Daily Market Briefing — 25 August 2026

Market Recap

US equities delivered a mixed session on Monday, with the S&P 500 slipping 0.28% to 7,652.86 and the Nasdaq 100 falling 0.97% to 29,023.18 as tech stocks faced pressure. The session was defined by two competing narratives: Treasury Secretary Bessent's sweeping Iran sanctions plan and the Treasury's bond buyback programme, which sent gold surging 1.17% to $4,695.10 and Bitcoin rallying 3.78% past the $80,000 mark. Oil tumbled on the sanctions news, with WTI down 2.69% to $84.72 and Brent off 2.77% to $91.78, as traders bet that tighter enforcement against Iran's enablers — particularly China — could eventually boost supply.

Key Movers & Themes

Crypto Breaks Out on ETF Inflows: Bitcoin surged past $80,000 for the first time since May, driven by renewed inflows into spot bitcoin ETFs and improving risk appetite. The rally extended the cryptocurrency's recent gains as the Treasury's buyback announcement weakened the dollar and fuelled demand for alternative assets. Gold's three-month high underscored the same dynamic — investors rotating out of dollars and into stores of value.

Trump Escalates Canada Trade War: President Trump announced the US will raise tariffs on Canadian cars, trucks and auto parts to 50% from 1 January 2027, sending the Canadian dollar sliding and putting Ford's $3 billion Canadian investment in the crosshairs. Canadian Prime Minister Mark Carney accused Trump of wanting to "destroy" Canada's auto industry and said he would only resume talks if the US comes with the "right attitude". The escalation comes as Canada, which sells 70% of its goods to the US, scrambles for leverage in a spiralling dispute.

Iran Sanctions Hit Oil Markets: The Trump administration unveiled what it called "economic D-Day" — a plan to isolate Iran's economy by threatening secondary sanctions on the Islamic Republic's enablers, with China explicitly not exempt. Iran said it was ready to counter what the US called the "greatest financial offensive ever", but oil markets took the news as bearish, betting that tighter enforcement could eventually increase global supply. The sanctions target a small group of governments that account for most of Iran's remaining foreign trade.

The Big Question

Can tech hold the line after Monday's sell-off? The Nasdaq 100's near-1% drop was led by semiconductor weakness, with Micron down 5.83% and AMD falling 3.49% despite broader market resilience. Bulls point to strong breadth in the Dow, plus Bitcoin's breakout signalling risk appetite remains intact. Bears counter that tech valuations are stretched and the sector is vulnerable to any further escalation in US-China tensions via the Iran sanctions route. Today's consumer confidence data could tip the balance.

Economic Calendar — What to Watch Today

• 08:00 GMT — Germany Ifo Business Climate (Aug): Forecast 87.2 vs 86.6 prior. The most important release today — a beat would support European equities and the euro, while a miss could weigh on UK-listed exporters to the continent.
• 14:00 GMT — US CB Consumer Confidence (Aug): Forecast 91.2 vs 90.8 prior. A key gauge of US spending power ahead of the holiday season. Any surprise here moves the dollar and US indices.
• 14:00 GMT — US New Home Sales (Jul): Forecast 0.62M vs 0.628M prior. Housing data remains critical for Fed watchers, though the Treasury buyback plan has already shifted the yield curve narrative.
• 13:00 GMT — US S&P/Case-Shiller Home Price YoY (Jun): Forecast 1.7% vs 1.6% prior. Another housing datapoint to watch for signs of cooling or resilience.
• 12:00 GMT & 20:00 GMT — Fed Barkin Speeches: Two appearances from the Richmond Fed President — any hawkish tilt could pressure equities, though the Treasury buyback story has muted Fed influence on long-end yields.

Technical Levels to Watch

The 480 level on MSFT is critical today — it's acting as both the classic S1 support and the Camarilla S4 breakdown trigger. Breadth across the Dow constituents shows 4 stocks in full bullish EMA alignment versus 6 in bearish, with 10 mixed — a cautious picture. MACD signals are evenly split with 10 bullish crossovers and 10 bearish across both indices.

Commodities & Currencies

The commodity complex split sharply on Monday: precious metals rallied on dollar weakness and Treasury buyback plans, while energy sold off on the Iran sanctions announcement. Gold's move to $4,695 marks its highest level in over three months, supported by a weaker dollar and safe-haven flows. Oil's 2.7% drop reflects expectations that tighter sanctions enforcement could eventually increase global supply, though the risk of supply disruptions remains. Sterling and the euro both gained over 0.6% against the dollar, while Bitcoin's 3.78% surge past $80,000 confirms the cryptocurrency rally is gathering pace on renewed ETF inflows.

Trading Outlook

Neutral with a bullish tilt into the US session. The catalyst that flips this: a miss on US consumer confidence at 14:00 GMT combined with any hawkish Fed rhetoric from Barkin would pressure risk assets and test the S&P 500's 7,638 support.
