<h1>Stock market today: Dow, S&amp;P 500, Nasdaq jump to start week, oil slides amid Trump's warning to allies on Iran</h1>
<p>US stocks climbed on Monday as Wall Street weighed the likely impact of surging oil prices on the Federal Reserve's interest rate path and looked for signs of easing in the Strait of Hormuz supply disruption.</p>
<p>The Dow Jones Industrial Average (<a href="https://finance.yahoo.com/quote/%5EDJI">^DJI</a>) put on roughly 0.8%, almost 400 points, on the heels of <a href="https://finance.yahoo.com/news/live/stock-market-today-dow-sp-500-nasdaq-slide-to-cap-3rd-week-of-losses-as-100-oil-sparks-inflation-fears-200021158.html">another shaky week for equities</a>. Meanwhile, the S&amp;P 500 (<a href="https://finance.yahoo.com/quote/%5EGSPC">^GSPC</a>) and the tech-heavy Nasdaq Composite (<a href="https://finance.yahoo.com/quote/%5EIXIC">^IXIC</a>) moved up about 1% and 1.2%, respectively.</p>
<p>Wall Street is keeping a <a href="https://finance.yahoo.com/news/the-straw-that-stirs-the-drink-wall-street-weighs-impact-of-surging-oil-prices-133021522.html">close watch on developments in the Strait of Hormuz </a>as the Middle East conflict enters its third week. Several <a href="https://www.bloomberg.com/news/articles/2026-03-14/two-lpg-ships-sail-through-hormuz-on-way-to-shortage-hit-india">tankers successfully transited</a> the waterway over the weekend, injecting some hope into markets that the key <a href="https://finance.yahoo.com/news/iran-upper-hand-hormuz-pressuring-082531728.html">conduit for crude supply might reopen</a>. At the same time, President <a href="https://finance.yahoo.com/news/trump-demands-help-other-countries-001639208.html">Trump put pressure on allies</a> to join the US in breaking Iran's blockade of Hormuz, warning NATO <a href="https://finance.yahoo.com/news/donald-trump-warns-nato-faces-230557213.html">faces a "very bad future"</a> if they don't help.</p>
<p>Futures for West Texas Intermediate (<a href="https://finance.yahoo.com/quote/CL=F">CL=F</a>) and Brent (<a href="https://finance.yahoo.com/quote/BZ=F">BZ=F</a>) both topped $100 a barrel in early trading on Monday before declining roughly 5% during a volatile session.</p>
<p>The impact of surging oil prices on inflation is in focus as Federal Reserve officials gather for their two-day policy meeting this week. Uncertainty around the fallout from the Iran war is seen as potentially <a href="https://finance.yahoo.com/news/oil-price-spike-likely-to-keep-rates-on-hold-but-deepen-divisions-among-fed-officials-this-week-090015969.html">deepening divisions with the central bank</a> over the path forward on interest rates, though officials are expected to <a href="https://finance.yahoo.com/news/a-critical-fed-meeting-100-oil-and-micron-earnings-what-to-watch-this-week-113002550.html">leave rates unchanged</a> on Wednesday.</p>

<li>Grace O'Donnell<h2>Dollar Tree says more high-income consumers are shopping at the discount chain</h2><p class="yf-1fy9kyt">Dollar Tree (</p><a href="https://finance.yahoo.com/quote/DLTR">DLTR</a>) stock rose 7% in midday trading on Monday after the discount store operator reported an earnings beat but more cautious guidance than the Street expected.<p class="yf-1fy9kyt">In the fourth quarter, Dollar Tree reported a profit of $2.56 per share, compared with Wall Street analyst estimates of $2.52 per share, according to S&amp;P Global Market Intelligence data. Revenue of $5.45 billion missed expectations of $5.46 billion, which the company attributed to store closures due to severe winter storms.</p><p class="yf-1fy9kyt">In a call with analysts, Dollar Tree CEO Michael Creedon said the retailer grew sales across all income levels, though high-income households were its fastest-growing customer cohort as these consumers trade down to less expensive products. Creedon said higher-income consumers drove the discretionary categories, while lower-income shoppers tended to stock up on essential goods.</p><p class="yf-1fy9kyt">For 2026, Dollar Tree expects adjusted earnings of $6.50 to $6.90, compared with the Street's $6.63 estimate.</p><p class="yf-1fy9kyt">Executives said that a boost from a more favorable tariff environment since the Supreme Court struck down President Trump's most expansive duties would likely be offset by shipping disruptions stemming from the outbreak of war in the Middle East.</p><p class="yf-1fy9kyt">The company's CFO, Stewart Glendinning, also noted that it takes about four months to begin seeing the benefits of lower tariffs, as goods purchased at December's tariff rates — before the Supreme Court decision — are still cycling through inventory.</p></li>

<li>Jared Blikre<h2>Why oil shocks turn markets into a game of whack-a-mole</h2><p class="yf-1fy9kyt">Oil’s latest surge has investors focused on the inflation story — but energy shocks rarely hit markets in just one place.</p><p class="yf-1fy9kyt">Instead, they behave more like a game of whack-a-mole. Try to pin the impact on inflation, and the pressure pops up somewhere else: bond yields, currencies, or eventually economic growth.</p><p class="yf-1fy9kyt">Earlier, my colleague Jake Conley flagged a Bank of America report that highlighted a version of this risk, noting that markets may be underpricing the potential growth hit from a prolonged Iran conflict. Stocks remain resilient — the S&amp;P 500 is less than 5% from its highs — even as oil climbs and rate expectations shift.</p><p class="yf-1fy9kyt">Meanwhile, the US dollar is quietly doing what it often does during energy shocks: rallying. That’s a reminder that global stress and higher oil prices tend to pull capital back toward the world’s reserve currency — a reality that keeps frustrating the dollar-doom narrative.</p><p class="yf-1fy9kyt">Oil shocks rarely break markets outright. They just shift the pressure elsewhere.</p></li>
<li>Jared Blikre<h2>Transports attempt a rebound from key support after a punishing month</h2><p class="yf-1fy9kyt">Transports are one of my primary</p><a href="https://en.wiktionary.org/wiki/canary_in_a_coal_mine">canaries</a>— and they are quietly jumping higher today.<p class="yf-1fy9kyt">The Dow Jones Transportation Average (</p><a href="https://finance.yahoo.com/quote/%5EDJT">^DJT</a>) is up over 1% — its best day since Feb. 26 — led by strength in United Airlines (<a href="https://finance.yahoo.com/quote/UAL">UAL</a>), XPO (<a href="https://finance.yahoo.com/quote/XPO">XPO</a>), Uber (<a href="https://finance.yahoo.com/quote/UBER">UBER</a>), and Delta Air Lines (<a href="https://finance.yahoo.com/quote/DAL">DAL</a>). The move isn’t huge, but it stands out given how rough the month has been.<p class="yf-1fy9kyt">Even with today’s bounce, transports are still down nearly 9% month to date.</p><p class="yf-1fy9kyt">Heavyweights like Union Pacific (</p><a href="https://finance.yahoo.com/quote/UNP">UNP</a>), CSX (<a href="https://finance.yahoo.com/quote/CSX">CSX</a>), Norfolk Southern (<a href="https://finance.yahoo.com/quote/NSC">NSC</a>), and FedEx (<a href="https://finance.yahoo.com/quote/FDX">FDX</a>) remain sharply lower, leaving the group on track for its worst month since December 2024 and set to snap a five-month win streak.<p class="yf-1fy9kyt">Technically, last week’s lows came right near the transports' 100-day moving average around 17,600. If that support gives way, this market canary may start singing again.</p></li>
