Robert Hartwig, Clinical Associate Professor of Finance & Insurance, and former President of the Insurance Information Institute, recently posted on Linkedin his strongly negative views on President Trump's tariffs. In his post, he stated that import taxes (i.e., tariffs) will “unquestionably raise claim severities across all auto and property lines”. He also noted that insurers must "be vigilant in monitoring underlying claim severity trends and incorporate them into ratemaking as quickly as possible, to avoid falling behind, as happened with inflation after the pandemic."
While it seems clear that auto and homeowners insurance will likely increase as a result of the implementation of tariffs due to their expected inflationary impact on auto parts and construction materials, it is less clear at this point as to how tariffs will impact the professional liability insurance market. In our discussions with various insurance executives, Architects and Engineers was the only major line of professional liability business that was identified to have an impact, again mostly due to the increased costs of construction might have on future A&E claims costs.
That being said, to the extent that tariffs increase inflation generally, those increased costs over time will tend to ripple through the economy in the form of increased salaries due to costs of living adjustments. To the extent that law firms defending insureds in professional liability claims increase their hourly rates in response, there would likely be increased upward pressure on rates that would likely be seen in a few years after the implementation of the tariffs.
In his LinkedIn post, Hartwig also stated that financially, with the S&P 500 teetering on the edge of an official bear market (20% decline), P&C insurers could face an unrealized loss on their equity holdings approaching $200 billion. Moreover, recession fears and the expectation that the Fed will soon need to cut rates which would push interest rates down, would also cut into insurer investment income.
In a medium to long tail lines of business such as professional liability, to the extent that insurers are earning less investment income on their portfolios, it could also force them to raise rates to make up the difference. However, the magnitude of such effects are still subject to much speculation at this point, as the final form of the tariffs seem to have a long way to go before they are etched in stone.
