- Iran announced the Hormuz Strait closure again on Saturday, halting the 20% of global oil and LNG shipments that flow through it.
- S&P 500 rose 4.5% last week, buoyed by optimism after the brief strait reopening.
- Nasdaq Composite jumped 6.8% and logged its 13th consecutive winning session on Friday, a streak not seen since 1992.
- Trump's tariff threats have been treated as a market lever, yet analysts warn his influence over the Iran conflict is limited.
- Matt Gertken warned investors that Iran’s higher pain threshold after being attacked will keep markets volatile beyond the ceasefire’s Tuesday expiry.
