Dow surges 1000 points, S&P 500 hits 7100 as Iran opens waterway
US stock markets hit record highs Friday after Iran declared the Strait of Hormuz completely open for commercial traffic during a temporary ceasefire with Israel and Lebanon. The Dow Jones jumped roughly 1,000 points, the S&P 500 rose 1.2 percent to surpass 7,100 for the first time in history, and the Nasdaq climbed 1.5 percent. Oil prices fell sharply on supply relief, with Brent crude dropping 9 percent. The rally marks part of a two-week market surge during which all major indices recovered from losses suffered since the Iran war began in late February. Investors are betting on a quick diplomatic resolution, though uncertainty remains about the ceasefire's duration and whether broader peace talks will succeed before mid-April deadlines expire.

Limits of this briefing
The ceasefire is temporary and expires April 21, with peace negotiations still incomplete. Analysts caution that markets may be pricing in an optimistic outcome; one analyst noted uncertainty remains high and the market is betting heavily on Trump de-escalation based on past precedent. Strong technical factors like algorithmic buying and short-covering may be amplifying gains beyond fundamental justification.
