Is there a savings glut?
To accurately measure the amount of savings in the economy, we have to look beyond the personal savings rate
Over at Project Syndicate, Barry Eichengreen asks why interest rates have been falling around the Western world for the last 30 years:
However, Eichengreen immediately dismisses the obvious culprit — the idea that there is a savings glut. Interest rates are the price of lending money. If more people want to save than lend, then interest rates will tend to trend lower:
But I think Eichengreen is wrong to dismiss the possibility of a savings glut based on personal savings rates.

Personal savings rates are the difference between personal income after tax and spending. For example, if the equivalent of 95 percent of household income is spent on goods and services, then the personal savings rate is 5 percent.
While this may be good at measuring changes in household saving from year to year, what this doesn’t cover — as Brad DeLong points out — is corporate and business income and saving, as well as money coming into the U.S. from abroad.
And the savings rate doesn’t consider the weight of past savings still sitting in banks, just the level of saving relative to spending in the economy in the last year.
If we want to determine the level of savings in the economy, we should compare the total level of savings with the level of activity in the economy. If we do that — total savings deposits as a percentage of GDP — we see that saving has climbed and climbed. This has been true even though personal saving rates have trended lower and interest rates have remained at zero, which discourages saving:

In other words, savers — which include large corporations sitting on an estimated $2.8 trillion — are not finding spending and investment opportunities for their savings, and the economy is not adjusting very quickly to open up new opportunities for all of that idle cash.
As Brad DeLong says, "[I]f that isn't a "savings glut," what would a savings glut be?
This doesn’t mean that the other things Eichengreen suggests as causes for low interest rates — the damage done to the economy and the labor force during the Great Recession, for example — are not legitimate.
But we should definitely not ignore the reality of the huge and growing quantity of savings in the system.
