US-Iran Ceasefire Sends Oil Plunging 16%, Triggers Best Day for Stocks in a Year
Markets staged a dramatic turnaround this week as the United States and Iran agreed to a two-week ceasefire, allowing safe passage through the Strait of Hormuz and easing fears of a prolonged energy supply disruption. West Texas Intermediate crude oil tumbled 16.4% to $94.41 per barrel, its steepest single-day decline since April 2020, after trading as high as $117 earlier in the week. The S&P 500 surged 2.51% to close at 6,782.81, and the Dow Jones Industrial Average gained 1,325 points (2.85%), its strongest session since the tariff rollback of April 2025. The Strait of Hormuz had seen sharply reduced traffic since the U.S. and Israel launched strikes on Iran in late February, causing what analysts called the largest disruption of crude supply flows in history. While the ceasefire brought immediate relief, crude remains well above its pre-war level of $67 per barrel, and analysts caution the geopolitical situation remains fragile. Source: CNBC, NPR

March CPI Cools to 2.1%, Markets Now Pricing June Fed Rate Cut at 85% Probability
The March Consumer Price Index report, released Wednesday, showed headline inflation fell to 2.1% year-over-year, its lowest reading in five years, with monthly prices rising just 0.1%. Core CPI moderated to 2.3% year-over-year as shelter and core services costs showed meaningful deceleration. The data triggered a sharp rally in growth stocks: Nvidia shares surged 4.2% to new all-time highs and Microsoft gained 2.8%. The 10-year Treasury yield sank below 3.8%, and traders on the CME FedWatch Tool now price an 85% probability of a 25-basis-point rate cut at the June Fed meeting. The Fed has held rates at 3.50%–3.75% since late 2025, having cut by a combined 1.75 percentage points over 2024 and 2025. With both inflation and geopolitical tensions easing simultaneously, investors are now debating not whether the Fed will cut, but how quickly normalization will proceed.

Trump Updates Section 232 Tariffs on Steel, Aluminum, and Copper as U.S. Effective Rate Hits 80-Year High
President Trump signed a proclamation on April 2 modifying existing Section 232 tariffs on steel, aluminum, and copper, with the changes taking effect April 6. The modifications are designed to ensure tariff rates fully reflect import values and to streamline derivative product classifications. The Commerce Department also opened an inclusions window through April 14 for automobile parts under the Section 232 auto tariff process. The broader tariff picture remains stark: the U.S. average effective tariff rate now stands at 11%, its highest level since 1943. Economists estimate that level equates to roughly $1,338 in lost annual purchasing power per household. General Motors has warned that full-year tariff costs could reach $4 billion in 2026.

U.S.-China Trade War Enters Diplomacy Phase as May Trump-Xi Summit Approaches
The United States and China are maintaining their bilateral tariff truce at 10%, agreed upon at the October 2025 Busan summit and extended through November 2026. The arrangement has stabilized trade flows after the extreme volatility of 2025, when tariffs briefly reached 145% on Chinese goods. New fault lines are emerging, however: U.S. Trade Representative Jamieson Greer announced Section 301 investigations in March into alleged excess manufacturing capacity in China, Mexico, and the EU, following the Supreme Court's invalidation of the IEEPA-based tariff authority. President Trump's upcoming visit to China in May will be his first in eight years and will be closely watched for signals on technology restrictions, intellectual property protections, and the longer-term trajectory of bilateral trade.

Meta Launches Muse Spark, Its First Closed AI Model, Marking a Break from Open-Source Roots
Meta unveiled Muse Spark on Wednesday, the first model from Meta Superintelligence Labs, the division led by Scale AI founder Alexandr Wang. The launch marks a sharp strategic departure from Meta's longstanding open-source AI commitment: Muse Spark is proprietary and closed, with access currently limited to the meta.ai portal and a private API for select partners. The model accepts voice, text, and image inputs and will be integrated across WhatsApp, Instagram, Facebook, and Messenger in coming weeks. On HealthBench Hard, a leading medical benchmark, Muse Spark scored 42.8%, outperforming all rival models including GPT-5.4, Gemini 3.1 Pro, and Claude Opus 4.6. Meta acknowledged remaining gaps in coding and long-horizon agentic tasks. The move signals Meta's intention to compete directly at the AI frontier rather than ceding that ground to closed-model rivals. Source: TechCrunch, CNBC

Anthropic Revenue Triples to $30B Run Rate as Company Seals Massive Compute Deal with Google and Broadcom
Anthropic announced this week that its annualized revenue run rate has surged to $30 billion, up from $9 billion at end-2025, driven by explosive enterprise demand for its Claude AI models. To meet that demand, the company signed an expanded compute agreement with Google and Broadcom, securing 3.5 gigawatts of TPU-based processing capacity coming online in 2027. Anthropic now counts more than 1,000 enterprise customers spending over $1 million annually. Mizuho analysts estimate Broadcom will receive $21 billion in AI-related revenue from the Anthropic deal in 2026, rising to $42 billion in 2027. The deal follows Anthropic's $30 billion Series G at a $380 billion valuation. The revenue growth highlights both the scale of enterprise AI adoption and the extraordinary capital intensity of operating at the frontier. Source: TechCrunch, Bloomberg
