Economic Signals for Reserving.
Every reserve study embeds an inflation view, whether stated or not. This feed tracks the BLS, CMS, and market data actuaries use to set severity trends, and flags when a release should change your assumptions.

October CPI: Hospital Services Up 0.8%, No 12-Month Trend
BLS published October 2026 CPI on November 10 with hospital services up 0.8% for the month but no 12-month change, because October 2025 was never collected. The reserve question is not the print but which substitute trend replaces the blank column, since the choices land about four points apart on hospital severity.
AIG's $91M Discount Charge Reopens Reserve Discounting Debate
AIG's Q3 2026 release shows a $91M pre-tax net loss reserve discount charge against a $2M benefit a year earlier. The new argument: a discount line can move a booked reserve with no claim changing, so self-insureds should ask for discounted and undiscounted figures side by side before reading any reserve change as a claims signal.
Hanover: Commercial Lines Released Just $3M in Q3 Reserves
Hanover's Core Commercial segment posted a 100.5% combined ratio in Q3 2026 but released only $3.0 million of prior-year reserves, so its benchmark is cat-driven noise, not reserve noise. For a self-insured, the usable carrier number is the current-year ex-catastrophe ratio, and that is a different figure from the headline.
SF Fed: El Niño Raises 2027 Inflation Risk to Reserve Trends
A November 2 San Francisco Fed letter says El Niño could add up to 1 point to 2027 inflation, but only if a La Niña follows. For discounted long-tail reserves, a one-point trend shock needs roughly a 100 basis point rate rise to wash out, so the two effects do not simply cancel.
ECI: Health Benefits Up 6.4% While Wages Rise Just 3.1%
The September 2026 ECI widens the health-versus-wage gap to 3.3 points, and the new argument is arithmetic: a single blended trend hides a mix shift, and on a 53/47 medical-indemnity split the two-trend answer runs about 1.75 points a year above a wage-only trend.
Fed's Hawkish Dissent Tests Your Reserve Discount Rate
The FOMC held at 3.75%-4% on October 28, 2026 as Governor Lisa Cook and Cleveland Fed President Beth Hammack dissented together for a hike, the first governor-president joint hawkish dissent since 1992, while Chair Kevin Warsh confirmed the Fed will cut rate-setting meetings from eight to six starting in 2027, shrinking the number of scheduled checkpoints self-insureds get between formal discount-rate resets.
September PPI Resets Construction Claim Severity Assumptions
Nonresidential construction input costs rose 11.9% year over year in September 2026, the steepest climb in four years, and this time the damage is diesel-led rather than tariff-led. For self-insureds holding open builder's risk, property damage, and completed-operations claims, the repair cost embedded in today's case reserves is moving away from the reserve faster than blended indices suggest.
Marsh Q3 Index: Excess Casualty Jumps 13% as WC Falls 5%
Marsh's Q3 2026 Global Insurance Market Index shows US excess and umbrella casualty rates up 13% while workers' comp rates fell 5%, the widest spread between the two lines this year and the first quarter where the gap stopped narrowing. Falling WC premiums reflect calendar-year profits and carrier competition, not falling loss costs; self-insureds who let soft renewal quotes drive trend selection will underfund the retained layer while excess carriers price a 9.5 to 12% severity trend.
The September FOMC Decision Sets Your Tail Reserve Discount Rate
The FOMC meets September 15-16, 2026 with the funds rate at 3.50% to 3.75% and a June dot plot whose 3.8% median penciled in one more hike. The Summary of Economic Projections due September 16 will anchor discount rates in year-end reserve studies, and the present-value swing is computable now from your own payout pattern: on a level 15-year payout, 50 basis points moves the reserve about 3.6%.
What Three Fed Dissenters Mean for Long-Tail Reserve Discounting
The August 19 FOMC minutes confirm a 9-3 vote and three unified hawkish dissenters, putting a September 15-16 hike fully in play; self-insured programs and captives discounting long-tail reserves need a pre-September check on whether discount rate assumptions reset at year-end and whether captive duration mismatch creates an asymmetric funding exposure.
Everest's $200M Casualty Charge Flags Older-Year Reserve Gaps
Everest Group strengthened North America treaty casualty reserves by roughly $200 million across most accident years in Q2 2026, a signal that prior-year development has not finished for the lines beneath self-insured retention layers.
Q2 Earnings Signal the WC Reserve Cushion Is Thinning
Cincinnati Financial and the Hartford booked casualty reserve charges in Q2 2026 while workers comp releases shrank. The favorable WC development that has masked casualty deficiency is a depleting asset, and self-insureds hold the same asset.
Friday's ECI Sets WC Wage and Health Trend Anchors
The BLS releases the Q2 2026 Employment Cost Index on July 31, one of the cleanest single reads on two reserve inputs at once: wage growth that drives workers' comp indemnity escalation and employer health cost that sets self-funded plan trend.
Marsh: US Casualty the Lone Rising Line as Rates Fall
Marsh's Q2 2026 index shows global commercial rates down 6% and property down 12%, while US casualty rose 7%. For buyers who retain the risk, that divergence is a severity signal to fund in the reserve, not a premium quote.
Fed's July Meeting Tests Long-Tail Reserve Discount Rates
The FOMC meets July 28-29 with the funds rate at 3.50% to 3.75% and nearly half of policymakers open to a hike. The cut-driven decline in discount rates many 2026 reserve models penciled in never arrived, and that reprices long-tail present values.
June Import Prices Flag Medical Equipment Severity
Overall import prices rose 7.1% in the year to June 2026, the fastest since 2022, and scientific and medical machinery led the capital-goods gain. The line that feeds medical severity is still climbing while headline goods inflation looks calm.
June PPI Splits: Goods Deflate While WC Medical Holds
The June 2026 PPI fell 0.3% as goods dropped 1.4% and energy deflated, yet producer services held at 4.6% and inpatient care rose. A single blended medical trend now misstates at least one line in a self-insured program.
May PPI Puts Fleet Repair and WC Medical Trend on Notice
The BLS May 2026 Producer Price Index release put current numbers on goods, fuel, transportation, and material inflation. For self-insured claim programs, the reserve issue is paid severity rising before open claim case reserves fully catch up.
Q1 Carrier Earnings Flash Warning for Excess Casualty Buyers
CNA's $106 million adverse reserve development in excess casualty and Ryan Specialty's 'canary in the coalmine' warning signal that self-insured programs sharing the same accident years should stress-test their own retained-layer picks.
May CPI Hits Three-Year High at 4.2% as Energy Costs Spike
The BLS May 2026 CPI at 4.2% year over year, driven by energy, creates a 130-basis-point gap with core CPI that forces line-specific inflation assumptions for self-insured WC, auto, and GL severity trends.
Headline CPI at 3.8% Moves Discount Rates While Medical Cools
April's CPI print widened the gap between headline inflation at 3.8% and medical care CPI at 2.5%, pulling long-tail discount rates and severity assumptions in opposite directions for self-insured reserves.
GL and Commercial Auto Remain Above 100% CR Through 2026
The Triple-I/Milliman May 2026 outlook shows the P/C industry hit a decade-low combined ratio, but GL and commercial auto remain above 100, signaling that self-insured loss picks for those lines need upward revision.
April PPI: Construction Input Costs Surge 6.6% on Tariffs
The BLS Producer Price Index for nonresidential construction inputs rose 6.6% year over year in April 2026, with tariff-exposed metals leading the spike and pressuring claim severity for GL construction defect, public entity property damage, and WC construction classes.
April CPI Is the First Real Test of Tariff-Driven Severity
Tomorrow's BLS release is the first to capture tariff pass-through from the April 2 implementation, and the medical care, hospital services, and auto repair sub-indices will tell self-insured employers whether current severity trend picks are already stale.
Marsh: US Excess Casualty Rates Jumped 18% in First Quarter
Marsh's Q1 2026 Global Insurance Market Index shows US casualty as a global outlier at +9%, with excess and umbrella rates up 18%, signaling severity pressure that self-insureds should benchmark against their own retention-layer trend picks.
Fed's 'Elevated' Inflation Call Clouds Long-Tail Reserve Math
The FOMC's April 29 upgrade from 'somewhat elevated' to 'elevated' inflation, paired with four dissents on the rate path, creates competing pressures in discount-rate and severity-trend selections for self-insured long-tail programs.
ECI: Employer Health Insurance Up 5.7%, Wages Up 3.4% in Q1
The widening gap between benefit cost growth and wage growth compresses self-insured funding margins and signals that WC indemnity severity assumptions anchored to prior-year wage data may already be stale.
Hospital Services Inflation Hits 6.4% in March CPI Release
The BLS hospital services sub-index is running nearly double headline inflation, putting medical severity trend assumptions under pressure for workers' comp, health plan, and hospital professional liability reserves.
Why Self-Insureds Should Ask for an Independent Reserve Review
Your TPA's actuary is not your actuary. Here is the structural reason that matters, and what an independent review actually buys you.
The Reserve Cycle Is Quieter Than the Underwriting Cycle, and Twice as Expensive
