Gold, the ultimate inflation hedge, isn’t much use to investors these days.

Oil is in a bear-market freefall that began in June, spearheading the longest commodity slump in at least a generation. The collapse means that instead of the surge in consumer prices that gold buyers have been expecting for much of the past decade, the U.S. is “disinflating,” according to Bill Gross, who used to run the world’s biggest bond fund.

A gauge of inflation expectations that closely tracks gold is headed for the biggest annual drop since the recession in 2008. While bullion rebounded from a four-year low last month, Goldman Sachs Group Inc. and Societe Generale SA reiterated their bearish outlooks for prices. The metal’s appeal as an alternative asset is fading as the dollar and U.S. equities rally, and as the Federal Reserve moves closer to raising interest rates to keep the economy from overheating.

“Forget inflation -- all of the talk now is about deflation,” Peter Jankovskis, who helps oversee $1.9 billion as co-chief investment officer of Lisle, Illinois-based OakBrook Investments LLC., said Dec. 16. “Obviously, oil prices dropping are adding to deflationary pressures. We may see a rate rise next year, and we could see gold come under pressure as the dollar continues to move higher.”

Even though there’s been little to no inflation over the past six years, investors have been expecting an acceleration after the Fed cut interest rates to zero percent in 2008 to revive growth. Those expectations, tracked by the five-year Treasury break-even rate, helped fuel gold demand and prices, which surged to a record $1,923.70 an ounce in 2011.

Crude-oil futures in New York have tumbled 44 percent this year, dropping below $54 a barrel last week, as global output surged. The five-year break-even rate is down 33 percent this year, the most since 2008. In November, the cost of living fell 0.3 percent, the most since December 2008, government data show, and economists predict the annual gain in consumer prices will slow in 2015 to 1.5 percent from an estimated 1.7 percent this year.
