Stock Market Recap: August 12, 2026 — Markets Mixed as CPI Cools, Energy Surges on Iran Tensions

Markets Navigate CPI Relief as Iran Tensions Keep Oil Elevated

Wall Street closed mixed on Wednesday, August 12, 2026, as investors cheered a better-than-expected July consumer price index (CPI) reading that eased fears of an imminent Federal Reserve rate hike — only to see those gains tempered by persistent oil price volatility tied to ongoing U.S.-Iran tensions over the Strait of Hormuz.

The July CPI report, released at 8:30 a.m. ET by the U.S. Bureau of Labor Statistics, showed annual inflation at 3.4%, below the 3.5% consensus estimate and down from 3.5% in June. The print was welcomed by bond and equity markets, which had been bracing for a hotter number following oil's sharp rally through late July. Treasury yields fell modestly on the data, and Federal Reserve rate hike odds for September retreated slightly — though they remained near 50/50 as of Wednesday's close.

Energy stocks surged as crude oil prices remained elevated near multi-month highs. The Energy Select Sector SPDR (XLE) was among Wednesday's top-performing sectors. Technology shares were mixed, with semiconductor stocks — particularly NVIDIA (NVDA) — facing continued selling pressure, while cloud monitoring and AI-adjacent names like Datadog (DDOG) staged a notable rebound.

Market Performance: August 12, 2026

The major U.S. indices ended Wednesday in mixed fashion, reflecting the tug-of-war between relief over cooling inflation and continued anxiety over energy prices and the Fed's next move.

Major Indices — Wednesday, August 12, 2026 Closing Prices

• S&P 500 (^GSPC): 7,728.20 (-0.32%, -24.91 points)

• Russell 2000 (^RUT): 3,027.12 (+0.32%, +9.72 points)

On Wednesday, equities opened with modest gains following the CPI print. The Dow traded as high as 54,175 in early trading before giving back some gains. Investor positioning remained cautious as traders weighed the CPI beat against still-elevated oil prices and uncertainty about the Federal Reserve's September meeting.

Top Stories of the Day

July CPI Comes In Cooler Than Expected at 3.4%

The Bureau of Labor Statistics reported Wednesday morning that the Consumer Price Index rose 3.4% year over year in July, below Wall Street's 3.5% consensus estimate and down from 3.5% in June. This marked a second consecutive monthly deceleration from the May peak of 4.2%, driven largely by a moderation in energy prices even as oil prices rebounded strongly in late July due to the ongoing Strait of Hormuz closure.

Core CPI — which excludes volatile food and energy prices — was widely expected to print around 0.2% month-over-month, rebounding from June's flat reading. The report was especially significant given the elevated energy backdrop. With Brent crude trading near $90 last week, many economists had feared a hotter print that would solidify the case for a September rate hike. Instead, the softer headline figure provided short-term relief to bond and equity markets.

Following the release, traders trimmed bets on a September rate hike from the Federal Reserve. According to CME Group's FedWatch Tool, markets were pricing approximately a 50/50 chance of a rate increase at the September 15-16 FOMC meeting — down from higher odds earlier in the week. Fed Chair Kevin Warsh, who has been described as willing to tolerate tighter policy to combat inflation, has not commented publicly on the CPI data.

Iran Tensions Keep Oil Elevated, Inflation Uncertainty Lingers

Oil prices remained a critical wildcard for inflation and monetary policy. West Texas Intermediate crude oil was trading near $83/barrel on Wednesday, while Brent crude hovered around $87-88/barrel after a four-session rally of more than 12% from its recent low. The Strait of Hormuz remains closed following the U.S. and Israel's military strikes against Iran in late February, and recent diplomatic efforts have stalled.

President Trump complicated negotiations further earlier this week by demanding that Iran pay compensation to families of people killed in the conflict — a demand Tehran has rejected. Analysts note that if oil sustains elevated levels, the CPI's cooling trend could reverse in August, keeping the Fed's September decision in play.

NVIDIA Partners with Financial Giants on $500 Billion AI Financing Initiative

NVIDIA Corporation (NVDA) announced a partnership with six major financial institutions, including BlackRock and Goldman Sachs, on a potential $500 billion financing initiative to support artificial intelligence infrastructure buildout. The news highlighted the scale of capital flowing into AI infrastructure, even as NVDA shares faced selling pressure of approximately 2.86%, closing around $217.55. Semiconductor stocks broadly continued their underperformance relative to the rest of the market, with the Philadelphia Semiconductor Index (SOX) remaining under pressure from rate hike fears and valuations.

Intel Upsizes Share Offering to $20 Billion

Intel Corporation (INTC) moved into the spotlight after increasing the size of its planned new share offering by $5 billion to $20 billion total. The move is seen as part of Intel's effort to fund its ambitious manufacturing recovery and foundry expansion. President Trump met with Intel CEO Lip-Bu Tan, calling the meeting 'very interesting' and praising Tan — a notable reversal from Trump's earlier criticism of the executive over his ties to Chinese firms. Intel shares traded near $97, under pressure from the dilutive share offering.

Biggest Movers

Datadog (DDOG) +11.48% — Recovering From Post-Earnings Selloff

Datadog Inc. (NASDAQ: DDOG) surged approximately 11.48% on Wednesday, trading in a range of $233-$248 versus a previous close of $229. The move represented a significant recovery from the stock's sharp -17% selloff on August 6, which had followed earnings guidance that disappointed on near-term sequential growth. This week, Macquarie raised its price target on DDOG to $260 (from $230), reiterating an Outperform rating citing the company's strong revenue beat and long-term observability market leadership. The cooling CPI print also helped growth and technology stocks broadly, as lower inflation expectations support higher equity valuations.

Energy Stocks Surge on Oil Rally — APA, MPC, FANG Lead

Energy stocks were among the market's biggest winners Wednesday. APA Corporation (APA) gained approximately 9%, Marathon Petroleum (MPC) rose over 7%, and Diamondback Energy (FANG) climbed nearly 6%. The Energy Select Sector SPDR (XLE) rose 4.6% on Monday and continued to outperform broadly this week. Oil companies benefit directly from elevated crude prices caused by the Strait of Hormuz closure, which has restricted Middle Eastern oil supply.

SpaceX (SPCX) +4.23% to $138.74

Space Exploration Technologies Corp. (NASDAQ: SPCX) continued its post-IPO momentum, gaining approximately 4.23% to close near $138.74 with exceptionally high volume of around 170 million shares. The company has been one of the most actively traded stocks in recent weeks following its landmark public listing. Vietnam's VinSpace also signed a deal with SpaceX to launch its first satellites in 2027, adding to the company's growing international commercial business. SpaceX recently reported its first-ever public quarterly earnings, showing strong Starlink subscriber growth and AI data center revenue diversification.

NVIDIA (NVDA) -2.86% — Semiconductor Pressure Continues

NVIDIA Corporation (NASDAQ: NVDA) fell approximately 2.86% to around $217.55 despite the $500 billion AI financing news. The stock has faced headwinds from rate hike fears, as higher Treasury yields compress valuations for high-multiple technology names. Micron Technology (MU) also declined about 1.89%. Analysts at UBS called Micron 'poised for a structural reset' in earnings power as high-bandwidth memory demand accelerates, with Macquarie's BofA analysts noting NVIDIA's next earnings could kick off a multi-quarter upgrade cycle.

Archer Aviation (ACHR) +11.99% — eVTOL Momentum

Archer Aviation Inc. (NYSE: ACHR) surged approximately 11.99% to close near $6.26. The electric vertical takeoff and landing (eVTOL) aircraft company has attracted investor interest alongside the broader aerospace and defense theme, benefiting from momentum in urban air mobility and recent favorable regulatory commentary.

Economic Data: July Consumer Price Index

The headline economic event of the week arrived Wednesday morning when the BLS released the July 2026 Consumer Price Index:

• Headline CPI (YoY): 3.4% — below the 3.5% forecast and down from 3.5% in June
• Previous month (June 2026): 3.5% YoY (-0.4% MoM, largest monthly decline since April 2020)
• Energy prices: Still a key upside factor; July energy costs had been elevated due to the Strait of Hormuz closure, though the June ceasefire provided some relief before tensions reignited
• Shelter: Running around 3.3% YoY — a sticky component watched closely by the Fed

The July CPI was particularly closely watched because market participants were trying to determine whether the Federal Reserve would raise interest rates at its September 15-16 meeting — the first potential hike in more than three years. Fed Chair Kevin Warsh signaled at the July 28-29 FOMC meeting press conference that he could tolerate a higher inflation environment, which investors interpreted as potentially hawkish. Bond investors had been pricing long-term inflation concerns into Treasury yields, pushing the 30-year Treasury bond yield near 20-year highs.

The softer-than-expected July CPI provides some breathing room for the Fed. However, with oil prices still elevated and the Strait of Hormuz remaining closed, the August CPI (due September 11) could easily reverse course. Investors will also watch Thursday's Producer Price Index (PPI) for further clues on the inflation pipeline.

Tomorrow's Market Calendar: Thursday, August 13, 2026

Economic Releases

• Producer Price Index (PPI) for July — The second major inflation reading of the week. After the cooler CPI, markets will watch PPI for consistency. A hotter PPI could reignite rate hike fears.
• OPEC Monthly Report — Expected Thursday; the report will include updated demand forecasts and commentary on production levels amid the Strait of Hormuz situation.

Earnings Reports

• Cisco Systems (CSCO) — Major networking equipment maker reports Q4 fiscal year 2026. Analysts will focus on AI networking infrastructure demand and enterprise IT spending trends.
• Applied Materials (AMAT) — Semiconductor equipment giant. Results will be scrutinized for guidance on future chip manufacturing capital expenditures.
• Lumentum (LITE) — Optical components maker that has been in focus given its AI data center transceiver exposure.

Federal Reserve

• No scheduled Fed speeches. FOMC Minutes from the July 28-29 meeting will be released on August 19. Investors will be watching for any commentary from Fed officials on the CPI data and September rate hike probability.

Conclusion: Inflation Cools, But the Fed Fight Isn't Over

Wednesday's cooler-than-expected CPI print was precisely the kind of data investors had been hoping for. At 3.4% year-over-year, July inflation came in below forecasts and continued a deceleration from the May 2026 peak of 4.2% — providing at least a temporary reprieve from the narrative that the Federal Reserve would need to raise rates in September for the first time in over three years.

However, the relief may be short-lived. Oil prices remain near multi-month highs as the Strait of Hormuz stays closed, and any further escalation in the Middle East could quickly reverse the inflation trend. The 10-year Treasury yield, while down modestly, remains well above pre-conflict levels near 3.97% and is still hovering around 4.69%. The Fed's September meeting remains a genuine coin flip, and Thursday's PPI report and future CPI readings will be critical.

For investors, the key themes to watch going into the second half of August include: the trajectory of Brent crude and U.S.-Iran diplomatic negotiations; the Fed's response to inflation data; FOMC Minutes (August 19); and a second wave of S&P 500 earnings from retailers and industrials. The market's August 'crash-up' — as some analysts have called it — now faces a genuine test as energy-driven inflation lingers.
