RESEARCH Household Cash Buffer Management from the Great Recession through COVID-19


Cash balances are a linchpin of household financial health. Maintaining a sufficient level of liquidity—which varies with spending needs—allows households to manage spending through short-run changes to income. Over time, savings in the form of cash can also be used for large expenditures or wealth-building investments. The dynamics of checking account balances therefore reflect both consequences of external shocks affecting consumers—e.g., job loss, fiscal stimulus, or unexpected expenses—as well decisions of when and how to save.

COVID-19 brought economic volatility that led to historic swings in the savings rate from a record high in 2020 to very low levels last year before rising steadily in recent months, reflected in trends in cash balances seen in the most recent JPMorgan Chase Institute Household Pulse report. In addition to measuring cash liquidity over a longer time horizon, this report analyzes within-household cash management behavior to help make sense of recent fluctuations. We use a sample of de-identified data covering 19 million individuals from 2008 through early 2023.

Our focus is on cash buffers (liquid balances scaled to expenses), interpreted as the amount of time a person could continue their rate of spending without receiving inflows or accessing new credit. The research questions we target in this report are:

  1. How have median cash buffer levels evolved for different segments of the U.S. adult population since the Great Recession?
  2. To what degree does individual-level liquidity tend toward a stable level over time? How fast does liquidity converge to this average following shocks?

A central finding of this report is the relative stability in cash buffers for over a decade prior to the surge in balances during the pandemic. From 2008 to 2019—a period over which the unemployment rate swung from as high as 10 percent to under 4 percent—median cash buffers stayed within a range of just a few days’ worth of spending.1 While we also find that many individuals frequently experience large swings in liquidity, these idiosyncratic surges and dips do not normally last very long. This is because individuals tend to spend in excess of income when cash buffers are temporarily elevated and vice versa.2

The ongoing decline in the stock of cash balances that were built up in the pandemic is qualitatively consistent with pre-pandemic patterns, although the drawdown has been somewhat slower than usual, according to our estimates.

We organize the analysis around four findings:

Finding One: Across the income distribution, median cash buffers were largely stable from the Great Recession until just prior to the COVID-19 surge in savings.

Individuals with lower average incomes tend to hold lower amounts in liquid balances relative to spending, otherwise referred to throughout as cash buffer.3 Over our sample window from 2008 through early 2023, median cash buffers for the bottom income quartile averaged about half that of the top income quartile. Both the overall level of median cash buffers and gaps across income quartiles were roughly stable prior to the pandemic.

COVID-19 led to a temporary decline in spending starting in March 2020 followed by a rise in income growth fueled by fiscal stimulus, leading to a surge in cash buffers that was more pronounced in percentage terms for lower-income individuals.4 These effects on income had largely dissipated by the end of last year for most people while spending has remained robust, on balance, resulting in the current trend of declining cash liquidity towards the levels observed from 2008 to 2019 across groups, albeit at somewhat varying speeds. In Finding 4 we leverage the dynamics of individual-level cash buffers to help make sense of the trend of “normalizing” household liquidity.

Figure 1: Cash buffers and gaps across income groups were stable before the pandemic-era fluctuations.

We track the median level of cash buffers using a regression-based framework. This helps minimize the effect of changing composition of our sample over time, but it means that our figures for median cash buffer are ‘estimates,’ as opposed to directly measured median values. Appendix A provides details on the approach. An assumption we make in Figure 1 is that the relevant rate of a person’s spending is their trailing 12-months’ median outflows excluding account transfers. We show an analogue to Figure 1 that instead computes cash buffer by dividing liquid balances by the current month’s outflows excluding transfers. Due to sharp changes in spending in 2020 and 2021—e.g., declining around the onset of the pandemic, then surging in the wake of fiscal stimulus—the contours of cash buffers over that period differ somewhat across the two methods for cash buffers. Moreover, since both spending and cash balances exhibit seasonality, the calendar year pattern of cash buffers also changes with the methodology. 

Finding Two: Black and Hispanic individuals hold cash buffers substantially below White and Asian individuals, and disparities did not diminish despite higher income growth of Black and Hispanic individuals just prior to and during the pandemic.

Black and Hispanic individuals experienced relative income gains as the unemployment rate reached historically low levels in the years preceding the pandemic.5 Moreover, fiscal supports provided a more pronounced boost to Black and Hispanic individuals’ incomes during 2020 and 2021. Despite relative income gains in recent years, racial disparities in cash buffers in our data did not diminish.6 To analyze these differences, we rely on a subsample of 1.4 million individuals for whom we have self-reported race data.7

Figure 2: Racial gaps in cash buffers persist, despite relative income gains of Black and Hispanic individuals in recent years. 

Early in the recovery from the Great Recession, Black and Hispanic individuals’ income growth was similar to that of White individuals.8 As the labor market subsequently tightened, income growth for Black and Hispanic individuals began exceeding both Asian and White individuals by about 1 percentage point per year, over from 2017 to 2019. These relative gains extended during 2020 and 2021—due to the impact of Unemployment Insurance and Economic Impact Payments—but the boost to incomes was short-lived.

Liquidity by race directionally tracked income growth in the pandemic. Black and Hispanic individuals saw the largest percent rise in cash buffers at the pandemic peak relative to the 2019 average. However, those liquidity gains were smaller when measured in dollars relative to White and Asian individuals, due to Black and Hispanic individuals’ lower baseline level of liquidity. Moreover, Black individuals experienced a more rapid reversal of cash buffer gains, leaving a somewhat larger range separating racial groups as of early 2023 compared to the average over the 2010s.9

Finding Three: Individuals’ cash buffers often vary widely month-to-month, and those with lower average incomes are more likely to be living paycheck-to-paycheck.

Even in normal economic conditions, month-to-month changes in individual incomes can be highly volatile, frequently leading to large shifts in cash balances.10 This means that a high degree of individual-level variability underlies the relative stability in median balances across the economy in pre-pandemic data. To shed light on individuals’ experience managing their liquidity, here we examine individual-level variation, leveraging statistics from a subsample of 12 million individuals with at least 5 years of active account history.11 To avoid excess influence of the pandemic, we focus on the period from the Great Recession and the pandemic, 2008 to 2019, for Finding 3.

To quantify volatility in cash buffers, we use two measures that scale month-to-month fluctuations to a person’s usual level of balances. Figure 3 shows the median of these metrics by income quartile. The first measure is the standard deviation of a person’s cash buffer scaled by their average level of cash buffer.12 Another metric based on medians—the scaled median deviation from median cash buffer—provides a view of volatility less influenced by outliers.

Figure 3: Volatility in cash buffers over time is substantial at the individual level and is somewhat higher—when scaled to a person’s level of liquidity—for lower-income individuals.

Both metrics depicted in Figure 3 imply substantial variation over time in household liquidity. Using the first measure, typical variation in cash buffers is equal to 80 to 100 percent of a person’s usual cash buffer level. The influence of large, but infrequent, shocks to cash balances has a more substantial effect on the first measure, which is somewhat higher than the second metric.13 For a sense of scale, the 12-month average level of median cash buffers moved up to a peak of 22 days from 13 (70 percent increase) for the first income quartile and to 44 from 28 (60 percent increase) for the top quartile, coinciding with the largest increase in the personal savings rate since World War II. From this perspective, the typical level of variation in liquidity is substantial at the individual level.

Spikes in liquidity provide opportunities for wealth-building as well as spending to satisfy unmet needs. To analyze differential responses to increases in cash buffers due to positive income shocks, we provide a supplemental analysis of how people use funds in the month of a large increase in income in Appendix B. When filtering to events in which monthly income was between 2.5 to 12 times a person’s trailing average level of income, less than half of the abnormal inflow remain in individual’s checking accounts by the end of the month it is received, on average, across income quartiles. Differences by income group in the deployment of funds are consistent with prior findings of the higher tendency of lower income individuals to consume out of temporary gains, while those with higher incomes are more likely to transfer excess funds to savings vehicles like investment accounts.14

On the other hand, dips in cash buffers can indicate financial distress, although the presence of liquid assets not captured in our data may dampen such an interpretation. Figure 4 shows the share of individuals that have less than 7 days’ worth of spending in liquid balances along with the portion of those people with investment accounts to provide a perspective on why such metrics should be interpreted with care.15 Because the highest income quartile is the most likely to have other liquid assets outside of our data set, looking solely at cash buffer metrics understates disparities in financial vulnerability across the income distribution.

Figure 4: Individuals with lower average incomes are more likely to have under one week’s worth of spending in liquid balances and are less likely to have stores of liquidity outside of cash-like accounts.

Individuals in the first income quartile are almost twice as likely to have less than 7 days’ worth of spending in liquid balances relative to those in the top income quartile. Even though cash buffers have been falling from their peak in 2021, the share of individuals with under 7 days’ worth of spending in cash-like accounts in our data remained modestly below pre-pandemic standards through the first quarter of this year. We do not view these metrics as precise indicators of the share of individuals facing financial distress; as noted earlier, these figures almost certainly underestimate disparities, due to the greater share of high-income individuals that have other stores of liquid wealth not captured in these data. 

Finding Four: Individuals gravitate towards a relatively stable personal “normal” level of cash buffers over time, and the decline in overall household liquidity since the pandemic peak has followed a pattern seen in earlier data in individual-level dynamics.

To help make sense of the recent decline in median cash buffers towards pre-pandemic norms, we look at individual-level data on the evolution of cash buffers when balances deviate from normal. Informed by the pre-pandemic stability in cash buffers, our hypothesis is that individuals adjust spending and other behavior to manage their cash buffer to some typical level following shocks. We find a consistent pattern of individuals managing towards levels of cash buffer they maintained previously. When an individual’s cash buffer is abnormally high—i.e., above their trailing baseline—they spend down or transfer excess liquidity and vice versa. Outside of the savings surge of 2020-21, the pace of individual-level normalization has been surprisingly consistent with pre-pandemic experience.

Figure 5 depicts how individuals’ savings behavior (defined as changes in cash balances, scaled to spending) varies depending on a person’s level of cash buffer relative to a prior norm. Here, we use a 36-month lagged value of a person’s cash buffer as the baseline. In addition to helping remove seasonality, this view allows for a consistent methodology for comparing liquidity normalization observed over the course of last year against prior periods. Before COVID, the median individual reached a savings rate of zero (in terms of changes in cash balances) when they had one more cash buffer day than they had 36 months prior. In the pandemic years of 2020 and 2021, individuals had shifted their savings behavior—individuals with a buffer of about two and a half days were neither increasing nor decreasing their cash balances at the median. By 2022, individuals were reaching a stable level of cash buffers a single day above the level observed three years prior, as they had before the pandemic. At a cash buffer level one week above baseline (+7 days on the plot), the median savings rate is -8 percent, implying a decline in excess cash buffer of 2 days. This pace of declines moderates as individuals approach their prior “normal.”

Figure 5: Cash balances evolve asymmetrically, as building liquidity usually takes longer than spending it down.

Figure 6: The dynamics of individuals’ cash buffers since early 2022 has closely followed the pattern seen in general variation in liquidity observed prior to the pandemic.

How we quantify a person’s baseline liquidity and cash savings rate

The analysis underlying Figures 5 through 7 is based on three elements: (1) a person’s cash buffer; (2) an estimate of a person’s past “normal” cash buffer; and (3) a savings rate out of take-home pay. We use the same cash buffer concept used earlier in this report. For the “normal” cash buffer estimate, we take a person’s cash buffer 36 month’s prior. This allows a view of normalization to a pre-pandemic baseline in data through early 2023. Our results do not shift substantially when altering the lag length or using a trailing window for baseline cash buffer. For someone’s liquidity deviation from normal, we take the difference between the current cash buffer and that baseline. Finally, the savings rate proxy is the next month’s dollar change in cash balances divided by the trailing 12-month median level of outflows ex-transfers.

Liquidity normalization differs somewhat across the income spectrum. Figure 7 depicts the process of cash buffer adjustment by income quartile. While patterns—mean reversion and asymmetry—are qualitatively consistent across groups, we see notable differences in magnitudes that inform how different individuals respond to shocks. When cash balances are 10-days below a personal baseline, the median individual in the fourth income quartile builds buffer days by about the same pace as the lowest quartile. However, reductions of excess cash buffers occur more quickly for lower income individuals. For a cash buffer level 10 days above baseline, the median individual in the top income quartile reduces their cash holdings by 7 percent of income, compared to 10 percent for the bottom quartile. 

Figure 7: Cash buffers decline more quickly for lower income individuals when liquidity is above normal.

While Figures 5 to 7 depict the pattern of cash buffers, the actual transactions that influence those dynamics—e.g., spending and account transfers—contain additional information about how and why household liquidity changes over time. In Appendix B we look at significant income shocks and how they are diffused across liquid balances, spending, and savings or transfers. In a result that informs the dynamics underlying cash buffer normalization shown here—we find that higher income individuals adjust liquidity following a positive income shock by increasing savings-related flows (like transferring funds to investment accounts) and experience comparatively less of an increase in spending.

Finding Five: Conclusion and Implications


The pre-pandemic stability in household liquidity metrics described in this report implies that a relatively wide range of economic factors can lead to the same approximate level of cash balances, when scaled to expenses. Moreover, we observed relatively little net change over time in the liquidity gaps across income quartiles and by race over the sample. By contrast, economic volatility during the pandemic led to historic swings in aggregate measures of liquidity, with median cash buffers almost doubling by the April 2021 peak in the measure. Since then, household liquidity has been normalizing, as cash balances have been receding and nominal expenses rising.

We zoom in on individual-level experiences of shocks to make sense of recent trends. During the savings normalization process in 2022 through early 2023, individual liquidity management patterns have been similar to earlier periods. On balance, people tend to manage their balances towards a level of expense coverage and save or spend their way back to prior averages following shocks. The slowing of the declines in liquidity observed in the Household Pulse—and the faster pace of normalization for lower income individuals—is a consistent pattern seen across varying environments over the past decade with little variation outside of the height of the pandemic. Even so the present economic environment has unique features relevant for household liquidity management—including higher short-term interest rates, changing investment trends, and potential new precautionary savings motives.16 These factors could lead individuals to choose either a higher level of cash buffer—perhaps to guard against uncertainty in inflation or fears about job security in a potential recession—or a lower level—to extract higher interest rates in products other than cash deposits, such as bonds or certificates of deposit.


This report provides insights into household liquidity management relevant for macroeconomic policymakers as well as the design of microeconomic policies, including asset limits. In terms of the macroeconomic outlook, our findings provide a perspective on how the pandemic wave of savings may influence consumer demand in the coming quarters. While no recent U.S. precedent exists for an aggregate savings shock of the magnitude seen in 2020 and 2021, patterns documented in this report from idiosyncratic experiences demonstrate a strong tendency for even substantial shocks to dissipate and for cash buffers to gravitate towards the pre-shock level, all else equal. The pattern seen in cash buffers—both in the aggregate and individual-levels—since the pandemic peak is consistent with pre-pandemic behavior.

Gauging financial health implications of individual-level volatility in cash buffers is challenging. Both the level and variability in cash buffers can be the result of smoothing consumption amid income volatility, which is usually a good sign for well-being. Meanwhile, costly decisions (from a quality-of-life perspective) like foregoing spending to preserve cash would mask potential damage to people’s lives.17

Indeed, households’ preferences and decisions appear to influence liquidity levels strongly, as do events outside of their control. Individuals with lower liquidity tend to spend more out of programs like stimulus payments and safety net programs like Unemployment Insurance. The tendency to consume out of programs may suggest the attractiveness of targeting fiscal support based on liquidity. However, doing so could lead individuals to choose a lower level of cash liquidity, i.e., incenting behavior leading to financial vulnerability. Moreover, due to considerable volatility (at the individual level) in cash buffers, a person approaching a policy threshold may fall in and out of eligibility, with little connection to a steady underlying need. In cases in which policymakers see value in asset limit testing, our research suggests that the dollar values should be scaled to a proportion of consumption spending and emergency savings needs. This would help calibrate the delivery of government support to the level of financial risk facing a family and keeps pace with inflation over time.
