The Impact of Rising Interest Rates on Corporate Finance

When the Federal Reserve kicked off its aggressive rate-hiking cycle in 2022, few corporate treasurers thought elevated borrowing costs would still be reshaping capital structures four years on. Yet here we are in 2026, and interest rates are still driving decisions across boardrooms and deal tables — compressing valuations, upending acquisition financing strategies, and forcing companies to fundamentally rethink how they deploy capital. The evidence shows up in the year's most consequential transactions: a record-shattering leveraged buyout of Electronic Arts, BlackRock's ambitious push into regulated utilities alongside EQT and the Qatar Investment Authority.

The Cost of Capital Has Changed the Deal Architecture

Private equity dealmaking has shifted structurally. When benchmark rates sat near zero, sponsors could pile on debt with relative impunity — cash flows would service the obligations comfortably enough. That calculus is far messier today. The $55 billion acquisition of Electronic Arts, the largest leveraged buyout on record, illustrates both the ambition that still runs through this market and the sophistication now required to make the numbers actually work. Sponsors and sovereign wealth backers had to engineer financing structures that account for a meaningfully higher debt service burden, leaning harder on equity contributions and patient, long-duration capital than any prior cycle demanded.

Sycamore Partners' $23.7 billion take-private of Walgreens Boots Alliance tells the same story. Walgreens was already fighting serious operational headwinds before the deal. Add a rate environment where interest payments consume a larger slice of free cash flow, and restructuring that business becomes considerably harder. Sponsors pursuing transactions like this one must now underwrite more conservative revenue trajectories and price in refinancing risk across longer holding periods. Financial engineering hasn't disappeared as a value driver — but it's been substantially boxed in.

Infrastructure and Hard Assets Emerge as Rate-Resilient Havens

In a higher rate environment, capital chases assets with contractual, inflation-linked cash flows. That dynamic explains a lot of what's flooding into infrastructure and real assets right now. BlackRock and EQT's $10.7 billion acquisition of AES Corporation — backed by CalPERS and the Qatar Investment Authority — is a clean expression of that logic. Regulated utilities carry predictable revenue streams anchored to government-approved tariffs, which makes them structurally better equipped to absorb elevated financing costs than cyclical businesses tied to consumer discretionary demand.

If completed, the AES deal would more than double BlackRock's fossil fuel power plant portfolio to over 50 facilities across 11 countries. That's a striking commitment at a moment when energy security concerns are competing loudly with decarbonisation mandates. The transaction reflects a broader institutional conviction: regulated infrastructure — even carbon-intensive infrastructure — offers a defensible spread over risk-free rates that justifies the complexity. For corporate finance professionals, the takeaway is straightforward. Businesses sitting on long-duration contracted assets are commanding acquisition premiums that earnings multiples alone simply don't explain.

AI Infrastructure Defies Rate Gravity

One sector has shown outright immunity to rate-driven caution: artificial intelligence infrastructure. The approximately $40 billion acquisition of Aligned Data Centers by a consortium including BlackRock, Nvidia, and Microsoft — with $30 billion of equity capital committed upfront — makes clear that when strategic necessity is acute enough, the cost of capital becomes almost secondary to the cost of falling behind. Global AI power demand is expanding faster than existing infrastructure can handle, and the companies best positioned to win the next decade of computing are buying certainty of supply now, whatever it costs.

The numbers tell a complicated story about what this creates downstream. AI-adjacent businesses are accessing capital on terms that recall the low-rate era, partly because strategic investors are effectively subsidising returns through the implied value of ecosystem control. Meanwhile, companies in more mature sectors face a genuinely tighter market. The spread between what a data centre developer and a retail conglomerate pay for debt financing has rarely been wider. That divergence is actively reshaping which industries attract deal flow — and which are left managing their balance sheets alone.

Deal Volume Moderates, But Selective Intensity Rises

Aggregate private equity deal activity in Q1 2026 came in at $172 billion across 110 transactions — a 12% decline by value from the $195 billion recorded in Q1 2025. On its face, that looks like a cooling market. Dig beneath the headline and the picture changes. Over the trailing twelve months, firms announced more than $900 billion in deals, a 34% increase over the prior comparable period. What's shifting isn't appetite — it's selectivity. Sponsors are concentrating firepower on fewer, higher-conviction positions rather than spreading capital across a broad pipeline.

Geopolitical uncertainty and AI-driven disruption in software have introduced new variables into underwriting assumptions, particularly across the technology sector. The TikTok restructuring — which saw Silver Lake and Alpha Wave Partners take significant stakes in a newly created US entity while ByteDance retained a minority position — is a good example of the kind of transaction that demands more than financial engineering. It required regulatory and diplomatic maneuvering that most deal teams simply aren't built for. These transactions are harder. They also carry the potential for returns that bear little relationship to conventional market cycles.

Forward Implications: Discipline, Duration, and the Refinancing Wall

Corporate finance teams heading into the second half of 2026 face pressures that look increasingly structural rather than cyclical. The refinancing wall — the volume of corporate debt originated during the near-zero rate era now approaching maturity — is concentrating minds. Companies that aggressively extended maturities in 2020 and 2021 are approaching the reckoning. Those without sufficient cash generation to service refinanced obligations at current rates will face hard choices: equity issuance, asset sales, or covenant renegotiation. None of those options are painless.

For investors, the premium will increasingly attach to businesses with strong free cash flow conversion, low capital intensity, and pricing power sufficient to absorb financing cost inflation. For dealmakers, the lesson from the Electronic Arts LBO and the Aligned Data Centers acquisition is that transformational transactions remain achievable — but they require either extraordinary strategic rationale, patient equity from sovereign and institutional partners, or ideally both. The era of effortless leverage is over. What replaced it is a more disciplined, more rigorous approach to corporate capital allocation — one that will expose, fairly brutally, the difference between genuinely skilled practitioners and those who spent a decade mistaking cheap money for expertise.
