Tariff-Driven Systemic Risk: Hidden Interdependencies in Global Finance

After engaging with risk leaders at six global forums across three continents, one theme stands out: new forms of risk are emerging almost daily — and tariffs are among the most consequential.

Across G-SIBs and leading institutions, the uncertainty introduced by evolving trade policies has become a persistent source of financial and operational stress.

• Automotive sector: U.S. tariffs on imports from Canada and Mexico have disrupted integrated production chains, amplifying credit and supply chain risk across North America.

• Asian trade finance: New tariffs on Southeast Asian exports — particularly in electronics and steel — are heightening compliance and regulatory risk for banks facilitating cross-border trade.

  
  

These cases illustrate how tariffs cascade through counterparties, supply chains, and portfolios, often in ways that traditional risk models fail to capture. In a globally interconnected market, investors can face exposure even when the initial disruption originates with a third party.

Backward-looking insights are no longer sufficient — today’s environment demands forward-looking, explainable intelligence that can map interdependencies and anticipate where stress will emerge next.

Tariffs as Catalysts for Visible and Hidden Systemic Risk

Tariffs introduce a volatile mix of risks - some that can be seen and many that seem to come out of nowhere. A new tariff shock can ripple through supply chains, client balance sheets, and trading markets before conventional models or dashboards register the impact. While most organizations focus on the immediate cost implications, the secondary and tertiary effects are often far more consequential — amplifying credit, liquidity, market, and operational exposures.

For financial institutions, these risks are deeply interconnected and evolve dynamically across portfolios, sectors, and jurisdictions. 

Escalating Interconnected Risks Across Traditional Domains

As tariff policies evolve and geopolitical tensions intensify, global financial institutions face a new layer of interconnected risks that extend well beyond traditional market dynamics. The following examples illustrate how tariff exposure manifests across multiple risk categories:

• Market and Credit Risk from Global Supply Chain Disruption — Tariffs exert upward pressure on input costs across global supply chains, compressing corporate margins and weakening profitability—particularly in manufacturing, automotive, and technology sectors. At the same time, tariff-driven uncertainty amplifies market volatility. Equity and commodity valuations react sharply to policy announcements, affecting trading-book performance, derivatives exposure, and collateral quality.

  
  

• Liquidity and Funding Risk from Capital Flow Shifts — Trade tensions and tariff uncertainty often trigger flight-to-quality behavior, disrupt currency stability, and dampen cross-border capital flows. Sustained tariff disputes require heightened monitoring of currency risk, liquidity coverage, and funding concentration metrics to preserve resilience under volatile market conditions.

  
  

• Operational and Compliance Risk from Regulatory Fragmentation — Tariffs frequently emerge alongside broader geopolitical realignments and retaliatory trade measures, fragmenting the regulatory landscape across key markets. The result is a patchwork of overlapping and, at times, conflicting trade, sanctions, and financial reporting regimes that global banks must navigate simultaneously.

Hidden Interdependencies and Emerging Second-Order Risks

While tariffs are often assessed in isolation, their indirect effects can trigger a chain of second-order risks that quietly accumulate across counterparties, balance sheets, and jurisdictions. These latent exposures often remain undetected until they manifest as liquidity stress, valuation loss, or governance failures.

• Counterparty and Contagion Risk - Tariffs ripple through multi-tier supply chains, creating indirect exposures that extend far beyond a bank’s immediate client base. When upstream suppliers or downstream distributors face margin compression, liquidity strain, or defaults, the effects can cascade across counterparties—transmitting stress through credit lines, trade receivables, and derivative exposures.

• Balance Sheet and Collateral Valuation Risk - Tariff-driven fluctuations in commodity prices, exchange rates, and trade volumes can quietly erode the value of pledged collateral and distort balance-sheet integrity. As underlying asset prices shift, loan-to-value ratios and collateral coverage metrics can deteriorate without immediate visibility, particularly in capital-intensive sectors such as manufacturing, shipping, and commodities trading.

• Geopolitical and Regulatory Divergence Risk - As tariff actions trigger retaliatory trade measures and region-specific policy shifts, banks must operate within an increasingly fragmented regulatory landscape. Divergent trade rules, disclosure obligations, and sanctions enforcement standards across jurisdictions compound compliance complexity and elevate the risk of inadvertent breaches or governance failures in cross-border operations.

Why Current Models Miss Complex Tariff Risk Interdependencies

Traditional financial risk models are calibrated to quantify what is observable and statistically measurable. Yet tariff dynamics introduce a network of indirect, nonlinear exposures that fall well outside those conventional boundaries.

Surprising Second- and Third-Order Effects - Traditional exposure models typically stop at the first order of impact, capturing only direct client or counterparty risk. They fail to trace how tariff shocks propagate through multi-tier supplier and customer ecosystems, where dependencies are opaque and nonlinear. The distress or default of an upstream supplier or downstream distributor can transmit losses across portfolios unexpectedly—even when directly exposed firms appear financially sound. 

Dynamic, Nonlinear Market Reactions - Tariffs introduce abrupt, feedback-driven shifts in pricing, hedging, and trading behavior that static, correlation-based models fail to anticipate. Market sentiment, algorithmic trading responses, and policy countermeasures can amplify volatility in nonlinear and self-reinforcing ways.

Cross-Jurisdictional Regulatory Divergence - Tariffs rarely operate in isolation; they often trigger retaliatory trade actions and evolving compliance regimes across multiple jurisdictions. This fragmentation creates a patchwork of overlapping and sometimes conflicting regulatory requirements. Conventional risk models overlook how such regulatory divergence heightens operational and legal exposure—particularly for G-SIBs and institutions with extensive trade finance or cross-border transaction activities.

Collateral and Balance Sheet Transmission Risk - Tariff shocks subtly recalibrate collateral valuations, currency exposures, and liquidity positions—often before formal metrics reflect the change. Traditional capital and liquidity models tend to underestimate the speed and magnitude with which tariff-driven shifts in commodity or asset prices can erode loan-to-value ratios, compress collateral coverage, and trigger funding or margin stress.

Hidden Correlation and Concentration Risk - Traditional risk frameworks assume diversification remains stable across sectors, but tariff shocks can rapidly synchronize stress across previously uncorrelated industries. Disruptions in trade flows can simultaneously pressure logistics, manufacturing, and consumer credit segments—creating hidden clusters of vulnerability that standard correlation-based models fail to detect.
