Are rising nominal interest rates bullish or bearish for gold?

History tells us that gold bull markets can unfold in parallel with rising or falling nominal interest rates, but this shouldn’t be interpreted as meaning that interest rates don’t affect whether gold is in a bullish or bearish trend. The long-term trend in the nominal interest rate is not critical; what is of great importance, as far as the gold market is concerned, is the REAL interest rate, with low/falling real interest rates being bullish for gold and high/rising real interest rates being bearish.
