QE Without the Mythology

On 3 November 2010 the Federal Reserve announced it would buy $600 billion of US Treasuries, and the next morning Ben Bernanke explained himself in the Washington Post. The internet settled on a shorter summary: money printer go brrr. The meme is wrong in an interesting way. Nothing was printed. No new pound or dollar landed in anyone's account. The central bank swapped one government liability for another, and the reserves it created cannot buy so much as a meal deal at Tesco. Hold that thought. Because once you understand what QE actually did, from the mouths of the people who ran it, the honest version turns out to be worse than the meme.

Mechanically, QE is an asset swap. The central bank creates new reserves (deposits that commercial banks hold at the central bank and nowhere else) and uses them to buy government bonds. When the Bank of England buys a gilt from a pension fund, the fund's bank receives reserves and credits the fund with a deposit. The private sector held a gilt; now it holds a bank deposit, and the bank holds a claim on the Bank of England. Reserves are interbank money. They settle payments between banks; they cannot be withdrawn, spent in shops, or "lent out" to the public. A bank stuffed with reserves does not lend more because of them; lending creates deposits, as the Bank of England's own researchers have patiently explained. So no, the printer did not go brrr.

But Bernanke never claimed it did. He claimed QE works through portfolio rebalancing: remove safe assets from the market and their former holders go hunting for yield in riskier ones. His 2010 op-ed spelled out the intended results: cheaper mortgages, cheaper corporate borrowing, and, in his own words, higher stock prices boosting consumer wealth and confidence. Read that again. Asset-price inflation was not an unfortunate side effect of QE but the transmission mechanism, described by the operator, in a national newspaper, at launch. The policy worked precisely to the extent that it made the owners of financial assets richer and hoped some of it would trickle into spending. That is the honest, no-strawman version.

Now follow who gains. Governments borrowed at suppressed yields for a decade because the largest and least price-sensitive buyer in the market stood permanently behind it. The Bank of England eventually held £875 billion of gilts, and in several years absorbed roughly what the Treasury issued. Cheap deficits are a policy gift no chancellor refuses. Meanwhile the Bank's own 2012 distributional analysis conceded that QE's wealth gains flowed overwhelmingly to the households that already owned assets. The top 5% held some 40% of them. This is the Cantillon effect from Module 4 wearing a lanyard: new money enters at a specific point, and proximity to that point is the payoff. Savers and wage-earners stood at the end of the queue, again.

Finally, the tell: the asymmetry. Balance sheets expand in weeks and contract, when they contract at all, over years: passively, apologetically, and paused at the first tremor. The Fed's 2017–19 runoff ended in the September 2019 repo seizure; the Bank of England's first-ever gilt sales were days from starting when the 2022 LDI crisis forced it to buy instead. Quantitative tightening is QE's undo button, and it has never been fully pressed. A tool that ratchets one way is not a cycle-management instrument; it is a standing subsidy to asset owners and borrowers with occasional intermissions. Know the machine before you condemn it. Described accurately, it condemns itself.
