Household spending makes up about two-thirds of aggregate demand in the UK. Understanding its determinants is therefore important to understanding short-term economic growth. The real value of consumer spending by British households has risen in each quarter since 2011 Q4. Over the same period real disposable income has flat-lined. This suggests that the British household sector has stepped up attempts to smooth their longer-term spending profile despite the current absence of growth in their real incomes.
When viewed over many years, disposable income and consumer spending grow at very similar rates. After stripping out inflation we find that over the past 50 years both have grown at about 2½ per cent per annum. However, if we measure growth from one quarter of the year to the next we tend to find that consumption growth is less variable than disposable income. This is known as consumption smoothing.
Chart 1 shows the quarterly percentage change in consumption and disposable income since 1998. (Click here to download a PowerPoint of the chart).The variability in the disposable income series is generally greater than that in consumption so helping to illustrate consumption smoothing.
Consumption smoothing is facilitated by the financial system enabling us to either borrow to supplement our spending or to save to enjoy more spending in the future. The financial system can help households to avoid large variations in their spending over short periods.
Consumption smoothing does not prohibit falls in consumption nor periods when it is more variable than income. Over the period from 2008 Q1 to 2011 Q3, real consumption typically fell by 0.4 per cent each quarter while disposable income was flat. This was a period when the global financial system was in distress. Sharp contractions in credit meant that the financial system was no longer able to support economic activity as it had previously. Furthermore, households too looked to repair their balance sheets with economic uncertainty acting as an incentive to do so.
What is interesting is the extent to which British households are spending again. Since 2011 Q4 the real value of spending has typically expanded by 0.4 per cent each quarter while income growth remains largely absent. One might argue that this just demonstrates a willingness for households to engage in consumption smoothing. With credit conditions still tight, the growth in spending has been aided by a decline in the saving ratio. 
This can be seen from Chart 2.
In 2009 Q2 the proportion of income saved hit 8.6 per cent having been as low as 0.2 per cent in 2008 Q1. In 2013 Q1 the saving ratio had fallen back to 4.2 per cent. (Click here to download a PowerPoint of the chart.)
It is of course all too easy to over-interpret data. Nonetheless, there be will concern if households look to maintain consumption growth at rates substantially greater than those in disposable income for too long a period of time. Consumption smoothing could become a real problem for future economic activity if it was to result in a financially distressed household sector. Hence, an important question is the extent to which current rates of consumption growth are sustainable. Future consumption and income trends will therefore be analysed with enormous interest.

Housing Equity Withdrawal, or HEW for short, is new borrowing that is secured against property which is not reinvested in the housing market. In other words, it is borrowed money that is not used by households to purchase property or to undertake major refurbishments, such as extensions to existing residential properties. The latest HEW statistical release from the Bank of England shows that HEW in Q4 2009 was again negative, making it the seventh consecutive quarter of negative HEW. But, what does a negative HEW figure mean?
Negative HEW occurs when the total saving by households in housing (either by paying back mortgages or by purchasing property directly without borrowing) is greater than new borrowing secured against housing. It results in an increase in housing equity held by the household sector. In the fourth quarter of 2009, the Bank’s seasonally-adjusted figures show that negative HEW was just over £4.3 billion, equivalent to 1.6% of disposable income.
But why might the household sector have wanted to save through housing and how might this impact on consumer spending? In truth there is no single reason, but one potentially important reason is likely to be the sector’s desire to rebuild its balance sheets. In times of uncertainty, such as those that we face now, a perfectly understandable response by households is to try to reduce their exposure to debt. During the seven quarters in which HEW has been negative, households have used housing as a vehicle for saving to the tune of £36.5 billion, equivalent to 2.2% of the sector’s disposable income. To some extent the fact that, as a result of the banking crisis, house-buyers have had to put down larger deposits when purchasing housing helps to reduce their exposure to debt. But, the extent of the negativity of HEW means that households more generally have been actively looking to repay some of their outstanding mortgage debt.
So what of the impact of HEW on consumer spending? Negative sums of HEW mean that consumers are either reducing consumer spending, reducing holdings of financial assets, increasing levels of unsecured debt (e.g. personal loans or credit card debt) or, of course, undertaking some combination of these. Given that the stock of unsecured debt has actually declined by £7.9 billion to £224.8 billion in the 12 months to February, the impact would seem to be falling on consumer spending.
Some commentators are pointing to the weakening pace with which households are saving through housing. The current level of saving through housing is, as we said earlier, equivalent to 1.6% of disposable income, down from the 3.0% recorded in both Q4 2008 and Q1 2009. But, this would seem to simply highlight the extent of the precautionary behaviour by households in the midst of the economic downturn. It would be a surprise to see any significant end soon to the UK household sector’s precautionary behaviour.

Housing equity withdrawal (HEW) statistical releases Bank of England
Questions
- Explain what are meant by positive and negative values of HEW.
- What implications might additions to housing equity have for consumer spending?
- What factors do you think lie behind the seven consecutive quarters of negative HEW?
- If house price inflation were to start picking up in the near future, would you expect to see positive values of HEW and, if so, how strongly positive?
- Other than through HEW, how might the housing and mortgage markets impact on consumer spending?
Figures released by the Bank of England show that in the third quarter of 2009 UK households increased their housing equity (i.e. repaid mortgage debt) by £4.9 billion, equivalent to 2% of their disposable income. This was the sixth consecutive quarter in which saving in housing exceeded net mortgage lending. Interestingly, during each of these six quarters the UK economy contracted.
Saving in housing (or ‘negative housing equity withdrawal’ (HEW)) will reduce aggregate demand if it is funded out of income that would otherwise have been spent on consumer goods and services. Since the proportion of income saved, as measured by the saving ratio, climbed from an historic low of 0.9% in the third quarter of 2008 to 8.6% in the same quarter of 2009, increased saving in housing equity has been depressing spending levels. Indeed, across the six quarters in which HEW has been negative, households have increased their stock of housing equity by £33.9 billion, equivalent to 2.3% of disposable income – money which could otherwise have been spent.
Increased saving in housing by households is an example of the household sector’s attempt to repair its balance sheets. Another example has been the fall in the sector’s outstanding stock of unsecured debt (e.g. outstanding personal loans and credit-card debt). Elsewhere in the economy, banks too have been looking to repair their badly damaged balance sheets and, of course, there is the considerable interest in how the UK government will reduce its budget deficit. We can expect these repairs to balance sheets to have some impact on the pace of economic recovery. What is less certain is the size and duration of these balance sheet effects.

Questions
- What factors might explain why UK households have been increasing their saving in housing equity during 2009?
- Why might increasing amounts of HEW, such as those in the mid 2000s, not necessarily result in higher levels of consumer spending?
- What do you understand by the ‘household balance sheets’? What do you think is likely to be the most significant item on the sector’s balance sheets?
Household spending makes up about two-thirds of aggregate demand in the UK. Understanding its determinants is therefore important to understanding short-term economic growth.
