Quick Answer
This was one of the more consequential weeks of the quarter for markets, with the Fed’s policy meeting, surging oil prices, and a multi-decade Treasury yield milestone all converging within a five-session stretch. The week opened with the Dow, Russell 2000, and broader market falling as Brent crude topped $101 a barrel on Wednesday, September 9, continued declining through Thursday as Brent hit $105, partially recovered Friday on better-than-feared inflation and oil data, then resumed falling into Monday and Tuesday as the 10-year Treasury yield climbed to its highest level since 2007, reaching 5.041%, just ahead of the Fed’s Wednesday decision.
Day by Day Through the Week
TheStreet’s running daily coverage provides a clear picture of how each session built on the last. Wednesday, September 9 saw the Dow and Russell 2000 fall as Brent crude passed $101 a barrel for the first time since July, alongside Apple’s foldable iPhone launch event dominating headlines the same day. Thursday, September 10 brought a fourth consecutive daily decline as Brent oil climbed further to $105 a barrel. Friday, September 11 offered some relief, with the S&P 500 and Dow recovering as both the August inflation report and oil data came in better than markets had feared. That recovery didn’t hold: by Monday, September 14, the Dow had posted its biggest weekly loss since March, and Tuesday, September 15 saw continued weakness as the 10-year Treasury yield hit its highest level since 2007.

The Numbers That Defined the Week’s Close
CNBC’s coverage of Tuesday’s session, the last full trading day before Wednesday’s Fed announcement, shows where markets stood heading into the decision: the Dow Jones Industrial Average closed at 52,093.11, down 328.09 points (0.63%); the S&P 500 ended at 7,585.73, down 0.45%; and the Nasdaq Composite settled at 25,981.57, down 0.78%. Fed funds futures traders were pricing in a roughly 92% likelihood of a rate hike heading into the announcement, according to CME’s FedWatch tool — among the most confident market pricing has been all year regarding a specific Fed outcome.
Oil Was the Week’s Persistent Undercurrent
Crude prices provided the throughline connecting nearly every session this week. Brent crude’s climb from $101 to $105 a barrel over just two trading days reflected escalating Middle East tensions, and that energy-price pressure fed directly into inflation expectations, which in turn fed directly into Fed rate-hike odds — a genuinely tight feedback loop that made oil price movements almost as closely watched by equity traders this week as the Fed-specific data itself.
A Notable Divergence: AI Stocks Held Up Better Than the Broader Market
CNBC’s Tuesday coverage flagged a specific, somewhat counterintuitive pattern: even as the broader S&P 500 and Nasdaq declined, several AI-connected names gained ground, including Coherent, AMD, and Qualcomm. This came the same week that prominent AI industry leaders, including OpenAI’s Sam Altman and Anthropic’s Dario Amodei, publicly discussed the case for slowing frontier AI model development over safety concerns. Rather than reading this as bearish for AI stocks, Bank of America strategist Benjamin Bowler’s note to clients argued the opposite: that AI’s rising potential alongside its risks reinforces the case for continued exposure to the sector.

Bank of America’s Specific Stumble
Not every individual stock move traced back to the macro backdrop. Bank of America fell 5% on Monday specifically after CEO Brian Moynihan told investors that third-quarter investment banking fees would likely decline more than 10% from a year earlier, with trading revenue expected to come in roughly flat — a reminder that company-specific earnings guidance can still produce outsized single-stock moves even during a week otherwise dominated by macro-level news.
Precious Metals Didn’t Provide Their Usual Hedge
CNBC’s coverage noted gold and silver both declined earlier in the week even as equities fell, with spot silver down more than 3% to $62.54 an ounce and spot gold down roughly 1% to $4,306.19 an ounce. That combination, both risk assets and traditional safe havens falling together, is consistent with a market broadly positioning for higher rates across the board, since elevated rates increase the opportunity cost of holding assets that don’t pay yield.
What Made This Week Genuinely Unusual
- Three major, simultaneous storylines: Oil prices, Treasury yields, and Fed policy expectations all moved in tandem rather than one dominating while others stayed quiet, making the week’s daily moves harder to attribute to any single cause.
- A multi-decade bond market milestone: The 10-year Treasury yield’s move to its highest level since 2007 is a genuinely rare occurrence worth noting on its own, independent of the Fed decision it preceded.
- Sector divergence within an overall down week: AI-connected stocks showing resilience even as the broader market fell suggests investor conviction in that specific theme remained intact despite the week’s broader risk-off tone.
Frequently Asked Questions
What drove markets down this week?
A combination of surging oil prices (Brent crude climbing from $101 to $105 a barrel), rising Treasury yields reaching their highest level since 2007, and elevated odds of a Federal Reserve rate hike all weighed on stocks throughout the week.
How did major indices perform this week?
The Dow posted its biggest weekly loss since March, with the S&P 500 and Nasdaq also declining across most sessions, closing Tuesday at 52,093.11, 7,585.73, and 25,981.57 respectively.
Why did AI stocks perform better than the broader market this week?
Despite AI industry leaders publicly discussing safety concerns around frontier model development, analysts largely interpreted the commentary as reinforcing the case for continued AI investment rather than a warning sign, and several AI-connected stocks gained even as the broader market fell.
What is the significance of the 10-year Treasury yield reaching its highest level since 2007?
It represents a genuinely rare, multi-decade milestone that reflects both shifting Fed rate expectations and inflation concerns tied to geopolitical tensions, and it directly affects how investors value future corporate earnings relative to safer bond yields.
