Market Summary - June 18, 2026
The Nasdaq 100 (US100) experienced a significant rally, increasing by 2.7% before the weekend, trading just below its all-time high of approximately 30,790. This surge was largely attributed to a recent peace agreement between the US and Iran, which alleviated geopolitical tensions and redirected capital flows back into riskier equities.

- Broadcom: +4.14%
- Nvidia: +1.94%
Despite a minor decline in Microsoft (-0.89%), the positive momentum in technology was supported by the Communications sector (+0.69%) and Consumer Discretionary (+0.55%), with Amazon contributing +1.97%. However, the Energy sector faced a decline of -2.30%, and Health Care fell by -0.78%.

Geopolitical Context
The easing of tensions between the US and Iran, following the signing of an interim peace agreement, played a crucial role in the market's performance. This agreement is expected to reopen the Strait of Hormuz for commercial shipping and roll back sanctions on Iranian crude oil, although complex issues regarding Iran's nuclear program remain unresolved for a 60-day negotiation period. The reduction in oil prices, with Brent crude dropping by 3% to around $78 a barrel, contributed to a relief rally across Wall Street as investors shifted from energy hedges back into equities.
Market Reactions
The Dollar Index (USDIDX) rose by 1% this week, reaching its highest level since May 2025, bolstered by a hawkish stance from the Federal Open Market Committee (FOMC). Meanwhile, US 10-year treasuries showed minimal volatility.
