Second Quarter 2014 Review and Outlook

by and Lacy Hunt, Hoisington Asset Management

Thirty-year treasury bonds appear to be undervalued based on the tepid growth rate of the U.S. economy. The past four quarters have recorded a nominal "top-line" GDP expansion of only 2.9%, while the bond yield remains close to 3.4%. Knut Wicksell (1851-1926) noted that the natural rate of interest, a level that does not tend to slow or accelerate economic activity, should approximate the growth rate of nominal GDP. Interest rates higher than the top-line growth rate of the economy, which is the case today, would mean that resources from the income stream of the economy would be required to pay for the higher rate of interest, thus slowing the economy. Wicksell preferred to use, not a risk free rate of interest such as thirty-year treasury bonds, but a business rate of interest such as BAA corporates.

Follow up:

As chart one attests, interest rates below nominal GDP growth helps to accelerate economic activity and vice versa. Currently the higher interest rates are retarding economic growth, suggesting the next move in interest rates is lower.

Chart 1

To put the 2.9% change in nominal GDP over the past four quarters in perspective, it is below the entry point of any post-war recession. Even adjusting for inflation the average four-quarter growth rate in real GDP for this recovery is 1.8%, well below the 4.2% average in all of the previous post-war expansions.

Fisher's Equation of Exchange

Slow nominal growth is not surprising to those who recall the American economist Irving Fisher's (1867-1947) equation of exchange that was formulated in 1911. Fisher stated that nominal GDP is equal to money (M) times its turnover or velocity (V), i.e., GDP=M*V. Twelve months ago money (M) was expanding about 7%, and velocity (V) was declining at about a 4% annual rate. If you assume that those trends would remain in place then nominal GDP should have expanded at about 3% over the ensuing twelve months, which is exactly what occurred. Projecting further into 2014, the evidence of a continual lackluster expansion is clear. At the end of June money was expanding at slightly above a 6% annual rate, while velocity has been declining around 3%. Thus, Fisher's formula suggests that another twelve months of a 3% nominal growth rate is more likely than not. With inflation widely expected to rise in the 1.5% to 2.0% range, arithmetic suggests that real GDP in 2014 will expand between 1.0% and 1.5% versus the average output level of 2013. This rate of expansion will translate into a year-over-year growth rate of around 1% by the fourth quarter of 2014. This is akin to pre-recessionary conditions.

An Alternative View of Debt

The perplexing fact is that the growth rate of the economy continues to erode despite six years of cumulative deficits totaling $6.27 trillion and the Federal Reserve's quantitative easing policy which added net $3.63 trillion of treasury and agency securities to their portfolio. Many would assume that such stimulus would be associated with a booming economic environment, not a slowing one.

Readers of our letters are familiar with our long-standing assessment that the cause of slower growth is the overly indebted economy with too much non-productive debt. Rather than repairing its balance sheet by reducing debt, the U.S. economy is starting to increase its leverage. Total debt rose to 349.3% of GDP in the first quarter, up from 343.7% in the third quarter of 2013.

It is possible to cast an increase in debt in positive terms since it suggests that banks and other financial intermediaries are now confident and are lowering credit standards for automobiles, home equity, credit cards and other types of loans. Indeed, the economy gets a temporary boost when participants become more indebted. This conclusion was the essence of the pioneering work by Eugen von Böhm-Bawerk (1851-1914) and Irving Fisher which stated that debt is an increase in current spending (economic expansion) followed by a decline in future spending (economic contraction).

In concert with this view, but pinpointing the negative aspect of debt, contemporary economic research has corroborated the views of Hyman Minsky (1919-1996) and Charles Kindleberger (1910-2003) that debt slows economic growth at higher levels when it is skewed toward the type of borrowing that will not create an income stream sufficient to repay principal and interest.

Scholarly studies using very sophisticated analytical procedures conducted in the U.S. and abroad document the deleterious effects of high debt ratios. However, the use of a balance sheet measure can be criticized in two ways. First, income plays a secondary role, and second, debt ratios are not an integral part of Keynesian economic theory.

We address these two objections by connecting the personal saving rate (PSR) which is at the core of Keynesian economic analysis, and the private debt to GDP ratio that emerges from non-Keynesian approaches. Our research indicates that both the "Non-Keynesian" private debt to GDP ratios, as well as the "Keynesian" PSR, yield equivalent analytical conclusions.

The Personal Saving Rate (PSR) and the Private Debt Linkage

The PSR and the private debt to GDP ratio should be negatively correlated over time. When the PSR rises, consumer income exceeds outlays and taxes. This means that the consumer has the funds to either acquire assets or pay down debt, thus closely linking the balance sheet and income statement. When the PSR (income statement measure) rises, savings (balance sheet measure) increases unless debt (also a balance sheet measure) declines, thus the gap between the Keynesian income statement focus and the non-Keynesian debt ratio focus is bridged.

The PSR and private debt to GDP ratio are, indeed, negatively correlated (Chart 2). The correlation should not, however, be perfect since the corporate sector is included in the private debt to GDP ratio while the PSR measures just the household sector. We used the total private sector debt ratio because the household data was not available in the years leading up to the Great Depression.

Chart 2

The most important conceptual point concerning the divergence of these two series relates to the matter of the forgiveness of debt by the financial sector, which will lower the private debt to GDP ratio but will not raise the PSR. The private debt to GDP ratio fell sharply from the end of the recession in mid-2009 until the fourth quarter of 2013, temporarily converging with a decline in the saving rate. As such, much of the perceived improvement in the consumer sector's financial condition occurred from the efforts of others. The private debt to GDP ratio in the first quarter of 2014 stood at 275.4%, a drop of 52.5 percentage points below the peak during the recession. The PSR in the latest month was only 1.7 percentage points higher than in the worst month of the recession. Importantly, both measures now point in the direction of higher leverage, with the PSR showing a more significant deterioration. From the recession high of 8.1%, the PSR dropped to 4.8% in April 2014.

Historical Record

The most recently available PSR is at low levels relative to the past 114 years and well below the long-term historical average of 8.5% (Chart 3). The PSR averaged 9.4% during the first year of all 22 recessions from 1900 to the present. However this latest reading of 4.8% is about the same as in the first year of the Great Depression and slightly below the 5% reading in the first year of the Great Recession.

In Dr. Martha Olney's (University of California, Berkeley and author of Buy Now, Pay Later) terminology, when the PSR falls households are buying now but will need to pay later. Contrarily, if the PSR rises households are improving their future purchasing power. A review of the historical record leads to two additional empirical conclusions. First, the trend in the PSR matters. A decline in the PSR when it has been falling for a prolonged period of time is more significant than a decline after it has risen. Second, the significance of any quarterly or annual PSR should be judged in terms of its long-term average.

Chart 3

For example, multi-year declines occurred as the economy approached both the Great Recession of 2008 and the Great Depression of 1929. In 1925 the PSR was 9.2%, but by 1929 it had declined by almost half to 4.7%. The PSR offered an equal, and possibly even better, signal as to the excesses of the 1920s than did the private debt to GDP ratio. Both the level of PSR and the trend of its direction are significant meaningful inputs.

John Maynard Keynes (1883-1946) correctly argued that the severity of the Great Depression was due to under-consumption or over-saving. What Keynes failed to note was that the under-consumption of the 1930s was due to over-spending in the second half of the 1920s. In other words, once circumstances have allowed the under-saving event to occur, the net result will be a long period of economic under-performance.

Keynes, along with his most famous American supporter, Alvin Hansen (1887-1975), argued that the U.S. economy would face something he termed "an under-employment equilibrium." They believed the U.S. economy would return to the Great Depression after World War II ended unless the federal government ran large budget deficits to offset weakness in consumer spending. The PSR averaged 23% from 1942 through 1946, and the excessive indebtedness of the 1920s was reversed. Consumers had accumulated savings and were in a position to fuel the post WWII boom. The economy enjoyed great prosperity even though the budget deficit was virtually eliminated. The concerns about the under-employment equilibrium were entirely wrong. In Keynes' defense, the PSR statistics cited above were not known at the time but have been painstakingly created by archival scholars since then.

Implications for 2014-2015

In previous letters we have shown that the largest economies in the world have a higher total debt to GDP today than at the time of the Great Recession in 2008. PSRs also indicate that foreign households are living further above their means than six years ago. According to the OECD, Japan's PSR for 2014 will be 0.6%, virtually unchanged from 2008. The OECD figure is likely to turn out to be very optimistic as the full effects of the April 2014 VAT increase takes effect, and a negative PSR for the year should not be ruled out. In addition, Japan's PSR is considerably below that of the U.S. The Eurozone PSR as a whole is estimated at 7.9%, down 1.5 percentage points from 2008. Thus, in aggregate, the U.S., Japan and Europe are all trying to solve an under-saving problem by creating more under-saving. History indicates this is not a viable path to recovery.

Japan confirms the experience in the United States because their PSR has declined from over 20% in the financial meltdown year of 1989 to today's near zero level. Japan, unlike the U.S. in the 1940s, has moved further away from financial stability. Despite numerous monetary and fiscal policy maneuvers that were described as extremely powerful, the end result was that they have not been successful.

Table 1

U.S. Yields Versus Global Bond Yields

Table one compares ten-year and thirty-year government bond yields in the U.S. and ten major foreign economies. Higher U.S. government bond yields reflect that domestic economic growth has been considerably better than in Europe and Japan, which in turn, mirrors that the U.S. is less indebted. However, the U.S. is now taking on more leverage, indicating that our growth prospects are likely to follow the path of Europe and Japan.

With U.S. rates higher than those of major foreign markets, investors are provided with an additional reason to look favorably on increased investments in the long end of the U.S. treasury market. Additionally, with nominal growth slowing in response to low saving and higher debt we expect that over the next several years U.S. thirty-year bond yields could decline into the range of 1.7% to 2.3%, which is where the thirty-year yields in the Japanese and German economies, respectively, currently stand.
