Read the tour

The whole tour as plain text and static diagrams — the same facts, the same ending, no animation. Every figure links to the record it came from, and the record names the edition it was read from.

Every square below is drawn the same size, and the dashed square inside it is the amount from the scene before, at its true area against this one. That is the comparison the tour makes as it pulls back, one step at a time. One scale across the whole page is not available: the largest amount here is 16,000,000 times the width of the smallest, which is a square either too small to see or too large to print.

A square drawn on its own as an outline is an example rather than a measured figure. A filled square is money somebody owes, and it carries a link to the entry it came from.

Each comparison divides the two figures as they are printed, so the division you can do on the page is the comparison. The squares are drawn from the amounts behind those figures, which differ from them by their rounding and no more, and how the numbers were chosen states the rule.

HistoricalHolland · Summer 1636 to early February 1637

Tulips: the legend grew too

The contract changes hands while the bulb stays in the ground.

The market broke in 1637. The story about an entire country ruined by gardening grew later. You've probably repeated it.

Agree to buy a bulb before it's delivered, and the flower can get cheaper while your agreement keeps the old price.

Anne Goldgar follows those speculative contracts and the sharp rise in some bulb prices before the market broke in early February 1637. Her research describes a much smaller trade than the familiar national-disaster story.

Fact or folklore?

Supported: some bulb prices rose sharply, much of the trade ran on contracts for later payment and delivery, and the market broke in early February 1637.

Not supported: that everyone took part, or that the episode destroyed the Dutch economy. The archival work behind this card rejects both.

No numeric price benchmark is approved for this episode, and none is shown: the archival work cited here supplies no market-price series, and it rejects the familiar story of universal participation and national ruin. A promise to pay for a bulb is not the same thing as the bulb's resale price, and neither is a modern bank loan.

HistoricalQuoted in US dollars · November 2021 to mid-June 2022

Bitcoin: same coin, different tag

Somebody has changed the price tag. The coin is the same.

If you borrowed to buy it, there's still a lender to pay.

Sell the coin and the lender still wants paying. If the sale brings less than you owe, you have a loan and no coin. Buying outright means no lender, and the price can still drop.

The rounded prices come from the ECB's November 2022 article. Its negative outlook is the authors' view, not proof of permanent collapse. The BIS finding about limited wider financial spillovers also concerns 2022.

Price per bitcoin, at its peak
about $69,000

Price per bitcoin

mid-June 2022
Implied fall
about 75%
between those two observations · our arithmetic
1 − 17,000 ÷ 69,000 = 75.4%
Where does debt enter?

Holding one bitcoin is not a promise to repay a dollar loan. Owning a thing and owing a thing are different relationships.

Borrowing to buy an asset is what adds the obligation: the loan slip stays the same size whatever the asset's tag says next.

Rounded narrative observations, not one exchange's exact daily close, and not the whole 2022 peak-to-trough history. The first figure is a peak the source names, not a representative price for that November, and the fall between the two is our own arithmetic on the source's two rounded figures rather than a decline the source states. The cited article's broader interpretation is strongly negative; it is used here for these two dated figures only, not as proof of a permanent collapse.

HistoricalUnited States · a statement about IRS tax debt · Disclosed January 2010

Nicolas Cage: an unexpected appearance

Nicolas Cage's IRS bill, disclosed in January 2010. A name we recognize on the paperwork.

The accountant gets top billing.

Cage disclosed approximately $14 million owed to the IRS in January 2010. Later reporting described that tax bill and separate creditors. It's a large pile even before the other paperwork arrives.

His roughly $6 million repayment recollection in 2023 is a separate account, not a replacement for the earlier disclosure.

Owed to the IRS, as stated
about $14,000,000
disclosed January 2010

A historical, approximate, self-reported figure, attributed to a January 2010 statement and reaching us through a blog post quoting a magazine. It is not his current debt, not a verified lifetime maximum and not a record of any kind. No court filing or tax record states $14 million; the largest amount tied to actual recorded documents is about $13.3 million in federal tax liens for 2002, 2003, 2004, 2007 and 2008, which is a different measure and a different set of years. In a 2023 interview he said he had paid it all back and put the total at about $6 million — his own later account of the same debt, not a second, separate one. Both numbers are his; they are thirteen years and one repayment apart, and neither is audited.

HistoricalUnited States · a bond issuance backed by music royalties · 1997

Bowie bonds: fixed income

In 1997, Bowie raised money against future royalties from his music.

The accountant can leave the record on.

Bowie's 1997 bonds raised $55 million against royalties from his earlier music catalogue. Prudential bought them.

The songs could keep earning; the deal let him receive money up front instead of waiting for those royalties. The bondholder had a reason to care what was playing.

Raised by the bond issuance
$55,000,000
1997
Flip the sleeve

$55 million was raised up front, in 1997.

Royalties from the earlier catalogue were what supported repayment. The figure is the money raised, not a measured rate of cash flow.

A 1997 financing issuance, not an overdue personal bill and not a sign of financial distress. The citation is a 2002 entry on the artist's official site, which does not describe the issuance in its own words — it quotes a Q magazine piece. That is one hop further from the event than a citation normally implies, and the entry's comparison of the bonds' performance with government stock is its own claim, not adopted here. What happened next is settled and better documented than the entry: Moody's rated the issue A3 at the outset and cut it to Baa3 in March 2004, one grade above speculative, citing weaker recorded-music sales and a downgrade of the guarantor; the bonds were repaid in full at maturity in 2007. The drawn royalty notes illustrate the arrangement, not a measured cash-flow rate.

HistoricalBritain · 1720

South Sea: change the certificate

A government claim goes into the exchange. A share in the South Sea Company comes out.

The company also participated in the trade in enslaved people.

A government-security holder in 1720 could hand over that certificate for South Sea Company shares. The new certificate went in the same drawer. The holder now had an ownership interest instead of the same debt claim.

When the shares crashed, the holder lost money, and a falling share price is not the government paying anyone back.

The company also participated in the trade in enslaved people. Its financing can't be separated from that business.

Turn the certificate over

Face up, a government security. It is debt: a fixed promise to pay, held by a creditor. This is what a holder brought to the exchange.

Turned over, a share. It is equity: a claim on ownership, worth whatever it fetches next. This is what the holder took away.

A claim went in and a share came out. Exchanging one for the other changed what holders held. It did not simply erase the government's obligation, and a later fall in the share price was not the same amount of unpaid government debt.

No share-price endpoints and no present-day equivalent are approved for this episode, so none appear. The South Sea Company also held a right granted in 1713 to supply enslaved people to Spanish colonies; that is recorded here and in the source text, and it is not drawn. The engraving reference in the source list is a late-18th-century print after Hogarth, not an image made during the 1720 event and not evidence for any 1720 price.

HistoricalLondon and overseas sovereign lending · 1822 to 1825

London bonds: an impressive brochure

The prospectus is quite detailed about a government that doesn't exist.

Poyais was invented. The land and its inhabitants weren't.

The prospectus is on a London desk and the borrower is overseas. One is easier to inspect.

The New York Fed describes speculation and poor information in the lending boom. It reports Latin American bond prices roughly halving by summer 1825. Those are resale prices. The principal owed didn't halve, and it isn't a formal index of every London bond.

Poyais took the paperwork further. The land and its inhabitants were real and the issuing state was made up. It was one fraud within the wider panic.

Latin American bond prices, in this historical account
Roughly halved
by summer 1825
Price or promise?

The promise is printed on the certificate: what is owed, on what terms, by when. It does not move because the market moved.

The price is what somebody will pay today to hold that promise. A price halving is not principal being cancelled, and it is not a forecast of what will eventually be repaid.

A bond is a written promise to pay that can itself be bought and sold, which is the idea this card introduces. The halving is an approximate historical generalization from the cited account, not a defined index for all London bonds and not a dated series; no numeric index observations exist for it here. It is not a principal write-off and not a recovery rate. Poyais is one swindle among many and is not the explanation of the whole crisis; the invented state is the fraud, not the land or the people said to live there.

AI: no ending written yet

The next rack is still on paper.

The racks need paying for before anyone knows what they'll earn. A company can use its cash or borrow, including through private credit. Either way, the equipment arrives before the answer.

The BIS research asks whether earnings can sustain the build-out. Its September 10, 2026 speech describes anticipated AI-related capital expenditure by the five largest big-tech companies across 2025 and 2026.

That spending plan isn't an account of OpenAI's or Anthropic's current debt, and it doesn't say how the boom ends.

Capital expenditure is spending on assets over a period. The figure on this card is a two-year plan, part of it still ahead.

Debt is an obligation outstanding on a date. Different measure, different shape, different question.

An equity valuation is an assessment of what ownership is worth. It is neither money owed nor money spent.

I'd like to count the mortgages twice. For emphasis.

What this counts

National outstanding credit-report balances under the New York Fed framework. These categories share a date and can be assembled into their reported total. They are not the components of the different BIS U.S. household figure.

Housing: the house and the loan

Nobody touched the house. It's worth less anyway.

In this example, selling it wouldn't cover the loan.

Imagine selling the house and handing the proceeds to the lender. In our example, the sale brings $70, but the loan is $80. There's $10 left to find.

Before the price drop, the home was worth $100 and the owner had $20 in equity. After it, equity is negative $10. These are hypothetical figures, with payments, interest, and loan changes held still.

The actual mortgage crisis also involved lending, securitization, collateral, and wider financial stress.

Illustrative example; no payments, interest, or loan changes. These are our arithmetic figures, not U.S. historical data, and not a claim about national house prices.
VariableBeforeAfter the price change
Hypothetical home value$100$70
Hypothetical mortgage balance$80$80
Equity, value minus loan$20−$10
Step between before and after

Before: the home is $100 and the loan is $80. Equity is $20.

After: the home is $70 and the loan is still $80. Equity is minus $10. The borrower owes $10 more than the home is worth. The house is the same house; only its price tag changed.

The mortgage slip did not move. Real obligations can change later, through payments, refinancing, modification or legal process. None of that happens in this instant comparison, which is built to show one thing only.

The $100 / $80 / $70 figures are an arithmetic illustration written for this card, not observations and not a figure from the cited source. There is no claim that U.S. homes fell exactly 30%, and this is not a foreclosure or recovery model. Not all mortgage lending was subprime, and the crisis had no single cause. The loan is held fixed by construction.

Describe the picture

The six household categories join: mortgages, home-equity lines of credit, student loans, auto loans, credit cards, and other balances.

The cards, student loans and mortgages were already in this total. You've seen them twice. It counts them once.

The Ledger

Every balance goes in once. It is my one rule, and I enjoy it.

Describe the picture

The U.S. federal-debt field appears beside a long receipt that runs to the edge of the scene.

CONTINUED ON NEXT PLANET

The U.S. federal government's bill needs a longer receipt. You hold one end. The other end is somewhere past the desk.

What this counts

Federal gross debt, including holdings within the government and debt held by the public. Its perimeter differs from the European general-government comparisons.

24. Global public debt

Describe the picture

The view widens to a field representing global public debt. A small Earth comes into view.

Every government at once, in the IMF's 2024 figures. A small Earth has wandered into the picture.

What this counts

IMF public and private nonfinancial debt for 2024. A separate financial-sector layer and other obligations outside that scope are excluded. The figure comes from the global dataset, not the sum of this tour's examples.

25. Global private nonfinancial debt

The private nonfinancial-debt field appears beside the public-debt field. Household and business figures stand within the private side.

Households and nonfinancial businesses owe the other part. That's you again, and the shop on the corner.

The two fields form the $251 trillion 2024 total. The little Earth and distant desk remain in view.

The number was already true on page one. All that changed is how much desk it takes to show you.

Describe the picture

The same field of tiles as the total before it, and a few of the IOUs in it have turned over on their tethers. Their backs are blank: the paper says an amount and does not say who holds it.

The same total, drawn again from the other side. Every tile is a trillion dollars somebody is owed, and no tile says who.

Whoever holds the claim gets paid. You look around. They're here somewhere.

Borrower and lender share a planet. They don't share an account.

Fictional epilogue

Describe the picture

At the Earth yard sale, the alien takes the paperweight and leaves an IOU for the whole ledger. Payment is due EVENTUALLY. The worker opens the note as the ship leaves.

The desk goes outside. The sign goes up. The ledger stays open at the total.

Somebody arrives, reads the ledger, and stamps their own clipboard. An internal matter, apparently.

They pick up the paperweight. It has a tag on it now. It says make an offer.

You point at the tag. They copy the ledger's total onto a note, all fifteen digits.

You take the note. They take the paperweight. No money changes hands, in either direction.

You open the note beside the ledger and look up. The ship is already leaving.
