📊 Today's Market Drivers
-
U.S.-Iran Ceasefire Extension & Tanker Seizure: President Trump declared on April 22 that the U.S.-Iran ceasefire would be extended indefinitely, triggering broad risk-asset buying globally. However, the same day brought reports of a U.S. military tanker seizure, sparking a sharp sentiment reversal on April 23. With peace talks now on hold, whether the truce actually holds has become the market's biggest wild card.
-
Tesla Earnings Shock: Tesla's post-market earnings on April 22 missed expectations, prompting S&P 500 futures to reverse course right after hitting new highs. The miss underscored earnings season volatility and triggered caution heading into April 23's open.
-
Fed Rate Path Uncertainty: Concerns over oil-driven inflation have dramatically cut investor expectations for Fed rate cuts this year to below 10bp (one cut or less). Market logic that strong corporate profits can sustain equities even in a high-oil, high-rate environment has been the cornerstone of the recent rally—but earnings season is now the ultimate test of that thesis.
