Supply chain pressure surges to post-pandemic highs, oil/gas blockades become new risk source

Overview

UBS reactivated its Global Supply Chain Pressure Index, pointing out that affected by the Middle East conflict, supply chain pressure in spring 2026 is rising at the fastest rate since the pandemic. Unlike logistics interruptions during the pandemic period mainly caused by port labor shortages, the current core bottleneck lies in global oil/gas flow disruption, particularly tanker and LNG transport in Asian waters. This structural change requires re-evaluating inflation risks and economic prospects; UBS believes its new index can better capture this type of new shock.

Core views

Demand Side: Current supply chain pressure stems mainly from energy flow interruptions caused by geopolitical factors, rather than labor shortages during the pandemic period. UBS points out that bottlenecks are concentrated in tanker and LNG transport in Asian waters, directly affecting global energy supply. Supply Side: UBS adjusted its Supply Chain Pressure Index, significantly increasing weights on Asian-related shipping costs, tanker, and LNG ship satellite tracking data, while reducing reliance on traditional PMI delivery time data. The new indicator is closer to the constraint nature of 'Energy Flow' rather than 'Goods Flow'. Price Transmission: Index rise signals that energy prices (especially Asian markets) may continue to face pressure, transmitting to global commodity prices through production costs and transportation costs, increasing upside inflation risks. Data Support: Between March and April 2026, the index rose by 1.2 standard deviations, the largest two-month increase since the July 2020 pandemic impact. Satellite tracking data shows significant reduction in tanker and LNG ship transport volume in Asian waters, synchronized with the index surge.

Analysis framework

UBS's analytical approach identifies a structural shift in supply chain shocks. In the early stages of the pandemic, constraints were mainly on 'Port Labor', so the World Bank container tracking index was an effective tool. However, now, constraints have shifted to 'Energy Flow', specifically oil/gas transport on the Middle East-Asia route. Therefore, instead of following old indicators, UBS proactively reconstructed the index, introducing satellite-tracking tanker and LNG ship activity data combined with Asian shipping prices, creating an 'Energy Supply Chain Pressure' indicator that better reflects new geopolitical risks. This methodology reflects a shift from 'Post-event Tracking' to 'Forward-looking Capture': Instead of relying on lagging PMIs or port congestion data, it directly tracks physical flow interruptions. This makes the index a unique tool for monitoring geopolitical impacts on the global economy, where its rise signals point to inflationary pressure earlier and more directly than traditional indicators. Its analytical logic is clear: New Shock (Oil/Gas Blockade) -> New Data Source (Satellite Tracking) -> New Indicator (Reconstructed Index) -> New Conclusion (Exacerbated Inflation Risk).

Methodology notes

• Industry/Industrial Analysis FrameworkSupply-demand framework

  Reconstruction of supply chain pressure indicators based on judgment that core constraints have shifted from 'Goods Flow' to 'Energy Flow'

  UBS believes the core of current supply chain bottlenecks is the obstruction of global flows of key energy such as oil/gas, rather than delays in commodity transportation. Therefore, they shifted the focus of indicator construction from measuring 'whether goods can be delivered on time' (Old Model) to measuring 'whether energy can be delivered as needed' (New Model), reflecting precise identification of changes in the core contradictions of industry supply and demand.

• Industry/Industrial Analysis FrameworkUpstream/Midstream/Downstream Chain Transmission

  Directly measure energy transport interruptions in Asian waters by tracking tanker and LNG ship activities via satellite

  UBS did not rely on indirect port data or freight price indices but directly used satellite images to track the movement trajectories of tankers and LNG ships. This is the most direct monitoring means for the upstream of the industry chain (energy production and transport), able to capture supply interruption signals earlier and more truly, and transmit them to downstream inflation and economic activity forecasts.

• Industry/Industrial Analysis FrameworkVolume-price decomposition

  Decompose supply chain pressure into price (shipping cost) and volume (ship activity) dimensions for comprehensive measurement

  UBS's index incorporates both shipping prices (such as Baltic Index) and ship physical traffic (satellite tracking data), which helps distinguish whether pressure stems from 'freight rates skyrocketing' (price factor) or 'fundamental transport interruptions' (volume factor). Current data shows simultaneous deterioration of both, indicating the shock is substantial, not merely cost increases.

• Industry/Industrial Analysis FrameworkSubstitution Effect Analysis

  Compare and critique existing FRB New York and World Bank indices, believing their sensitivity to current shocks is insufficient

  UBS points out that the FRB New York index relies too heavily on PMI data, while PMI reflects purchasing managers' expectations, reacting laggingly to sudden geopolitical events; World Bank index only tracks container ships, unable to capture tanker and LNG ship interruptions. UBS demonstrated the necessity of its new indicator through this comparison, reflecting a clear understanding of limitations in existing analysis frameworks.

Asset mapping & comparison

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

• Crude Oil

  Benefited from supply chain pressure rise, as transport disruptions caused by Middle East conflict drove up global oil price expectations

  Strengths

  As a core blocked commodity, its price is highly sensitive to transport bottlenecks

  Comparison

  Compared to natural gas, crude oil's global transport network is more complex, affected by geopolitical factors over a wider range

  Risks

  If conflict eases and transport resumes, oil prices may fall rapidly

• LNG

  Benefited from supply chain pressure rise, as LNG ship transport disruptions in Asian waters directly affect regional supply security

  Strengths

  Asia is the main consumption market, transport disruptions directly lead to regional shortages and price spikes

  Comparison

  Compared to crude oil, LNG transport and infrastructure are more concentrated, higher dependency on specific routes (e.g., Middle East-Asia), risks are more concentrated

  Risks

  Use of alternative energy (such as coal) may partially offset LNG shortage impacts

• Global Shipping Companies

  Detracted from supply chain pressure rise, as transport interruptions indicated by index may forecast future cargo demand decline and increased operational uncertainty

  Weaknesses

  Their business relies highly on smooth global trade, while current supply chain pressure is a systemic risk

  Comparison

  Compared to companies focusing on container transport, those focusing on energy transport may benefit short-term, but long-term prospects dragged by geopolitical risks

  Risks

  Prolonged geopolitical conflicts will lead to rising shipping costs and route changes, eroding profits

Impact & implications

UBS believes that the rapid rise in supply chain pressure, especially oil/gas transport obstruction, will have a significant negative impact on the global economy. This may lead to sustained high energy prices, exacerbate global inflation pressures, forcing central banks to maintain tighter monetary policy. At the same time, rising energy costs will transmit to manufacturing and logistics industries, inhibiting global trade and economic growth. The spike in this index is a clear signal of resurging inflation risks, potentially changing market expectations for economic cycles and policy paths.

Risks

• Prolonged Middle East conflict leads to sustained oil/gas transport interruptions, inflation pressure far exceeding expectations
• Global central banks adopt more aggressive tightening policies to cope with inflation, triggering economic recession risks
• New methodology of supply chain pressure index widely accepted by market, but predictive capability still needs time verification

What to watch

• Whether the reading of the next issue (June 2026) Supply Chain Pressure Index continues to climb
• Whether satellite tracking data for tankers and LNG ships in Asian waters shows transport volume recovery
• Reaction strength and persistence of international oil and natural gas prices to current pressure
• Whether inflation data from major economies (e.g., US, Eurozone) shows signs of resurgence
