Long yields did the tightening
Last week the Fed raised rates. This week the bond market tightened further without it. The US 10-year yield crossed 5% and briefly touched 5.23% on Friday, its highest since 2007. Germany's 10-year reached its highest since 2009, and Japan's touched 3.12%, the highest since 1996. On the worst day, 10-year yields in the US, UK, France, Italy and Spain each rose by roughly 13 to 15 basis points. By Friday, futures priced about a 64% chance of another Fed hike in October.
The more useful explanation is supply. A weak Treasury auction mattered more than any speech. Central banks have stopped buying, and Japanese insurers can now earn around 3% at home. The buyers who remain can decline to buy, and they price accordingly. This weakens the assumption that cheaper oil brings yields down. Brent fell early in the week, and yields rose anyway. Flash PMIs in the euro area and the US beat expectations, with US employment and input prices rising alongside output. Two Fed speakers also placed inflation in services rather than energy. None of that gave bonds a reason to recover.
The MOVE index, which tracks bond-market volatility, jumped about 30%, its largest weekly rise since April 2025. Higher volatility limits how much risk funds may carry, and the effect tends to reach equities with a lag. Long yields also set how heavily future profits are discounted. US utilities lost close to 4% on the week, real estate more than 2% and financials almost 2%.
One index, two stories
The Nasdaq set records while bonds sold off. Early adoption data for Meta's Muse assistant lifted the chip complex, and AMD passed a trillion dollars in market value. Micron, up roughly 284% this year, added about 5% after results. Global equity funds took in $44bn. Goldman Sachs estimates that AI investment drives nearly half of S&P 500 earnings growth this year, and that its contribution may fade in 2027 even if spending continues.
The financing side is where 5% yields matter. Oracle, among the most debt-funded AI builders, lost about 7%. SoftBank paid its richest yields yet on more than $11bn of high-yield debt. Akamai's $11.6bn Anthropic contract came with a warrant for up to 5% of Akamai, so part of that revenue is effectively paid in shares. The stock gave back most of its opening jump, which suggests the market applied a discount.
Oil: relief without resolution
Brent traded between roughly $97 and $99 for most of the week and remains up around 60% this year. Diesel margins stayed extreme, and physical barrels traded at a widening premium to futures, which points to real shortage. Saudi Arabia restarted its East–West bypass pipeline at low rates, although Sunday reports listed it among disrupted routes. Friday's 3% drop rested on a reported Iranian offer to reopen Hormuz, which Trump rejected on Saturday. Crude reopens without that premise, and Aramco is still withholding October term barrels from some European refiners.
The ECB expects inflation near 3% and growth below 1%, and Lane sees the target in view only from mid-2027. Cheaper oil would help European households and industry more than long bonds. France, with its spread over Germany above 100 basis points, carries the most refinancing risk.
Smaller threads
The US–China tariff truce was extended to 10 January, about fifteen weeks, and the summit produced no export-control outcome. The Fed is reportedly preparing to raise thresholds for its strictest bank oversight, which would lower compliance costs for regional banks and likely encourage mergers. Rate worries outweighed that this week, though regional banks may be where it eventually shows. Norges Bank and South Africa hiked, while China pledged looser policy with the yuan at multi-year highs.
Going into next week
Quarter-end falls on Wednesday. After a quarter in which equities beat bonds, balanced and pension funds typically sell stocks and buy bonds. That can briefly support long bonds without changing their direction. The Treasury plans more bill issuance in October, and with the Fed's reverse repo buffer largely drained, funding markets have less spare cash. Any strain would likely show there first. Euro-area flash inflation follows, then US payrolls on Friday. With immigration down, weak hiring no longer clearly signals weak demand, so a soft number means less than usual. Auction demand and the France–Germany spread are likely better guides this week than index levels.
