News Analysis: potential outstanding effects from the Iran war and oil shock - Annual Report

Live News

The Iran conflict has severely disrupted global oil supply, with the Strait of Hormuz—a passage through which approximately 20% of the world's oil flows—effectively blocked to tankers and cargo ships. This geopolitical crisis has generated the most significant oil supply shock in recorded history, prompting the International Energy Agency to issue stark warnings about spreading demand destruction as scarcity and elevated prices persist. Fast-rising gasoline prices have eroded American household finances, compounded by slowing wage growth and declining consumer sentiment. The economic toll has been unevenly distributed, falling disproportionately on lower-income households with limited financial flexibility. Economists from RSM US, including chief economist Joe Brusuelas and colleague Tuan Nguyen, have mapped potential outcomes using historical oil shock data, identifying cascading effects through reduced consumer spending, diminished business investment, and potential layoffs. Recent developments offer cautious optimism. Nancy Vanden Houten, lead US economist at Oxford Economics, notes that oil prices have retreated from peaks and the ceasefire has introduced a degree of stabilization. American consumers, supported by enhanced tax refunds and resilient asset portfolios, have demonstrated unexpected adaptability. However, Vanden Houten cautions that conditions could deteriorate rapidly depending on conflict trajectory and maritime access restoration.

Key Highlights

The Strait of Hormuz remains the critical vulnerability point in global energy markets. With roughly one-fifth of worldwide oil shipments transiting this waterway, extended closure would perpetuate supply constraints and maintain upward pressure on energy prices across the economic spectrum. Consumer behavior modifications are already evident. Households are reducing discretionary spending on dining, travel, and major purchases. Bryan, a 30-year-old automotive industry engineer, exemplifies the adaptive response: he has reduced driving, transitioned to remote work where possible, redirected emergency funds to Treasury securities, and shifted grocery purchasing to wholesale outlets. His planned kitchen renovation and vehicle purchase have been postponed indefinitely. The food supply chain faces mounting pressure from multiple vectors. Diesel fuel costs—elevated by the oil shock—increase transportation and agricultural operating expenses. Simultaneously, nitrogen-based fertilizer supplies face disruption, potentially influencing planting decisions and autumn harvest availability. Food economists estimate that full consumer price impacts may require six months or longer to materialize fully. Income stratification determines resilience. Lower-income households in the bottom two economic quintiles lack emergency savings buffers and face the most severe demand destruction effects. Sian, a 59-year-old Phoenix resident, illustrates this vulnerability: she must drive to multiple jobs across the sprawling metropolitan area, has ceased retirement contributions, reduced grocery spending, and canceled medical appointments to manage transportation costs.

Expert Insights

The concept of demand destruction, while linguistically stark, accurately describes the economic phenomenon at play. When price shocks achieve sufficient magnitude, persistence, and pain threshold, spending behaviors undergo fundamental shifts that may permanently alter sector structures and economic trajectories. The current situation presents precisely these characteristics. Joe Brusuelas emphasizes the temporal dimension: "Time is not the ally of the American economy." His analysis identifies differential impacts across industries, income cohorts, and household types. The US economy contains over one billion distinct prices, meaning demand destruction will manifest unevenly rather than uniformly. Energy costs permeate every economic transaction, from household heating and transportation to industrial production and freight logistics. Historical precedent offers both warning and guidance. The 1970s energy crisis produced lasting structural changes in American consumption patterns, manufacturing efficiency, and automotive design. Brusuelas references the more recent supply chain disruptions of early 2020, noting that inflation did not materialize until 2021—over a year after initial shocks. Similarly, tariff pass-through effects continued into 2025. These examples demonstrate that economic consequences of supply disruptions often exhibit delayed manifestation, complicating policy response and market forecasting. The recovery timeline defies optimistic assumptions. "Turning off the oil and turning it back on is not like turning on your lights," Brusuelas observes. Even with immediate conflict resolution, meaningful production restoration across the Persian Gulf would require at minimum six months. Full recovery in some sectors could extend over years, depending on infrastructure damage, workforce availability, and investment levels. Vanden Houten's assessment introduces crucial nuance. The economic outlook has improved relative to initial conflict assessments, with oil prices retreating from crisis peaks and ceasefire developments providing stabilization. Consumers have demonstrated resilience, supported by tax refunds and appreciation in stock and real estate holdings. This combination suggests the worst-case scenario—widespread demand destruction cascades—remains avoidable. However, this optimism carries significant conditionality. The trajectory depends entirely on conflict resolution speed and restoration of maritime commerce through the Strait of Hormuz. The interconnected nature of modern supply chains means that fertilizer, chemical, and agricultural disruptions can propagate through the economy in ways not immediately visible in headline energy prices. The diesel powering agricultural equipment ultimately determines grocery shelf prices, and nitrogen-based fertilizer availability influences planting decisions with harvest-time consequences. The human dimension of this economic stress test reveals troubling patterns. Lower-income households face impossible tradeoffs: Sian must drive despite prohibitive costs because alternative transportation infrastructure does not exist in her region. Will drives for Uber while managing childcare expenses, unable to absorb unexpected financial shocks without depleting retirement savings. These individual circumstances aggregate into macroeconomic vulnerability, as reduced consumer spending dampens business revenues, potentially triggering layoffs that further compress consumer spending. The emerging "new normal" represents a permanent downgrade in living standards for many households. As one industry professional noted, referencing family members who lived through the 1970s energy crisis, "The best you can hope for is to keep up, and nobody ever quite keeps up." This sentiment captures the structural challenge: even if energy prices stabilize, the behavioral adaptations and consumption patterns that emerged during the crisis may persist, permanently reducing aggregate demand and economic dynamism. Market participants should monitor several indicators for signs of stabilization or deterioration. These include: Strait of Hormuz shipping traffic data, gasoline price trajectories, consumer confidence indices, retail sales figures for discretionary categories, food price inflation readings, and employment trends in lower-income sectors. The six-month recovery timeline suggested by economists provides a framework for assessing progress, while acknowledging that historical precedent allows for considerably longer adjustment periods depending on geopolitical developments and structural supply chain damage.
