Introduction to U.S. Economy: Personal Saving


Personal saving, which includes the saving of households
but not of businesses or government, can have a significant
impact at both the individual and economy-wide levels in
the long and short terms. Recent trends in personal saving,
specifically during the Coronavirus Disease 2019 (COVID-
19) pandemic, have shown notable increases in the personal
saving rate.


The saving rate, which is the ratio of total personal saving
to disposable income, presents a tradeoff between current
and future consumption. A relatively low saving rate
implies higher current consumption but lower future
consumption. Greater present consumption boosts
individuals' living standards now; however, it leaves little
to be invested in capital projects that will boost future living
standards. Conversely, a relatively high saving rate implies
lower current consumption but higher future consumption.
This tradeoff has implications for both short-term and long-
term economic growth.


In the short term, a rising personal saving rate can
temporarily slow economic activity, assuming no other
changes to income. If on average individuals begin saving a
larger portion of their paychecks, it means less money is
being spent on consumer goods and services in the
economy.  Because consumer spending makes up about 70%
of the U.S. economy, even a small decrease in consumer
spending can reduce aggregate demand and economic
activity. Alternatively, a falling saving rate may result in
temporarily faster economic growth as individuals spend a
larger portion of their pay on goods and services.

Whether  changes in the saving rate are helpful or harmful in
the short run depend on the state of the economy. A rise in
the saving rate during an economic downturn can be
problematic. In response to a recession, individuals may
rationally respond to increased uncertainty about their
future income by increasing their saving rate to provide a
buffer against reduced income (caused by job loss, for
example) in the near future. As a result, however, the
economic  downturn is further exacerbated due to the
additional decrease in consumer spending resulting from
the rising saving rate. By contrast, in the midst of a healthy
and expanding economy,  a rising saving rate may result in a
more sustainable level of consumer spending, thus
preventing the economy from overheating. An overheating
economy  occurs when demand  for goods and services
exceeds the economy's ability to produce those goods and
services, which can result in accelerating inflation followed
by a recession.


In the long term, a higher saving rate will generally lead to
higher levels of economic output, up to a point. When
individuals save a portion of their income, those savings are
generally loaned to businesses to finance new investments.
For example, an individual's 401(k) is a saving vehicle for
their future consumption after retirement, but before
retirement, those funds are generally invested in various
companies through the purchase of stocks and bonds.

The overall level of investment is one of the main
determinants of long-term economic growth. Business
investments in physical capital (i.e., machinery, buildings,
and factories) allow the economy to produce more goods
and services with the same amount of labor or raw
materials, increasing the productive capacity of the
economy.  As personal saving contributes to investment, all
else equal, a higher saving rate will result in a higher level
of physical capital over time, allowing the economy to
produce more goods and services. For further information
on business investment, refer to CRS In Focus IF 11020,

H  ow  Is Pers  ona Saving Measured`
The Bureau of Economic  Analysis (BEA) measures the
U.S. personal saving rate (see Figure 1) as the difference
between aggregate income and consumption spending,
which likely introduces some measurement error. The
saving rate may understate the level of saving in the
economy  because certain spending is considered
consumption, even though such spending is conventionally
thought of as investment, such as spending on durable
consumer  goods (e.g., automobiles, appliances).
Additionally, BEA does not include changes in asset prices
or capital gains as income under the saving rate measure.
