SAN FRANCISCO (MarketWatch) -- Gold futures added to losses in electronic trading Tuesday after minutes from the Federal Reserve's latest rate-setting meeting showed policymakers less interested in another round of large-scale bond purchases known as quantitative easing. Gold for June delivery GCM22, -0.77% , which had ended the Comex floor session down $7.70 at $1,672 an ounce, fell further in the electronic session. It was recently at $1,648.70, off nearly $31 from the Monday settlement. Investors have bought gold in recent years as a hedge against what they predict will be high inflation as a result of the Fed's stimulus programs.
