At a glance
- The US government owes about $39.9 trillion, and crosses $40 trillion within days.
- The 30-year Treasury yield peaked at 5.3371% on Tuesday, its highest since June 2007.
- Private foreign buying of US government debt fell more than 40% over the past year.
- Foreign central banks went further and sold a net $10 billion of Treasuries in June alone.
- Borrowing costs rose in Japan, Germany and France too, so this is not only Washington's problem.
- The dollar drifted near multi-month lows even while it paid more, which is what risk compensation looks like.
- It lands on households as a 6.75% mortgage and diesel up 48% on a year ago.
Forces in play
US debt is near $40 trillion, and every dollar of it has to be refinanced by finding a fresh buyer.
Private foreign purchases of US debt fell more than 40% in a year, and foreign central banks sold a net $10 billion in June.
Brent crude reached $91 a barrel after the US-Iran ceasefire expired on Monday, keeping the fear of rising prices alive.
Fund managers are the most bullish since 2022 on one Bank of America measure, holding just 3.5% cash - the opposite of what bond buyers are signalling.
The rout paused on Wednesday: the 30-year yield slipped back to about 5.28% and gold steadied near $4,342 an ounce.
How it unfolded
- Monday The US-Iran ceasefire expires; June data on foreign Treasury holdings lands
- Tuesday The 30-year yield peaks at 5.3371%, its highest since June 2007
- Wednesday Yields ease to about 5.28%; the dollar sits near multi-month lows
- Later Wednesday The Federal Reserve publishes minutes of its July meeting
Where this points
Watch whether foreign buying steadies in the next monthly Treasury data - a second sharp drop would mean the pullback is a trend rather than a summer wobble.
Full briefing
Someone stopped queuing for America’s debt
The United States government owes about $39.9 trillion, and is expected to cross $40 trillion within days.
The yield on the 30-year Treasury bond is the interest the government pays on money it borrows for thirty years. It peaked at 5.3371% on Tuesday, the highest since June 2007.
A bond’s yield rises when its price falls. So a rising yield is a crowd of buyers asking for more before they hand over their money.
Fresh figures show who stopped queuing. Monday’s Treasury data covered June. Net buying of US Treasury notes and bonds by private foreign investors fell to $16.6 billion, the lowest since January.
The official buyers went further. Foreign central banks and reserve managers were net sellers of nearly $10 billion in June alone.
Two recent auctions showed what that costs. A sale of 10-year notes cleared at 4.683%, the highest in 19 years. The 30-year sale stopped at 5.216%, a 25-year peak.
“The overall market environment is definitely requiring Treasury to pay more to borrow,” said Zachary Griffiths of CreditSights.
It is not only Washington
Long-term borrowing costs rose across the rich world on Tuesday. Japan’s 10-year government bond yield reached a three-decade high just under 3%.
Three pressures are pushing all of them at once. Governments are borrowing heavily. Inflation is not going away. And technology companies borrowing to build artificial-intelligence data centres are competing for the same pool of savings.
Oil is the accelerant. A US-Iran ceasefire expired on Monday, and Brent crude climbed for a fourth day to $91.28 a barrel.
“Investors are no longer taking on faith that (government) spending gets brought under control,” said Nigel Green, chief executive of the advisory firm deVere Group. He added that they are now pricing the risk that it does not.
The strange part: pay up, and the dollar still falls
A currency that pays more interest normally attracts money and strengthens. This week the opposite happened.
The dollar index measures the currency against six major peers. It sat at 99.65 on Wednesday, near multi-month lows.
Higher pay and a weaker currency together is what it looks like when lenders want compensation for risk, not a better return.
Some central banks are choosing metal instead. Spot gold traded at about $4,342 an ounce on Wednesday.
Countries that cannot issue the money the world wants have a harder job. India’s central bank spent another day defending the rupee, which touched 95.6825 per dollar, its weakest since 30 July.
Where this lands on a household
The 10-year Treasury yield sets the tone for American mortgages. It was 4.739% on Tuesday, against below 4% before the Iran war began at the end of February.
The average 30-year fixed mortgage rate was 6.75% on Tuesday, on Mortgage News Daily’s daily survey.
Consumers should not expect any meaningful decline in mortgage rates, said Lawrence Yun, chief economist at the National Association of Realtors.
Capital Economics expects US home sales to slow to around 4.7 million this year. That would be the weakest since 2011, with house prices ending the year flat.
Fuel bites too. A gallon of diesel cost $5.46 on Tuesday, up 48% on a year ago, according to AAA.
Two markets, two moods
Share investors are not worried. Bank of America’s global fund manager survey found sentiment at its third most bullish reading since 2022.
Bond investors disagree. The 10-year yield is up almost 80 basis points from its February low.
Shares took the point on Tuesday. Wall Street’s main indexes fell for a third session.
The Federal Reserve publishes minutes of its July meeting on Wednesday. Chair Kevin Warsh has offered few clues since that meeting, so the minutes carry more weight than usual.
Elsewhere
Britain’s labour market kept softening. Unemployment held at 4.9%, where economists had expected 4.8%.
US import prices fell 0.4% in July, against forecasts of a 0.1% rise, on cheaper fuel. Over the year they are still up 5.9%.
India’s Nifty 50 companies posted average profit growth of 18% for the June quarter, a ten-quarter high. Nineteen sectors beat estimates.
Klarna’s shares fell about 20% before the opening bell, after the buy-now-pay-later firm said its finance chief and marketing chief were both leaving.
And America’s three largest cinema chains backed David Ellison’s $111 billion merger of Paramount and Warner Bros. Discovery, a deal several states say will hurt them.
02 · Lesson · why it matters
What it is worth to be the money everyone wants
The issuer of money everyone wants gets real goods for a promise it prints itself - and that discount was never a law of nature.
How it works
- Making money costs almost nothing
- Spending it buys real things
- The gap between the two is the issuer's profit
- The world wants your money, so it lends to you cheaply
- But supplying the world means borrowing more
- And that borrowing is what makes the world doubt you
The twist
The right to issue the money everyone wants is paid for by running the deficits that make everyone doubt it.
Where you've seen this
A shopkeeper's gift cards
cards bought and never spent are money he already holds for free
A landlord's deposits
he keeps your cash, earns on it, and only owes it back later
Frequent-flyer miles
the airline prints its own currency and passengers queue to earn it
A dominant app store
everyone must hold its credits, so it sets the terms of the exchange
The catch
The privilege is being repriced, not revoked - there is still no market deep enough to replace it, so the world keeps lending, just dearer.
Full lesson
The queue got shorter
The largest borrower on earth was asked to pay more this week. Not much more, and not by anyone in particular. Just a few thousand separate lenders, each deciding independently that the old price was no longer enough.
Underneath the numbers sits a question most people never think to ask. Why was the price ever so low?
The oldest profit in money
Printing a banknote costs a few cents. Spending it buys a hundred dollars of real things. The gap between those two numbers is the profit of being the one who issues the money.
It has a name: seigniorage, after the medieval lord who took a cut of every coin struck in his mint. Modern versions need no paper. A central bank creates a balance out of nothing, buys a government bond with it, and collects interest on that bond for as long as it holds it. Something was made from nothing and now pays a wage.
This is a different thing from a commercial bank writing a new deposit into your account when it lends you money. That deposit is a private promise, and it disappears again when the loan is repaid. What follows is about state money, and about who wants it.
Now do it for everyone
Oil is quoted in dollars. Trade is invoiced in them. Central banks keep them for a bad week. So the world holds an enormous quantity of American paper - not out of admiration, but because it needs the thing.
That demand is itself a loan. A foreigner holding your currency has handed over something real and taken back a claim you print. A foreigner holding your bonds is lending at a rate they would offer nobody else, because your paper is the one everybody accepts.
A French finance minister named this in the 1960s: an exorbitant privilege. The description holds. The issuer gets goods now, in exchange for a promise it makes itself.
The bill inside the privilege
Here is the catch, and it is not a small one. To supply the world with your money, more of it must go out than comes back. That means buying more from the world than you sell to it, and borrowing to cover the difference.
So the privilege requires exactly the behaviour that makes people doubt the money. Robert Triffin set this out around the same time, and it has not aged. Supply too little and others start building an alternative. Supply too much and confidence drains away. There is no setting that holds both forever.
This week you can see both halves at once. The debt stack sits near forty trillion dollars because the deficits kept running. And the buyers who used to absorb that debt are asking for more, or quietly buying gold instead.
The arrangement nobody signed
It looks like plain fact that a barrel of oil is priced in dollars. That a firm in Sao Paulo borrows in dollars, and a central bank in Jakarta keeps dollars for an emergency. It is not a fact of nature. It is an arrangement, and arrangements have beneficiaries.
The honest other half is that it also serves the people inside it. A market that deep is one you can leave in a hurry without moving the price. Nothing else comes close, which is why the world grumbles and keeps lending. A privilege can be a genuine service at the same time.
The other side of the counter
Watch what happens to a country that cannot issue the money the world wants. India’s central bank has spent days holding the rupee inside a narrow band, using dollars it had to earn by selling something real. South Africa’s currency slips whenever the world turns nervous, and nobody asks South Africa first. They can make their own money freely. Dollars they must go and get.
The reader is inside this too. The rate the United States pays on a thirty-year loan sets the tone for a mortgage in Ohio, a car loan in Manchester, a company loan in Mumbai. When the world’s safest borrower is charged more, everyone standing behind it in the queue is charged more as well. Nobody consulted the queue.
What cannot be seen from here
None of the people selling this week coordinated with each other. Each was answering a narrow question about their own holdings, on their own timetable, with their own reasons. What they added up to has a name only in hindsight.
The privilege was not revoked this week. It was repriced, by a few basis points, in a direction nobody chose and nobody can yet measure. That is usually how the terms of a very old arrangement change: not at a meeting, but in the space between one auction and the next.

The Issuer's Dilemma
Rehearse the trade-off inside issuing the world's money - supply too little and others build an alternative, supply too much and belief drains away.
04 · Hope · carry this
Trust in a shared thing is not a switch that flips. It gets renegotiated a few points at a time, by people who still expect to be trading with each other next year.
