How Do Interest-Rate Changes Affect Currencies, Bonds and Gold?

Interest rates affect the return on holding money and the cost of borrowing, so changes in rates or expectations can influence currencies, bonds and gold. The links are not mechanical. Markets respond to the expected path of rates, inflation, growth and risk, and to whether new information differs from what was already priced in.

For Currencies: Relative Rates and Expectations Matter

If one country's expected interest rates rise relative to another's, its currency may attract more demand, all else being equal. But the relationship is not guaranteed. A rate increase may signal stronger growth, persistent inflation or financial stress, and markets may already have anticipated it. The exchange rate also responds to central-bank guidance, capital flows, trade, risk sentiment and policy credibility.

For Bonds: Prices and Yields Usually Move in Opposite Directions

The market price of a fixed-coupon bond generally moves inversely to its yield. Other things equal, when new-bond yields rise, the fixed cash flows on older bonds become less attractive and their prices may come under pressure. Longer-maturity bonds are usually more sensitive to yield changes, but credit risk, term premium, inflation expectations and supply and demand can alter the result. Changes at different points on the yield curve may reflect differing views about policy, growth and risk; the move in one maturity should not be equated with the direction of all bonds.

For Gold: Real Rates Are Only One Factor

Gold pays no fixed interest, so the opportunity cost of holding it is often compared with real interest rates. Higher real rates may sometimes pressure gold; falling real rates or greater safe-haven demand may support it. However, the US dollar, central-bank purchases, investor positioning, inflation concerns and geopolitical risk also matter. During a risk event, gold may briefly diverge from its usual relationships; liquidity demand can even cause an initial sell-off followed by a later adjustment.

In practice, first write down what is driving the rate move and what the market expected beforehand. Then examine relevant currency differentials, yields at different maturities, inflation expectations and real rates, as well as the dollar and risk sentiment. Explain the market using multiple scenarios rather than a single directional view, and observe sustained changes after an announcement rather than only the initial jump. Expectations may already be priced in, and many factors influence each asset's response.
