Part 1: Your money isn't kept safe
There is a sentence buried deep in the terms and conditions of virtually every financial institution, every crypto exchange and every fintech app that processes payments on your behalf. It reads, in one form or another, like this: when you deposit funds with us, those funds become our property, and you become an unsecured creditor.
Read that again. An unsecured creditor. Not an account holder. Not a customer whose money sits in a ring-fenced vault with your name on it. A creditor, in the same legal category as a supplier waiting to be paid after a company goes bankrupt.
This is not a conspiracy theory. It is contract law, and it has been standard practice in the financial industry for centuries. The arrangement is called custodial finance, and it is the invisible architecture underneath every savings account, every brokerage account, every digital wallet operated by a centralized company. You give them your money, they take legal control of it, and they give you a promise in return.
For most of history, that promise was good enough. Banks were regulated. Deposit insurance existed. The system was slow and expensive, but it was predictable. Then something changed.
The illusion became visible
The 2008 financial crisis was the first major crack. Lehman Brothers collapsed and took client assets with it. MF Global followed in 2011, freezing customer accounts that customers believed were segregated and protected. In Cyprus in 2013, the government simply reached into accounts above a certain threshold and took a percentage as a bailout levy. No warning. No recourse.
The pattern is older than the modern era. Sweden experienced it directly in the early 1990s. A decade of deregulated lending had allowed Swedish financial institutions to build enormous exposure to a property market that collapsed sharply in 1990 and 1991. Nordbanken and Gota Bank failed outright. Forsta Sparbanken and several regional savings institutions required emergency state intervention. Depositors with amounts above the guarantee threshold lost money. Those below it survived only because the Swedish government took the extraordinary step of issuing a blanket guarantee of the entire banking system, a decision that cost taxpayers the equivalent of four percent of GDP. The individuals who lost were not speculators. They were ordinary account holders who had trusted the system with their savings.
Argentina has experienced custodial failure on a scale that destroyed entire generations of savings. The 2001 corralito, the name Argentines gave to the government decree that froze all accounts overnight, trapped an estimated forty billion dollars in deposits for more than a year. When accounts were eventually unfrozen, withdrawals were converted from dollars to pesos at an artificially imposed rate that immediately lost sixty to seventy percent of its value. People who had saved in dollars their entire lives walked away with pesos worth a fraction of what they had deposited. The financial institution had not failed in the conventional sense. The government simply decided that the depositors’ dollars were more useful as an instrument of sovereign policy than as savings belonging to their owners. Argentina repeated a version of this sequence in 2019 and has maintained currency and capital controls in various forms ever since. For a significant portion of the Argentine population, the domestic financial system is not a place to store wealth. It is a place where wealth goes to be confiscated.
Across sub-Saharan Africa, institutional failure has been routine enough to constitute a structural feature of the financial landscape rather than an exceptional event. In Nigeria, the 2009 banking crisis saw eight of the country’s largest institutions require emergency Central Bank intervention after a combination of reckless lending and insider fraud wiped out capital bases entirely. Customers at Oceanic Bank, Intercontinental Bank and Afribank lost access to funds for extended periods, and several institutions were ultimately wound down. In Zimbabwe, the financial system collapsed so completely in the late 2000s that the central institution printed denomination notes in the trillions before abandoning the currency altogether, erasing the savings of an entire population in the process. In Kenya, Imperial Bank was placed under receivership in 2015 after the discovery of a decade-long fraud that had diverted depositor funds to undisclosed lending. Customers recovered less than half their deposits after years of legal proceedings. In each case, the depositors had done nothing wrong. They had simply placed their trust in an institution that had full legal control over their assets and chose to use that control in ways the depositors never consented to.
The crypto industry, born partly in reaction to 2008, was supposed to fix this. It did not. It replicated the same custodial model in a new wrapper. When FTX collapsed in November 2022, roughly a million customers discovered that the company had been lending out, investing and effectively gambling with assets that customers believed they owned outright. The funds were gone. The legal process to recover them took years and returned only a fraction.
Celsius Network. Voyager Digital. BlockFi. The list of custodial crypto platforms that collapsed and stranded customer funds runs long. In every single case, the root cause was identical: a company held assets on behalf of customers and made decisions about those assets that customers never consented to, because the fine print said they could.
The nature of the problem
The issue is not corruption, though corruption exists. The issue is structural. When you hand your assets to a custodian, you create a situation where one party controls the asset and a different party has the interest in the asset. Those two parties are always in tension. The custodian has every incentive to use the asset productively, meaning to deploy it for their own purposes. The customer has every incentive to believe the asset is sitting safely and available on demand. Both cannot be simultaneously true.
Banks resolve this tension through regulation and deposit insurance, which caps the amount protected at levels that were reasonable in the 1970s and have not kept pace with real wealth. Crypto exchanges resolved it by simply not resolving it. They took the customer's assets, issued a database entry in return, and called it ownership. The database entry was not ownership. It was a claim.
The difference matters enormously. An owner can move their asset at any time, to any destination, without asking permission. A claimant depends entirely on the willingness and solvency of the counterparty.
Why this matters more now
The custody question has always mattered. But it matters more today for three reasons that are converging simultaneously.
First, the volume of assets flowing through digital platforms has grown to a scale where individual exposure is significant. A decade ago, most retail crypto holders had small positions. Today, many people hold meaningful portions of their savings in digital form.
Second, the rate of platform failure has accelerated. The combination of interest rate rises, leverage and market volatility has been lethal for platforms built on the assumption of perpetual growth. The stress tests are no longer theoretical.
Third, and perhaps most importantly, there is now an alternative that is practical, accessible and does not require technical expertise to use. The alternative is called non-custodial finance. It is the subject of the next article in this series.
But before we get there, it is worth sitting with the fundamental point. The system you have trusted with your money does not think of that money the same way you do. You think of it as yours. The system thinks of it as a liability on a balance sheet, to be managed, deployed and, in extreme circumstances, withheld.
That is not paranoia. It is the law. The question is whether you want to continue accepting it.
