Inflation drivers push Nasdaq down 2% and lift oil 8% on Monday

The S&P 500 slipped under 1% but the Nasdaq 100 dropped almost 2% on Monday as three concrete inflation‑related events— a 20% Hormuz shipping fee, a Fed governor’s AI‑inflation warning, and a surge in tech‑bond issuance—spilled over into equities, oil and the dollar [1].

Hormuz fee spikes oil, drags growth stocks

President Trump’s announcement of a 20% fee on cargo through the Strait of Hormuz—where 20% of global oil passes—acted as a direct tax on a fifth of world oil supplies. Crude prices responded by climbing more than 8% on the news, a move that fed higher input costs and pressured high‑growth, high‑PE stocks, explaining why the Nasdaq 100 fell nearly 2% while the broader S&P 500 stayed under 1% [1].

Fed AI warning and bond supply tighten financing conditions

Fed Governor Christopher Waller told investors that inflation now stems from “artificial intelligence” spending, signaling that price pressures could persist beyond traditional energy and tariff drivers. Simultaneously, Wall Street Journal reporting of an unexpected surge in tech‑sector bond issuance to fund AI capex lifted yields and depressed bond prices. The combination of a Fed‑level inflation narrative and rising yields hit growth names hardest, sending the IBD 50 ETF down 2.5% and leaving only six of its 50 components in positive territory [1].

Dollar gains on safe‑haven demand, GBP stalls

Higher oil prices and the inflation narrative bolstered the U.S. dollar as investors sought safety amid Middle‑East tensions. The GBP/USD pair slipped to around 1.3390 in early European trading, reflecting the dollar’s strength against a subdued pound [2].

What to watch

• U.S. CPI release (June headline expected to fall 0.1% MoM, core up 0.3%) on Tuesday, which could confirm or refute the inflation narrative [2].
• Fed testimony by Chair Kevin Warsh before Congress on Tuesday, a potential catalyst for rate‑policy expectations [2].
• Oil price reaction to any further developments on the Hormuz fee or Middle‑East escalations, as a sustained rise could deepen growth‑stock pressure.

The market’s modest index declines mask a broader weakness in growth stocks and a shift toward inflation‑driven risk premia. Whether Monday’s moves signal a short‑term scare or the start of a more persistent inflation‑driven market environment will hinge on the upcoming CPI data and Fed commentary.
