War, Tariffs, and Tech: The Forces Moving Markets Now

👋 Welcome Back Investors! (February 23 to 27, 2026)

The final week of February brought a sharp mix of geopolitical tension and market moving earnings. Escalating conflict involving Iran, pushed oil prices higher and renewed inflation concerns, keeping global markets on edge. At the same time, Nvidia delivered another strong earnings beat, highlighting continued strength in AI demand. Meanwhile, a new U.S. tariff proposal added fresh trade uncertainty, pressuring equities and complicating the outlook. All in all, it was a volatile week that showed how quickly geopolitics, policy shifts, and corporate results can move markets.

📊 Nvidia Earnings: AI Momentum Powers Strong Forecast

Markets turned their attention to Nvidia this week as the chipmaker delivered another upbeat outlook, forecasting first quarter sales above Wall Street estimates. The company projected revenue that signals sustained strength in AI-related demand, reinforcing its dominant position in data center and advanced chip markets. The guidance suggests that enterprise and cloud spending on artificial intelligence infrastructure remains resilient, even amid broader macro uncertainty.

Investors are closely watching whether Nvidia’s growth trajectory can continue at this pace. While the strong forecast supports confidence in the AI trade, elevated valuations leave little room for disappointment. Any slowdown in demand or margin pressure could quickly shift sentiment in the tech sector. For now, however, Nvidia’s outlook underscores that AI investment remains one of the most powerful forces driving equity markets in 2026.

📦 Tariff Update: Trump’s Global Levy Enters at 10% Amid Legal Turmoil

Markets are navigating renewed trade uncertainty after President Trump’s new global tariff officially came into effect at 10%, lower than the previously signaled 15% rate. The move follows a Supreme Court ruling that blocked the administration’s broader tariff authority under emergency powers, forcing a temporary shift to Section 122 of the 1974 Trade Act. While the White House has indicated it may raise the rate to 15%, no formal directive has yet been issued, adding another layer of unpredictability for businesses and investors.

The policy reversal has reignited concerns about retaliation from major trading partners and the potential escalation of a wider trade conflict. Companies from logistics giant FedEx to smaller exporters are already seeking refunds on previously imposed tariffs, while global partners including the EU and India reassess trade agreements. For markets, the key issue isn’t just the 10% rate, it’s the uncertainty. With legal battles looming and policy direction shifting quickly, investors are once again weighing the risk that trade tensions could disrupt global growth and corporate margins in the months ahead.

🛢 Oil Shock Risk: Middle East Conflict Threatens Global Supply

Oil markets are bracing for a sharp surge after escalating U.S. and Israeli strikes on Iran, followed by swift retaliation from Tehran. Brent crude had already been climbing amid military buildup in the region, settling near $73 a barrel before over-the-counter trading reportedly spiked as much as $10 higher. At the center of investor concern is the Strait of Hormuz, the critical waterway through which roughly 20% of global oil supply, more than 20 million barrels per day, flows. With tankers anchoring and insurance costs rising, markets are now focused less on spare capacity and more on whether physical barrels can move.

While OPEC+ has announced a modest output increase, analysts suggest it may not be enough to calm medium-term volatility. Beyond shipping disruptions, investors are increasingly worried about the risk of direct attacks on oil infrastructure across the region, a scenario that could send prices sharply higher. For markets, the key question isn’t just how high oil could spike, but how long instability might last, and what that means for inflation, global growth, and central bank policy.

🌍 Global Markets Brace as Iran Conflict Ripples Through the U.S. Economy

Escalating conflict with Iran is quickly shifting from a regional military story to a global economic risk. With nearly 20% of the world’s oil flowing through the Strait of Hormuz, any prolonged disruption threatens to push crude prices sharply higher. Brent has already surged, and traders are increasingly pricing in the risk of sustained supply interruptions rather than a brief geopolitical flare up. For global markets, and especially the United States, the concern isn’t just oil, but the inflationary shock that could follow.

Higher energy prices would complicate the Federal Reserve’s path toward rate cuts, potentially keeping yields elevated and strengthening the U.S. dollar. That dynamic pressures equities, particularly rate sensitive growth stocks, while boosting safe haven demand for gold and defensive assets. Meanwhile, global shipping disruptions and rising insurance costs could feed into broader supply chain stress, adding another layer to inflation concerns. Investors are now watching two key variables: how long instability in the Strait of Hormuz lasts, and whether infrastructure, not just shipping routes, becomes a target. The outcome could determine whether this remains a temporary volatility spike or evolves into a broader macro shock affecting global growth, trade flows, and central bank policy in 2026.

👀 Stocks to Watch: What This Week’s Moves Reveal

Markets navigated a volatile mix of rising oil prices, renewed trade uncertainty, and shifting rate expectations this week. While Nvidia and tariff headlines grabbed attention, several other names quietly reflected where capital is rotating beneath the surface:

• Chevron (CVX | 1.00%) — Gained as crude prices surged on Middle East supply fears. The move highlights how integrated energy majors benefit not just from higher spot prices, but from improved cash flow expectations when geopolitical risk lifts the entire energy complex.

• Raytheon Technologies (RTX | 0.35%) — Advanced as defense spending themes reemerged amid global tension. Aerospace and defense names continue to attract capital as nations plan higher budgets and military modernization.

• United Parcel Service (UPS | 0.82%) — Logistics firms are closely tied to global trade flows. With tariff policy uncertainty resurfacing, transportation names serve as a real-time barometer of cross-border economic confidence.

• Delta Air Lines (DAL | 1.76%) — Pressured as rising oil prices lifted jet fuel cost concerns. Airline margins remain highly sensitive to energy volatility, particularly when crude spikes quickly.

🛎️That’s a Wrap!

Markets ended the week balancing geopolitical tension and corporate strength. Escalating conflict involving Iran pushed oil prices higher, reviving inflation concerns, while Nvidia’s earnings reinforced the AI growth story. At the same time, renewed tariff proposals added fresh trade uncertainty. All in, it was a reminder that geopolitics, policy shifts, and earnings momentum can quickly reshape market sentiment.

Until then, stay focused and stay curious. Catch you next week 👋
