Yesterday's Recap

US markets sold off sharply as geopolitical risks from the Iran war dominated sentiment, driving risk-off moves across equities. The S&P 500 closed at 6,506.48 after a 1.51% decline, led by tech and small-cap weakness, while the Nasdaq 100 fell 1.88% to 23,898.15 and the Russell 2000 dropped 2.26% to 2,438.45. Treasury yields showed divergence, with the 2-year rising 0.80% to 3.79% on inflation fears, but the 10-year eased 0.23% to 4.25% amid flight to quality.The USD rallied, gaining 1.07% against JPY to 159.61 and weakening EUR/USD by 0.77% to 1.15. Gold prices cratered 6.42% to 4,276.80, bucking safe-haven trends possibly due to liquidation, while WTI crude dipped 0.50% to 97.83 despite Middle East tensions. Bitcoin bucked the trend, rising 1.01% to 68,528.60.No major US data releases occurred, leaving markets to react purely to news flow on Iran's attacks and Fed's steady stance.

The Day Ahead

Today's Chicago Fed National Activity Index at 04:30 ET, with prior at 0.18, could signal broader economic momentum amid war uncertainties. Tuesday brings ADP Employment Change Weekly at 04:15 ET (prior 9,000) and S&P Global Flash PMIs at 05:45 ET, including Composite (prior 51.9), Manufacturing (prior 51.6), and Services (prior 51.7), offering early reads on Q1 growth. API Weekly Crude Oil Stocks at 12:30 ET (prior 6.6M) and a speech by Fed's Barr at 14:30 ET may influence energy markets and rate expectations.Wednesday features MBA 30-Year Mortgage Rate at 03:00 ET (prior 6.3%), Current Account Balance at 04:30 ET (prior -226.4B), and trade price data, alongside EIA oil inventories at 06:30 ET. These releases could sway Treasury yields and USD if they highlight inflation or demand shifts from global tensions. Fed's Miran speech at 12:10 ET on Wednesday adds to policy watch.

Other Economic Notes

US CPI YoY stands at 2.31%, reflecting moderated inflation pressures but persistent above-target levels that constrain Fed easing. Unemployment at 4.40% indicates a resilient labor market, supporting consumer spending despite geopolitical headwinds. Broader themes include potential supply chain disruptions from Iran conflict, which could elevate energy costs and challenge the "soft landing" narrative.

Global Macro News

Escalating US-Iran war has upended global markets, with Iran's Supreme Leader calling for unity amid attacks on US allies like Diego Garcia, heightening recession risks as noted in reports. GCC nations denounced Iran's aggression, potentially disrupting oil supplies and boosting WTI prices long-term despite yesterday's dip. European setbacks, such as a British startup shifting a 10B euro supercomputer project from France to the US, underscore transatlantic economic shifts favoring America.African nations like Kenya face debt crises from irrigation investments amid food security fears, indirectly pressuring global commodity flows. Nigeria's persistent high inflation in some states above 20% contrasts with national easing to 15.06%, signaling uneven global recovery. Recession risks are rising globally, per analyses, with US markets feeling the spillover through lower equity valuations and higher volatility.

Fed Watch

The Federal Reserve held interest rates steady at the recent FOMC meeting, with Chair Powell highlighting uncertainty from the Iran conflict in his remarks. Forward guidance maintains one rate cut in play for this year, emphasizing data-dependence amid inflation risks, as the fed funds rate remains at 3.64%. The committee noted potential economic fallout from geopolitical tensions, without altering the dot plot significantly, focusing on monitoring impacts on growth and prices.Quantitative tightening continues unabated, supporting higher yields at the short end. This stance implies markets should brace for prolonged higher rates if war escalates, potentially pressuring equities while bolstering the USD. Recent enforcement actions against bank employees signal regulatory vigilance, but core policy remains anchored on achieving 2% inflation sustainably.Overall, the Fed's communications suggest caution, reducing odds of aggressive easing and fostering Treasury curve steepening.
