Daily Market Briefing — 18 September 2026

Market Recap

US markets clawed back ground on Thursday following the Fed's rate hike, with the S&P 500 closing up 1.14% at 7,637.76 and the Nasdaq 100 surging 1.73% to 29,446.98. The Dow Jones added a more modest 0.61% to finish at 51,778.04. The post-Fed bounce reflected easing fears over the pace of monetary tightening, though the rally lacked conviction in cyclical sectors. The divergence between the Fed's hawkish stance and the Bank of England's decision to hold rates steady is creating cross-currents in currency and bond markets.

Key Movers & Themes

Semiconductor Resurgence: Chip stocks extended their comeback on Thursday, with investor fears about AI spending slowdowns and interest rate impacts subsiding. Workday jumped 6.14% to 199.30, Micron Technology climbed 5.50% to 977.50, and Marvell Technology gained 4.81% to 240.80. AMD led the Dow constituents with a 6.36% surge to 545.09, while Nvidia added 2.54% to 219.34. The sector's strength suggests traders are betting the AI infrastructure build-out remains intact despite tighter monetary policy.

Oil Retreats on Saudi Supply Hopes: WTI crude fell 1.40% to $101.00 and Brent dropped 1.28% to $103.48 as Saudi Arabia pushed to export more oil through the Strait of Hormuz following the shutdown of its East-West pipeline. The move helped ease supply disruption fears despite fresh Houthi strikes in the region. Energy stocks couldn't find direction amid the conflicting signals — lower prices versus ongoing geopolitical risk.

Central Bank Divergence Deepens: The Bank of Japan raised interest rates to a 31-year high in a split 7-2 decision, flagging concerns over inflation driven by high energy prices. Meanwhile, the Bank of England held rates steady for the sixth consecutive meeting despite UK inflation rising to 3.1%, signalling it would only hike if energy prices remain elevated. The divergence is creating volatility in currency markets, with GBP/USD falling 1.21% to 1.3362 and USD/JPY rising 0.76% to 157.19.

The Big Question

Will Trump back down on Iran — or has the playbook changed? For six months, investors followed a simple rule: when Trump threatens Iran, buy the dip, because he always backs down. But in September, that strategy stopped working. A UN mission found evidence of potential US war crimes following missile strikes on Iranian targets, including a primary school attack that killed over 150 people. Markets are now questioning whether the so-called 'TACO trade' (Trump Always Caves On Iran) still holds. If it doesn't, oil volatility could spike sharply higher, dragging equity markets down with it.

Economic Calendar — What to Watch Today

• 06:00 GMT — UK Retail Sales MoM (Aug): Actual 0.5% vs forecast -0.2%, previous -0.5%. A strong beat that suggests UK consumers are more resilient than expected despite cost-of-living pressures. Watch for GBP strength if this feeds into BoE rate expectations.
• 06:00 GMT — Germany PPI YoY (Aug): Forecast 4.1% vs previous 3.0%. Rising producer prices in Europe's largest economy could add pressure on the ECB to maintain its hawkish stance.
• 10:30 GMT — ECB President Lagarde Speech: Any hints on the path of eurozone rates will move EUR pairs and European equity futures.
• 13:15 GMT — US Industrial Production MoM (Aug): Forecast 0.3% vs previous 0.2%. A key gauge of manufacturing strength as the Fed tightens policy.
• 13:30 GMT — Fed Bowman Speech: Watch for commentary on the pace of future rate hikes following Wednesday's decision.

Technical Levels to Watch

Meta is overbought at RSI 74.0, while Booking.com sits oversold at 29.1, suggesting potential mean reversion plays. MACD signals are split evenly across the scanner data, with 15 stocks showing bullish crossovers and 18 bearish — neutral territory that matches the cautious post-Fed mood.

Commodities & Currencies

Silver outperformed with a 2.25% gain to $66.94, riding the coattails of gold's modest 0.25% rise as safe-haven demand persists amid geopolitical uncertainty. The dollar strengthened against sterling and the euro following the Fed hike, with cable falling over 1.2% as the BoE's dovish hold contrasted sharply with US tightening. Bitcoin added 1.68% to $77,426.77, continuing its recovery from last week's lows as risk appetite improved post-Fed.

Trading Outlook

ECB President Lagarde's speech at 10:30 GMT is the catalyst that could flip sentiment if she signals eurozone rate cuts are off the table. Manage risk carefully into the close — geopolitical headlines remain the wildcard that could derail this fragile recovery.
