The week of March 9–13 was one of the most consequential in 2026. Iran’s Supreme Leader declared the Strait of Hormuz should remain closed as a weapon of economic pressure, Brent crossed $100 for the first time since 2022, and every major US index printed a new year-to-date low.
The S&P 500 has shed 1.6% this past week alone and is now nursing a three-week consecutive losing streak — the longest since early 2025. The Nasdaq 100 has pulled back more than 15% from its February peak above 25,500, while the Dow Jones sits near 46,474, its weakest close since November. WTI surged 35% in a single week — its largest weekly move in recorded futures history. The IEA’s emergency release of 400 million barrels barely dented the upward move.
⚠ Stagflation Risk Alert
US CPI for February came in at 2.4% YoY, but that predates the oil shock in full. With Brent above $100, economists at multiple banks now estimate CPI could breach 3.5–4.0% by Q2 2026 if the strait remains closed. The Fed walks into its March 17–18 meeting with an inflation problem it can’t cut through and a growth problem it can’t hike through. That is the textbook definition of a policy trap — and markets know it.
The FTSE 100, positioned very differently with its heavy energy sector weighting (BP and Shell both had positive weeks), is navigating this period with considerably more resilience. Down just 0.2% for the week versus S&P’s 1.6%, London’s benchmark is acting as a relative safe haven within equity markets.

⚠ FOMC Preview — Wednesday 18:00 GMT
The rate decision itself is nearly certain to be a hold (92%+). What markets will trade on is the dot plot. If the median projection shifts from one 25bp cut to zero cuts in 2026, expect a sharp selloff in both equities and bonds. Conversely, if the dot plot shifts to two cuts amid war-related growth concerns, risk assets would likely bounce aggressively. Powell’s language around “geopolitical risks to the inflation outlook” will be parsed word by word. Avoid holding large unhedged positions into 18:00 GMT Wednesday.

Three Black Crows (Weekly) — Confirmed
Three consecutive bearish candles with lower closes, each opening within the prior candle’s body. Most reliable continuation pattern in a downtrend. Institutional selling pressure confirmed. Formed March 3–13.
🔻
Bearish Engulfing (Daily, March 13)
Friday reversed an early morning recovery with a bearish engulfing formation — confirms seller control even on attempted relief rallies. Resistance at 22,000 held decisively.
📊
Bearish Divergence on RSI
As price made lower lows from the Feb peak, RSI formed lower divergent peaks. Classic exhaustion signal. RSI approaching oversold (~35–38) may produce short-covering bounce, but not reliable reversal in strong downtrends.
The Nasdaq 100 has entered a confirmed intermediate-term downtrend. After peaking above 25,500 in late February, the index has surrendered more than 15% across three weeks. The break below the 200-day SMA (which held in every prior pullback since May 2025) is the most significant technical event of 2026 so far. Historically, once the Nasdaq loses its 200-day on a confirmed weekly close, the average subsequent drawdown before a sustainable low is established is between 6–12% from the break point.
The 50-day MA (~24,900) and 100-day MA (~24,732) are now well above current price and serve as formidable overhead resistance. Any bounce into this zone should be treated as a potential shorting opportunity under current macro conditions unless the FOMC delivers a dovish surprise or the Hormuz situation resolves suddenly.
Entry Zone (Short)22,000–22,200On failed break + bearish candle confirmation
Stop Loss22,600Above resistance cluster; daily close basis
Target 1 / Target 221,100 / 20,500Previous support structures
Rationale: Primary trade is to sell rallies into the overhead resistance zone at 22,000–22,200 where former support acts as resistance and the 20-day MA likely converges. Wait for a daily candlestick reversal signal (shooting star, bearish engulfing) before entering. Do NOT enter ahead of the FOMC Wednesday. If FOMC is dovish and price gaps above 22,600, re-evaluate — bear case invalidated on sustained break above 22,928.
Conditions: Only activates if FOMC delivers a dovish dot-plot surprise (two cuts projected) AND price holds above 21,400 on the post-announcement reaction. Lower-probability scenario (~20%). R:R remains favourable given oversold RSI. Do not chase this trade if it gaps significantly at open.

📐
200-Day SMA Test Imminent — Watch Carefully
A hammer or doji with high volume at the 200-day followed by bullish engulfing the next day = credible reversal signal. A clean close below with no bullish follow-through over 2–3 sessions = triggers the bear case.
The S&P 500 is in its most technically challenged position since April 2025. A daily close below the 200-day SMA (~6,582) on strong volume would be a major bearish signal — historically preceding average drawdowns of 8–12% over 4–8 weeks. However, on a monthly timeframe, the structural bull market intact since October 2022 is still alive — the current decline has only retraced ~7% from the ATH above 7,100.
Entry Zone (Short)6,680–6,750Wait for failed bounce + bearish candle
Stop Loss6,870Above 50-day MA and resistance cluster
Targets6,520 / 6,400Structural support levels
Rationale: The S&P remains in a distribution phase. Former support at 6,750 and the 50-day MA at 6,856 are now primary resistance. Bounces into this zone on low volume are prime shorting opportunities with clearly defined stop above 6,870. Most likely scenario pre-FOMC (Mon–Tue) is subdued, choppy price action near the 200-day. Post-FOMC (Wed afternoon) the direction becomes clearer.

Bullish SignalHammer / Doji at 200-dayFollowed by bullish follow-through

The 200-day SMA is the market’s line in the sand for 2026. Its defence or failure this week will define positioning for institutional players for the rest of Q1. Watch for volume on any test — high-volume hold is bullish; high-volume break is bearish.

✓ Relative Outperformance Note
The FTSE 100 is outperforming global indices significantly. Its heavy energy weighting (BP +19.6% over 6 months; Shell similarly strong) provides partial insulation from the Iran oil shock that’s crushing US tech. Oil above $100/bbl is a tailwind for London’s biggest constituents. The FTSE behaves as a partial inflation hedge within global equity portfolios.

Bearish Three-Day Sequence (Daily, Mar 11–13)
Three consecutive bearish closes from 10,500 down to 10,254. Each day’s open within the prior candle’s range — confirms methodical institutional distribution rather than panic. Important context for the week ahead.
🔶
Doji / Indecision at Weekly Open (Mar 9–10)
Classic doji formations as FTSE digested conflicting flows between energy (bullish) and banks/housebuilders (bearish). This indecision at 10,400–10,500 effectively marked the “ceiling” before selling resumed.
🔨
Potential Hammer at 50-Day Support — Watch
Watch 10,145–10,177 this week closely. Hammer or spinning top at this zone with bullish follow-through = textbook long setup aligned with longer-term trend. 50-day MA convergence makes it technically meaningful.
The FTSE 100’s technical picture is genuinely bifurcated. In the short term, the index is in a corrective phase after peaking at 10,934.90 on February 27. However, the medium and long-term structure remains constructive — all key moving averages remain below current price. The Bank of England decision on Thursday is the key local catalyst: a 5-4 split vote tilting hawkish would weigh heavily on rate-sensitive sectors; a clean 8-1 dovish hold would be more constructive.

Target 1 / Target 210,500 / 10,700Resistance zone and measured move
Rationale: The FTSE’s 50-day MA at 10,177 has provided meaningful support throughout 2026. With the long-term trend intact, oil acting as a tailwind for energy heavyweights, and a potentially market-friendly BoE hold on Thursday, a long trade at 50-day support offers approximately 3:1 R:R. Key condition: bullish candlestick confirmation at entry (hammer, morning star) — do not enter on a straight down-move through support. Wait for the bounce candle.
Target 1 / Target 210,050 / 9,987200-day MA as downside anchor
Activates only if the BoE delivers a hawkish surprise (MPC 5-4 leaning toward a hike) — which would represent a significant shift in market narrative and trigger rapid repricing of rate-sensitive FTSE sectors.

§ 08 — FAQ
Questions Active Traders Are Asking This Week
Is this a buying opportunity, or are markets going significantly lower?
The honest answer is: it depends on the FOMC outcome and the Hormuz situation. From a pure technical standpoint, the Nasdaq at –15% from its high and the S&P testing its 200-day SMA are levels where historically, medium-term buyers have emerged. However, stagflation environments — particularly ones driven by external supply shocks — can keep markets under pressure for months. 1973 saw the S&P fall 40%. 2022 saw the Nasdaq fall 33%. The structural difference is that earnings remain strong (Evercore has raised its S&P EPS forecast to $304), corporate balance sheets are healthy, and the AI capex cycle is still in progress. For long-term investors, accumulating at current levels in tranches is defensible. For short-term traders, the trend is bearish and should be respected until confirmed reversal signals appear.
How will the FOMC meeting on March 17–18 affect the indices?
The rate decision itself is almost certainly a hold (92%+ probability per CME FedWatch). What matters is the dot plot and Powell’s press conference. Three scenarios: (1) Neutral/hawkish dot plot (zero cuts projected, inflation warnings) → markets selloff sharply, particularly Nasdaq 100. (2) Status quo hold (one 25bp cut still in median projection) → muted reaction, market settles on direction by Thursday. (3) Dovish surprise (two cuts projected, growth concerns cited) → sharp bounce, particularly in rate-sensitive growth stocks. The press conference (18:30 GMT Wednesday) moves markets more than the statement. Watch for any mention of “geopolitical” or “oil prices” — that language alone will signal the Fed’s internal concern level. Avoid holding large unhedged positions into 18:00 GMT Wednesday.
Why is the FTSE 100 outperforming US markets during this oil shock?
The FTSE 100 is structurally better positioned to weather an oil shock than the Nasdaq or S&P 500. Approximately 14% of the FTSE’s market capitalisation is in oil and gas majors (BP, Shell), which benefit directly from higher oil prices. Another significant portion is in mining companies that benefit from the inflationary environment. The index also has far less exposure to high-multiple technology stocks, which are most vulnerable to rising yields and inflation. Furthermore, at a P/E ratio of approximately 14, the FTSE trades at a near-50% discount to the S&P 500 (P/E ~25), meaning there is less valuation compression risk. For global investors looking to rotate away from US tech during the oil shock, the FTSE represents a logical destination. The caveat is the UK domestic economy, which is stalling — January GDP came in flat — and this creates a ceiling on FTSE gains from domestically oriented sectors.
What are the technical triggers that would confirm a market reversal (bullish)?
For the S&P 500, the clearest reversal signal would be a successful defence of the 200-day SMA (~6,582) with a bullish engulfing candle on above-average volume, followed by two consecutive higher closes. For the Nasdaq 100, a sustained reclaim of 22,200 on strong volume would change the short-term bias from bearish to neutral. For the FTSE, a bounce from the 50-day MA (10,177) with a hammer candlestick pattern and bullish follow-through would activate the long setup. In all cases, these signals would be significantly strengthened if accompanied by a dovish FOMC outcome and any de-escalation news from the Middle East.
How should I manage position size given the current macro environment?
This is one of the highest-uncertainty macro weeks of 2026. With three central bank decisions (Fed, BoE, RBA), elevated oil, and VIX near 27, standard position sizing rules call for caution. A practical approach: reduce position sizes by 30–50% versus your normal baseline entering Monday. Do not add to positions in either direction until after the FOMC decision Wednesday. After the decision, re-evaluate the dominant narrative and rebuild positions in the confirmed direction. Widen your stops proportionally to the increased VIX — in a 27 VIX environment, daily index moves of 1.5–2% are routine, and tight stops will get hit even in a direction that ultimately proves correct.
What is the longer-term outlook for the Nasdaq 100 and S&P 500 beyond this correction?
The structural bull case for US equities in 2026 remains intact on a 6–12 month view, but it requires the Iran situation to resolve (or at least stabilise) and oil to retreat from above $100. Corporate earnings are strong — Evercore has raised its S&P 500 EPS estimate to $304, up from $296. The AI capex cycle remains in full swing. Multiple Wall Street strategists have year-end S&P targets in the 7,500–8,000 range. For the Nasdaq specifically, a resolution of the geopolitical risk and a dovish Fed pivot in H2 2026 would be powerfully bullish. Current levels therefore look attractive on a 6–12 month horizon for patient investors. The danger is attempting to call the exact bottom in a week as uncertain as this one.
Editor’s Verdict — Week of March 16–20, 2026
The Week That Could Define 2026 Markets
We are at an inflection point. Three weeks of equity distribution, a historic oil shock, and a Federal Reserve walking into its most consequential meeting of the year have created a market environment where neither blind bulls nor knee-jerk bears are likely to prosper. What will succeed is disciplined, scenario-aware trading with clearly defined entry conditions, stop levels, and targets.
For the Nasdaq 100 and S&P 500, the primary bias is bearish into the FOMC, with the instruction to “sell rallies” rather than chase breakdowns. Both indices have completed technically bearish patterns (Three Black Crows, Bearish Engulfing) and remain below key moving average resistance. The S&P’s imminent test of the 200-day SMA is the single most important technical event of the week — its outcome will likely set the tone for the remainder of Q1.
For the FTSE 100, the picture is different and more nuanced. Long-term signals remain bullish, the oil shock is a structural tailwind for its biggest constituents, and the 50-day moving average support zone near 10,145–10,177 represents a technically sound buying opportunity. The Bank of England on Thursday is the key local risk event.
Above all else this week: manage your risk first. The VIX at 27.28 is telling you something. Central bank decisions on Wednesday (FOMC) and Thursday (BoE) represent binary events that can move indices 2–3% in either direction within minutes. Reduce leverage before these events, wait for confirmation signals, and let the market’s post-announcement structure show you the direction.
