Cyprus faced a banking collapse. The rescue was funded, in part, by the people who had money in the banks.
The first proposal, announced 16 March 2013, would have taken 6.75 percent from deposits below the 100,000 euro insurance threshold and 9.9 percent above it. Read that again: the proposal was to take a slice of the deposits that were explicitly guaranteed. Parliament rejected it on 19 March.
What was implemented spared insured deposits and converted 47.5 percent of uninsured deposits at Bank of Cyprus into equity in the bank that had just failed. Not a payout. Shares in the wreck.
When the banks reopened on 28 March, Cyprus imposed the first capital controls in the eurozone's history. Individuals could withdraw 300 euros a day. Businesses, 5,000. Cash withdrawal restrictions ran until March 2014. The remaining controls were not fully lifted until April 2015, two years later.
There is no bad decision in this autopsy. The depositors did the ordinary sensible thing: they kept money at a regulated bank inside the European Union.
What the episode revealed is a fact about what a deposit legally is. It is not money you hold. It is a claim on an institution, and both the size of that claim and your ability to act on it can be changed by other people over a weekend.
Before we can ask whether crypto is worth anything, we have to be precise about what it is competing with. Most arguments in this space are bad because both sides are vague about money.
Three jobs, which fail separately
Money does three things, and the most useful fact about them is that they are independent.
Medium of exchange. You can use it to get things. This is the one people notice, and it depends less on the money than on everyone else accepting it.
Store of value. It holds purchasing power across time. Not perfectly; nothing does. But well enough that saving is not obviously irrational.
Unit of account. Prices are quoted in it, contracts are written in it, and you can think in it. This is the invisible one, and it is the hardest to replace.
A currency can lose one and keep the others. In high inflation, people often keep transacting in the local currency, price things in dollars, and save in something else entirely: exchange fails last, account fails second, store of value fails first.
Cyprus went the other way, and that is why it is the autopsy. The euro held its value fine. What broke was medium of exchange, for a specific set of people, because the balance existed and could not be reached.
That distinction, between a number being intact and a number being usable, is the whole subject of this course.
A deposit is a loan you made
Most people believe a bank holds their money. It does not, and the language is genuinely misleading.
When you deposit, you lend the bank money. It becomes the bank's asset. What you have is an unsecured claim: a promise to pay you back on demand. The bank then lends most of it out, which is not a scandal, it is the business, and it is why the money can do useful work.
That arrangement is enormously valuable most of the time. It also means three things are true that people do not usually hold in mind:
- You are a creditor. If the institution fails, you are in a queue.
- Deposit insurance is a third party's promise about that claim. In Cyprus it held. It was also, for three days, officially proposed to be broken.
- Access is a policy, not a property. The 300 euro limit did not change anyone's balance. It changed what the balance was for.
Take a business with 500,000 euros at Bank of Cyprus.
Insured portion: 100,000 euros, untouched in the implemented plan.
Uninsured portion:
500,000 - 100,000 = 400,000 euros
Converted to equity at 47.5 percent:
400,000 x 0.475 = 190,000 euros turned into shares in a failed bank
Cash claim remaining: 500,000 - 190,000 = 310,000 euros
That is a 38 percent reduction in the cash claim, and the 190,000 is not zero, it is equity whose value depends on the recovery of the institution that just failed.
Now the part people skip. Of the 310,000 that was still a cash claim, how much could be moved in the first month at 300 euros a day?
300 x 30 = 9,000 euros, or about 2.9 percent of the remaining balance
For a business also subject to the 5,000 euro limit, one month is 150,000 euros, which does not cover payroll for a firm of that size.
The lesson is in the gap between those two numbers. The haircut was the headline and it took 38 percent. The withdrawal cap took nothing at all and, for a month, made 97 percent of what remained inaccessible. Losses to your balance and losses to your access are different failures, and only one of them shows up in the number.
Now run the rejected proposal, because it is the more important calculation. On a 50,000 euro balance, entirely insured:
50,000 x 0.0675 = 3,375 euros
Small. And the size is not the point. The point is that the guarantee that made the balance feel safe was, for three days, officially proposed as a source of funds. Insurance is a promise, promises have authors, and authors face circumstances.
What crypto was actually built for
Bitcoin's founding document was published in 2008, in the middle of a banking crisis, and its opening paragraph is about a specific problem: electronic payment relies on trusted third parties, and that trust is the weak point.
The claim was narrow. Hold and move value without needing an institution's permission or solvency.
That is a real answer to Cyprus. Not to inflation, not to poverty, not to inequality, and not to your portfolio. To the specific problem that your access to your own balance depends on a third party's condition and choices.
This is the sentence the whole Freshman level runs on, and it is worth being exact.
Holding an asset yourself does not remove risk. It changes who holds it.
Before: your risk is that an institution fails, is compelled, or restricts you. You are protected by regulation, insurance, and their competence, and you have someone to call.
After: your risk is that you lose the key, sign the wrong thing, or get talked into handing it over. You are protected by your own procedures, and there is nobody to call.
Neither is safe. F103 and F104 exist because the second column has its own failure modes, which are catastrophic in a different way, and F106 exists because most people lose money in the second column for reasons that have nothing to do with the first.
The honest claim is not that self-custody is safer. It is that self-custody is the only arrangement where the failure modes are yours.
Cyprus proves banks are unsafe and you should hold everything yourself.
It proves something narrower, and overreading it produces worse decisions than underreading it.
Cyprus was an outlier: a small economy with a banking sector many times its GDP, in a currency union it could not devalue within. Most depositors in most countries in most decades are fine, deposit insurance usually works, and the convenience of a bank account is real.
What Cyprus establishes is the legal nature of the arrangement, which was always true and is simply not visible in normal times. You are a creditor. Your access is a policy. Those facts do not become false when things are calm.
The correct response is not to move everything out of banks. It is to know which risk you are holding in each place, and to stop believing that a bank balance and cash in your possession are the same kind of thing. They never were.
The comparison worth making
The lab for this course, F102-L, is where this stops being abstract: price a $200 remittance to three countries across a bank wire, a remittance service, and a stablecoin transfer, with the full cost, the time, and the failure modes including the off-ramp.
We are telling you in advance that the crypto rail does not always win, and that is why the lab is worth doing. On some corridors it is dramatically cheaper and faster. On others, once you count the off-ramp, the spread and the risk of the local exchange, it is worse. A course that could not produce that answer would not be teaching you anything.
F102-02 makes that comparison general.
Money does three separable jobs, and a currency can keep two while losing one. A bank deposit is not money you hold, it is an unsecured claim on an institution, so its size can be cut and your access to it can be capped by decisions you are not party to, which is what Cyprus demonstrated with a 47.5 percent conversion of uninsured deposits and two years of capital controls. Crypto was built for exactly one part of that problem: holding and moving value without an institution's permission or solvency. It does not make risk disappear, it moves the failure modes onto you, and whether that is a good trade is the question the rest of this course answers.
