Gold would need to rise more than sixfold to top the 1980 record, using a more accurate inflation-adjustment, said John Williams, an economist and the editor of Berkeley, California- based Shadowstats.com. He said the government has understated the cost of living over the past two decades with adjustments in the way it measures the basket of goods and services monitored by the U.S. consumer price index, or CPI. "
“If the methodologies of measuring inflation in 1980 had been kept intact, gold would have to hit $7,150 to be the equivalent of the 1980 record,” Williams said.
