Treasury Eased Yields. The Fed Kept the Door Open.

GOOD MORNING, Washington gave the bond market some relief Wednesday, but not a clean policy signal. Treasury doubled the size of buybacks for long-dated bonds after the 30-year yield hit a 19-year high, pulling yields sharply lower and helping stabilize risk assets. Hours later, Fed minutes showed many policymakers still think another rate hike may be needed if inflation does not move back toward 2%. The result is an unusual tug-of-war: fiscal authorities are trying to calm long-term borrowing costs while monetary policy is still willing to tighten. Meanwhile, Google and Marvell added another twist to the AI-capex story by tying a massive stock warrant to future custom-chip purchases.

MARKETS | TLDR

Treasury intervention pulled long yields lower: The 30-year Treasury yield fell from Tuesday's 5.34% peak to about 5.18% after Treasury doubled buybacks for 10- to 30-year securities to at least $4 billion per operation.
The dollar weakened as the bond selloff cooled: Lower long-term yields pushed the dollar down against major currencies and helped gold rebound, showing how quickly Treasury-market stress had begun spilling across asset classes.
Equities stabilized after Tuesday's tech shock: Wall Street recovered from the prior session's semiconductor-led selloff as lower yields and large healthcare gains offset lingering concerns over Iran, inflation and AI valuations.

POLICY TUG-OF-WAR

Treasury Is Fighting the Long End. The Fed Is Still Fighting Inflation.

The Treasury Department doubled planned liquidity-support buybacks for 10- to 30-year securities to at least $4 billion per operation after the 30-year yield hit 5.34%, its highest level since 2007. The announcement drove the long bond yield down by almost 10 basis points before it settled near 5.18%. Treasury said the larger purchases were designed to improve liquidity in markets where investors were offering significant amounts of older debt back to the government.

The move matters because long-term yields have become a constraint on nearly every major market narrative. They raise the government's own interest bill, tighten mortgages and corporate financing, and increase the discount rate applied to growth stocks. But the size of the intervention is small relative to the market it is trying to influence: Treasury is adding at least $14 billion of extra buybacks this quarter against a Treasury market worth more than $32 trillion. The program can improve liquidity without changing the deficits, inflation risk or supply of new debt that pushed yields higher in the first place.

The policy tension became clearer later Wednesday. Minutes from the Fed's July meeting showed that "many" policymakers thought a rate hike would be needed if inflation failed to move down toward 2%, while several had already been ready to tighten at that meeting. Treasury is trying to prevent disorderly pressure at the long end; the Fed is still willing to make short-term money more expensive. Markets now have to price both at once.

CUSTOM SILICON

Google Just Put $12 Billion Behind Marvell's AI Roadmap

Marvell granted Google a warrant to buy nearly 59 million shares at $206.58 each, representing about $12.2 billion at the exercise price, as part of an expanded custom-silicon partnership. The agreement covers AI inference accelerators, storage controllers, network-interface chips, memory-interface controllers and near-memory compute tied to Google's TPU ecosystem. Marvell shares surged after the disclosure.

The structure is more important than the headline value. Google is not simply placing a chip order; it is giving itself an equity-linked payoff if the partnership scales. That aligns the hyperscaler's economics with the supplier it needs to expand custom AI infrastructure and gives Marvell a potentially much larger revenue path if Google exercises the warrant as commercial milestones are met. It is another example of AI customers using strategic financing and ownership incentives to secure infrastructure capacity.

The broader signal is that custom silicon is becoming a more important complement to merchant GPUs. Nvidia still dominates general-purpose AI acceleration, but hyperscalers increasingly want chips optimized for their own workloads, power budgets and economics. Google's deeper Marvell relationship therefore does not necessarily mean less AI spending. It means more of that spending may be distributed across specialized accelerators, networking and memory architecture — widening the set of companies that can participate in the buildout.

HEADLINES

Fed minutes turn more hawkish: Several policymakers were prepared to hike in July and many said tightening may be needed if inflation does not decline, keeping September firmly in play despite the relief in long-term yields.
Moderna's cancer-vaccine result changes the mRNA narrative: A personalized Moderna vaccine combined with Merck's Keytruda met both major goals in a late-stage melanoma trial, the first such Phase 3 success for a personalized mRNA cancer vaccine and a potential validation of the platform beyond COVID.
Target's turnaround keeps gaining traction: Target raised its annual sales forecast for the second time this year as price cuts and refreshed merchandise improved demand, though nearly $1 billion of tariff refunds boosted quarterly profit and complicates the headline comparison.
Iran keeps oil risk embedded: Brent traded near a three-week high as Washington and Tehran gave conflicting accounts over the Strait of Hormuz, keeping the possibility of another energy-driven inflation shock in the background.
Healthcare briefly becomes the market's growth trade: Moderna more than doubled intraday and Merck jumped sharply after the melanoma data, lifting the S&P 500 healthcare sector to a record and showing that market leadership can broaden quickly when a credible earnings catalyst appears outside AI.

UPCOMING

Walmart earnings — August 20: Walmart will provide the cleanest near-term read on U.S. household demand after Target improved its outlook, especially as higher gasoline prices compete with discretionary spending.
Alibaba earnings — August 20: Alibaba's report will test whether AI and cloud demand are translating into profitable growth or simply pulling forward another wave of infrastructure capex.
U.S. flash PMIs — August 21: Activity and price data will help determine whether resilient growth justifies the Fed's more hawkish July discussion or whether the economy is beginning to soften under higher borrowing costs.
Nvidia earnings — August 26: Nvidia remains the next major test of AI infrastructure demand, but Marvell's Google deal shows investors should also watch how hyperscalers are diversifying spending across custom silicon and networking.

DEEP INSIGTHS

FOMC Minutes — July 28-29, 2026

The minutes are the best source for understanding why the Fed and Treasury can appear to be moving in opposite directions without actually contradicting each other. Treasury is addressing market liquidity and borrowing mechanics; Fed officials are focused on persistent inflation and were increasingly willing to discuss a more restrictive policy stance.

Marvell's Google Warrant Filing

The filing shows exactly how the strategic relationship is structured. Google's warrant covers up to 58.97 million Marvell shares and is connected to a broad set of custom products around the TPU ecosystem, making it a useful primary-source example of how hyperscalers are tying supplier economics directly to future AI infrastructure deployment.
