The market anticipates inflation to move higher next year as COVID-19 vaccines will lead to swift economic recovery. Notably, the 5-year TIPS/Treasury breakeven rate -- a proxy for inflation expectations measured by the yield difference in linkers and regular Treasuries – surged to the highest level since March 2019.The potential vaccines by three firms so far — AstraZeneca AZN, Moderna MRNA and Pfizer PFE — have shown strong effectiveness against the infection in the latest late-stage trial. The UK has already begun rolling out Pfizer vaccines this week, becoming the first country to start vaccinations for COVID-19, while the FDA is set to okay the emergency use of Pfizer/BioNTech's vaccine. Other firms like Sanofi SNY, GlaxoSmithKline GSK, Merck MRK and Johnson & Johnson JNJ are also in the process of developing the vaccine.The vaccine optimism along with rise in some raw materials prices such as copper and lumber will lift inflation. The inflation rate could reach or surpass the Federal Reserve’s 2% target in some months. According to Mizuho International Plc’s Peter Chatwell “a resurgence in global growth in 2021, along with the Federal Reserve’s increased tolerance for inflation, should fuel price pressures and favor securities that protect against cost-of-living increases” (read: Fed Targets "Average Inflation" of 2%: ETF Strategies to Play).The expectation for an uptick in inflation has led to investors’ flocking to Treasury Inflation Protected Securities (TIPS) ETFs. The ultra-popular iShares TIPS Bond ETF TIP pulled in about $1.1 billion capital over the past six days, according to data compiled by Bloomberg. This marks the strongest inflow since early March, before the coronavirus upended financial markets and forced global lockdowns, crushing inflation expectations.Why TIPS ETFs?TIPS ETFs offer shelter against rising inflation. These not only combat increasing prices but also protect income for the long term. To explain in details, consider a fixed interest rate of 2.0% on five-year TIPS with initial face value of $1,000. In the first six months when inflation is zero, the semi-annual interest payment would be $10 but when inflation rises 5% annually in the next six months, the semi-annual interest rate would be $10.25 (1,025*2%-1/2 = 10.25).This is because TIPS pay interest on an inflated-principal amount (principal rises with inflation) and in this case principal becomes $1,025 when the semi-annual inflation is accounted for. As a result, both principal amount and interest payments will keep rising with increasing consumer prices.Given this, investors could bet on TIPS ETFs to combat inflationary pressure in 2021. While there are several options in the space to tap rising consumer prices, we have highlighted five funds that are popular and could be compelling investments (see: all the Inflation-Protected Bond ETFs here):iShares TIPS Bond ETF TIPThis ETF, having AUM of $25.3 billion and average daily volume of 2.4 million shares, tracks the Bloomberg Barclays U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L).
