• Strait of Hormuz traffic under 10% despite ceasefire
• S&P 500 up 7.6% after March pullback, led by Magnificent 7
• February CPI and core PCED both rose 0.4% month‑over‑month
• Inflation stalled near 3% Y/Y, above the Fed’s 2% target

Pulse Analysis

The sudden dip in maritime traffic through the Strait of Hormuz highlights how geopolitical flashpoints can quickly translate into market signals. Even with a tentative ceasefire between the United States and Iran, Tehran’s directive for ships to remain in territorial waters has effectively throttled a critical oil conduit, reinforcing the perception of lingering supply‑side risk. Traders often price in such disruptions ahead of time, which explains why the S&P 500 rallied sharply after a steep March decline; investors are positioning for a return to normalcy as the conflict cools.

At the same time, the inflation narrative is diverging sharply between equities and fixed income. While headline CPI held at a modest 2.4% year‑over‑year in the pre‑war months, both headline and core producer‑price indexes ran hotter than forecasts, and February’s PCED data showed a 0.4% monthly rise. The persistence of a roughly 3% inflation rate—well above the Federal Reserve’s 2% goal—keeps bond investors wary, as higher price pressures could compel the Fed to maintain a tighter policy stance longer than equity markets anticipate. This split underscores the importance of monitoring both supply‑chain shocks and tariff‑induced price spikes.

Looking forward, the market’s resilience will hinge on two interrelated forces: the trajectory of the Middle‑East conflict and the economy’s productivity capacity to absorb cost increases. If the war remains contained and productivity gains offset the inflationary drag from tariffs and disrupted trade routes, equity performance may stay robust. Conversely, any resurgence of hostilities or a failure to boost output could cement higher inflation expectations, pressuring yields and potentially reshaping the risk‑return calculus for both stocks and bonds throughout the remainder of the year.
