The yield on 10-year Japanese government bonds touched 3.00% today. The last time it was there was 1996.
That happened on the same day the German yield reached its highest since 2011 and the French its highest since 2008. And on that very same day, the US bond market barely moved.
That gap between the global headline and what is actually happening in Washington is this piece's starting point.

Where the Drama Actually Was
| 10-year yield | Level | Context |
|---|---|---|
| Japan | 3.00% | highest since 1996 |
| Germany | 3.335% | highest since 2011 |
| France | 4.194% | highest since 2008 |
| UK | 5.207% | |
| US | about 4.76% | highest since January 2025 |
The Japanese move is the real outlier. The 30-year there stands at 4.19%, and the Bank of Japan's policy rate is 1.00% - so the gap between the policy rate and the long yield is enormous.
And the policy rate itself is not routine either: the Bank of Japan raised it to 1.00% on 16 June 2026, its highest level since September 1995. At the following meeting, in July, it held there in an eight-to-one decision - with board member Hajime Takata proposing a rise to 1.25%.
Japan is unusually sensitive to this move because of the scale of its government debt. When yields rise, the cost of rolling that debt rises with them, and a country that carried large debt at near-zero rates for three decades discovers an entirely new cost.
And in the US - the Move Is Small, but Its Composition Changed
Care is needed here, because the headlines speak of a global storm while the American data tell a quieter story. These are the official figures from the US Treasury:
| Maturity | 27 Aug | 28 Aug | 31 Aug | Total |
|---|---|---|---|---|
| 2 years | 4.20% | 4.34% | 4.34% | 14 bp |
| 5 years | 4.38% | 4.48% | 4.49% | 11 bp |
| 10 years | 4.67% | 4.73% | 4.75% | 8 bp |
| 30 years | 5.19% | 5.22% | 5.25% | 6 bp |
This is not a collapse. It is a crawl of one to three basis points a day.
But now look at the two bold rows, because that is where the finding sits.
On 28 August, the day of the Fed Chair's Jackson Hole speech, the two-year yield jumped 14 basis points while the 30-year rose just 3. That is rate pricing: the market said near-term policy would be tighter, and barely changed its assessment of the long run.
On 31 August the picture inverted. The two-year did not move at all - 4.34% and again 4.34% - and the 30-year rose another 3 points.
That is no longer the same engine. When the short end stands still and the long end keeps climbing, the market is no longer pricing interest rates - it is pricing the compensation it demands for holding long-dated debt over time. The short end belongs to the central bank. The long end belongs to deficits, issuance supply and uncertainty.
Three Forces Cited as Explaining the Move
The first is energy, and it is the immediate one. A barrel of Brent crossed $90 yesterday against the background of events in the Persian Gulf. In the European inflation release published today, energy inflation jumped to 14.3% from 10.3% in July, and the headline rose to 3.3%.
The second is the scale of sovereign debt. US federal debt crossed the $40 trillion mark in mid-August, standing at $40.05 trillion - barely four and a half years after it passed $30 trillion. And Japan's ministries are expected to request a record budget.
The figure that turns this from background into engine is this: interest alone now costs more than $1 trillion a year, and is currently the second-largest line in the federal budget - behind only Social Security. More debt means larger issuance, and larger issuance requires a higher yield to find a buyer - which in turn raises the interest on the next tranche of debt.
And one detail deserves noting, because it joins two subjects we have covered separately: the threshold was crossed months earlier than forecasters expected, and among the reasons cited is the revenue lost from the invalidated tariffs.
And the third is the one that bears directly on a subject we cover here regularly: among the factors cited for pressure on the bond market is a wave of debt issuance by the large cloud companies, to fund artificial intelligence infrastructure.
There is a loop here worth describing explicitly, without overstating it.
AI companies are raising debt at large scale to fund data centres and chips. Issuance on that scale competes for the same capital that funds governments, and contributes upward pressure on yields.
And higher yields compress precisely the value of assets whose profits are expected years out - that is, those very same companies.
I am not claiming this is the main driver of rising yields; it is cited alongside deficits and energy, and I cannot quantify its share. What I am saying is that the connection exists and is explicitly noted, and that both of its ends touch the same stocks.
What the Market Is Pricing Now
The implied probability of a Fed rate rise at the 15-16 September meeting stands at about 68%, against roughly 40% last week.
In Europe the picture is sharper still: the market fully prices a rise to 2.50% on 10 September.
So two central banks are priced as tightening within a fortnight - which explains why the short end of the curves has already made its move, and why the current motion is at the long end.
And in Equities, to Keep Proportion
There is no crash here. As these lines are written the S&P 500 is down about 0.5%, the Dow about 0.34% and the Nasdaq about 0.9%. Yesterday the S&P fell 0.30%, and August as a whole closed up 2.6% on the index and 3.9% on the Nasdaq.
What does stand out is the composition of the decline, and it is consistent with the story in the curve: asset managers Blackstone and KKR each fell about 4%; Marvell, Intel, Oracle and Tesla about 3%; Alphabet 2.21% and Nvidia 2.03%. Against them, Merck rose 1.84%, Johnson & Johnson 1.63% and Chevron 1.49%.
Long-duration assets down, defensives and energy up. That is characteristic behaviour for a market pricing higher rates over time, not for a market in fright.
הזווית שלי
דעה אישית של אילן אברמוב - לא ייעוץ ולא המלצה
I wrote here two days ago, after the Jackson Hole speech, that the long end of the curve had barely moved and that this was evidence of anchored inflation expectations. I also said that was what I would be watching.
Within two trading days that changed, and I think it is worth saying so plainly rather than leaving it implied. The line that was stable began to move, and the line that moved has stopped.
What I take from it is not a rate forecast but a distinction about reading a curve. A move at the short end and a move at the long end are not the same piece of news, even when they look identical on a chart. The first says what the market thinks the central bank will do. The second says what the market demands as compensation for uncertainty - about deficits, about supply, and about distant inflation. A central bank can answer the first. It answers the second far less well.
And on Japan - I think that is the figure easiest to ignore and least advisable to. Thirty years of near-zero yields created habits across the world, not only in Tokyo, because Japanese capital sought returns outside Japan. A domestic yield of 3% changes that calculation. If it stays there, this is not a Japanese event.
And what I will track from here is narrow and specific: the gap between the two-year and the 30-year. If it keeps widening while the short end stands still, that says the market has moved to pricing long-run risk - and that is a bigger change than any single rate decision.
(It is important to stress: this is my personal opinion only, and nothing herein constitutes a recommendation to take any action.)
