The gold price had a rare week of strong performance, and U.S. real interest rates are the reason why.
The bullion price is highly sensitive to changes in inflation-adjusted (or real) U.S. rates. When real rates are high, the gold price routinely falls. Holding gold is less attractive as an investment if strong inflation-adjusted returns are available in the bond market. (Note: on the chart below, real rates are plotted inversely to better show the trend).
