The objective for many portfolios is to minimize downside risk, which leads many advisors to push for more diversification. However, diversification often translates to a greater number of funds instead of a wider distribution of factor exposures. In this post, OFA will discuss one of the most overlooked types of asset: inflation hedge. We will take a look at this asset type, intuitively, from the perspective of business cycle theory. Then, we will discuss the current macroeconomic environment that warrants the inclusion of this asset type.
The Business Cycle
A business cycle is a fluctuation of economic activity. It describes the change of the demand-side of the economy as measured by GDP. Figure 1 shows the business cycle in the United States since 1965 as measured by the output gap. The output gap is defined as the difference between actual GDP and potential GDP. If the output gap yields a positive number, it is an indication that aggregate growth is outpacing aggregate supply; if the output gap is negative, the reverse holds true.

One way to gauge where the economy is in the business cycle is to observe the actions of the central bank, which is the clearest indicator of economic health. Central banks generally tighten monetary policy when inflation is high/rising and productive capacity is running low. Easing will occur when the reverse conditions exist. The business cycle typically occurs in five phases. Figure 2 below summarizes those phases and each of their respective characteristics. Please note that the figure below depicts a general outline of the business cycle.

Inflation Hedge assets will perform well when the expansion phase of the economy is nearing its end. Investors may ask why they should worry about inflation given where we are in the business cycle. We will now discuss why inflation should be a concern in light of the current economic environment.
Current Macroeconomic Environment
The past 25 years have been characterized by declining interest rates and low, stable inflation (2.70% average annual inflation based on CPI and 2.43% average annual inflation based on PCE). This time period is fresh in many advisors’ experience and acts as a “cognitive primer” of their current asset allocation. However, as past performance may not be an indication of future returns, we believe that the current macroeconomic environment is the start of a secular shift, which will be characterized by a sustained, higher level of average annual inflation, and hence, warrants the inclusion of inflation hedge assets. Furthermore, inflation hedge assets help in overall portfolio diversification.

One interesting characteristic of the macro environment over the last 4 years is that the Federal Reserve’s balance sheet has continued to expand at a time when the deficit is persistently high and the debt overhang is a major concern. Combined with asset purchases by the Fed for the purposes of suppressing interest rates, the current environment left the government with few choices: increase growth (easier said than done) or increase inflation (easier done than said).

Figure 5: Debt as a % of GDP
How likely are the two scenarios? Real economic growth has been stubbornly low. The latest revised GDP report (Q4) came in below expectations at 0.10%. The headline number was dragged down by big declines in defense spending and inventories. Going forward, government spending will likely remain a drag throughout 2013 as rebalancing to the private sector takes place. The Federal Reserve, in their long term outlook, forecasts nominal GDP growth of 5%. PIMCO breaks the Fed’s GDP forecast down by real growth (approximately 3%) and inflation (2% PCE inflation). The Fed’s forecast can be interpreted as pseudo nominal GDP targeting which implies that, absent real economic growth, the Fed will use inflation to achieve their target nominal growth rate. As such, we believe there is a probability of higher inflation in the future.

Conclusion
The case for including, or at least considering including, inflation hedge assets in a portfolio based on the above information is as follows:
- Assuming that it is the intention of the Fed to close the output gap outlined in Figure 1, this can only be done by increasing economic production and/or through inflation. As discussed, economic growth remains stubbornly low both in the U.S. and globally. Inflation, on the other hand, is much easier to induce through monetary policy actions.
- Based on the Fed’s nominal GDP forecast outlined in Figure 6, inflation is going to play a meaningful part in achieving that target.
What is even more interesting to consider, in terms of inflation and GDP, is whether or not the U.S. economy has undergone a structural shift in which 3% real GDP growth per annum is actually achievable.
There are a number of assets that will provide an inflation hedge while also providing different risk/return characteristics. These assets include: inflation linked bonds, commodities, and real estate provide direct inflation hedge protection. Meanwhile, precious metals, currency, and bank loans can also provide some protection.
