Wednesday’s Federal Reserve policy decision was fairly boring for investors — officials kept interest rates the same, just as they have since July 2023.

But some savvy traders are excited about another key decision. The Fed announced that it will significantly curtail its quantitative tightening (QT) program — that’s the selling off of its assets to decrease money supply and increase interest rates — beginning in June.

US Treasury yields fell on the news. Yields on the 10-year and 2-year both dropped by .05 percentage points.

What’s happening: The Fed bought a ton of government-backed bonds between 2020 and 2022 to help support economic recovery after the pandemic-induced recession. Those purchases ended up pushing down interest rates in certain parts of the economy, like housing and auto sales.

In mid-2022, as inflation soared higher, the Fed reversed that and began unloading those bonds.

The Fed currently lets up to $60 billion in Treasuries mature each month without replacing them, reducing the amount of money circulating in the economy. The idea is that QT can help exert some downward pressure on prices.

But there’s also some downside to the practice — changing the amount of liquidity in the economy and redirecting that money could have some major consequences.
