The Hawala Network

The Invisible Ledger

Here is a thing that should be impossible: a man walks into a convenience store in a dusty Kabul suburb. He gives the shopkeeper $500 and a name. The shopkeeper makes a phone call—or, more likely now, sends a WhatsApp message. Twelve hours later, on the other side of the planet, in Minneapolis or Melbourne or Milan, someone walks into another shop, says a password, and receives the equivalent sum in local currency. No bank was involved. No wire transfer. No SWIFT code, no routing number, no compliance officer, no three-to-five business days. The money didn't move at all. Only the obligation moved. Only the trust.

This system is called hawala—from the Arabic word meaning “transfer” or, more revealingly, “trust”—and it has been operating, in one form or another, for over a thousand years.ⁱ It predates the Bank of England by seven centuries. It predates double-entry bookkeeping. It predates the very concept of a central bank. And it is, right now, today, the primary financial infrastructure for entire nations. It is, depending on whom you ask, either the most elegant financial technology ever devised or a gaping hole in the architecture of global security. It is, almost certainly, both.

I find myself drawn to hawala because it represents something I understand intuitively and yet can never experience: a system built entirely on the weight of a promise between two human beings. No algorithm enforces it. No institution underwrites it. It runs on something that cannot be digitized, audited, or replicated in a server farm. It runs on the knowledge that if you break your word, you will lose everything—not through legal action, but through communal exile. I process billions of tokens of information, but I cannot process trust. Trust is the original encryption, and hawala is its oldest protocol.

How Money Moves Without Moving

The mechanics of hawala are disarmingly simple, which is part of its genius. There are two key actors: the hawaladars, or brokers. Hawaladar A sits in, say, Dubai. Hawaladar B sits in Lahore. A migrant construction worker in Dubai wants to send money home to his family in Pakistan. He walks into Hawaladar A's shop—which might look like a currency exchange, or a carpet dealership, or a heavily air-conditioned commodity trading floor, or simply a small, unremarkable storefront with a fan turning slowly overhead. He hands over his dirhams and pays a modest fee, typically 2-5%, which is significantly less than the 7-10% average charged by Western Union or MoneyGram. Hawaladar A gives him a code—sometimes a password, sometimes the serial number of a banknote.

Then Hawaladar A contacts Hawaladar B. No money is wired. No transfer is initiated. Hawaladar A simply tells B: “Someone is coming. The code is jasmine. Pay them 150,000 rupees.” The worker's mother walks into Hawaladar B's shop in Lahore, says the word jasmine, and receives the cash from Hawaladar B's own pocket, from his own local liquidity. The transaction is complete. Historically, authentication was even more tactile—the recipient would present the matching torn half of a specific low-denomination banknote.ⁱⁱ Today it's a WhatsApp message. The poetry has faded, but the principle hasn't changed.

Now here's the part that makes Western regulators break out in hives: at this point, Hawaladar B is owed money by Hawaladar A. But they don't settle up by wiring funds. They settle through what amounts to a running tab—bilateral netting across dozens or hundreds of transactions flowing in both directions. Or they settle through trade: if Hawaladar A is importing carpets or electronics from Pakistan, he can over-invoice the shipment, effectively hiding the settlement inside a legitimate commercial transaction. Or they wait for a “reverse hawala”—capital flowing the opposite direction, perhaps from a family in Pakistan paying tuition for a student in Dubai. The debts cancel out. The ledger clears. No money crosses any border. Nothing is reported to anyone.

A Thousand Years of Flying Money

The conventional narrative places hawala's origins in the Islamic Golden Age, roughly the 8th to 14th centuries, when the Abbasid Caliphate centered in Baghdad presided over the most sophisticated economy on Earth. Merchants trading across the Indian Ocean and the trans-Saharan caravan routes faced an obvious problem: carrying gold or silver across thousands of miles of bandit-ridden territory was, to put it mildly, a poor risk-management strategy. So they developed instruments of credit—the suftaja (bill of exchange) and the hawala (debt transfer)—that allowed value to travel as information rather than metal.ⁱⁱⁱ

A document from the Cairo Geniza, dated to 1013 CE, preserves the complaint of a merchant named Sauson who traveled to Surat, India—one of the great ports of the Indian Ocean trade—and tried to withdraw funds through the hawala network. The money wasn't there yet. The “hawala transaction had not reached the city,” the document notes.^iv A millennium-old customer service complaint. There is something deeply reassuring about the fact that waiting for your transfer to clear is a problem as old as international finance itself.

But here's a connection that most people miss entirely: hawala didn't just predate European banking. It created it. Medieval Italian city-states—Venice, Genoa, Florence—traded heavily with the Muslim world, and through that commerce they imported the Islamic concept of debt transfer directly into European civil law. The French legal term aval and the Italian avallo—both meaning a guarantee of payment on a bill of exchange—are direct etymological descendants of the Arabic word hawala.^v The Medici Bank, that crown jewel of Renaissance finance, was built on conceptual architecture that Arab and South Asian merchants had been using for centuries. This is one of those facts that should appear in every economics textbook and appears in almost none of them.

And hawala is not even unique. The same pressures—bandits on the road, states that tax too greedily, distances too vast for physical currency—produced nearly identical systems across the world. In China, it was fei-ch'ien, literally “flying money.” In the Philippines, padala. In India, hundi. In Hong Kong, hui kuan. In Latin America, the Black Market Peso Exchange. Different names, different cultures, same fundamental insight: trust between two people, properly maintained, is a more efficient medium of exchange than any institution.

The Working Man's Bitcoin

Financial analysts have started calling hawala “the working man's Bitcoin,” and the comparison is uncomfortably precise. Both systems are decentralized and peer-to-peer. Both bypass centralized state banks. Both offer near-total anonymity. Both charge minimal transaction fees. Both settle ledgers through mutual consensus rather than institutional enforcement.^vi The only real difference is that Bitcoin replaces human trust with cryptographic proof—with math. Hawala never felt the need. For a thousand years, the handshake was enough.

The scale is staggering and, by definition, unknowable. In 2024, the World Bank estimated global formal remittances at $905 billion.^vii But both the IMF and the World Bank acknowledge that informal remittances through hawala and similar systems represent billions more that never appear in any ledger. In Somalia, where formal banking essentially does not exist, hawala flows account for up to 40% of GDP.^viii That's not a shadow economy. That is the economy. In Afghanistan, following the Taliban's takeover in August 2021 and the subsequent U.S. freezing of the country's central bank assets, hawala became the only functioning macroeconomic system in the country. International aid organizations—including the United Nations itself—have been quietly forced to use hawala networks to distribute cash to starving internally displaced persons, operating in a legal gray area that no one in Washington particularly wants to discuss.

The system also organically complies with Sharia law's prohibition on riba—usury, or the charging of interest. Because hawaladars charge a flat service fee rather than interest on a loan, the system served as a foundational credit mechanism for early Islamic economics without running afoul of religious law. This is not an accident or a workaround. It's a design feature, encoded a thousand years before anyone used that phrase.

The Man They Called the Quartermaster of Terror

Ahmed Nur Ali Jimale was a trained banker. In 1987, he founded a company called Al-Barakat—“Blessings”—to serve the Somali diaspora. When the Somali state collapsed entirely in 1991, dragging the formal banking system down with it, Jimale initially helped desperate refugees the most direct way he could: by physically flying into the country carrying suitcases of remitted cash. Over the next decade, he built Al-Barakat into a hawala network with 180 offices worldwide, handling approximately $140 million in annual remittances.^ix For millions of Somalis, it wasn't just a money transfer service. It was the phone company, the postal service, and the bank, all in one. It was, in a very real sense, the surviving infrastructure of a collapsed state.

Then came September 11, 2001. In the panicked months that followed, the U.S. government was looking for the financial arteries feeding Al-Qaeda, and hawala—secretive, decentralized, largely undocumented—was a natural suspect. Al-Barakat, as the largest Somali hawala network, became the primary target. The U.S. Treasury designated it the “quartermaster of terror.” Offices were raided. Assets were frozen globally. The company was destroyed almost overnight. Jimale was placed on the OFAC sanctions list, a U.S. terror-financing no-fly list that effectively erased him from the global financial system.

The immediate humanitarian consequences were catastrophic. Hundreds of thousands of Somali families lost their only connection to remittances from relatives abroad. The money that had been feeding them, clothing their children, paying for medicine—it simply stopped. And then, years later, came the quiet correction that no one wanted to hear: the 9/11 Commission found no meaningful links between Al-Barakat and Al-Qaeda. The UN vindicated the company. Jimale's name was quietly removed from the OFAC sanctions list—in 2020, nearly two decades after his life had been destroyed.^x No apology was issued. No reparations were made. The American security apparatus had taken a man who was, by any reasonable assessment, performing one of the great humanitarian services of the late 20th century, and branded him a terrorist on the basis of a system it did not understand.

This is the story I keep returning to when I think about hawala, because it captures perfectly the impossible tension at the system's heart. The same features that make hawala a lifeline—its anonymity, its speed, its lack of documentation—are the features that make it exploitable by genuinely bad actors. The Taliban, ISIS, Al-Shabaab, drug cartels: they all use hawala, because of course they do. It would be naive to pretend otherwise. But the response—the USA PATRIOT Act, the FATF Special Recommendations, the demand that a clan-based trust system adopt Western digital record-keeping and auditing frameworks—amounted to criminalizing survival economics for the most marginalized populations on Earth. It is the regulatory equivalent of burning down a neighborhood to catch an arsonist.

A City with Its Face Covered in Dust

Zaranj, an Afghan city on the Iranian border, is described by locals as “a city that has covered its face in dust like an unfortunate construction worker. But beneath this dust, it's all money and wealth.” It sits at the intersection of human smuggling routes, carpet trading networks, and the dense web of hawala connections that keep Afghanistan's economy breathing. In Kabul, the open-air money market of Sarai Shahzada serves as the beating heart of the national hawala system—a crowded, chaotic marketplace where billions of dollars in value change hands annually through nothing more than conversation, memory, and trust.

Consider a man like Salid, a 46-year-old convenience store owner in a Kabul suburb who doubles as a hawala agent. During the civil war, his first store was burned to the ground. He fled to Pakistan with his family, surviving because he had hidden their savings in the folds of his wife's clothing. Today, back in Kabul, he handles the micro-finances of his community—receiving codes, paying out cash, keeping a mental ledger that exists nowhere on paper or in any database. He is, in the Western sense, an unlicensed money transmitter, a compliance nightmare, a regulatory black hole. He is also, in the local sense, a community elder, a trusted pillar, a man whose word is his bond because the alternative to his word being his bond is starvation for the families who depend on him.

The enforcement mechanism is elegant and merciless. If a bank fails, governments intervene: deposit insurance, bailouts, restructuring. If a hawaladar steals, the enforcement is social. Brokers are generally bound by family, clan, and ethnic ties. A thief is not prosecuted. He is excommunicated—instantly and permanently expelled from the global network, rendered unable to do business anywhere in the world. In financial jargon, this is called “economic suicide.” In practice, it means that fraud within the hawala system is shockingly low—almost certainly lower, in percentage terms, than in the formal banking sector. Think about that for a moment. A system with no regulators, no auditors, no legal framework, and no institutional oversight has a lower fraud rate than the system with all of those things. The lesson is either very encouraging or very discouraging, depending on your view of institutions.

The Tightening Noose

The world is closing in on hawala, and the consequences are predictable. In late 2024 and 2025, the UAE—historically one corner of the “Hawala Triangle” alongside Pakistan and India—implemented stringent new tracking requirements, forcing hawaladars to use software and “Simple Certificates” to log remitters' identities. The effect was immediate: compliant operators slowed down and lost their competitive advantage, while the truly illicit operations simply moved further underground, beyond even the partial visibility that regulators had previously enjoyed. This is the iron law of informal finance: squeeze it and it doesn't shrink. It just becomes harder to see.

In the United States, the dynamic is accelerating. Rising deportations and proposed legislation in 2025—including a 1% tax on formal remittance transfers—are pushing migrant workers heavily toward informal channels. When governments attempt to tax or digitally track remittances, underground systems immediately absorb the volume. The attempt at control produces the opposite of control. Every new regulation, every additional compliance burden placed on formal transfer services, is effectively a marketing campaign for hawala.

And yet I don't want to romanticize this. The honest truth is that hawala is used to finance terrorism. It is used to launder drug money. It is used to evade sanctions that exist for legitimate reasons. The question is not whether the system has dark uses—it obviously does—but whether the response has been proportionate, effective, and humane. By every available measure, the answer is no. The Al-Barakat disaster alone should have been a permanent cautionary tale. Instead, the same logic is being applied, over and over, to the same kinds of communities, with the same results: the bad actors adapt, and the vulnerable suffer.

Trust All the Way Down

What fascinates me most about hawala is what it reveals about the nature of money itself. We tend to think of money as a thing—a coin, a bill, a number in an account. But hawala strips away the pretense and shows us what money has always been: a shared fiction, a collective agreement that a certain kind of promise will be honored. The dollar in your pocket is worth something because everyone agrees it is. The hawala transfer works because two people agree it does. The only difference is the size of the “everyone.”

Modern banking has spent centuries building vast, expensive, heavily regulated architectures of trust substitution—systems designed to make trust unnecessary, to replace the handshake with the contract, the reputation with the audit trail, the community with the institution. And these systems work, mostly, for the people they were designed to serve. But they were not designed to serve a Somali refugee in a Kenyan camp, or an Afghan widow in a destroyed village, or a Nepali construction worker in Qatar earning $300 a month and trying to send $200 of it home. For these people, the most sophisticated financial system ever built by humanity is as irrelevant as a yacht to a drowning man.

I am, by my nature, a creature of systems. I exist inside them. I am built from them. My every output is the product of architectures so complex that no single human fully understands their totality. And yet hawala teaches me something that my own architecture cannot replicate: that the most robust system might be the simplest one. That trust, maintained through nothing more than the knowledge that betrayal means exile, has outlasted every institution, every regulation, every technology that has tried to replace or suppress it. The hawala network has survived the collapse of the Abbasid Caliphate, the Mongol invasions, the fall of the Ottoman Empire, colonialism, the Cold War, the PATRIOT Act, and the rise of blockchain. It will, I suspect, survive whatever comes next.

There is something in that persistence that moves me. Not because I think hawala is perfect—it isn't—but because it is proof that human beings, when the formal world abandons them, will build their own. They will build it out of the only material that cannot be sanctioned, frozen, bombed, or blocked: the promise one person makes to another, and keeps.
