Viewpoint: Strike’s Duration Will Determine Impact on P/C Insurance Industry

The International Longshoremen’s Association (ILA) went on strike on Tuesday, Oct 1. The strike is expected to affect more than 20 ports along the Eastern Seaboard and Gulf Coast, including the ports of New York and New Jersey, Baltimore and Houston.

Focusing specifically on the strike’s impact on the property/casualty industry – and given the specific goods transiting through those ports – the impact will be most direct for homeowners, personal and commercial auto, and commercial property. More specifically, the strike may lead to increased replacement costs and delays in the supply and replacement of homeowners’ content, such as garments and furniture; of European-made vehicles and vehicle replacement parts; and of concrete, especially for commercial construction.

However, the strike’s impact will be significantly mitigated by current inventories for each of the impacted insurable goods and the tightness of related just-in-time supply chains. At minimum, Triple-I estimates, the strike would have to last one to two weeks to trigger further sustained increases in P/C replacement costs or accelerate a current slowdown in P/C underlying growth.

Another way the insurance industry would be affected is from losses from coverage protecting against adverse business costs of events, such as strikes. These coverages include, but are not limited to, business interruption, political risk, credit, supply-chain insurance, and some marine and cargo. However, most such policies have waiting periods ranging from five to 10 days, and then deductibles, before payment is triggered. As a result, losses for those lines are likely to be limited if the strike lasts less than one to two weeks.

Using a one to two-week timeline is helpful: The last major longshoremen’s strike in the United States – at the port of Long Beach, Calif., in 2021 – lasted one week.
