At its June meeting, the Federal Reserve opted to reduce its monthly mortgage and Treasury bond purchases (or quantitative easing) to $35 billion each month from its previous level of $45 billion. I discussed in a recent Blog post that this action continues the Fed’s shift in monetary policy from “excessively easy” to “easy”; but many wonder if the central bank is moving too slowly.

What do I mean by this? Over the past five and a half years the Fed has put an unprecedented amount of stimulus into the economy, all in an effort to jump start growth in the wake of the Great Recession. As the economy recovers, the question becomes when the Fed should remove that accommodation. Move too soon and they risk stifling growth. Move too slowly and it risks igniting inflation. For bond investors inflation represents a significant market risk, as it generally leads to higher interest rates and declining bond prices.

Over the past few weeks the market’s expectation of short term inflation has been trending up. The consumer price index (CPI) posted a year-over-year change of 2.1% and a month-over-month change of 0.4% in May and we have seen an increase in oil and gold prices, as well as the Fed’s indication that it will continue to slowly withdraw stimulus from the economy. At BlackRock, we think inflation will increase only moderately through the end of the year, though we recognize that many investors are looking to prepare their portfolio for a potential rise in prices.

While we still advocate caution towards Treasury Inflation Protected Securities (TIPS), investors looking to hedge against higher rates that result from inflation may want to consider very short duration. Shorter duration investments have less interest rate risk, and thus less inflation risk. Right now we advocate for very short duration exposures — zero to less than two years. Two potential solutions for building exposure to very short duration within your portfolio include the iShares Short Maturity Bond ETF (NEAR), which has an effective duration of 0.85 years, the iShares 1-3 Year Credit Bond ETF (CSJ) which has an effective duration of 1.9 years. Another consideration is the iShares Floating Rate Bond ETF (FLOT), which has an effective duration of 0.15 years.1

Investors in short duration fixed income should be mindful that their yields will be lower than those of longer duration exposures and that a rise in inflation can still erode their purchasing power. If inflation increases sharply, we will likely see longer term interest rates rise in response. Shorter term rates may not be as impacted, but the realized yield produced by a short duration investment would still be reduced on an inflation adjusted basis. For example, the last time the Fed increased the Fed Funds target rate was from June 2004 to June 2006. The Fed Funds rate rose from 1% to 5.25% over the period and the yields on short duration bonds rose as well. At the same time inflation increased from 3% in March 2006 to 4% range by September 2005. Importantly, short term yields rose in-line with increases in the Fed Funds rate. In this way you can think of short term yields as not being driven by inflation directly, but rather by the Fed’s response to inflation. The bottom line is that, short duration investments can help limit the initial shock of inflation, but the inflation adjusted yield on all investments is still reduced.
