Traditional Markets Weekly — September 18, 2026

Note: this material is an analysis methodology. It does not constitute a recommendation to buy, sell, or allocate.

1. Executive Summary

The Fed raised rates 25 bp to 3.75-4.00% on 09/16, its first hike since 2023, and the dollar and long yields responded: DXY rose 1.1% on the week to about 100.2 and the 10-year yield crossed 5%, the highest since 2007. Even so, gold snapped a three-week losing streak with a small gain (+0.4%) as falling oil eased inflation fears, and the S&P 500 finished essentially flat (-0.1%) while the Dow lost more than 1.5%. Oil stays the swing factor: WTI holds near $100 (up more than 18% on the month) on Houthi strikes on Saudi facilities, with Saudi rerouting through Hormuz easing fears late in the week. The VIX at 14.8 is calm, even though CNN's Fear & Greed reads 29 (Fear) — a divergence worth watching.

3. Key Events This Week

1. The Fed hikes for the first time since 2023. The FOMC raised the target range 25 bp to 3.75-4.00% on 09/16, with Kevin Warsh chairing the press conference; the dot plot median for end-2026 rose to about 4.1% from 3.8% in June and 2027 to 4.1% from 3.6% (Babypips, Bloomberg, 09/17-18). The robust reading is at least one more hike this year; the exact participant count conflicts across sources.
2. August CPI ran hot on energy. Headline +0.4% m/m and 3.4% y/y, in line; energy +2.1% and gasoline +3.9% m/m, core +0.3% m/m, slightly above expectations. Futures priced about 89% odds of a September hike after the print (CNBC, 09/11).
3. The 10-year yield crosses 5%. It climbed above 5% this week for the first time since July 2007, ending near 5.0% (CNBC, Rio Times, 09/17-18).
4. Gold rises despite the dollar and yields. Gold's first weekly gain in four weeks came as oil fell and inflation fears eased; December futures hit a weekly high of $4,439.80 on 09/18 (Yahoo Finance, Bloomberg, 09/18). Levels differ by contract and source, so $4,350-4,440 is the reasonable range.
5. Houthi strikes on Saudi energy facilities. Attacks hit Abha, Khamis Mushait, Jazan and Najran, with fires, temporary shutdowns and a damaged pipeline (CNBC, 09/15). The US said the pipeline would restart within days, and Saudi Arabia rerouted about 2.8M bpd through Hormuz over six days versus 700K bpd in August (CNBC, 09/16-17).
6. Oil snaps a two-week winning streak. WTI settled at $101.91 on 09/17 and Brent at $104.82; Brent fell below $105 on the Saudi export pivot (CNBC, OilPrice.com, 09/17-18), while Macron called for another emergency oil release as Europe loses supply.
7. Russia sanctions bill. The House passed H.R. 5334 262-159 on 09/16, giving the president sweeping tariff powers over Russian oil buyers; reports conflict on whether it is already signed (Steptoe, Investing.com, 09/16-19).
8. Equity dispersion. Growth held up — the Nasdaq Composite rose 0.39% on 09/18 — while the Dow had its worst week since March, a sign of sensitivity to 5% yields outside of AI leaders.

5. Macro Backdrop

Macro

The regime is a hawkish, inflation-driven one with an oil supply shock: a Fed that has started hiking, a 10-year yield at 5%, CPI at 3.4% y/y and WTI up more than 18% on the month. Energy is the direct pass-through from Middle East disruption to inflation and to the Fed. The Fed's next meeting is 10/27-28.

Cross-Asset

Equities are under pressure from yields but AI-led growth holds: S&P flat, Nasdaq 100 +0.9%, Dow -1.5%. Gold is behaving as an inflation hedge that fell earlier on hike pricing and rebounded once the hike was known and oil eased; its usual inverse link to a stronger dollar and higher yields is only partly intact this week. Silver (+3.1%) and miners outperformed gold.

Regulation

The main policy item is the Russia and Iran sanctions bill (H.R. 5334, passed the House 262-159 on 09/16), which would add tariff powers on buyers of Russian energy — bullish for oil-supply risk and inflation. Enactment status is unresolved across sources and should be checked on Congress.gov. No news was found on CFTC futures margin changes, ETF rules or index rebalances; that is a gap, not a confirmed absence.

Rotation / Safe-Haven Cycle

Gold ETFs saw large inflows in early September (GLD +$1.4B, GLDM +$590M) and then a fee-driven shift (GLD -$603M against about +$403M combined in GLDM, IAU and IAUM). The exact dates of those two weeks do not line up with certainty to 09/11-09/18. Gold demand looks mid-phase: it was pressured for three weeks by hike pricing and recovered afterwards.

Sentiment

The VIX at 14.81 is low, while CNN's Fear & Greed reads 29 (Fear), from a third-party aggregator that tracks the CNN index (not CNN's own page). That divergence means the fear comes from momentum, breadth and safe-haven components rather than implied volatility. A hawkish Fed and 5% yields with a calm VIX is a complacency signal.

6. Positioning & ETF Flows

• COT (positions as of 09/15, released 09/18, CME Comex): gold open interest 409,899 with managed-money longs at 142,394; silver open interest 103,745 with managed-money longs at 20,205. Net positions and shorts were not obtained, so crowding cannot be assessed. No WTI managed-money data.
• ETFs: gold ETF flows above (ETF Action, GoldSilver; dates unconfirmed). SLV -$29M in the earlier week. SPY, QQQ and USO flows were not available from a free source this run.

7. What to Watch Next Week

• Mon 09/21: Chicago Fed National Activity Index (August).
• Tue 09/22: Richmond Fed Manufacturing and a $78B 2-year Treasury auction.
• Wed-Fri: PCE and GDP dates were not confirmed; check the FedRateCalc September calendar.
• Fed speakers after the hike and whether the 10-year holds above 5%.
• Saudi pipeline restart and further Houthi strikes; OPEC+ and EIA inventories were not confirmed for the week.
• Sanctions bill: whether the Russia sanctions law is signed. The ban on long-term Russian pipeline gas contracts starts 09/30, when Micron also reports.
