again strikingly consistent. People who report reductions in working hours become more economically insecure. Those who need to borrow for everyday essentials also experience substantial increases in economic insecurity. Using savings to pay routine household bills has a similar effect. Although drawing on savings may be an appropriate response to temporary financial pressure, it also reduces the financial buffer available to a person or their household to cope with future shocks. Housing costs matter too. Households experiencing substantial increases in rent or mortgage payments report higher levels of economic insecurity even after accounting for their previous level of insecurity.

These findings reinforce an important theme running throughout the report. Economic insecurity is shaped not only by major life events but also by the gradual accumulation of financial pressures. For many households, insecurity grows because several relatively modest pressures occur at the same time. Individually, each may appear manageable. Collectively, they substantially weaken financial resilience.

The evidence presented so far points to 3 broad conclusions. First, economic insecurity changes as people’s financial circumstances change. Second, the strongest increases in insecurity follow events that reduce financial resources or increase uncertainty, including unemployment, falling income, declining savings and rising housing costs. Third, even comparatively modest financial pressures — such as reduced working hours or having to draw on savings for everyday expenses — can contribute to rising economic insecurity.

The next question is whether people experiencing higher insecurity also view their future differently — and whether those expectations prove to be accurate.

The contrast is striking. People who feel economically insecure are consistently more pessimistic about the future. They are less likely to believe that their employment prospects will improve. They are less likely to expect their income to increase. They are more likely to anticipate higher housing costs. They are also less confident that they could find another job if necessary or rely on financial support from the welfare system, family or friends. In other words, economically insecure households perceive themselves as having fewer financial buffers and facing greater economic risks.9

While not a surprise, this matters because expectations influence behaviour. Households that anticipate difficult financial circumstances are likely to make different decisions about saving, spending and planning to households expecting greater stability.

We next ask whether these expectations are associated with subsequent changes in economic insecurity. Figure 9 shows that they are.

When people become more optimistic about their future employment prospects, their expected income or the availability of financial support if needed, they subsequently report lower levels of economic insecurity. Conversely, increasing expectations of falling income, worsening employment prospects or rising housing costs are associated with higher economic insecurity. Although these effects are generally smaller than those associated with major life events such as unemployment, they are remarkably consistent.

This highlights an important feature of economic insecurity: it is shaped not only by what has happened, but also by what people believe is likely to happen. Future expectations form part of people’s current experience of financial security. But one important question remains. Are these expectations simply expressions of optimism and pessimism? Or do economically insecure households genuinely face greater future risks?

These findings are particularly important because they move beyond subjective perceptions and indicate that economically insecure households are not merely expecting worse outcomes — they are, on average, genuinely more exposed to them. This helps explain why economic insecurity can become so persistent. People who feel insecure are responding to real vulnerabilities rather than imagined ones. Their expectations are often well founded.

The differences between economically secure and insecure households are substantial. Around half of economically insecure households report having no monthly savings at all. Even among those that do save, the amounts are generally much smaller than among economically secure households. The contrast is equally clear when people are asked about the future. Economically secure households are considerably more likely to believe that they will increase their savings during the coming year. Economically insecure households are much less optimistic. Many believe they are unlikely to save more than they currently do.

These findings are important because they suggest that economic insecurity affects not only current financial resources but also expectations about future financial resilience. The inability to save is therefore not simply another symptom of insecurity. It is also one of the mechanisms through which insecurity persists. Importantly, these relationships are not confined to households living at or below conventional poverty thresholds. Similar patterns are observed among households at the middle-income level and above.11 The economic insecurity trap extends beyond those in poverty.

The findings are reasonably consistent. Households with higher savings subsequently become more economically secure. At the same time, households experiencing greater economic insecurity subsequently save less. In other words, the relationship runs in both directions. Savings strengthen economic security and economic security makes saving easier. Conversely, lower savings increase insecurity, while insecurity itself reduces subsequent saving. This reciprocal relationship is exactly what we would expect if economic insecurity operates as a self-reinforcing process: an economic insecurity trap.

The statistical relationships observed over each 6-month period are individually modest. However, they occur repeatedly. Small differences accumulating over many years can produce large differences in financial resilience. This is precisely how cumulative advantage — and cumulative disadvantage — develop.

After accounting for households’ initial financial circumstances and a wide range of demographic characteristics, people who reported high economic insecurity at the beginning of the study accumulated substantially less additional household savings over the following year than those who initially felt economically secure. The precise estimates vary depending on the statistical model used — from £8,623 to £4,197.12 The central finding does not. Economic insecurity today predicts weaker growth in financial buffers over the long term tomorrow.

We also find that the reduced ability to save among the insecure is not limited to those at the lower end of the income distribution. In Figure A4.3 of the appendix, we re-estimate this analysis, excluding those respondents whose household income puts them below the conventional poverty rate. In this sample, the insecure continue to save less (saving between an estimated £9,104 to £4,508 less, depending on the model), further demonstrating that the insecurity trap is not simply a poverty trap.
