Fed delivers its first hike since 2023 as Warsh's hawkish press conference rattles stocks, with the BOJ set to follow tomorrow
The Federal Reserve raised its benchmark rate by 25 basis points to 3.75-4.00% on Wednesday, a unanimous 12-0 decision and the central bank's first increase since July 2023. The move itself was fully priced in, but Chair Kevin Warsh's press conference was the market-moving event: all three major indices were trading higher heading into the 2pm decision, then reversed hard once Warsh began speaking, with the S&P 500 closing down 0.45% at 7,551.81, the Dow off 1.21% (631 points) to 51,461.90, and the Nasdaq essentially flat at 25,978.42 after clawing back from a steeper intraday drop. Warsh told reporters he'd be "hard pressed to describe broad financial conditions as restrictive," a clear signal the Fed isn't done tightening, and the updated dot plot showed most officials penciling in at least one more hike this year — futures now put the odds of a second 25bp move at the 28-29 October meeting near 51%, up sharply from just 18% a week ago. The 10-year Treasury yield held close to the 5% line it breached for the first time since 2007 earlier this week, and the dollar index climbed 0.6% to its strongest level since late July.
The Bank of Japan adds a second tightening pulse tomorrow: its two-day meeting concludes Friday, and all 52 economists surveyed by Bloomberg expect a 25bp hike to 1.25% — which would be Japan's highest policy rate since 1993 and its sixth hike since ending ultra-loose policy in 2024. On the oil side, the supply picture that's been feeding this inflation cycle showed its first signs of easing: Saudi Arabia is now routing additional crude through the Strait of Hormuz with US military assistance and arranging ship-to-ship transfers to Asian refiners near Oman's Sohar port, cushioning the hit from the still-damaged East-West pipeline, which Aramco is reportedly aiming to restore to half capacity within days and full capacity within about six weeks. Brent eased to $105.81/bbl and WTI to $102.14 on Thursday as those concerns lifted slightly, though both remain well above pre-crisis levels.
02Stock market & economy
Asian markets took the Fed's tightening in stride overnight: Japan's Nikkei 225 rose 0.87% and the Topix gained 0.71% even with a BOJ hike now a near-certainty for Friday, South Korea's Kospi added about 1%, while Hong Kong's Hang Seng slipped 0.73% and mainland China's CSI 300 fell 0.36%. European trading was muted Thursday morning, with the Euro Stoxx 50 essentially flat near 6,385 and the AEX holding around the 1,096 level it closed at earlier this week. Gold remained pinned below $4,300/oz, close to a six-week low, as the hawkish-Fed, stronger-dollar narrative continues to outweigh any safe-haven bid from either the Gulf oil disruption or Wednesday's equity wobble.
For the unhedged USD sleeve (MSCI World ETF, S&P 500 ETF, High Dividend Yield ETF), Wednesday's hawkish press conference is the more important signal than the hike itself: a Fed that isn't finished tightening keeps upward pressure on the dollar, a tailwind for these funds' EUR-translated returns, but also keeps real yields rising against the mega-cap tech names that dominate their weightings — the same names most exposed to the "AI capex versus bond yields" tension described below. High Dividend Yield ETF's value and energy tilt remains the natural offset if oil stays elevated. For AEX index ETF and EURO STOXX 50 ETF, Shell's leverage to firmer crude is the direct read-through, while tomorrow's BOJ hike is a reminder that global tightening is now a two-central-bank story, not just a Fed one — a modestly firmer yen and dollar-strength dynamic that nets out as a small headwind for European exporters.
03Also in the news
The Bank of Japan's Friday decision, flagged above, is the next major event risk after today's Fed meeting — a hike is essentially locked in, but roughly a third of surveyed economists expect the BOJ to signal another move as soon as December, which would mark an unusually fast tightening pace for a central bank that only ended negative rates in 2024. Russia-Ukraine diplomacy has produced no fresh developments since Monday's Trump-Putin call: the proposed Abu Dhabi meeting between envoys still has no confirmed date, and Russia's Donbas-withdrawal precondition remains the unresolved sticking point Kyiv continues to reject.
A structural shift in the Treasury market is now getting explicit attention from Fed officials: Warsh himself named "competition for capital from hyperscalers funding the capex boom" as one of three drivers behind the rise in long-term yields since July, alongside a strengthening economy and geopolitics — the clearest sign yet that the AI-bond boom detailed below has moved from a market curiosity to a factor in actual monetary policy.
04Off the beaten path
how AI hyperscalers quietly started "reverse crowding out" the US Treasury
For decades, the textbook worry about heavy government borrowing was "crowding out" — that a flood of Treasury issuance would soak up so much investor capital that private companies would struggle to borrow, or pay punishing rates when they did. This year the dynamic has effectively run in reverse. US tech companies, which historically sold around $61 billion of bonds a year, had issued close to $500 billion by July, with more planned before year-end, as hyperscalers race to fund AI data-center buildouts. Nomura estimates that borrowing by the largest tech firms alone now equals roughly 25% of the Treasury's net issuance to private investors — five times its share in 2025. Every dollar that flows into a Microsoft, Meta, or Oracle bond is a dollar not flowing into a Treasury auction, and with issuance on both sides climbing, yields have had to rise to clear the market on both — a dynamic Fidelity's Jurrien Timmer says has already drawn the attention of both the Treasury Secretary and, per his own Jackson Hole remarks, Chair Warsh.
The read-through for a diversified portfolio is genuinely two-sided rather than a simple negative. The same hyperscaler capex boom that's pushing up the long end of the yield curve — and therefore raising the discount rate applied to every growth stock MSCI World ETF, S&P 500 ETF, and High Dividend Yield ETF hold — is also the earnings driver behind those same companies' stock prices; mega-cap tech is simultaneously the source of the yield pressure and the thing being valued against it. Nothing about this calls for repositioning today, since none of the existing funds can be tilted around a bond-issuance trend without also giving up the earnings exposure driving it, but it's a genuinely new mechanism worth tracking: if yields keep climbing for supply-and-demand reasons unrelated to Fed policy, rate cuts (whenever they eventually arrive) may do less to bring long-term borrowing costs down than markets currently assume.
