Aug 17 – Aug 23

The 60-day U.S.–Iran memorandum expired without a permanent settlement, and Tehran warned it would shift to a fully offensive posture as disputes over the Strait of Hormuz remained unresolved. Reuters reported that Washington ruled out extending the temporary arrangement, while Al Jazeera and Gulf News described the return of sanctions pressure and the naval blockade that had been partially eased after June’s agreement.

The market transmission was immediate. Brent moved above $90 per barrel, reaching roughly $93.78 during the week, while WTI rose into the high-$80s as traders reassessed tanker traffic, Iranian exports, and the possibility that millions of barrels of Middle Eastern supply could remain stranded. Washington also prepared what Treasury Secretary Scott Bessent called the toughest sanctions in history, including action against Chinese independent refineries that have continued processing Iranian crude. The UAE’s decision to suspend trade and financial transactions with Iran further threatened Tehran’s commercial back door.

Lebanon’s renewed clashes added a second front to a framework that explicitly covered military operations across the region. That sets up a more persistent energy risk premium: even if physical disruptions remain limited, the threat of tighter sanctions and impaired Hormuz traffic can keep oil elevated, complicating the disinflation path and reinforcing pressure on long-duration assets.

Long-dated sovereign yields became the week’s dominant market variable. The U.S. 30-year Treasury yield briefly exceeded 5.28%, its highest level since 2007 according to Reuters and CNBC, while the 10-year traded near 4.70%–4.74%. The move was driven less by a fresh central-bank decision than by rising fiscal concerns, elevated term premia, and renewed oil-related inflation risk after the U.S.–Iran framework failed.

The pressure spread across developed markets. Germany’s 30-year Bund yield reached its highest level since 2011, German 10-year yields held around 3.25%, and 10-year gilts remained near 5%. The Treasury’s midweek increase in longer-dated buybacks offered only temporary relief; yields and intraday volatility returned by Friday. The episode underscored that official demand-management tools cannot easily offset a market reassessment of sovereign supply and long-run inflation compensation.

Equities absorbed the repricing unevenly. The S&P 500 fell 1.4% for the week, the Nasdaq lost 2.1%, and information technology dropped more than 3% as duration-sensitive growth stocks bore the adjustment. Japan’s Nikkei declined nearly 4%, while European shares held up somewhat better after softer PMIs moderated immediate ECB tightening fears. The coming week therefore begins with a two-track market: resilient activity supports earnings, but the long end—not the front end—sets the hurdle for valuations.

The U.S. July CPI report softened at the margin: headline inflation eased to 3.4% year over year from 3.5%, while core CPI reached 2.5%, its lowest level since just before the Middle East conflict. Deloitte and the reported BLS figures pointed to easing shelter and services pressure despite higher energy costs, prompting markets to reduce the perceived risk of near-term tightening and increase expectations for a September Federal Reserve cut.

That improvement did not erase the broader inflation problem. Citi put advanced-economy CPI at an average 2.9%, with U.S. core inflation around 2.6%, while S&P Global said global composite output had risen in each of the four months through July and forecast 2026 global growth of 2.4%. The combination of resilient demand and inflation settling around 2.5%–2.75% leaves policymakers with less room to respond aggressively to weaker pockets of activity.

Europe faces the same tension. The Bundesbank reported stronger euro-area momentum and German GDP growth of 0.2% in the second quarter, but July advanced-economy inflation remained 3.1% and German inflation rebounded to 2.8%. Japan’s 10-year yield reached a three-decade high as markets tested the BOJ’s tolerance for normalization. The implication is a divergence between softer near-term rate expectations and structurally restrictive financial conditions, especially at the long end.

The dollar fell even as U.S. yields rose, an unusual combination that framed the week’s cross-asset positioning. The dollar index declined roughly 0.9% toward 98.8, the euro rose about 1% to around $1.169, and the Swiss franc strengthened sharply against the dollar. Market coverage linked the move to concerns over U.S. debt, policy uncertainty, and the longer-term purchasing power implied by persistent fiscal deficits.

Gold benefited most directly from that unease. Spot prices reached roughly $4,604–$4,620 per ounce and gained about 5% for the week, helped by the softer dollar and a temporary decline in yields after the Treasury buyback announcement. Its advance alongside stressed bond markets suggested that investors were seeking protection from sovereign-duration risk, not merely hedging a conventional equity drawdown.

Bitcoin supplied the higher-beta version of the same scarcity narrative, though with a distinct policy catalyst. President Trump urged Congress to pass the crypto Clarity Act, sending Bitcoin sharply higher and lifting Ether more than 9% in one session. Bitcoin finished in the mid-$70,000s, at times above $77,000, while crypto-linked equities outperformed despite the broader decline in major stock indexes. The split matters for positioning: gold reflected distrust of fiscal and monetary anchors, while crypto added regulatory optimism and speculative momentum.
