The heavy is the root of the light; stillness is the master of haste. And so the sage travels all day without leaving the supply wagons behind.

—— Laozi, Tao Te Ching, ch. 26 (Spring and Autumn period; my own translation)

On the October 12, 2026 episode of Macro Musings, David Beckworth hosted John Rolle, governor of the Central Bank of The Bahamas, to talk about one thing: what a central bank actually does all day when its currency is nailed to the US dollar. Rolle said the Bahamian dollar has been pegged one-to-one since the 1960s, that the law requires reserves covering only 50% of the bank’s demand liabilities, and that recent coverage has often run above 100%, with the domestic banking system carrying a risk-weighted capital ratio above 30%. His conclusion: in an economy like this, monetary policy collapses into defending the currency — and the setup only works while the buffers stay thick and the fiscal side cooperates. Loosen either condition and the adjustment arrives as austerity, because the exchange rate will not do any of the work for you.

The case at its strongest

Rolle starts with geography. Most of the visitors come from the United States — he says at least four-fifths of the business is US-sourced — tourism is priced in dollars, and the two economies’ cycles move together. He uses the textbook phrase “optimum currency area” to describe his own situation: the misalignment pressures that normally punish a fixed exchange rate hit The Bahamas more lightly, because its cycle was already following its neighbour. Peg to the dollar and you import low, stable US inflation along with it.

Then comes the line I thought was the best in the episode. Under inflation targeting, Rolle says, policy failure shows up as inflation. In The Bahamas, policy failure shows up as a loss of foreign reserves. Same job, different gauge — so he doesn’t watch CPI, he watches the channels foreign exchange comes in through (tourism and financial services earnings) against the channels it leaves through (ordinary income spending, plus whatever credit expansion conjures up). The balance between those two decides whether he intervenes.

He is blunt about the hardest part. Policy in a small open economy has to be procyclical: when tourism earnings weaken and the foreign exchange supply thins out, the textbook Keynesian response is stimulus — but stimulus hits the demand side, and the demand side calls for more foreign exchange. So when an external shock lands, a central bank like his has to lean on demand and make the downturn hurt more. Buffers exist to buy back some room: with enough reserves you can tolerate demand running ahead of earnings for a while and wait for the tourists to come back on their own.

On fiscal policy he avoids the word “independence” and talks about interdependence. The central bank doesn’t set the deficit target, but it has a say in how the government finances the gap, and it says it plainly: some imbalances are only sustainable if the financing is in foreign currency. That was the pandemic lesson — fiscal support, fine, but the money had to come from outside. What the government did then was stabilisation, he says, with expenditure held roughly flat plus basic social support, and even that produced deficits large enough that the path back below 70% of GDP, and down into the 60s, runs more than half a decade. The pre-pandemic medium-term goal had been under 50%.

Then the banks and the Sand Dollar. He doesn’t present that 30%-plus capital ratio as an achievement — he calls it capital the banks are sitting on that ought to be put to work, and says he’d like to bring it down gradually over the medium term. The Bahamas doesn’t use countercyclical buffers; it prefers to keep one thick buffer permanently and siphon it off slowly now, while nobody is exuberant, so that the return of exuberance doesn’t produce a credit explosion. The Sand Dollar reads as infrastructure: an archipelago, sparsely populated, physical delivery of financial services too costly to solve with branches, so the channel went digital. The central bank keeps the ledger but provides no retail service — wallets come from financial institutions, people can transfer directly to each other, the central bank cannot see who paid whom, and the AML visibility sits with the payment providers. It’s already wired into the automated clearing house and moves money faster than the banking system. And then hurricanes, where he raised something I hadn’t considered: the resilience The Bahamas needs includes paying people while offline, and that needs one unifying instrument that looks a lot like digital fiat.

Now the other side: who pays for this

The first objection is the plainest one. Importing someone else’s monetary policy means the tool is in someone else’s hands. The Fed moves, you move, whatever your own conditions look like. Rolle concedes the policy has to be procyclical, which in plain language means his central bank is obliged to deepen the pain exactly when the country needs help least. Buffers make that arrive later and softer; they don’t make it go away. Real activity contracted 20–25% in 2020 and the recovery wasn’t complete until late 2022 into early 2023. The peg didn’t block that hit, it routed the entire adjustment into fiscal policy and domestic demand.

The second is capital controls. Beckworth assumed The Bahamas had picked the fixed rate plus free capital flows, and Rolle corrected him on air: the controls exist, with the emphasis on short-term flows, and more room given to long-term investment inflows. That is the leg of the trilemma actually being surrendered. A resident who wants foreign assets goes through a designated portfolio channel. It never appears as a line item, and it is a tax locals pay for decades.

The third is that 30% capital ratio, which Rolle himself calls idle — and underneath it sits a more structural problem. A small financial system can’t reach economies of scale, so the boundary of what counts as a public good keeps shifting toward the central bank. He’s candid about this: when other countries build instant payment systems, central banks often have to lead the investment, because the private sector sees no return appeal up front. Which licenses a less flattering reading of the Sand Dollar story: the central bank built it because nobody else would.

Which leads to the fourth objection, the one I find hardest to answer. The world’s first nationwide CBDC is six years old and the merchant ecosystem still isn’t there. Rolle says it himself — without that ecosystem, you don’t see the full range of adoption cases, peer-to-peer, person-to-business or person-to-government. It’s faster than the banks, and whether the shop takes it is a separate question. Meanwhile the substitute is growing: dollar stablecoins already circulate at scale across emerging markets, and his answer is that it isn’t imminent, that the capital control regime doesn’t bar residents from holding them, and that they come in through the portfolio channel. The real stress test is the day a tourist pays with a stablecoin — and he flags the current irony himself: cheap on the rails, expensive and slow at the on- and off-ramps, so the savings get clawed back at the doors.

The fifth objection targets what the episode treats as an asset: national consensus. Rolle describes a strong national consensus around currency stability, with austerity accepted when it’s needed, so that political debate becomes a contest over who supports the objective better. He points to Barbados as a comparison — and Barbados spent part of the last decade under severe austerity. Willingness to swallow austerity is political capital, it depletes, and it isn’t an institutional guarantee. Add hurricanes and sea level rise, where he says the methodology for putting climate risk into stress tests is still being refined, which means how much credit exposure sits on ground that floods is still being counted.

My read: which condition decides it

I came away thinking the bullish case holds, but it stands on one narrow condition: buffer thickness. Coverage above 100% and capital above 30% are both the reason this works and the premium it pays every year. Buffers are a stock, and consecutive shocks eat stocks — the fiscal space the pandemic consumed takes The Bahamas more than half a decade to rebuild. So if I were watching this country, I’d watch two numbers: whether reserve coverage drifts back toward the statutory 50%, and whether the government’s foreign-currency financing gets more expensive. Either one, and the adjustment mechanism switches from “buffer absorbs it” to “austerity completes it” — with the exchange rate still refusing to move.

Three things here travel beyond The Bahamas.

The first is the instinct that a company sitting on a pile of cash is wasting it. My own first reaction to large cash balances and conservative allocation used to be poor capital efficiency. The Bahamas suggests the opposite reading: when your downside is exogenous and printing money isn’t on the menu, the buffer is the only policy tool you have left. So before calling an idle resource wasteful, ask who decides your bad weather. If the decision sits with you, idle is idle. If it sits outside, that money is buying down the odds of being forced to act at the worst possible moment.

The second is the question of why bad news always seems to force selling at the bottom. That’s procyclicality, and the personal version matches the central bank’s exactly: income weakens while fixed demands don’t, so something has to be sold to cover. Rolle’s answer is to accumulate something spendable during good weather; the personal equivalent is the ratio between cash on hand and fixed monthly costs. I’ve never done this well — the one time I needed money last year happened to be the moment my positions looked worst, and the lesson wasn’t that I’d read the direction wrong, it was that I had no buffer.

The third is how much “first to build it” is worth. The Sand Dollar got the technology finished, which converted the problem into an adoption problem, and the adoption problem jammed at the merchant end for six years. Next time I meet a “we were first” narrative, I’ll go looking for whether anyone has picked up the last link in the chain — the first to build something is often also the first to discover that the remaining distance is the hard part.

I saved the most counterintuitive piece for last. Rolle says part of the work ahead includes improving access to physical cash, and that doing so would help digital adoption — he calls it a cash safety net: people need to believe they can walk out before they’ll walk in. What that made me think of wasn’t payments at all, it was every situation where you’re asking someone to change a habit. Leave the old road open, and keep it in decent repair, if you want anyone to try the new one.

The One Thing to Take Away

One idea: in a game whose rules you can’t change, the buffer is the only policy tool you still control. The Bahamas can’t print, can’t let the exchange rate absorb a shock, and can’t decide whether American consumers feel like travelling this year. The one thing it can decide is how much it has piled up before the weather turns — which is why it would rather carry a capital ratio people call idle than be forced into something more painful during the month tourism stops.

Here’s something I’ve tried, offered rather than prescribed: pick one thing you’re afraid might break — a job, your health, a relationship — and write down what you’d need in the first month after it broke. Not a vague “money,” but specifics: three months of rent, one person’s phone number, a check-up you’ve been postponing. Then take the cheapest item on that list and get it ready this week.
