BIS: disruption at key trade nodes cuts output growth 50% more
The Bank for International Settlements puts short-run GDP losses at about 1% in most countries and up to 4% in electronics-reliant economies under a stress scenario.
- Key trade-node disruptions are tied to a 50% larger fall in global industrial production growth, the BIS said on Oct. 15, 2026.
- Downstream firms' producer prices rise by about 70 basis points within one year of a key-node disruption, according to the BIS bulletin.
- The OECD's June 3, 2026 outlook put the fall in global oil supply between February and April 2026 at 12%.

The Bank for International Settlements published Bulletin No 138 on Oct. 15, 2026: disruptions at key trade nodes are associated with a 50% larger fall in global industrial production growth than hits to less critical nodes.
Key-node disruptions weigh on output and prices
According to the BIS, a one standard deviation disruption at key nodes is associated with a 50% larger decline in global industrial production growth. The authors classified disruptions that firms disclosed on earnings calls with automated text analysis.
Within one year, disruptions at key nodes also raise downstream firms' producer prices by about 70 basis points, the bulletin said. The estimates rest on industry-level producer price responses to the same one standard deviation shock.
A stress scenario puts short-run GDP losses at 1% to 4%
In a simulation where trade costs for high-tech electronics rise 150%, short-run GDP losses are about 1% in most countries and as high as 4% for economies heavily reliant on those sectors, according to the BIS.
Long-run losses average about 0.3% and reach at most 1% in the most exposed economies. The scenario is hypothetical and uses the 2022 input-output table; it is not an observed event.
The bulletin also cites a past case. Japan cut the share of its rare earth imports from China from around 80% to about 45% between 2012 and 2014, but purchases from other countries were much more expensive, the BIS said.
Other trackers describe the Strait of Hormuz shock in similar terms
The OECD Economic Outlook, published June 3, 2026, said global oil supply fell by 12% between February and April 2026. It projects global trade growth moderating from 5.0% in 2025 to 3.1% in 2026.
That is a drop of 1.9 percentage points (our calculation). In a prolonged-disruption scenario the OECD sees global growth of 2.1% in 2026, against 2.8% in its time-limited scenario.
The BIS Annual Economic Report 2026 said the crude oil supply cut exceeded 10 million barrels a day, about 13% of normal supply.
Brent rose 67% to an intraday peak of $120 in under two weeks, according to the report.
The two supply figures differ because they cover different periods and measures. BIS Working Paper 1378, published Sept. 17, 2026, found that effects of Hormuz traffic shocks start after four to six months and can last up to a year.
For scale, an Oxford University study of maritime chokepoints estimates losses from delays, rerouting, insurance and trade disruption at $10.7 billion per year, plus $3.4 billion in freight costs. The page shows no publication date, so the comparison is indicative.

What the data does not show
The bulletin has no separate limitations section. The authors say realised impacts depend on the product, substitution, inventories and margins, so the headline effects are averages, not forecasts for any one company or country.
Our reading: the results rely on text analysis of earnings calls, which cover only firms that hold them, and the GDP figures come from an assumed 150% cost shock rather than a measured one.
How we reported this: we opened every linked page on Oct. 20, 2026. The 1.9-point figure is our calculation (5.0 - 3.1). We left out IMF outlook figures because the IMF page did not open.
