Aug 3 – Aug 9

The week’s most important market thread was the widening gap between confidence in AI demand and tolerance for the spending required to capture it. TSMC reported second-quarter net profit of T$706.6 billion, up 77% year over year, raised its 2026 revenue-growth outlook to slightly above 40%, and lifted planned capital expenditure to $60 billion–$64 billion. Its additional $100 billion U.S. commitment, taking the Arizona investment to roughly $265 billion, underscored how deeply the semiconductor supply chain is committing to advanced-node and packaging capacity.

That confirmation powered a sharp rally in large-cap technology. Amazon gained about 15% on cloud and AI strength, while Microsoft and other AI-linked names helped carry the Nasdaq 1.60% higher for the week. The demand signal extended beyond chips: Amkor and Nvidia signed a $1.5 billion packaging agreement, and AMD said its Helios rack-scale platform had entered production. Yet the market reaction was no longer uniformly celebratory. SpaceX fell 14% after flagging massive AI spending, while Apple dropped 7.4% after earnings raised chip-related concerns. Investors are increasingly separating evidence of demand from evidence of profitable returns.

The same discipline is appearing in software. OpenAI’s reported 80% price cut for GPT-5.6 Luna, alongside lower-cost offerings from Anthropic and Google, shifted competition toward throughput, specialization, and unit economics. With hyperscaler AI capex estimated near $725 billion for 2026, the coming week will turn less on whether demand exists than on whether guidance can justify its escalating price.

The Federal Reserve’s decision to keep the federal funds target at 3.50%–3.75% was less important for its headline outcome than for the disagreement beneath it. The 9–3 vote included three officials favoring a hike, while rate-probability measures assigned roughly 54% odds to a hike at the next meeting. That is an unusually hawkish market posture for a central bank that has not moved, and it kept the question of “higher for longer” firmly alive.

The July jobs report then complicated that positioning. CNBC described an unexpected loss of jobs, reinforcing the view that the Fed would not need to raise rates immediately. But the broader backdrop still argues against an easy pivot: Q2 real GDP grew 1.5% annualized, consumer spending and business fixed investment remained supportive, and June PCE inflation was 3.7% year over year despite easing from May. Earlier labor readings showed cooling rather than collapse, including a 4.2% unemployment rate and payroll growth as low as 57,000 in one recent report.

Bonds responded as though inflation and fiscal-duration concerns had not been resolved. The 10-year yield was reported around 4.65%–4.69%, while the 30-year reached 5.00% in Bloomberg’s snapshot, with the long end under greater pressure than short maturities. Equities ultimately absorbed the tension because earnings were strong, but the setup for this week is less forgiving: further evidence of labor deterioration could pull yields lower, while sticky inflation would validate the market’s hawkish tail.

Middle East developments remained a direct market variable rather than a background geopolitical risk. President Trump’s decision to call off planned strikes against Iran helped crude retreat early in the week and provided an immediate lift to U.S. equities. The S&P 500 rose 1.48% on August 3 and another 1.79% the next day as investors priced lower near-term escalation risk. RBC’s weekly range of roughly $84–$90 a barrel captured the market’s underlying unease even after the initial relief.

The diplomacy around the Strait of Hormuz was fragile. Iranian officials said efforts to restore an agreement with Washington were advancing and that Tehran and Oman were nearing terms to manage the waterway. By midweek, however, negotiations remained vulnerable to disputes over fees, and a ship moving through the strait was hit. One weekly assessment described the U.S.-Iran ceasefire as effectively collapsed even as Trump said talks continued. A gradual reopening could leave the global oil market with a substantial surplus, but the immediate trading issue is access: a contested chokepoint can sustain volatility even when the eventual supply balance looks comfortable.

The risk is not confined to Hormuz. Houthi threats against Saudi-linked shipping and attacks in the Red Sea, including reported strikes on tankers, kept Bab-el-Mandeb exposed as a second pressure point. That sets up a market in which each diplomatic headline can move both crude and equities, while any renewed disruption would test the resilience implied by the week’s risk rally.

The Ukraine war escalated materially on the ground and widened economically. Russian air strikes on Kyiv and surrounding areas killed at least 17 people overnight, described as the third major attack on the capital in roughly a week. Kharkiv and Kherson also suffered casualties or infrastructure damage, including a total power outage in Kherson. Russia had separately launched drone and glide-bomb attacks that killed civilians, including children, underscoring the renewed pressure on urban and energy targets.

Ukraine responded by striking Russian energy infrastructure, including refineries in Yaroslavl and Bashkortostan, where large fires were reported. The exchange suggests that the conflict’s economic perimeter is expanding: energy assets are increasingly both military targets and instruments for imposing costs on the other side. NATO was reported to be seeking additional air defenses urgently as President Zelenskyy warned of rising Russian missile production.

Washington’s sanctions posture could broaden that pressure beyond Russia. The Senate passed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 by 86–11, authorizing steep tariffs on China, India, and other countries to reduce dependence on Russian oil and gas. If enacted, the measure would transform the sanctions campaign into a larger test of trade alignment, particularly for major buyers of Russian energy. The coming week therefore brings two linked risks: further attacks on energy infrastructure and an expanding policy front that could complicate global oil flows even without a new disruption at sea.
