The Fed may need to act as potential trouble brews in a key corner of the financial market

Yeah, who wants to read about potential troubles in the market and apply some form of analysis and due diligence to said potential problems.
More the question, why did you even read the bloody “stupid” article!

The bottom line is "liquidity conditions are tighter than they've been in recent years, so small shifts in supply and demand can create more visible volatility in money-market rates. That's not unusual, but it feels more dramatic because we've gotten used to extremely stable rates in a world of abundant liquidity."

That’s the problem.

There’s stress in the system

Funding markets, which are designed to ensure a smooth and continuous flow of capital, experienced periodic strains in September, as well as at the end of October and November. Tighter conditions in these markets serve as a warning of reduced liquidity and the potential for broader market disruptions. Concerns now are that liquidity strains may keep coming back despite the end of the Fed's balance-sheet reduction efforts, which should theoretically be injecting more liquidity into markets. The pressure now being seen in funding markets, which coincided with the end of November, suggests that reserves are no longer abundant and "may even be scratching the surface of 'ample,'" said Gennadiy Goldberg, head of U.S. rates strategy at TD Securities in New York. TD sees a rising risk that, in January or potentially even sooner, the Fed will need to announce reserve management purchases - which involve central-bank purchases of Treasury bills as a way to inject more liquidity into the financial system.

yes, its mean time to short selling XAUUSD.

Stupid article: potential troubles constantly brew in all corners of the financial market.
