The US stock market interest rate cut usually has the following impacts on the gold market:

1. **Lower interest rates**: A rate cut means lower borrowing costs, and investors may be more inclined to invest in non-yielding assets like gold, as gold does not pay interest. A low-interest-rate environment typically enhances the appeal of gold.

2. **Weaker US dollar**: A rate cut may lead to a depreciation of the US dollar, as investors may seek other higher-yielding assets. When the dollar weakens, the value of gold as a global reserve asset usually rises.

3. **Inflation expectations**: A rate cut may trigger concerns about inflation, and investors may view gold as a hedge against inflation, thereby increasing demand for gold.

4. **Market uncertainty**: Rate cuts are usually implemented against a backdrop of economic slowdown or increased uncertainty. In such cases, investors may seek safe-haven assets, and demand for gold may rise.

Overall, a US stock market rate cut is likely to have a positive supportive effect on gold prices, but the specific market reaction needs to be analyzed comprehensively in conjunction with other economic indicators and market sentiment.
