Cut a supplier

Pick a stage of one of the ten chains and an exporter, and cut its exports: who loses what share of their supply, who could fill the gap, and what passes one stage down the chain. First-round arithmetic on 2024 trade shares, not a forecast.

Lithium-ion batteries and electric cars · S3 · Anode graphite (artificial)

Cut the exports of China in Anode graphite (artificial) (Lithium-ion batteries and electric cars, stage 3) and follow the shortfall to the importers and one stage down the chain.

Lithium-ion cells and packs

7.5% of world lithium-ion cells and packs exports at risk in the first round, summed over the 22 large exporters with an exposure upstream. The 8 listed below carry 6.9%.

An exporter of the next stage loses its share of world exports × its own exposure upstream (× the use share). Exporters on a closed route lose their own exports × the cut. Exposure upstream is the share of its imported anode graphite that came from the closed supplier, not of all the anode graphite it uses: where most are made at home (Japan, Korea, Germany for car parts), it overstates the risk.

First-round arithmetic on trade shares, not a forecast: an importer’s exposure is its import share from the shocked suppliers × the cut. No stocks, no new suppliers, no price changes.

Suppliers are read from the flows the map stores for the stage: each importer’s ten largest suppliers and every flow above 0.05% of world trade; the rest are “smaller suppliers”. The next stage and the use share come from the chain file.
