I. Market Outlook

Core Events

After the opening round of US-Iran diplomatic dialogue, the US administration issued a 60-day waiver that lifts crude export sanctions against Iran. Senior US officials confirmed de-escalation in Lebanon, lifting broad market optimism over follow-up bilateral negotiations.

UK Prime Minister Starmer officially resigned, paving the way for an internal Labour power transition. Leadership favorite Andy Burnham will assume the premiership as soon as next month, marking seven prime ministerial changes within a 10-year window.

Deutsche Bank’s baseline outlook calls for two 25-bp interest rate hikes at the September and December FOMC meetings respectively.

Market Reaction

The Nasdaq fell 1.32%, the S&P 500 retreated 0.37%, while the Dow climbed 0.29%. July WTI crude futures closed 2.32% lower at $74.82 per barrel. August Brent crude settled 3.31% down at $77.90 per barrel, with an intraday trough more than 4% below the opening level.

The US Dollar Index edged up 0.16% to hit 101. Spot gold declined 1% to $4,181 per troy ounce.

Exclusive Insight

The 60-day crude export sanctions waiver represents a substantive policy concession from Washington, creating an unobstructed channel for Iranian crude to re-enter global supply chains. The 4% intraday drop in Brent fully prices in this incoming supply surge.

Nevertheless, the temporary 60-day validity imposes uncertainty over renewal terms, which will be tied to tangible progress in subsequent negotiations. This dynamic retains upside rebound potential for crude prices.

Starmer’s resignation will bring the UK its seventh prime minister in a decade. Recurring political instability has steadily weakened the long-term investment appeal of sterling and UK gilts among global fixed-income allocators.

II. Overnight Market Performance

Summary

The US’s temporary crude export sanctions relief for Iran triggered a deep selloff across oil benchmarks. The Nasdaq fell more than 1% amid broad losses among large-cap technology constituents.

— US Equities:

Dow Jones Industrial Average: +148.01 pts (+0.29%) to 51,712.71

S&P 500: -27.79 pts (-0.37%) to 7,472.79

Nasdaq Composite: -351.33 pts (-1.32%) to 26,166.60

💡 Mega-cap technology heavyweights weighed on the Nasdaq, pushing the index’s loss above 1%. The Dow staged a two-session recovery as institutional investors rotated capital out of overvalued tech names into undervalued value stocks. Lower crude prices, driven by US-Iran diplomatic progress, reduce energy input costs for manufacturers and consumers, offering support to cyclical consumer and industrial sectors.

— European Equities:

STOXX Europe 600: +0.6%

German DAX: +0.62%

UK FTSE 100: +0.72%

French CAC 40: -0.25%

💡 European benchmark indexes staged a broad recovery on improved regional energy cost outlooks amid falling oil prices. The FTSE 100 outperformed peers; markets have already partially priced in Starmer’s resignation, supporting a mild bounce in sterling.

— Fixed Income:

US 2-year Treasury yield: +4.89 bps to 4.228%, the highest print since February 2025

US 10-year benchmark Treasury yield: +5.78 bps to 4.509%

💡 The entire US Treasury yield curve shifted upward as market pricing for Fed monetary tightening strengthened. The front-end 2-year yield hit a four-month peak, with traders fully pricing in a September rate hike.

— Commodities:

July WTI crude futures: -2.32% close at $74.82/bbl

August Brent crude futures: -3.31% close at $77.90/bbl

COMEX June gold futures: -1% close at $4,181.9/troy oz

💡 Brent crude breached the key $78 support threshold, with the US 60-day Iranian crude export waiver serving as the dominant bearish catalyst. Markets are fully pricing a substantial supply boost as Iranian oil returns to global trade. Gold slipped to $4,181, pressured simultaneously by a stronger US dollar and rising Fed rate hike expectations.

— Foreign Exchange:

US Dollar Index: +0.16% to 101

EUR/USD: -0.36% to 1.1427

USD/JPY: +0.16% to 161.54

💡 The US Dollar Index reclaimed the psychological 100 level, supported by two core drivers: solid Fed tightening bets and broad safe-haven asset demand. USD/JPY hovers at 161.54, continuously testing the intervention threshold monitored by Japanese monetary authorities.

— Crypto Assets:

Bitcoin: +0.9% to above $64,000 per BTC

Ethereum: nearly +1% to $1,735.28 per ETH

💡 Bitcoin rebounded above $64,000 as marginal risk appetite improved, though persistent rate hike expectations remain a lasting downside cap for all risk-sensitive crypto assets.

III. Macro News

🕊️ The US issued a 60-day crude export sanctions waiver following the opening round of US-Iran talks, while tensions in Lebanon have cooled

Insight: The temporary sanctions relief constitutes a tangible US concession, removing major barriers restricting Iranian crude exports. The 60-day expiry means Washington adopts a conditional renewal framework; extensions will only be granted upon meaningful negotiation breakthroughs. Crude faces near-term downside pressure, yet the scope for sustained deep losses remains limited.

🇬🇧 UK Prime Minister Starmer formally resigns; leadership frontrunner Burnham poised to take office as early as next month

Insight: The UK will see its seventh prime minister within a decade. Cyclical political instability is gradually eroding sterling and UK sovereign bonds’ long-term investment attractiveness. If Burnham assumes office, he will face two core headwinds: stabilizing domestic political order and reviving sluggish economic growth.

🏛️ Deutsche Bank: Two 25-bp Fed hikes in September and December; BofA forecasts 75 bps total tightening in 2026

Insight: Wall Street’s broad consensus has fully shifted to a hawkish Fed tightening narrative. Projected cumulative hikes of 75–100 bps imply a terminal federal funds rate above 4.5%, which will exert heavy valuation pressure on US equities and weigh on the residential real estate sector.

🇨🇦 Canada May CPI rose to 3.2%, a 29-month high, exceeding the market consensus of 3%

Insight: Global inflationary pressures have not fully faded. As a net energy exporter, Canada should theoretically benefit from elevated crude prices via an improved trade balance, yet imported inflation is eroding household domestic purchasing power. The Bank of Canada may be forced to resume monetary tightening measures.

🛢️ Inventories within the US Strategic Petroleum Reserve (SPR) fell to 331.2 million barrels, the lowest level recorded since June 1983

Insight: SPR stockpiles have hit a multi-decade historic trough after multiple emergency release cycles. This creates structural long-term replenishment demand for federal reserves; crude prices below $85 per barrel will trigger official repurchase operations, forming a solid downside buffer for oil benchmarks.

IV. Corporate News

🚀 SpaceX issued its first tranche of investment-grade corporate bonds, raising $200 billion to fund large-scale AI infrastructure construction

Insight: This post-IPO debt offering reflects massive capital expenditure requirements for SpaceX’s AI hardware and space data center development. An investment-grade credit rating signals positive credit evaluation from global rating agencies, yet the $200 billion fundraising scale also means a rapid accumulation of long-term debt liabilities.

💾 Micron sealed a multi-year long-term memory supply framework with Anthropic

Insight: This represents another landmark transaction where leading AI developers lock stable semiconductor storage capacity. Micron CEO’s judgment that memory chips form an overlooked bottleneck for generative AI has been validated industry-wide. Multi-year supply agreements grant Micron steady pricing power and clear long-term revenue visibility.

🇯🇵 TOTO allocated JPY 800 billion to develop advanced semiconductor materials, targeting mass production of 1nm process chips

Insight: TOTO, widely known for sanitary ware products, serves as a typical example of Japan’s traditional manufacturers pivoting toward high-end semiconductor supply chains. The JPY 800 billion (approximately $7 billion) investment marks a strategic long-term layout rather than a symbolic minor investment.
