The opportunity cost of gold
Cash and high-quality bonds can pay interest; physical gold does not. When the expected real return on those alternatives rises, holding gold becomes relatively more expensive.
That relationship is a useful framework, not a trading rule. Credit concerns, currency risk, central-bank buying and changes in positioning can dominate for long periods.
Nominal rates are not real yields
A nominal interest rate says how many currency units are paid. The real yield adjusts for expected inflation. A four per cent yield with expected inflation of three per cent is very different from the same yield with inflation expected at one per cent.
Markets react mainly to new information. If a rate increase was fully anticipated, the announcement may have little effect; a change in future guidance may matter much more.
Policy also moves currencies
Higher expected US rates can strengthen the dollar. That may weigh on the dollar gold quote and simultaneously change the result for euro investors.
For that reason it is useful to examine real yields, currency moves and the local-currency gold price together rather than attributing every move to one central-bank decision.
Markets trade expectations
Gold often moves before a central-bank decision because investors continuously price the likely path of policy and inflation. The surprise relative to those expectations matters more than whether the announced policy rate is simply high or low.
Longer-term real yields can also move differently from the current overnight rate. Looking only at the latest decision can therefore miss the financing alternative that market participants are actually repricing.
How to read rate news
A useful sequence is to check what happened to real bond yields and the dollar, identify what the market had expected, and then consider counterforces such as risk aversion, official-sector demand and physical buying.
‘Rates rose, so gold must fall’ is too certain. A more accurate statement is that higher real yields tend to raise gold’s opportunity cost; the final price depends on the strength of all simultaneous drivers.
