Tame CPI and bullish WASDE lift equities as Hormuz supply shock deepens

Markets navigated a dense data day on August 12 with measured optimism, as a softer-than-feared CPI print anchored rate expectations and the S&P 500 added +0.26% to close at 7,748.50 — well above its 20-day moving average of 7,568 and 50-day of 7,510, with RSI at 63.8 signaling momentum without yet touching overbought territory. The Nasdaq outperformed, rising +0.54% to 26,588.49, clawing back above its 50-day SMA of 26,012. Gold extended its advance, gaining +0.59% to $4,408.90, though it remains below the 200-day SMA of $4,496 — a level that, if reclaimed, would reset the technical picture for the metal. The 10-year Treasury yield dipped modestly to 4.68%, down 4 basis points on the day, while the US dollar edged up +0.19% to 100.01, hovering just above its 20-day and 50-day moving averages near 100.

The July CPI release was the macro pivot point of the session. Headline inflation printed at +0.1% month-over-month and +3.4% year-over-year — down from 3.5% in June — largely thanks to a roughly 6.2% drop in gasoline prices during the measurement window. Core CPI rose 0.2% MoM and 2.5% YoY, matching consensus forecasts precisely. The benign data effectively shelved near-term rate-hike speculation, even as it fails to resolve the underlying tension: three Federal Reserve regional presidents, including Cleveland's Beth Hammack, dissented in favor of a hike at the July 28–29 FOMC meeting, the first three-way same-direction dissent since September 2016. Critically, inflation at 3.4% continues to outpace wage growth of 3.2%, preserving real household income pressure. The August 19 release of FOMC minutes will be the next stress test for rate expectations, with the hawkish dissent faction's reasoning likely to draw intense scrutiny.

The USDA's August WASDE delivered a bullish shock to corn markets. The agency slashed its corn yield forecast by 2.3 bushels per acre to 180.7 bpa — roughly 2 bpa below pre-report consensus of 182.4 bpa — and cut 2026/27 ending stocks to 1.653 billion bushels, well below both July's figure and Reuters trade expectations. While harvested acres were raised to 88.592 million and total production came in near-flat at 16.013 billion bushels, it was the demand-side tightening that drove corn futures sharply higher post-release. Soybean yield was trimmed to 52.7 bpa with carryout at 320 million bushels, a neutral read that left beans in a supportive but not explosive posture. Wheat global stocks were little changed. The WASDE adds a domestic supply-tightening narrative to an already inflation-sensitive environment.

The IEA's August Oil Market Report compounded geopolitical anxiety. The agency cut its 2026 global oil demand forecast by 510 kb/d versus its July edition and now projects full-year demand to fall 1.6 mb/d. More starkly, global supply is forecast to decline 4.3 mb/d in 2026 to 102 mb/d, with Americas growth of 1.4 mb/d only partially offsetting losses from the Middle East and Russia. The Strait of Hormuz crisis — triggered by US and Israeli military operations against Iran beginning February 28, 2026 — registered just 78 tanker transits in the week of August 3–9, down from 95 the prior week and a fraction of pre-crisis baseline volumes. Brent spiked above $100/barrel last month before retreating, and WTI on Wednesday barely moved, closing at $83.27, up just +0.08%, as the market balances acute supply disruption fears against demand destruction signals. The IEA warned that inventory buffers are depleting rapidly; no Strait reopening agreement is in place, and Iran has set conditions Washington has not accepted — removing any near-term diplomatic resolution from base-case pricing. WTI continues to trade well above its 50-day SMA of $79 and 200-day of $77, consistent with the structural supply premium embedded in current prices. The Treasury's $42 billion 10-year auction cleared at 4.683% — the highest auction yield since 2007 — with a tail of just 0.1 basis points, suggesting demand held but without enthusiasm. The prior month's reopening priced at 4.580%, a 10-basis-point climb in a single cycle, and the auction's timing — sandwiched between the CPI print and ongoing Hormuz disruption headlines — underscored fiscal premium concerns.

Looking ahead, the August 19 FOMC minutes carry outsized importance given the three-way hawkish dissent, and any language signaling a lower threshold for resuming hikes could abruptly reprice the short end of the curve. The Hormuz situation remains the single largest macro wildcard: a reopening agreement — which would require sustained diplomatic engagement and cannot be resolved by executive order alone given congressionally-mandated Iran sanctions under statutes like the Iran Sanctions Act and CAATSA — would trigger rapid repricing across energy, inflation expectations, and emerging market credit. Conversely, any escalation could push Brent back toward and above its recent $100 level. In agriculture, corn's tightening supply-demand balance warrants monitoring through weekly export inspections and any Midwest weather developments in the critical August pollination window. With the S&P 500 approaching overbought territory and gold's RSI at 68.0, position sizing in risk assets will be tested if the FOMC minutes deliver a more hawkish tone than current market pricing implies.
