    Weekend Edition · Aug 8 — Yen rescue, Fed hold, and a week of…

    Weekend Edition — the week in review. • The US and Japan jointly intervened to defend the yen for the first time in nearly three decades — a rare coordinated move that signals major-power alarm over currency weakness and ripples through global carry trades and dollar… • The Fed held rates on Monday and the Dow dropped over 2%, its worst session of 2026 — markets had priced a dovish pivot, and the hold forced a sharp repricing of rate-cut expectations. • A Coldcard hardware wallet vulnerability could cost holders up to 2,000 BTC — roughly $130 million — undermining self-custody confidence and potentially accelerating flows toward custodial Bitcoin ETFs.

    Aug 7 — SpaceX selloff, Google exits, Korea bear market

    • SpaceX shares fell 14% after its first earnings report revealed a sixfold jump in capex, mostly toward AI — investor fatigue with hyperscaler spending is now hitting private-market giants. • Jeff Dean, Sanjay Ghemawat, Quoc Le, and Oriol Vinyals left Google to found Discovery Loop — the exit of four AI legends sent Alphabet down over 5% and reshapes the top of the AI stack. • SK Hynix and Samsung dragged Korea's Kospi down 4.6%, extending its decline from the June peak to 31% — a bear market in a key AI supply-chain hub with spillover risk for global tech.

    Aug 6 — Amazon at $3T, SpaceX earnings, VC dry spell

    • Iran threatened strikes on Gulf states if the US takes military action in the region — raising escalation risk along Persian Gulf oil shipping routes and putting crude prices and broader risk sentiment on watch. • Palantir jumped 29% after beating earnings estimates and SpaceX posted $7.8B in revenue against a $6.8B estimate in its first-ever earnings report — both results reinforce the AI-enterprise trade ahead of a $101B SpaceX share… • A firmware exploit in Coldcard hardware wallets drained as much as $114M — the largest hardware-wallet breach on record — with analysts expecting the incident to push investors toward regulated Bitcoin ETF custody rather than…

    Aug 5 — Equities rally, SpaceX earnings, Boeing certified

    • US stocks surged Tuesday — Nasdaq +2.5%, S&P and Dow each +~1.75% — driven by strong earnings including Palantir and easing oil below $76 a barrel. • SpaceX posted its first-ever quarterly results well above expectations on Starlink and compute deals, while Boeing jumped 8% after the FAA certified the 737 MAX-7 after nearly a decade of review. • Coldcard's firmware vulnerability has confirmed losses of up to $130M across thousands of addresses, while Stripe is reportedly in talks to acquire AI routing startup OpenRouter for ~$10B.

    Aug 4 — Yen intervention, Treasury supply, and Amazon's milestone

    • The US and Japan jointly deployed ~$34B to defend the yen in their first coordinated currency intervention in ~15 years — a move that could unwind carry trades and reshape rate expectations across Asia. • Treasury raised its Q3 borrowing estimate to $739B, well above prior forecasts — the added supply could lift long-end yields and tighten financial conditions at a moment when the Fed's rate-hold vote was already split. • A seed-generation flaw in Coldcard hardware wallets has drained over 1,000 bitcoin from thousands of wallets, with losses near $114M — the breach puts cold-storage security under fresh scrutiny across the crypto industry.

    Aug 3 — US-Iran de-escalation, Fed dissent, and AI spending…

    • Trump announced a halt to strikes on Iran after preliminary deal parameters were reached — the de-escalation drove oil down more than 4% to ~$81 and broadly reduced geopolitical risk premiums. • The Fed held rates at 3.5–3.75% but three members dissented, and Q2 GDP slowed to 1.5% annualized from 2.1% — a divided committee and weakening growth leave rate-cut timing genuinely uncertain ahead of Tuesday's July payrolls… • Meta fell 10% on higher AI spending plans while a cold-wallet attack hit 4,500 Bitcoin addresses for ~$89M and an Iran-linked exchange allegedly routed $676M through Binance — investor patience with AI capex is thinning and…

    Weekend Edition · Aug 1 — Fed dissent, oil spike, and a big…

    Weekend Edition — the week in review. • Three Fed officials dissented in favor of a rate hike while the committee held at 3.5–3.75% — that level of internal disagreement signals tightening is closer than markets appear to have priced in. • US strikes on Iran were launched then paused, briefly pushing oil toward $100 a barrel; the Bank of Japan held at 1% while intervening in currency markets, raising carry-trade unwind risk. • A Coldcard firmware flaw drained ~$70M in bitcoin over the week, while a bipartisan Senate compromise on the Clarity Act removed the main political obstacle to US crypto market-structure legislation.

    Jul 31 — US-Iran strikes, Fed split, and AI earnings surge

    • The US struck dozens of Iranian targets after Tehran fired ballistic missiles at a US base in Jordan — a direct exchange of fire between the two countries that raises the risk of a wider Middle East conflict and a spike in oil… • The Fed held rates at 3.5–3.75% but drew three dissents in favor of a hike, while Q2 GDP printed at just 1.5% with inflation still elevated — a stagflationary bind that pushes rate cuts further out and leaves policymakers with… • Microsoft's Azure crossed $100B in annualized revenue for the first time and Samsung's chip operating profit ran more than 250 times higher year-on-year — both driven by AI demand, reinforcing the theme as durable rather than…
