sticky inflation creates a bifurcated economic landscape

Take a moment to read the latest headlines hitting the “wires”:

“Producer prices surged more than expected in July, spurring inflation concerns” – 08/14/25 Fox News

“Hot PPI inflation cools big Fed rate-cut hopes; S&P 500 falls” – 08/14/25 Investor’s Business Daily

“CPI Report: Core inflation rises by most in six months, stoking tariff-driven prices concerns” – 08/12/25 Yahoo Finance

“U.S. inflation report shows effects of Trump’s tariffs” – 08/12/25 The New York Times

And hundreds more inflation articles have been swirling in just the past week as new numbers come out. But the same basic premise repeats: The 2025 global economy continues to grapple with persistent inflationary pressures that have defied initial expectations of a swift return to pre-pandemic norms. Inflation remains stubbornly above target levels, presenting ongoing challenges for policymakers, businesses, and consumers alike.

The roots of this persistent inflation can be traced back to the COVID-19 pandemic, which triggered a series of supply and demand shocks. The Federal Reserve has been actively trying to correct inflation since early 2022, when inflation spiked to its highest levels seen since the 1980s. During this peak, the CPI reached 9.1% percent for the 12 months ending June 2022. It has since come off that high, but inflation is still rising and some economists fear a reacceleration.  Why?

Companies along the supply chain are still in the process of recouping the massive cost inflation experienced post-COVID.   Now add in:

  • Tariffs: The implementation of tariffs is likely to have an inflationary impact in most cases, although some products may see only minor price increases due to substitution effects. Some companies had been “eating” the costs, but that can only last so long before a margin squeeze.
 
  • Onshoring and Supply Chain Duplication: The trend towards reshoring and diversifying supply chains is increasing demand for materials to construct warehouses and industrial facilities, adding to inflationary pressures.
 
  • Labor Market Dynamics: Wage pressures and labor shortages in certain sectors continue to drive up costs. Restrictions on immigration could contribute to labor shortages and lead to inflation in services.
 

Economists’ concerns seem valid, as corrective actions by the Federal Reserve have done little to tame inflation – hence the “sticky” moniker.  The Reserve Federal Bank of Atlanta even instituted a Sticky Price CPI (SP CPI) to assess whether volatile, short-term factors (latest headlines and geopolitical posturing) are driving increases or more persistent price stickiness is the cause. In essence, the SP CPI takes into account rent, insurance, medical care, certain utilities and the like while excluding more volatile items that can skew regular inflation measurements like fresh food, energy or gasoline prices. And those metrics don’t look promising.  The SP CPI rose 4.6% (on an annualized basis) in July, following a 4.3% increase in June.   And less than a week ago (on August 14th), the Producer Price Index (PPI) for July posted an unwelcome surprise, with “core” producer prices (excluding food/energy/trade services – for a fair apples to apples comparison) up 0.6%, the most since March 2022.

STICKY INFLATION: NOT JUST A U.S. PROBLEM 

The issue of “sticky inflation” is not a singularly U.S. problem.  In the U.K., inflation hit hotter-than-expected 3.6% in June, above May numbers; June “core” inflation rose to an annual 3.7%, up from 3.5% for the twelve months to May.  In Japan, the main driver of inflation is rice prices, which doubled in price in May (the largest increase in more than half a century), mainly due to poor harvests in 2023/2024.  Yet the Bank of Japan has been reluctant to hike rates to combat inflation that has run above target since October 2022. 

However, the Eurozone has seen consumer prices come down (2.2% in April to 1.9% in May), marking the first time since September 2024 that headline inflation has fallen below the ECB’s 2% target and made a further rate cut in June.  But picking apart the Eurozone by country shows a different story: Spain, France and Italy posted higher-than-consensus core inflation, while Germany was relatively stable from June to JulyOnly in China do most projections point to low CPI inflation and PPI deflation for the rest of 2025.  So how does this play out for global companies?

Sticky inflation creates a bifurcated economic landscape, not only by country, but also by sector: some face demand destruction and pricing pressure while others — particularly those with market concentration or serving essential needs — are able to sustain higher prices, pass those along to the consumer and/or maintain demand despite reduced consumer purchasing power. 

WINNERS AND LOSERS IN A STICKY SITUATION

Without going into detail on every sector in the MSCI World Index, here is a quick breakdown of a few potential winners and losers facing a “sticky situation”:

Consumer Staples:  People need food, beverages and household goods – items that you simply “can’t live without” and will pay up for it.  Consumers may get pickier at the supermarket, choosing off-brand alternatives or substituting pricey beef for cheaper chicken. But typically, consumers stick with what they know.  Consumer staples companies that tread carefully can end up as the big winners – raising prices gradually without huge demand loss, but doing so on pace with cost increases to avoid the margin squeeze. 

U.S.-based Tyson Foods is seeing this shift firsthand with healthy demand for chicken. For a while there was a big push for alternative proteins like Beyond Meat (not a Polaris holding) and similar, however we continue to believe chicken is a cost effective way for people to consume protein.  Dutch coffee/tea purveyor JDE Peet’s has performed well, as people won’t forgo their morning caffeine fix despite higher prices.  Other more discretionary food items like chocolate (Switzerland’s Barry Callebaut) haven’t fared as well.

Health Care: Health care costs have continued to rise post COVID-19 on the back of labor shortages, drug cost inflation, complex cancer treatments and the like.  To offset these expenses, health insurance providers are repricing premiums – which in turn creates its own inflationary spiral that feeds into overall CPI calculations and contributes to persistent inflation pressures.  

It is a tough operating environment for health insurers in the U.S.  UnitedHealth Group announced premium increases throughout 2025, while cost containment pressures drive them to seek innovative contracting models with hospitals and pharmaceutical firms. CVS Health Corp., through its insurance arm Aetna and national pharmacy network, has also navigated mounting cost and demand pressures by expanding access to generic drugs and integrated care services, seeking to offset upward cost trends for consumers. As two of the largest U.S. players, their operational responses and pricing strategies play a critical role in shaping insurance costs and healthcare inflation throughout the broader economy.

Conversely, pharmaceutical companies have seamlessly navigated – raising drug prices on hundreds of brand-name and orphan drugs, outpacing inflation.  Pharma companies contend that such upcharges are necessary to keep pace with inflation, but also to reinvest cash flows back into R&D to build out pipelines of life-saving drugs.  Adding in tariffs on medicine produced outside of the U.S. only increases the outlook for sticky inflation. Look at French pharma Sanofi, with its fleet of asthma, COPD and myeloma and prostate cancer protocols, or consider Ireland-based Jazz Pharmaceuticals’ Xyrem for narcolepsy and idiopathic hypersomnia. 

Consumer Discretionary: In the simplest of terms: higher prices squeeze consumers, reducing non-essential spending.  Let’s take this in a microcosm: Used vehicle prices surged during COVID-19 due to supply chain disruptions and semiconductor shortages within new vehicle production, while new vehicle costs also climbed sharply due to increased labor negotiations as well as inflationary pressures on the commodity cost side.

This price inflation extended beyond the vehicles themselves—auto repair costs have risen substantially as replacement parts became more expensive, with 60% of parts being imported and now subject to tariffs. Motor vehicle insurance rates have increased dramatically, rising 5.3% annually as of July 2025, driven by higher vehicle values, more expensive repairs, and climate-related claims. This creates a vicious cycle: as repair costs and insurance premiums climb, many consumers choose not to repair their vehicles as it is just too expensive. There are also an increased number of total loss vehicles as the total cost to repair a damaged vehicle exceeds its estimated value, and therefore insurance companies are more likely to declare “total losses”. 

Companies like U.S-based LKQ Corporation, which specializes in recycled and aftermarket auto parts, benefit from this trend as cost-conscious consumers seek alternatives to expensive OEM parts; however since people are repairing their cars less they are experiencing a cyclical downturn.

Utilities: As regulated monopolies, most utilities can’t freely pass increased costs on to its customers due to the “regulatory compact”. And even if they could, regulatory agencies may resist substantial rate hikes, especially during periods when inflation is already squeezing consumers. This constraint can compress margins and slow earnings growth.  Further compounding the pain: utilities are capital-intensive and often carry large amounts of debt to fund infrastructure projects. When rates rise, refinancing and new borrowing costs increase, directly pressuring earnings.  

However, utility demand will not abate as electricity is a basic need in homes and offices.  In fact, demand should ramp up with the added AI/data center needs from hyperscalers.  And when service contracts are up, utilities will renegotiate rates to include inflationary costs.

STUCK IN A RUT: THE LAST MILE OF THE INFLATION FIGHT

While the acute inflationary spike of the post-pandemic period has subsided, the economy appears to be settling into a phase of “higher-for-longer” inflation. Federal Reserve policy is cautious, as tariffs and supply/demand imbalances fuel upward price pressures, while slow labor market normalization reinforces wage growth. The balancing act is compounded by current government spending and deficit levels, along with geopolitical turmoil that can upend European energy prices and supply chains. This complex interplay of factors suggests that the path back to the Federal Reserve’s 2% inflation target may be longer and more winding than initially anticipated.

Companies will need to navigate higher input costs and potential wage pressures, while investors may need to adjust their strategies to account for a prolonged period of above-target inflation. As we continue to monitor these trends, it’s clear that adaptability and careful analysis will be key to successfully navigating the evolving economic landscape of 2025 and beyond.
