Today's Focus
Topics
AI Supply Chain Daily Focus — 31 July
Microsoft's 43% cloud growth and Amazon's 37% AWS acceleration reset the AI-capex debate in one session — chips ripped higher (Lam +20%, AMD/Intel +13%, CRWV +24%) and the market rewarded rather than punished record capex. The offsetting story: Apple named memory pricing a "hundred year flood" and guided September below consensus on supply constraints.
The Fed Holds: A Hawkish Pause That Outsources Tightening to the Market
The July FOMC held the range at 3.50%–3.75% as expected, but three dissents wanted 25bp now. The bigger shift is a quieter forward-guidance stance that lets market rates do the tightening — at the cost of policy clarity.
The AI Capex Supercycle: Where the Money Is Actually Going
Hyperscaler capex guidance keeps beating estimates, but the mix has shifted hard toward power, land and interconnect. A look at which parts of the chain are absorbing the incremental dollar.
The Memory Supercycle: How HBM Reallocation Is Squeezing Conventional DRAM
HBM's share of DRAM wafer output has roughly doubled in eighteen months. That reallocation, not new demand alone, is what's driving conventional DRAM pricing power.
Neocloud IPO Watch: Reading Through the Unit Economics
A wave of GPU-rental neoclouds is heading toward public markets. The pitch is straightforward; the unit economics — utilisation, depreciation schedules, contract duration — are where the real debate is.

Macro Research
2026-07-30Macro indicators tracked for their read-through to AI-linked equities, not a general economic dashboard.
Moderate Expansion · Sticky Inflation · Cautious Easing Bias
The US economy is still expanding at a moderate pace — real GDP growth has held up even as the labour market cools gradually rather than cracking. Inflation has eased from its recent highs but remains above target, which is why the Fed held rates in July despite three dissents wanting an immediate hike. The practical read for AI-linked equities: financial conditions are being set more by long-end Treasury yields than by the policy rate itself, which raises the discount-rate sensitivity of the most capex-heavy, longest-duration names in the chain.
Growth
The pace of economic expansion, which sets the ceiling for corporate earnings and capex capacity.
Growth is moderate but not stalling — the more AI-specific question is whether hyperscaler capex keeps growing faster than GDP, which it currently is by a wide margin.
▲ Real GDP US
2.4 % YoY (+2.4 YoY)
▲ ISM Manufacturing PMI US
51.8 index (+0.6 MoM · +2.1 YoY)
→ Consumer Confidence US
104.2 index (-1.4 MoM · +3.8 YoY)
▲ Hyperscaler Capex Growth US
38.5 % YoY (+38.5 YoY)
Inflation
Price growth across goods and services, the primary input to Fed policy decisions.
Memory and component cost inflation from AI-driven demand is a distinct, narrower story from headline CPI — watch it separately rather than assuming they move together.
▼ Headline CPI US
3.5 % YoY (-0.4 MoM · +3.5 YoY)
→ Core PCE US
3.4 % YoY (+0.3 MoM · +3.4 YoY)
▲ DRAM Contract Price Global
18 % QoQ
Labour Market
Employment and wage trends, which shape both consumer spending and the Fed's dual mandate calculus.
A cooling labour market with low layoffs is the most Fed-friendly outcome for a soft landing — but automation's employment effects are not yet visible in aggregate data at this point in the cycle.

Rates & Liquidity
The policy rate, yield curve and financial-conditions backdrop that set the discount rate for long-duration growth assets.
The single most important input to valuation multiples on capex-heavy, long-duration AI infrastructure names — more so than any single earnings print.
