Insurance pricing once moved in lockstep with consumer inflation, but since 2021 that link has broken. Global supply chain shocks, rising repair costs, and nuclear verdicts have pushed motor insurance inflation far beyond CPI, leaving traditional actuarial models outdated. Sustainable coverage now demands forward-looking underwriting that factors in volatility, litigation, and global cost drivers.
History
For decades, inflation and insurance pricing moved largely in sync.
As long as consumer inflation stayed subdued, underwriters could apply straightforward trend assumptions to forecast premiums.
But cracks were visible:
Medical inflation persistently outpaced general price levels.
โSocial inflationโ pushed liability costs upward as courts awarded increasingly generous compensation, especially in the U.S.
These pressures hit lines such as Auto Physical Damage (APD), Auto Liability (AL), and Motor Truck Cargo (MTC).
Still, the long-term pattern was clear: insurance pricing followed the same low, steady trajectory as general inflation.
That alignment broke in summer 2021. Supply chain shocks, geopolitical instability (notably the war in Ukraine), and sharp increases in commodity and wage costs drove inflation higher.
But insurance inflation, especially in commercial motor, rose even faster and far less predictably.

For motor trucking (APD, AL, MTC), the divergence is especially painful. Costs for repairs, replacement parts, used vehicles, litigation, and nuclear verdicts all surged.
Traditional underwriting models failed in two ways:
1๏ธโฃ Flat CPI doesnโt benefit fleets.
When consumer inflation is low or even negative (e.g. March 2025, CPI fell 0.1% MoM), insurers donโt reduce premiums. Years of price stability gave fleets no relief. Premiums stayed sticky.
2๏ธโฃ Trending ignores macro shocks.
Standard actuarial trending misses global disruptions that donโt show up in CPI. Events like the Ukraine war, semiconductor shortages, or supply chain collapses raise claims in ways CPI doesnโt capture.
The result
Fleets face unpredictable, compounding costs. Insurers struggle to balance affordability with sustainability. Unlike household inflation, insurance inflation in motor lines is buffeted by global risks, legal trends, and technological complexity.
Conventional underwriting playbooks are no longer enough. Future resilience in APD, AL, and MTC requires models that factor in global cost drivers, supply chain volatility, and litigation risk.
Insurers that donโt recalibrate will either overcharge in calm times or undercharge in crisis. Needless to stress that both end up eroding trust and long-term viability.
The lesson is clear
Insurance inflation has parted ways from general inflation, and motor trucking sits at the crossroads of this divergence. Sustainable coverage demands a global, forward-looking underwriting lens.
