Citi Global Strategy: AI Infrastructure Bottlenecks Shift; Focus on Supply Chain and Regional Banking Divergence

Overview

This edition of Citi’s Global Core Recommendation focuses on structural opportunities and risks against the backdrop of global economic resilience. The report argues that AI infrastructure investment remains robust, with bottlenecks shifting toward system-level execution—benefiting select segments of the supply chain. It also reviews company-specific developments across Korea, the Middle East, and Europe, highlighting divergent competitive dynamics and earnings prospects among regional banking markets.

Core views

AI infrastructure constraints are shifting toward system-level execution. NVIDIA’s latest quarterly revenue reached $81.6 billion, accompanied by a strong forward guidance of $91 billion, reflecting sustained robust demand from hyperscalers for Blackwell systems and Rubin architecture. Management emphasized the company’s transformation into an “AI factory,” with notable growth in networking equipment, NVLink interconnects, and rack-scale systems. Crucially, supply chain bottlenecks have expanded beyond chip manufacturing to encompass the full data center infrastructure stack—including HBM memory, CoWoS packaging, substrates, and optical components. This evolution benefits downstream manufacturers with end-to-end system delivery capabilities—such as Foxconn and Delta Electronics—and provides NVIDIA greater visibility into supply allocation for 2026–2027. Labor risk temporarily resolved at Korean tech giant. Samsung Electronics and its union reached a provisional agreement on wages, benefits, and a new 10-year performance bonus plan for the DS division, with all bonuses to be paid in treasury shares. Estimated total employee incentives amount to approximately 12% of annual operating profit. Though only provisional, this agreement meaningfully reduces market concerns over potential strike-related production disruptions and buys time for formal negotiations. Saudi banking exhibits pronounced structural divergence. Small- and medium-sized enterprises (MSMEs) form a core pillar of Saudi Arabia’s Vision 2030. Citi’s proprietary model forecasts MSME loan growth at a ~15% CAGR through 2029, lifting their share of total loans to ~14%. Riyad Bank and SNB—leaders in MSME lending—are designated top picks. In contrast, Alinma Bank expects lackluster Q2 results and may downgrade its full-year ROE guidance to 17.9% (below its prior target of >19%), driven by higher operating expenses—potentially weighing on its stock in the near term. European banking faces deposit competition and valuation re-rating. JPMorgan Chase (Chase) entered the German retail deposit market with a leading 4% rate, intensifying local deposit acquisition pressures. For ING, each 10-percentage-point rise in German deposit beta translates to ~2% headwind to net interest income. Thus, ABN AMRO holds relative advantage short-term due to its lower need for expensive deposit funding. By contrast, following discussions with business-line leaders, Danske Bank confirmed its 2028 targets remain prudent and achievable. Citi forecasts its ROE at 15.2%, reaffirming its status as Citi’s top pick in Nordic banking.

Analysis framework

The report employs a 'macro theme + micro validation' analytical framework. In the AI sector, it dissects NVIDIA’s earnings call—including revenue guidance, inventory commitments ($119 billion), and management commentary—to identify the migration of bottlenecks from discrete chips to system integration, then derives implications for downstream assembly players. In regional banking analysis, it combines top-down policy objectives (e.g., Saudi Vision 2030) with bottom-up financial modeling (e.g., deposit beta sensitivity, OpEx erosion of ROE) to distinguish industry-wide growth trends from idiosyncratic operational risks.

Methodology notes

• Industry/Value Chain Analysis FrameworkUpstream-Midstream-Downstream Transmission

  AI Infrastructure Bottleneck Migration Analysis

  Analyzes how bottlenecks shift from upstream core components (GPUs) to midstream packaging/testing and downstream system integration, thereby identifying changes in value creation along the value chain. When upstream capacity gradually ramps up while downstream delivery capability becomes the new constraint, vertically integrated or system-delivery-capable firms gain pricing power and earnings optionality.

• Financial Industry-Specific MetricNet Interest Margin (NIM) Analysis

  Deposit Beta Sensitivity Testing

  Quantifies the lagged responsiveness of bank deposit costs to market interest rate changes. In this report, the institution estimates the precise impact of shifts in German deposit beta on ING’s net interest income, assessing the magnitude of profitability pressure triggered by new entrants’ competitive deposit pricing.

• Corporate Fundamentals & Financial FrameworkROIC–WACC spread

  ROE Target Feasibility Validation

  Validates management’s long-term ROE targets by comparing them against analyst forecasts of cost-to-income ratios and returns on capital across business segments (retail, corporate, wholesale). If forecasted values exceed targets under conservative assumptions, it establishes a margin of safety for investment.

Impact & implications

For the AI supply chain, investors should broaden focus beyond GPU shipment volumes to system-level delivery capability and supporting non-GPU components—enhancing visibility for assembly and power management segments within the Taiwan supply chain. For global banking, differentiation is critical: in Saudi Arabia, prioritize banks with high MSME exposure and avoid names facing near-term earnings pressure; in Europe, monitor intensifying cross-border deposit competition from U.S. banks, favoring domestic institutions with stable liability bases or proven digital transformation success.

Risks

• Slower-than-expected AI infrastructure build-out or technological roadmap shifts
• Breakdown in Samsung Electronics’ formal labor negotiations triggering actual strikes
• Rising non-performing loan rates in Saudi SME lending
• Uncontrolled deposit competition in Europe materially compressing banking net interest margins
• Geopolitical conflict (e.g., Iran situation) dampening global manufacturing sentiment

What to watch

• Deployment pace and system delivery progress of NVIDIA’s next-generation Rubin architecture
• Progress on signing Samsung Electronics’ DS division formal labor agreement
• Alinma Bank’s Q2 2026 earnings report and updated full-year earnings guidance
• German retail deposit rate trajectory and shifts in ING’s deposit beta
• Improvement in cost-to-income ratios across Danske Bank’s business lines
