Rate volatility, AI capex discipline, and upstream oil and gas investment become the main themes this week

Overview

This is a Goldman Sachs weekly equity research roundup that connects cross-sector variables such as rates, AI investment, data centers, electrification, oil and gas capex, and supply-chain disruptions to identify actionable research ideas for the week. The report is not centered on a single company; instead, it presents multi-asset and multi-region investment signals through macro, industry, and stock-specific research summaries.

Core views

First, long-end rates and bond yield volatility are again key drivers of equities, credit, and portfolio risk, and the historical behavior of defensive sectors and momentum styles may not hold. Second, AI remains a central market theme, but investors need to distinguish true beneficiaries from use cases with unclear capex returns; data centers, power, grid infrastructure, semiconductors, and behind-the-meter solutions are the main beneficiary chains. Third, signals tied to oil and gas exploration are starting to recover, and seismic service supply contraction, fleet aging, and industry consolidation may create a pricing cycle for upstream service companies such as TGS. Fourth, weak European macro growth, energy prices, and supply-chain pressure continue to affect inflation, airline costs, industrial margins, and consumer performance.

Analysis framework

The report uses a 'theme linkage plus research picks' approach: it first establishes the macro and industry backdrop through three main threads—rates, AI investment discipline, and oil and gas capex—and then lists Goldman Sachs teams' key research conclusions across sections such as AI, rate volatility, energy security, rating changes, sector updates, buy/sell reiterations, earnings, and events. Its investment implication is more about filtering directions and highlighting risks than about providing a unified valuation model.

Methodology notes

• cross-asset macro frameworkrates-equity correlation and yield shock

  Use long-end Treasury yields, equity-bond yield correlations, and credit spread demand structure to determine the source of pressure or resilience in risk assets.

  The report emphasizes that the 30-year U.S. Treasury yield breaking above 5% and the two-month correlation between U.S. equities and 10-year Treasury yields turning the most negative since the 1990s means the direction and cause of rate moves will directly affect equities, credit, and portfolio risk.

• theme investing frameworkAI capex discipline

  Differentiate mandatory AI infrastructure spending, enterprise application economics, and capital return discipline.

  The report argues that there are still investment opportunities in data centers, power, grid infrastructure, semiconductors, and GPU supply-demand, but the losses associated with enterprise AI implementation, token growth, and the sustainability of indiscriminate AI adoption need to be assessed cautiously.

• cycle and supply-demand frameworkoil and gas exploration capex cycle

  Assess the upstream capex cycle by tracking changes in mentions of exploration, seismic, discoveries, and acreage on earnings calls, as well as shifts in seismic vessel supply.

  The report notes that related mentions have rebounded materially; seismic services are typically an early stage of upstream oil and gas spending. At the same time, the number of active vessels has fallen markedly from 2013 levels and the fleet is aging, supporting the case for better seismic service pricing.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• AI data center and semiconductor chain

  Benefiting from AI capex, GPU demand, European data center buildout, and electrification investment.

  Strengths

  Nvidia's strong guidance, rising GPU rental prices, and Vera CPU creating new TAM are all positive signals; European hardware and semiconductor names such as ASML, ASMI, BESI, Infineon, and NBIS are mentioned as beneficiaries.

  Weaknesses

  The economics of enterprise AI applications remain disputed, and if AI spending fails to generate returns, the sustainability of capex could be repriced by the market.

  Comparison

  Compared with software and broad AI applications, the report places more emphasis on hardware, data centers, power, and infrastructure as the more certain areas.

  Risks

  Token growth coming in below expectations, persistent losses in enterprise AI deployment, capex cuts, and valuation crowding.

• European utilities, clean energy, and electrification assets

  Data center and power security demand are driving investment in electricity, grid infrastructure, and behind-the-meter solutions.

  Strengths

  Enel, Naturgy, Siemens Energy, and Ceres Power are described as relevant beneficiaries, and gaps in Europe's power infrastructure increase the investment case.

  Weaknesses

  Grid bottlenecks, regulatory constraints, and slower macro growth may limit project execution speed.

  Comparison

  Compared with pure macro energy exposure, electrification and data-center-related assets are closer to structural demand.

  Risks

  Higher rates raising the cost of capital, policy or permitting delays, and stagnation in Europe.

• Oil and gas exploration and seismic services

  An upcycle in oil and gas capex and constrained seismic service supply could benefit TGS.

  Strengths

  Exploration-related keywords have rebounded rapidly on earnings calls; after acquiring PGS, TGS has vessels, and industry consolidation plus no new builds support better pricing.

  Weaknesses

  Demand still depends on upstream capex from oil and gas companies, and cycle inflection points are confirmed with a lag.

  Comparison

  Seismic services typically reflect capex improvement earlier than other oil service segments, making them an early indicator of the exploration cycle.

  Risks

  Lower oil prices, project delays, energy transition pressure, and weaker-than-expected vessel utilization.

• Long-duration bonds, credit, and equity portfolios

  Rate volatility affects equity valuations, credit total returns, and investor risk appetite.

  Strengths

  Income-oriented buyers such as pensions and insurers provide deep demand for corporate bonds, helping credit spreads remain resilient.

  Weaknesses

  High yields pressure total returns for 2026, and a stronger negative correlation between equity and bond yields increases portfolio volatility.

  Comparison

  The report argues that the drivers of rate moves matter more than direction alone, especially for credit spreads and risk appetite.

  Risks

  Deterioration in the growth-inflation mix, energy price shocks, and further increases in bond yields.

Key data

• Report date2026-05-22The cover page shows Equity Research and a timestamp of 1:41PM BST.
• 30-year U.S. Treasury yieldabove 5%The report says rate dynamics are dominating market discussion, and global yields are also moving higher.
• H100/A100 GPU rental pricesup 20%/15% year to dateUsed to illustrate AI compute demand and Nvidia guidance feeding positively into the European AI hardware beneficiary chain.
• Vera CPU potential marketapproximately $200bnThe report says Vera CPU opens a new TAM related to CPU demand.
• Seismic fleet supplydown from about 60 vessels in 2013 to roughly 17-30 currentlyThe report says there have been no new builds since 2017 and the fleet is aging, supporting the upward pricing logic for seismic services.
• European jet fuel importsdown about 60% versus the 2025 averageThe report believes that if jet fuel costs remain at current levels, Ryanair's FY27 unit costs would rise by a mid-single-digit percentage.
• U.S. insurance and pension holdings of corporate bonds$6.4 trillion combined as of 4Q25Used to show the support provided by income-oriented buyers for the resilience of corporate credit spreads.
• Progress of Europe's 1Q26 earnings seasonabout 75% completeThe report says earnings beats are still positive, but they are concentrated in financials and commodities, while misses are being punished more severely.

Impact & implications

For portfolios, the report points to greater selectivity: AI and data center chains still offer structural opportunities, but investors should prioritize companies with pricing power, order visibility, and a clear path to capital returns; oil and gas exploration and seismic services may be in an early cycle phase, where supply constraints can amplify upside; meanwhile, rising long-end rates, energy costs, supply-chain disruptions, and slower European growth will weigh on high-valuation, low-pricing-power, or highly leveraged companies.

Risks

• Further increases or greater volatility in long-end rates could compress equity valuations and weigh on credit and multi-asset portfolio returns.
• Unclear returns on AI capex, losses in enterprise AI applications, or indiscriminate expansion could lead the market to re-evaluate AI-theme valuations.
• Energy supply disruptions and sustained high oil and jet fuel costs could hurt airlines, consumer companies, and European macro growth.
• European growth may approach stagnation or even contract, and higher-than-expected energy prices would amplify downside risks.
• Supply-chain pressure and raw material inflation could hurt industrial, chemical, and consumer companies that cannot pass through costs.
• Narrow market breadth and crowded momentum trades could increase drawdown risk.

What to watch

• Whether the 30-year U.S. Treasury yield stays above 5% and how the correlation between U.S. equities and 10-year Treasury yields evolves.
• Capital expenditure from AI-related companies, GPU rental prices, Vera Rubin shipment progress, and realization of Vera CPU demand.
• European data center projects, grid investment, power security policy, and electrification orders.
• Whether mentions of seismic, exploration, discoveries, and acreage continue to rise in oil and gas earnings calls.
• Whether TGS sales recover in 2H26 as expected and whether seismic service prices enter an upcycle.
• Energy prices, European jet fuel imports, and unit costs and guidance for airlines such as Ryanair and easyJet.
• The rest of Europe's 1Q26 earnings season, especially market reactions to financials, commodities, capital goods orders, and companies that missed earnings expectations.
