How War and Rising Inflation Are Reshaping Business Valuations in the USA and Globally

The global economy has entered one of its most complex periods in modern history. Geopolitical conflicts across Eastern Europe and the Middle East, combined with persistently elevated inflation in the United States, the United Kingdom, the Eurozone, and emerging markets, have fundamentally disrupted how businesses are valued. For finance professionals, valuation analysts, M&A advisors, and CFOs, this is not just macroeconomic background noise — it is a direct variable inside every discounted cash flow model, every purchase price allocation, and every fair value measurement.

This blog explores exactly how war and rising inflation are reshaping business valuations globally, and what valuation professionals must account for in 2025 and 2026.

The Macroeconomic Context: War, Inflation, and Financial Volatility

Inflation in the USA: A Structural Problem, Not a Blip

After decades of low inflation, the United States experienced a dramatic price surge beginning in 2021 that forced the Federal Reserve into one of the most aggressive interest rate hiking cycles in its history. While headline CPI moderated through 2024, core inflation — especially in services, housing, and wages — remained stubborn well into 2025.

For valuation professionals, the implications are immediate:

Higher discount rates — as the risk-free rate (typically U.S. 10-year Treasury yield) rises, the Weighted Average Cost of Capital (WACC) rises, which reduces the present value of future cash flows.
Compressed terminal values — long-duration businesses (technology, biotech, real estate) face the sharpest valuation haircuts in high-rate environments.
Margin compression — higher input costs squeeze EBITDA, which directly reduces enterprise value multiples.

Geopolitical Conflict: The Russia–Ukraine War, Middle East Tensions, and Global Supply Chains

The ongoing war in Ukraine and escalating tensions across the Middle East have created a new layer of geopolitical risk premium that valuation analysts can no longer ignore. These conflicts have:

Disrupted global energy markets, pushing up oil, gas, and electricity costs
Fractured supply chains in metals, agriculture, and semiconductors
Triggered sanctions regimes that affect cross-border transaction valuations
Elevated country risk premiums for businesses with exposure to affected regions

Whether you are conducting a purchase price allocation for an M&A deal or completing a fair value measurement for financial reporting, geopolitical risk is now a required consideration, not an optional footnote.

How Inflation Directly Impacts Business Valuation Methodologies

1. Impact on the Discounted Cash Flow (DCF) Method

The DCF method is the most widely used income-based valuation approach. Inflation affects it through multiple channels:

a) The Discount Rate (WACC)

WACC is the single most sensitive input in a DCF model. When the U.S. Federal Reserve raises the federal funds rate to combat inflation, the risk-free rate rises in parallel. A 200 basis point increase in the risk-free rate can reduce the DCF-derived equity value of a growing tech company by 30–50%.

For clients seeking expert valuation and advanced financial modeling, getting the WACC right in an inflationary environment is arguably the most critical step in the entire exercise.

b) Revenue and Cost Projections

Inflation creates a double-edged problem in cash flow forecasting:

Revenue projections must account for pricing power — can the business pass on cost increases to customers?
Cost projections must reflect rising wages, raw material costs, energy costs, and logistics expenses.

Businesses with limited pricing power and high operating leverage face the most significant valuation risk. Our team at Synpact uses sector-specific inflation sensitivity analysis to stress-test these projections in every engagement.

c) Terminal Value

In a standard Gordon Growth Model terminal value calculation, the terminal growth rate is subtracted from the discount rate. As inflation pushes up both the growth rate assumption and the discount rate, the spread — and therefore the terminal value — can become highly volatile and model-sensitive.

2. Impact on Market-Based Approaches (EV/EBITDA, P/E Multiples)

Comparable company and precedent transaction multiples compress during inflationary periods. Here is why:

Public market investors reprice growth stocks downward as future earnings are worth less in present value terms
M&A deal volumes decline, which reduces the availability of recent comparable transactions
Sector-specific multiples diverge dramatically — commodity-intensive businesses (oil, mining) may see multiple expansion, while rate-sensitive sectors (real estate, SaaS) see multiple compression

For firms conducting comparable company analysis or precedent transaction analysis, it is now essential to normalize historical multiples for the inflationary environment and select only the most time-relevant comparables.

3. Impact on Asset-Based Valuation

Inflation also distorts asset-based valuations:

Physical assets (real estate, machinery, inventory) may appreciate in nominal value but face higher replacement costs
Goodwill and intangible impairment testing becomes more likely as higher discount rates reduce the recoverable amount of cash-generating units
Lease accounting valuations must be recalibrated to reflect current market rent levels, which have risen significantly in many geographies

Geopolitical War and Its Specific Impact on Valuation

Country Risk Premium Adjustments

The Damodaran country risk premium (CRP) framework — widely used by valuation professionals globally — has seen significant upward revisions for countries exposed to active conflict or economic sanctions. Businesses with operations in or supply chains dependent on Russia, Ukraine, Belarus, Iran, and parts of the Middle East now carry materially higher CRPs.

For international valuation engagements — particularly those involving M&A buy-side and sell-side valuations — the appropriate CRP adjustment can be the single largest driver of valuation outcome.

Energy Price Volatility and Sector-Specific Impacts

Wars in energy-producing regions create commodity price shocks that affect different sectors asymmetrically:

Energy companies (oil, gas, LNG): Benefit from higher commodity prices; valuations may increase
Airlines, shipping, manufacturing: Face severe margin pressure from fuel costs; valuations decline
Agriculture and food businesses: Subject to grain and fertilizer price volatility; supply chain disruptions increase execution risk
Technology and semiconductors: Affected by rare earth mineral shortages and sanctions on chip exports

Valuation firms advising clients in these sectors must use scenario-based DCF analysis — building bear, base, and bull cases around commodity price trajectories — rather than single-point estimates.

Impact on M&A Deal Activity and Transaction Valuations

Geopolitical uncertainty reduces M&A transaction volumes. When fewer deals close, the universe of available comparable transactions shrinks, making market approach valuations less reliable. Buyers apply higher risk premiums to cross-border targets. Representations and warranties in deal documentation become more extensive and more costly.

In our deal execution support practice, we are seeing clients request more detailed scenario analyses, more conservative projections, and more robust downside case modeling than at any time in the past decade.

Global Perspective: Inflation and War’s Impact Beyond the USA

United Kingdom

The UK has faced one of the most severe inflation crises in the G7, driven by post-Brexit supply chain disruptions, energy dependency, and a weaker pound. Business valuations in the UK — particularly in retail, hospitality, and real estate — have been materially impacted. Discount rates for UK-based DCF models remain elevated.

Eurozone

Germany, France, and Italy face energy insecurity stemming directly from the Russia–Ukraine conflict. European businesses with heavy energy consumption (steel, chemicals, automotive) have seen significant valuation pressure. The European Central Bank’s rate hike cycle has pushed up European WACC benchmarks across the board.

Emerging Markets

Countries like India, Brazil, Turkey, and Pakistan have faced imported inflation through higher dollar-denominated commodity prices and weaker local currencies. Cross-border transfer pricing and intangibles valuations become more complex when functional currencies are depreciating rapidly.

Australia

Australia, though geographically distant from active conflicts, has experienced significant inflationary pressure driven by housing costs, wage growth, and commodity-linked terms of trade shifts. Purchase price allocation for Australian M&A deals now requires careful attention to RBA rate trajectories and sector-specific multiple compression.

Implications for Financial Reporting Valuations

For companies required to conduct annual goodwill impairment testing under IFRS or US GAAP, the inflationary environment has created a wave of impairment risk:

Higher discount rates reduce the recoverable amount of reporting units
Businesses acquired at peak valuations (2020–2021) are now likely to trigger impairment indicators
Auditors and regulators are scrutinizing impairment analyses more rigorously

Similarly, stock-based compensation valuations and 409A valuations for startups have been significantly affected. The era of peak startup valuations has ended. Companies that received 409A valuations in 2021 at peak multiples now face dramatically different valuations — with tax and compensation implications for option holders.

What Valuation Professionals Must Do Differently in 2025–2026

1. Update Discount Rate Inputs Frequently

In a normal interest rate environment, WACC might remain relatively stable for 12–18 months. In today’s environment, discount rates must be reviewed quarterly, at a minimum. Risk-free rates, equity risk premiums, and beta estimates are all moving targets.

2. Use Scenario-Based Rather Than Single-Point Analysis

Single-point DCF analysis is no longer sufficient. Every valuation engagement should include at minimum a base case, an upside scenario, and a stress-tested downside scenario. For businesses with significant geopolitical exposure, additional scenarios tied to conflict escalation or commodity price shocks may be warranted.

3. Apply Appropriate Country and Sector Risk Premiums

Whether using the CAPM framework or a modified build-up approach, valuation analysts must carefully calibrate risk premiums for the current environment. Generic inputs from pre-2022 databases will produce materially incorrect results.

4. Document Assumptions Thoroughly for Audit Defensibility

Regulatory scrutiny of fair value measurements has increased. Audit committees, independent auditors, and the SEC/FCA/ASIC all expect thorough documentation of key assumptions — especially discount rates, growth rates, and market approach multiples — in an environment where those inputs are unusually uncertain.
