The Bank for International Settlements published a Bulletin finding that disruptions at critical supply chain chokepoints cause greater output losses and price pressures than comparable shocks at less central nodes. A one standard deviation increase in disruptions at key country and sector nodes is associated with a 50% larger decline in global industrial production growth and raises downstream producer prices by about 70 basis points within one year. Substitution and inventories can limit production losses, but alternative inputs often cost more and buffers become less effective as they are depleted. The Bulletin concludes that monetary policy should generally look through first round inflation effects while expectations remain anchored and second round risks are low. Policy calibration should reflect the disruption’s cause, supply chain centrality, availability of substitutes, inventory and capacity buffers, margins and demand conditions. Targeted fiscal measures such as credit guarantees may support supply repair without stimulating demand, while subsidies that cushion price increases may weaken incentives to substitute. The continued drawdown of oil reserves during disruption around the Strait of Hormuz has increased the risk of sharper, nonlinear inflation effects.
Bank for International Settlements finds chokepoint disruptions intensify output losses and price pressures
The Bank for International Settlements finds that supply chain chokepoint disruptions produce larger output losses and stronger price pressures than shocks at less central nodes. Substitution and inventories can protect output but may raise input costs, requiring policy responses calibrated to supply chain centrality, available buffers, demand and second round inflation risks.
