 The Long Bond Says No Plus: the US-Iran ceasefire expired and oil moved about 40 cents. |
Good morning, and welcome to Tuesday. The most important number out of New York yesterday wasn't an index level. It was the yield on the 30-year US Treasury bond, which nudged up to roughly 5.30% — the highest since 2007. Shares took the hint, the S&P 500 off 0.52% and the Nasdaq Composite down 0.32%.
The odd part is that two-year yields have been falling while the 30-year climbs, so this isn't a market bracing for a hot economy. It has looked at how much the US government wants to borrow for 30 years and decided to charge more for the privilege. Elsewhere, the ceasefire between the United States and Iran lapsed with nothing to replace it, and oil moved about 40 cents.

The 30-year Treasury yield is at a 19-year high, and the economy isn't the reason
The long bond rose a few basis points on Monday to about 5.30%, its highest since June 2007 and within reach of the 5.44% it hit in the opening act of the global financial crisis. The 10-year followed, up nearly seven basis points to just over 4.70%. Higher long-term rates make future profits worth less today, so shares gave ground.
What is actually pushing the long end up. Three things, none of them a booming economy. The Treasury is selling a great deal of long-dated debt to fund a deficit nobody in Washington is trying hard to shrink. Inflation has stopped falling, with July's consumer price index at 3.4% a year and core at 2.5%, both above the Fed's 2% target. And the traditional buyers of 30-year paper — pension funds, insurers, foreign central banks — aren't turning up in the size they used to. The tell is the curve: over the past month 30-year yields rose about 13 basis points while two-year yields fell about 12. Investors will lend for two years happily enough. They want paying properly to lend for 30.
That matters here too: long US yields anchor long-term borrowing costs almost everywhere, part of why New Zealand and Australian two and three-year wholesale rates keep grinding higher with both central banks on hold.
What to watch the Fed publishes its July minutes on Wednesday, and three members voted to raise rates at that meeting. But the minutes argue about the next few months, while the long bond is asking a harder question about the next few decades. The Fed sets the short rate; it doesn't set this one. |

A ceasefire between the US and Iran expired, and the oil market shrugged
The 60-day memorandum signed in June lapsed on Monday with talks deadlocked and the Strait of Hormuz still effectively shut, as it has been since late February. Brent rose 0.4% to a shade under US$89 a barrel and West Texas Intermediate sat near US$82. For a waterway that normally carries a fifth of the world's crude, that is a relaxed response.
Where the missing barrels have been coming from. Storage tanks. The International Energy Agency counted a 69-million-barrel fall in global oil stocks in July alone, and 410 million barrels drained between late February and the end of July, taking inventories below 7.9 billion barrels for the first time since April 2025. Supply is running 6.3 million barrels a day below a year ago, with 8.3 million shut in across the Gulf. High prices have also done their usual work of killing demand, and the agency expects consumption to fall 1.6 million barrels a day this year. Drivers are still paying for it: US petrol was 24.6% dearer in July than a year earlier.
The catch a stockpile is a cushion, not a supply source, and it only works once. The IEA now sees a 1.8-million-barrel-a-day shortfall this quarter, more than double its forecast a month ago. The oil market is calm because someone has been quietly emptying the pantry, and there is less in there every week. |

Nvidia will guarantee US$105 billion of somebody else's data centre, and wanted to do more
Nvidia, OpenAI and SoftBank's SB Energy announced the PORTS-Pike Technology Campus in Pike County, Ohio on Monday. SB Energy builds and owns it, OpenAI leases it for 20 years, and Nvidia backs as much as US$105 billion of the land, power and buildings for the first phase — 4.25 gigawatts, with an option on 3.75 more. The first 800 megawatts is due in 2028, and the campus will run about 1.5 million Nvidia chips. The shares rose 0.5%.
What Nvidia is really promising. Not to build anything. To guarantee the lease and power payments, so if OpenAI can't cover the rent, Nvidia does. This is vendor financing with extra steps: the chip seller underwrites its customer's ability to house them. It is also smaller than the version that leaked days earlier, which ran to as much as US$250 billion across the full campus. Shareholders made their discomfort clear, and Monday's version covers roughly the first half. Paying for the chips is a separate, larger conversation.
Chief executive Jensen Huang, asked whether this is circular financing — money looping between a supplier and its customer, making demand look sturdier than it is — said Nvidia is using its scale and long-term visibility to secure capacity, and covers portions of the payments rather than the whole cost. He reckons OpenAI could take about US$600 billion of Nvidia compute through 2030.
The real signal the interesting number isn't the US$105 billion, it's how much smaller it is than what leaked. For two years the AI buildout has been financed by anyone with a balance sheet, almost nobody asking who is on the hook. Somebody asked, and the commitment halved. |

Wrapping up
No central bank decisions this week, so the Fed's July minutes are the main event, at 2pm Wednesday in New York — 6am Thursday in New Zealand, 4am in eastern Australia. Three officials voted for a quarter-point rise then; the question is how close they came to taking anyone with them. US housing data lands midweek, jobless claims Thursday.
The American retailers do the rest of the talking. Home Depot reports before Tuesday's US open, with analysts looking for about US$4.71 to US$4.73 a share on roughly US$47 billion of revenue; comparable sales are the line to find, since they strip out new stores. Target and Lowe's follow Wednesday, Walmart Thursday. Closer to home, BHP's full-year result lands before the ASX open this morning, where CommSec's consensus is a US$2.10 full-year dividend and the payout ratio on underlying profit decides it. A GlobalDairyTrade auction settles overnight, Australia's wage price index is out Wednesday at 11.30am AEST, and July employment lands Thursday.
The kiwi and the Aussie both firmed against a softer US dollar, taking USD/NZD to 1.6954 and USD/AUD to 1.4077, the Aussie above 71 US cents for the first time since early June. Both ride one trade: American rate-rise bets have faded while the RBA holds at 4.35% with the door open to another hike, and traders price a quarter-point RBNZ rise on 2 September.
