"The Fed is printing money" is a common shorthand for quantitative easing — but it's not literally accurate. The Fed doesn't print physical cash for QE; it creates new bank reserves electronically and uses them to buy large quantities of government bonds (and sometimes other securities) from banks and other institutions, expanding its own balance sheet in the process.
QE is typically used when the economy needs support but short-term interest rates are already near zero, leaving the Fed's normal tool (cutting rates) with little room left to work. By buying huge quantities of bonds, the Fed pushes bond prices up and yields down — making already-safe assets pay even less.
Insider Angle: here's the mechanism that actually inflates asset prices: when safe bonds pay almost nothing, investors seeking any meaningful return get pushed further out the risk spectrum — into corporate bonds, then stocks, then even riskier assets — bidding those prices up in the process. This is sometimes called the "portfolio rebalancing channel," and it's a big part of why QE eras have often coincided with strong stock market performance. It's also the core of the biggest criticism: QE's benefits flow disproportionately to whoever already owns stocks and real estate (who see those assets appreciate), while its connection to broader wage growth and Main Street economic benefit is much less direct and more debated.
