Global Markets Rally Into May as Fertiliser Fears Meet Falling VIX

The last time we saw the yen-oil correlation this tight was late 2021, right before energy markets and currency markets started moving in lockstep ahead of the Russia-Ukraine invasion. Back then, the correlation unwound violently once the supply shock actually materialized. Today's setup rhymes, though the parallel is loose: a Middle East conflict is driving energy prices, the yen is once again dancing with crude, and Japanese authorities just intervened in the currency market. The Nikkei 225 managed only a 0.38% gain today, a muted response compared to the rally in Western markets, and that divergence suggests Japanese equities are caught between a weaker yen (which normally boosts exporters) and the rising import costs that intervention is meant to address. The 2021 episode reminds us that these correlations tend to snap rather than fade.

But here is the thing. On this Friday morning, most of the world's equity markets are green, the VIX has dropped over 10% to 16.89, and the S&P 500 is sitting at 7,209, up about 1% on the session. Small caps are leading, with the Russell 2000 up 2.21%. Even European markets joined the party: the FTSE rose 1.62%, boosted in part by strong UK banking results (more on that below), while the DAX gained 1.41%. The mood feels oddly upbeat for a world dealing with a widening Middle East conflict and renewed Somali piracy.

So what is driving this disconnect between headlines and price action? Let me walk through it.

The Fertiliser Signal and What It Actually Means

The most important headline this morning is not about stock prices. It is about food. The CEO of Yara, one of the world's largest fertiliser producers, warned that the Iran conflict could put 10 billion meals a week at risk by disrupting fertiliser supply chains. That is not abstract. Fertiliser shortages reduce crop yields, which pushes food prices higher, which feeds directly into inflation data that central banks are watching.

As I discussed in Oil Tops $125 as Stagflation Fears Test AI Leadership: Thursday Market Research Analysis, the stagflation scenario is the one that gives markets the most trouble: rising commodity prices combined with slowing growth. Oil company profits are so large that European nations are reviving windfall tax proposals, echoing the 2022 energy crisis playbook. Meanwhile, Indian Oil just raised LPG and jet fuel prices, a concrete signal that energy cost pass-through is happening in emerging markets. And Woodside, one of Australia's largest LNG producers, is struggling to secure buyers for its U.S. LNG because its pricing strategy has backfired in the current volatile market. That headline matters because it shows how conflict-driven pricing distortions ripple through the entire energy supply chain, creating both winners and losers in unexpected ways.

Yet equities are rallying. Why?

Three forces are doing the heavy lifting. First, VIX compression. When volatility falls this sharply (down over 10% in a single session), it mechanically forces systematic strategies, especially volatility-targeting and risk-parity funds, to add equity exposure. That creates buying pressure regardless of fundamentals. Second, markets have been pricing in Iran-related risk for weeks now, and the absence of a fresh escalation overnight allowed some of that accumulated pressure to release. This is the classic pattern: geopolitical shocks are treated as transitory until hard economic data (GDP, payrolls, earnings) actually deteriorates. Third, the breadth of the rally tells us something. Small caps (Russell 2000 up 2.21%), mid caps (MDY up 1.66%), and international developed markets (VEA up 2.56%) all outperformed large-cap tech. That is a re-risking signal, not a flight to quality. Investors are rotating back into the parts of the market they had been avoiding, which suggests positioning was very defensive coming into today.

Bitcoin rebounding above $77,000 tells a similar story: risk appetite is up, though headlines note that Iran risks are capping upside and preventing a full breakout.

European Banks Deliver the Goods

One catalyst the original equity rally framework misses is what happened in European banking. NatWest posted Q1 profit that beat forecasts and raised its income outlook to the top of its guidance range. Bank of Ireland reaffirmed its 2026 guidance as bad loans dropped and lending climbed. These are not just colorful earnings stories. They are concrete evidence that the bank profitability thesis is working across geographies: steeper yield curves and resilient loan books are translating into better-than-expected results. That is directly relevant to the financials discussion below, and it helps explain why the FTSE outperformed today.

Meanwhile, UK house prices rose in April despite the Iran war headwinds, according to Nationwide. That is another data point suggesting the real economy in the UK is holding up better than sentiment would suggest.

Piracy, Shipping, and the Supply Chain Thread

The piracy resurgence off Somalia is worth watching closely. At least four vessels have been hijacked in recent weeks, and reports link it to the broader Iran conflict destabilizing the region. This is not just a colorful news story. Shipping disruptions through the Gulf of Aden and the Strait of Hormuz are exactly the kind of supply chain friction that keeps energy and goods prices elevated even when headline demand softens. For research subjects tied to global trade flows, this matters.

What Today Means for Active Research Subjects

Let me run through all nine subjects currently under study, grouped by how they performed. A reminder: what follows is observational research output, not personalized investment advice. Readers should consult an authorized financial advisor before making any decisions.

Leaders

BAC (Bank of America), up 8.26% from entry at $53.46. The best-performing active research subject by a wide margin. The steepening yield curve is supporting bank margins, and the NatWest and Bank of Ireland results from Europe this morning reinforce the thesis that the banking earnings cycle is healthy across developed markets. The health review flags minor concerns because the price is now approaching the base case target, which means the risk-reward from here is more compressed. The 5-year Treasury yield fell 1.03% today to 4.023%, and the 10-year sits at 4.39%. That spread continues to be supportive for bank profitability.

EWY (South Korea ETF), up 4.42% today. This is the standout single-day performer among all active research subjects this morning. South Korean equities are being driven by the memory semiconductor cycle, with Samsung and SK Hynix benefiting from AI-driven demand. There are minor concerns around trade tension risks, and I will be honest: the initial confidence on this entry was just 42%, which is below the 55% hard floor that has historically separated positive from negative outcomes. The strong price action so far is encouraging, but I am keeping a close eye on the low initial confidence as a risk factor.

EWT (Taiwan ETF), up 3.09% today. A solid session for Taiwan exposure. The thesis continues to benefit from semiconductor supply chain momentum. Notably, with Hong Kong's Hang Seng down 1.28% and Korea's KOSPI down 1.38% at their local closes, Taiwan's ETF strength today reflects U.S.-listed revaluation rather than a broad Asian rally. That divergence is worth monitoring. The geopolitical escalation risk involving Taiwan and China remains a background concern.

Steady Performers

PEP (PepsiCo), up 0.91% from entry at $158.49. Consumer staples gained 1.68% today via XLP, and PepsiCo is tracking that move. With food inflation back in the headlines thanks to the Yara fertiliser warning, consumer staples companies with pricing power become more interesting, not less. The thesis as a defensive anchor with strong earnings growth and a 3.6% yield continues to hold.

ADBE (Adobe), up 0.27% from entry at $246.10. Adobe is a company with 29.5% net margins and $9.3 billion in free cash flow, and the current valuation remains, in my observation, one of the cleaner value setups in software. The S&P 500 Information Technology sector actually fell 0.63% today, confirming that the broader rally is being driven by cyclicals and defensives rather than tech momentum. Adobe does not need a tech rally to work. It just needs the market to stop ignoring its cash generation. A previous research entry on ADBE closed for a small negative outcome of -1.49% after the trailing stop triggered, despite the price having reached 5.5% gains at peak. That experience taught us that trailing stops on volatile names may need to be wider.

PFE (Pfizer), down 1.11% from entry at $26.70. Healthcare had a strong day, with XLV up 2.21%. Pfizer's thesis rests on its 6.37% yield and cash generation providing a floor, and the defensive rotation happening today is exactly the kind of environment where that thesis gets tested. The modest drawdown does not concern me given the defensive profile.

GS (Goldman Sachs), down 0.24% from entry at $923.77. Financials had a quieter day than expected, with XLF up just 0.40%, which is interesting given how strongly the broader market rallied. The European banking results from NatWest and Bank of Ireland suggest the capital markets recovery thesis has legs, and Goldman's forward earnings with 24% earnings growth still looks reasonable at current levels. As I explored in Where to Invest When Treasuries Compete With Stocks: Navigating the Yield Curve in April 2026, the current rate environment creates both challenges and opportunities for financials.

Laggards and Watchlist

META (Meta Platforms), down 2.85% from entry at $611.91. Meta is the weakest active research subject by delta, which is notable given the risk-on tone today. Tech underperformed the broader market, with the S&P 500 IT sector down 0.63% while the index rose 1.02%. The thesis at forward earnings with 24% revenue growth and 30% margins remains intact, and the valuation discount to peers is hard to justify on fundamentals alone. Sometimes the best setups take patience. But the tech sector weakness is a headwind worth acknowledging.

AMGN (Amgen), down 1.36% from entry at $346.25. Healthcare's strong day (XLV up 2.21%) should be supportive, but Amgen is lagging slightly. The health review flags minor concerns around the company's high debt-to-equity ratio and an upcoming earnings report. Defensive single-stock picks labeled "low risk" based on valuation alone can still face sharp drawdowns when binary catalysts like earnings emerge.

Closing the Books on NVDA, MSFT, TSM, and BABA

Four research subjects closed this week, and all four produced positive observed outcomes. NVDA closed today at a +5.80% gain after the trailing stop triggered when the price pulled back from a peak gain of 14.8%. MSFT also closed today at +9.19%, dropping from a peak of 15.9%. Both were trailed out after strong runs. TSM closed last week at +20.28% after hitting its target price, which was the strongest single outcome in this cycle. BABA closed at +4.80% after its trailing stop triggered from a 12.2% peak.

These exits confirm a pattern observed repeatedly: large-cap tech bought at significant discounts to 52-week highs with strong fundamentals tends to produce positive outcomes. The hit rate across these closed sets continues to be encouraging in that segment.

Gold and the Central Bank Signal

One more thread worth pulling. Countries are stocking up on gold, with central banks buying reserves as the Middle East conflict widens. This is a structural trend, not a trade. When central banks diversify away from dollar reserves into gold, it reflects a shifting view on geopolitical risk and dollar hegemony that operates on a much longer timeline than equity markets. The practical implication: if central bank demand continues to put a floor under gold prices, it signals that the institutional world is pricing in a less dollar-centric future. That has implications for real yields, the dollar, and eventually for how we think about reserve currency dynamics affecting everything from Treasury demand to emerging market debt. It is worth watching as context for everything else happening right now.

What I Am Watching Next

The fertiliser story is the one I keep coming back to. Markets can absorb elevated oil prices for a while. They can absorb shipping disruptions. But if food inflation re-accelerates because fertiliser supply is genuinely impaired, that changes the calculus for central banks in a way that directly affects every research subject I track. The question is whether the Yara CEO's warning is a worst-case scenario or a base case. I will be watching commodity data closely over the coming days.

The second thing I am watching is the divergence between breadth and tech. Today's rally was led by small caps, mid caps, and international markets. Tech lagged. If that pattern persists, it suggests a regime shift in market leadership that would favor value and cyclical exposure over the growth names that have dominated for years. One session does not make a trend, but it is worth noting.
