Why would gold buying weaken the dollar?
To buy gold, central banks may sell US dollar-denominated assets like Treasuries, reducing demand for the dollar and putting downward pressure on DXY.
Is the dollar's weakness guaranteed?
No, the impact depends on how central banks fund their purchases. If they use existing dollar reserves without selling new ones, the direct effect may be limited.
What other factors could offset the pressure on DXY?
Stronger US economic data, higher interest rates, or safe-haven flows could support the dollar and counteract the selling pressure from gold buying.
