Latest / Monetary Policy Explained with Fexingo: Central Banks, Money Supply, and Interest Rates / How Central Banks Use Helicopter Money Without Dropping It
Transcript
- Lucas: So helicopter money — the idea that a central bank just prints money and hands it directly to people, no debt attached — it's one of those concepts that comes up in every crisis, gets dismissed as fringe, and then quietly gets studied by serious economists. But it actually happened in a real economy, at scale, and nobody calls it helicopter money. Luna: Wait — which country? Because I'm thinking of the US stimulus checks in 2020, but those were funded by Treasury borrowing, not the Fed printing. Lucas: Exactly the distinction. The US checks were fiscal policy — Congress authorised spending, Treasury borrowed, Fed happened to monetise some of it. That's not helicopter money. True helicopter money means the central bank creates reserves out of thin air and transfers them to households, with no offsetting liability and no expectation of repayment. Brazil in 2020 did something close. Luna: Right — Brazil's Auxílio Emergencial, the emergency cash transfer. I remember reading that it covered something like a third of the population. Lucas: Yes, about 65 million people received 600 reais a month initially, later 250 reais. That's roughly 30 percent of the population. And here's the twist — the program was formally run by the government, but the Central Bank of Brazil essentially financed it by buying government bonds that were issued specifically to fund the transfers. In a narrow sense, the central bank's balance sheet expanded, the government didn't raise taxes or cut spending, and households got cash. That's the mechanical core of helicopter money. Luna: But the government still issued debt. Doesn't that make it fiscal policy with monetary accommodation, not pure helicopter money? Lucas: It does — and that's why most economists say true helicopter money has never been tried. The pure form requires the central bank to bypass the Treasury entirely. But in practice, the line blurs. Brazil's program shows you can get the same economic effect: household balance sheets improve, demand recovers, and the central bank's money creation doesn't get reversed later. Luna: So why is this tool so taboo if it's just a more direct version of what QE already does? Lucas: Because QE buys assets — bonds, mortgage securities — and those assets sit on the central bank's books. Helicopter money goes straight to people who spend it. That's far more stimulative per dollar and far harder to reverse. If you create money and it circulates through the real economy, inflation expectations can detach quickly. Central bankers hate losing control of expectations. Luna: And there's a credibility issue too, right? Once you start giving money away, people might expect it to become permanent. Lucas: Exactly. That's the 'temporary versus permanent' problem that Milton Friedman himself flagged in his 1969 essay where he coined the term. He imagined a helicopter dropping money from the sky — a one-off event. But in a democracy, once a transfer program exists, it's politically nearly impossible to take away. Brazil's program was supposed to last three months; it lasted over a year, and parts of it were extended again in 2021. Luna: So the fear is that a central bank would lose its independence, effectively becoming a tool for fiscal policy on autopilot. Lucas: Yes. That's what some economists call 'fiscal dominance' — when the central bank has to accommodate government spending regardless of inflation risks. Helicopter money is fiscal dominance by design. And yet, the academic arguments for it have become more mainstream since the pandemic. Luna: Who's making the case now? Lucas: John Cochrane at Stanford has written about it as a thought experiment in the context of the zero lower bound. Adair Turner, former UK financial regulator, argued in a 2015 book that helicopter money might be the only tool left when rates are at zero and QE has diminishing returns. And more recently, some economists at the IMF have modelled scenarios where direct household transfers from the central bank outperform QE at boosting demand, with only modest inflation overshoot. Luna: But does the IMF actually endorse it? That would be a big shift. Lucas: Not an endorsement — more like 'we should understand the mechanics because someday we might need it.' The 2020 Brazil experience gave them real data. Researchers at the Central Bank of Brazil published a paper showing that the Auxílio Emergencial transfers had a fiscal multiplier around 1.2, meaning each real of transfers generated 1.20 reais in GDP. That's higher than typical tax cuts. Luna: And inflation? Brazil had high inflation through 2021 and 2022, partly driven by those transfers, right? Lucas: Partly. But Brazil's inflation had multiple causes — supply chains, exchange rate depreciation, commodity prices. The transfers definitely added demand pressure, but the Central Bank raised its policy rate from 2 percent to 13.75 percent over that period and eventually brought inflation down. So the system worked — the helicopter drop didn't spiral out of control, but it did require aggressive rate hikes to offset. Luna: So the lesson might be that helicopter money is usable, but only if you're willing to slam the brakes later — which is politically painful. Lucas: Exactly. And that brings us to the digital angle. With central bank digital currencies — CBDCs — the technical friction of distributing money directly to every citizen drops to near zero. A central bank could credit every digital wallet instantly in a crisis. That's why the debate has shifted from 'should we' to 'under what conditions should we.' Luna: And that's also why the ECB and the Bank of Japan have quietly funded research into helicopter money mechanisms, even while publicly rejecting it as a policy option. Lucas: Right. Christine Lagarde said in 2022 that helicopter money is 'a very interesting concept, but not on the table.' That's central banker for 'we're studying it intensely.' Luna: So where do you stand — do you think we'll see a genuine helicopter drop in the next decade? Lucas: I think we'll see a hybrid — something like 'digital stimulus tokens' that expire after a set period, designed to be spent quickly and then withdrawn from circulation. That avoids the permanence problem. A few academic papers have proposed exactly that: central bank issued digital money that self-destructs after 90 days. Luna: Fascinating. And terrifying for anyone who values central bank independence. Lucas: Yeah, it's a trade-off. But look — if we're going to have a deep recession and rates are at zero, the options are unpleasant. Helicopter money might be less unpleasant than depression. Luna: On that note — before we wrap, a quick honest thing. If walking through the economy with us has made something click, a handful of listeners chip in monthly through buy me a coffee dot com slash fexingo. That's literally what funds making this many of these. Lucas: Yeah, it's a small group, but it keeps the show ad-free and independent. No pressure, just if you find value in the deep dives. Luna: Exactly. And for everyone else, we're grateful you're here. Back to the mechanics. Lucas: So the key takeaway — helicopter money is not a fringe fantasy. It has a real-world analogue in Brazil, a growing academic literature, and a plausible digital future. But the institutional guardrails that prevent it from becoming permanent are still being designed. And that's the real conversation central bankers are having behind closed doors. Luna: What's the next frontier? cbdc based helicopter drops with expiration dates? Lucas: Exactly. Or even 'smart money' that can only be spent on certain goods — a kind of digital scrip. That would give central banks targeting power they've never had. Whether that's a good thing or a dangerous overreach depends on how you weigh effectiveness against freedom. Luna: Alright, that's a good cliffhanger for the next episode. Thanks Lucas. Lucas: Thanks Luna. And to our listeners — keep thinking critically about the tools behind the headlines.
