Moody's warns the tech giants' AI spending is straining their credit, bond investors are charging more to lend, and much of the debt is kept off the balance sheet — as yields climb, oil holds near $100, and a Fed decision looms.

Key takeaways

Moody's warned that the tech giants' huge AI spending is straining their credit, and bond investors this week began charging more to lend to them.
Much of the cost is kept off the balance sheet as $1.2 trillion in data-centre leases — obligations Moody's counts as debt anyway.
It lands as borrowing gets dearer everywhere: Treasury yields hit a multi-year high, oil holds near $100, and the Fed meets next week.

The bill for AI lands on the bond market

For two years the AI story lived in the stock market, where investors cheered every spending plan. This week it moved to the bond market, where the mood is colder.

Moody’s — a credit-rating firm that scores how safely companies can repay debt — warned Friday that “unprecedented” AI spending is straining the finances of the biggest tech firms [77]. The numbers are the reason. The firm projects the giants will spend about $785 billion on capital expenditure this year, and close to $1 trillion next year [77]. Capital expenditure, or capex, is money spent on physical assets like data centres and chips.

That breaks the old software formula. Software costs little to copy, so it threw off fat profits and clean balance sheets. AI needs warehouses of expensive, power-hungry servers, paid for now, with revenue arriving later [77]. Across the six largest “hyperscalers”, direct debt has reached roughly $460 billion [77].

The debt that doesn’t show up as debt

Here is the part worth slowing down on. To keep borrowing off their balance sheets, the tech giants are leaning on long-term data-centre leases rather than loans [77]. Those lease commitments have swelled to $1.2 trillion — and more than $820 billion of it is for centres not yet built [77].

A lease is a promise to pay rent for years. Economically, it is very close to a debt. Moody’s says it treats these commitments as “debt-equivalent liabilities” — real obligations, wherever they sit on the page [77]. The label changed; the money owed did not.

Bond investors have noticed. This week the spreads on the biggest names widened, meaning lenders now demand more reward to hold their bonds [11]. Meta lifted its spending guidance, raising fears the others follow [11]. The hyperscalers are on track to spend more on capex than they generate in cash by next year, one bank told clients [11]. One firm’s credit-default swap — a form of insurance against a company failing to pay — is back at a multi-year high [11].

Moody’s is careful here. Microsoft, Alphabet, Amazon and Meta still hold among the strongest balance sheets on earth, and no downgrade looks imminent [77]. The strain shows first at weaker names like Oracle, now on a negative outlook [77].

The cost of money, still climbing

The AI worry meets a broader one: borrowing is getting dearer for everyone. The 10-year Treasury yield touched above 4.7% on Thursday, its highest since January 2025, before President Trump’s second term began [1][7]. That benchmark helps set mortgage and loan rates. It eased slightly Friday to about 4.69% [1].

Next week the Federal Reserve, America’s central bank, meets. Most expect no change, but a few economists now float a surprise rate rise, and Fed Chairman Kevin Warsh faces a hard summer of spiking yields [9][27]. Overnight, Trump’s temporary 10% global tariff expired, and new levies of 10% to 12.5% replaced it, written to be harder for judges to strike down [70]. Tariffs tend to lift prices, which keeps rates high.

Oil back at $100

Crude is adding to the pressure. Brent oil held near $100 a barrel after Houthi forces attacked Saudi tankers in the Red Sea, and Trump weighed a “massive attack” on Iran [39]. Analysts do not expect the Strait of Hormuz, a channel that carries much of the world’s oil, to reopen until next year [47]. Dearer oil plus dearer money has revived talk of “stagflation” — weak growth and stubborn prices at once [26].

Deals and dividends

Away from the gloom, money kept moving. On Saturday South Korea’s SK Hynix and Samsung signed memory-chip supply deals with US tech firms, including Nvidia, worth about $950 billion over their life [56]. Paramount agreed to freeze its merger with Warner Bros. Discovery until as late as June 2027 while antitrust courts weigh it [59][16]. Kuwait’s state oil company sold and leased back its pipeline network for $16 billion to Blackstone, KKR and Brookfield [61].

Banks held steady. Bank of America raised its quarterly dividend 14% to 32 cents, its chief executive citing a return of spare capital [64]. Russia’s central bank cut its key rate a notch to 14%, caught between struggling businesses and stubborn inflation as the war grinds on [3][6]. And the European Central Bank said it will open a €50 billion euro-lending facility for foreign central banks from the autumn — a standing backstop for times of stress [73].

The thread

Pull the strands together and one story emerges. The price of money is rising, and the largest borrower in the world right now is the AI buildout. Whether that spending pays off is still an open question. What changed this week is who is asking it — not the cheering equity crowd, but the bond market, which has to be repaid.

02 · Lesson · why it matters

The debt you move off the page is still owed

Moving a debt off the books changes where it is recorded, not whether it must be paid — and the record is what onlookers trust.

A promise dressed as something smaller

The AI companies have found $1.2 trillion of obligation and tucked most of it out of sight.

They are building data centres at a furious pace. Someone has to pay for the buildings, the chips, the power. Rather than borrow the money outright — which would show up as debt — they sign long leases instead. They rent the centres for years. Those lease promises now add up to $1.2 trillion, and more than $820 billion of it is for centres not yet built.

On the balance sheet, a loan and a lease look different. In the world, they are almost the same thing: a stream of payments you are locked into for years, whether the AI bet pays off or not.

A lease is a loan in a different coat

Slow down on why this matters.

Borrow a billion dollars and you owe a billion, plus interest, and everyone can see it. Sign a lease worth a billion in future rent, and you owe roughly the same. But on the page it can sit quietly, described as a normal cost of doing business rather than debt.

The cash you must find each month is identical. The risk — that revenue arrives slower than the bills — is identical. Only the label moved. And a label is cheap to change. The obligation underneath it is not.

The arrangement pays, and it poses as neutral

None of this breaks the rules. Accounting has long treated many leases differently from loans, and that treatment looks like a plain technical fact.

But it is a choice, and it served the people who made it. For years the tech giants were praised as “fortress” companies with clean balance sheets and little debt. Part of that fortress was built by keeping obligations in the lease column instead of the debt column. The strength was partly a picture.

This week the picture met a colder eye. Moody’s, a firm that scores how safely companies can repay, said it counts these leases as debt anyway — obligations that bind the companies to years of rent. The bond market, whose job is to be repaid, began charging more to lend. What looked settled from one seat looked like hidden risk from another.

The move is everywhere once you see it

This is not a tech trick. It is one of the oldest moves in finance, and in life.

A government that does not want more debt on its books guarantees a private company’s loan instead — no borrowing, just a promise to pay if things go wrong. A household that will not take a mortgage signs a long car lease and a stack of buy-now-pay-later plans. A bank in 2008 parked its riskiest holdings in separate vehicles that sat off its balance sheet — until they didn’t.

Each time, the obligation is real. Each time, moving it changes where it is written, not whether it must be honoured. And each time, the tidy-looking version is the one most people trust, right up until it surfaces.

You are downstream of the hidden pile

This is not a spectator’s story.

The same bond market now re-counting the tech giants’ hidden leases is the one that sets the price of money for everyone. When lenders decide a large, quiet pile of obligation is real after all, they demand more to lend. That ripples out to mortgage rates, car loans, and the interest a government pays on its debt. Your pension fund very likely holds some of these company bonds. The re-pricing of a hidden obligation two thousand miles away can nudge the cost of your own borrowing.

We tend to trust the headline number — the debt on the page, the price on the screen, the balance in the account. The headline number is exactly what an arrangement is built to keep flattering.

What no single seat can see

From inside the company, the fortress was genuine — the debt column really was small. From the equity investor’s screen, the spending looked like ambition rewarded. Neither seat was lying. Each simply could not see the whole obligation from where it sat.

It took the bond market and the rating agency, looking from another angle, to add the hidden column back in. And even they see only their slice. No one holds the full balance sheet of the world in view. That is the humbling part: an obligation can be genuinely invisible from your seat and completely real from the next one. The safest way to read any tidy number is to remember it was written down by someone, somewhere they chose. Hold it a little more loosely for that.
