The August Producer Price Index landed hot on Thursday: +0.4% month-over-month and +5.4% year-over-year, with final-demand energy up 4.2% and diesel fuel alone up 24.1% in a single month. That one line accounted for more than a third of the rise in goods prices. Core PPI was tamer at +0.2% MoM (a tick under the +0.3% consensus) and +4.6% YoY, and July's flat reading was revised up to +0.1%.

Markets repriced immediately. CME FedWatch now shows roughly a 60% probability of a 25 bp hike to 3.75–4.00% at the September 16 FOMC, with Kalshi near 57% and Polymarket closer to 49%. Barclays is calling for two hikes by year-end. The setup was already tilted: Chair Kevin Warsh flagged 12-month PCE at 3.7% at Jackson Hole, three FOMC members dissented in favor of a hike in July, and last Friday's payrolls printed +162K against a 55K consensus with unemployment steady at 4.1%, weakening the labor-market case for a hold.

That leaves today's 8:30 ET CPI as the tiebreak. July printed 3.4% headline and 2.5% core, dead on consensus, and settled nothing. A print at or below 3.4% likely buries the hike; a re-acceleration toward 3.6% makes it live. Either way, the dot plot that arrives with Wednesday's decision tells you whether September is one hike or the start of a cycle.

Senate Republicans released a revised, 630-page Digital Asset Market Clarity Act on Thursday, four days before a September 15 cloture vote on the motion to proceed. Sen. Cynthia Lummis says the text absorbs more than 114 provisions requested by Democrats, including a new requirement that "non-decentralized" trading protocols, where an identifiable group controls the code, register with the CFTC, plus language confining the DeFi provisions to spot and cash digital-commodity transactions to placate tribal governments worried about prediction markets.

The arithmetic is unforgiving. Cloture needs 60 votes; Republicans hold 52, so at least eight Democrats must cross. Politico reports the latest draft has no Democratic support, and the ethics section (barring officials from issuing tokens, enforced by DOJ, sunsetting January 2029) is largely unchanged despite being the sticking point over Trump's crypto wealth. Polymarket's 2026 passage odds have slid from 82% in February to 17–19% now.

For holders and builders, the stakes are the two provisions that survive only if the bill does: a statutory right to self-custody and a safe harbor shielding non-custodial developers from money-transmitter liability. Treasury Secretary Bessent and White House czar David Sacks are pushing for passage by month-end; Lummis leaves Congress in January. Failure doesn't mean a pause. It means agency rulemaking with no statutory floor.

Coinbase and payments-infrastructure provider Moov announced a partnership Thursday to embed stablecoin acceptance, settlement, and real-time funding into the systems of more than 1,000 community banks and credit unions. The integration runs on Coinbase's Payments API and custodial wallets plugged into Moov's existing platform, so a small institution can offer consumer payments, merchant acceptance, and payouts without building any crypto infrastructure of its own.

The pitch is cost, not ideology. Citizens Bank of Edmond CEO Jill Castilla said her small-business customers want lower interchange costs and faster settlement, which is exactly the wedge stablecoins have against card networks and ACH. The same day, MoneyGram launched a stablecoin-backed Visa card in Colombia, another sign the payments layer is being built regardless of the Clarity Act's fate.

Strategically, this completes Coinbase's shift from crypto venue to embedded infrastructure. PNC and JPMorgan (July 2025) and Citi (October 2025) came first; Moov gets Coinbase into the long tail of US banking in one contract. For COIN, it's recurring, non-trading revenue, and it extends stablecoin distribution into a channel the large banks don't own, just as the fight over stablecoin yield plays out in the Senate.

A Chinese research team published a quantum circuit (arXiv:2607.13816) that would break secp256k1, the signature curve behind Bitcoin and Ethereum, with 835 logical qubits, the lowest estimate on record. The benchmark stood at 2,124 in 2020, fell to roughly 1,193 at EUROCRYPT 2026, and is now 835: a 60% reduction in about four years, achieved entirely through better circuit design rather than new hardware. It also undercuts Google Quantum AI's March 2026 estimate of about 1,175.

No machine can run it. The best fault-tolerant systems today operate around 94 logical qubits, Google's Willow chip has 105 physical qubits, and the attack requires millions of error-corrected gate operations. The concern is trajectory: hardware capability and algorithmic requirements move independently, and 2026 alone has produced three major algorithmic drops.

Exposure isn't uniform. Coins in legacy pay-to-public-key outputs or reused addresses, where the public key is already on-chain, are the first target when hardware arrives; unused SegWit and Taproot addresses require a harder attack. Bitcoin's defense, BIP-360's post-quantum address types, remains a draft with a testnet implementation since March and no activation timeline. A soft fork plus a migration window takes years. This paper is the argument for starting the clock now.

US spot bitcoin ETFs posted −$120.2M in net outflows on Wednesday, their second straight red session after Tuesday's −$46.6M. ARK 21Shares' ARKB led the exit at −$78.0M, Grayscale's GBTC shed $27.2M, and BlackRock's IBIT gave back $19.5M; Morgan Stanley's MSBT was the only notable buyer at +$4.5M. September is still +$603.3M month-to-date on the strength of a $730.9M session on September 3, but the tone has shifted with PPI and hike odds.

The pullback follows the best month of 2026. August brought $3.52B of inflows across 16 of 21 sessions, including a nine-day streak from August 17–27, and lifted total ETF assets from $76.3B to $99.6B. That erased two-thirds of the year's deficit, cutting YTD net outflows from $5.29B to $1.77B. Bitcoin rose roughly 25% in the month before Warsh's Jackson Hole speech knocked it from $81,455 to a $76,877 low on August 28.

Price has gone nowhere since. BTC trades near $77,200, down about 1.2% on the day, with ETH around $2,450 and SOL at $100. The $80–81K zone has capped every breakout attempt this year, and with CPI this morning and the Fed on Wednesday, flows are the tell: a return to inflows on a benign print says August was accumulation; continued redemptions into a hike say the ETF bid is macro-conditional.
