Gold’s relentless rally got an added jolt this week from the Federal Reserve’s long-awaited interest-rate cut, but some analysts are beginning to wonder if the pool of potential buyers could begin to run dry.

Gold soared above the $2,600 level on Friday for the first time, extending a rally boosted by bets for further U.S. interest rate cuts, and rising tensions in the Middle East.

Sustained demand from investors is also helping to drive the price uptick and will likely play a role in future price growth. As more investors buy gold to capitalize on its upward price trajectory (or gain access to the many other benefits it offers), the price of gold is likely to climb.
