CNBC analysis: Treasury Inflation-Protected Securities (TIPS) are becoming attractive for inflation hedging, with 10-year TIPS yields recently hitting 2.87% (after closing at 2.951% on Oct. 5), levels not seen since November 2008. Analysts suggest commodities and infrastructure funds as additional hedges against persistent inflation, which remains above the Federal Reserve's 2% target, with the September CPI expected at 3.6%.
