The Cash Kingdom
Walk through Coronation Market in downtown Kingston on a Saturday morning and you'll see Jamaica's real economy in motion. Higglers (informal market traders) move farm produce, manufactured goods, and household items by the truckload. Millions of dollars change hands monthly. No bank accounts, no card terminals, no invoices. Just cash, handshakes, and trust.
This isn't a fringe activity. According to World Economics, Jamaica's informal economy accounts for approximately 30.7% of GDP (roughly US$13 billion in economic activity that happens entirely outside the formal financial system. The Inter-American Development Bank has estimated that informal activities represented as much as 43% of official GDP in earlier measurements, and by some accounts the sector has only grown.
The Jamaica Observer reported in early 2026 that economists typically estimate informal production in small developing economies accounts for 20 to 40 per cent of gross domestic product. Jamaica sits firmly in that range.
Higglers are the backbone of this system. A study by the Hungry Cities research group found that domestically produced foods flow into Kingston largely through Jamaica's higgler system, with these informal vendors performing functions as market intermediaries) trade, harvesting, post-harvest processing, re-distribution, and sales. They are not just sellers. They are logistics, warehousing, and distribution, all without a single bank loan.
The Partner: Jamaica's Original Peer-to-Peer Network
Long before Bitcoin existed, Jamaicans had the Partner system.
A Partner (also known as susu, sou-sou, or pawdna across the Caribbean) is a rotating savings and credit association. A group of people pool money regularly, and each member takes the full pot in rotation. If ten people contribute J$10,000 each week, one person receives J$100,000 that week. The cycle continues until everyone has had a turn.
It's peer-to-peer finance with no middleman, no interest, no bank, and no smart contract. Just trust, reputation, and a shared understanding of how the system works.
The GDRC's documentation of Jamaica's Partner system notes that respondents used banks for "emergencies" and the partner for predictable major expenses such as school fees. One bank saver admitted: "It's pure withdrawals." The partner was where actual savings happened.
A study published in the Journal of Development Economics found that involvement in partners reflects "a traditional response to the alienation of sections of the population from the formal financial sector." The same study noted that partners became so popular in Jamaica that a commercial bank introduced a "Partner Plan" savings account mimicking the arrangement.
The Partner system isn't a workaround for people who don't understand banking. It's a parallel financial infrastructure built by people who were never invited into the formal one.
Why 23% of Jamaicans Don't Have a Bank Account
The Bank of Jamaica's 2023 National Financial Inclusion Study found that 22.8% of Jamaican adults are unbanked (they have no account at any formal financial institution. A further 6.3% are underbanked.
The numbers get starker when broken down by income. The BOJ study found that 32% of lower-income respondents were unbanked, compared to just 4.4% of upper-income respondents. Among working-class Jamaicans, only 79.8% were banked. Among lower-income groups, the figure was 59.6%.
This isn't accidental. The English Caribbean's banking system was built during colonial rule, and its lending policies were, as business historian Monteith documented, "highly selective and restrictive." A 2018 study published in E-International Relations found that colonial banking practices in the region were explicitly racialized) banks fostered a certain type of clientele and engaged in "discriminatory practice."
Then came the 1990s. Jamaica's financial sector collapse was catastrophic. According to the Jamaica Observer, the damage reached approximately J$140 billion by the time the Financial Sector Adjustment Company (FINSAC) wrapped up. Of 37 banks, 21 were classified as failed, with 14 going down in 1998 alone. The Jamaica Gleaner reported that some commercial banks were not adequately capitalised and regulatory forbearance weakened them further.
The government absorbed the losses. The public paid. And trust in formal finance took a generational hit.
Is it any wonder that nearly a quarter of Jamaican adults still choose cash under the mattress and a Partner over a bank account?
The Problem With Cash
Cash works locally. It breaks at the border.
A higgler at Coronation Market can sell J$50,000 worth of produce in a morning and handle every transaction with cash. No fees, no downtime, no device needed. But the moment that same higgler needs to pay a supplier in Miami, send money to a child studying abroad, or receive payment from a customer in London, the informal system hits a wall.
That's where Western Union, MoneyGram, and the banks step in (and where the fees start eating. As covered in our previous article, Jamaica loses an estimated US$213 million per year to remittance fees, with average costs of 6–9% per transaction. Bank wires cost $35 or more per transfer.
Cash is also physically vulnerable. Theft, fire, flooding, and hurricanes) which Jamaica knows all too well (can destroy a lifetime of savings in minutes. There's no backup, no recovery, no insurance.
The informal economy works. But it has a ceiling, and that ceiling is set by the cost and friction of crossing borders.
Lightning Keeps the Informality
Here's the critical point: the Lightning Network doesn't try to replace Jamaica's informal economy. It does something more subtle) it removes the ceiling while keeping everything that works.
Lightning is a peer-to-peer protocol built on top of Bitcoin. As of March 2026, it has over 17,000 public nodes and approximately 40,000 public payment channels, with a total network capacity of around 4,900 BTC. It is not a separate blockchain. It has no own token, no validators, no board of directors. It inherits Bitcoin's security model and adds instant, near-free payments.
A typical Lightning payment costs 1–50 satoshis (fractions of a cent) regardless of the amount being sent or the on-chain mempool congestion. Compare that to a bank wire ($35), a Western Union transfer (6–9% of the amount), or even an on-chain Bitcoin transaction (potentially thousands of satoshis during peak demand).
Lightning is, in many ways, digital cash. No bank required. No KYC for small amounts. No minimum balance. No monthly fees. No branch visit. No credit check. You hold your own keys, you transact directly with whoever you want, and the network routes the payment through intermediary nodes (none of whom know the full path of the payment, thanks to onion routing.
Sound familiar? It should.
A Lightning payment channel is essentially a Partner agreement between two parties. They lock up funds together, transact back and forth off-chain, and settle on Bitcoin when they're done. The routing nodes that move payments between parties who don't have a direct channel? That's the higgler network) intermediaries who move value between points of demand, taking a small fee for the service.
The cultural parallel isn't forced. Jamaica already runs on peer-to-peer trust networks. Lightning just gives those networks a protocol that works across borders.
The 23% Don't Need a Bank. They Need a Wallet.
The BOJ's financial inclusion study revealed something important: the unbanked aren't people who tried and failed to get bank accounts. They're people who looked at the cost, the paperwork, the minimum balances, the branch locations, and the history, and made a rational decision to stay in cash.
Lightning wallets don't ask for any of that. You download an app, generate a key pair, and you're in. No ID, no minimum deposit, no monthly maintenance fee, no overdraft charges. You can receive money from anyone, anywhere, in seconds, for less than a cent.
For the higgler, this means accepting payment from a customer in Toronto without Western Union taking a cut. For the Partner, it means settling the pot in seconds instead of waiting for the weekly meeting. For the taxi driver, it means taking payment from a tourist without making change. For the family receiving remittances, it means keeping 98% of the money instead of 91%.
This isn't theoretical. It's already starting.
Already Happening
Flash, a Bitcoin and Lightning wallet built in the Caribbean, is one example. According to Forbes, it's being used by Jamaican businesses to send funds from US entities to Jamaican operations, saving $35 per month in bank wire fees. Transfers between Flash users are free. Cashing out to a local Jamaican bank costs 2% (compared to the 6–9% charged by traditional remittance services.
During hurricane relief efforts in late 2025, Flash was used to run fundraising campaigns through a BTCPay Server plugin, demonstrating that the infrastructure works even in disaster scenarios when traditional banking is disrupted.
Flash isn't the only option. Wallet of Satoshi, Blink, Breez, and dozens of other Lightning wallets offer similar functionality. The point isn't any one app) it's that the protocol is open, and anyone can build on it. Just like anyone can start a Partner.
The Culture Was Always Ready
Jamaica's relationship with money has always been defiantly self-reliant. From the Maroons who built independent communities outside colonial control, to the higglers who built a parallel trade network, to the Partner system that gave people access to capital without a bank (the island has always practiced financial sovereignty without calling it that.
Bitcoin didn't introduce peer-to-peer money to Jamaica. It just gave the existing peer-to-peer economy a way to go global.
The informal economy isn't a problem to be solved. It's a network to be upgraded. Lightning keeps the trust, keeps the speed, keeps the no-middleman ethos) and removes the ceiling.
The money was always moving. The question was always who takes a cut. Lightning makes the answer: nobody.
