The End of the Beginning: US Tariffs and Private Markets Post-August 1

August 4, 2025 | 7 min read

“Every race is a question, and I never know until the last yards what the answer will be.”

Steve Prefontaine

There is a reason mile markers are placed along the course of a marathon. For runners, knowing they still have 20 miles to go, no matter how daunting that may be, is better than guessing. It allows them to make decisions: slow down, speed up, evaluate how much they have left in the tank. For investors, too, any degree of certainty, any morsel of knowledge, is an advantage. This is why we can mark August 1, 2025, as a key milestone worthy of consideration.

With tariff deals continuing to be made, country-by-country and sector-by-sector, private markets investors are increasingly able to take stock of what is known and think about what could lie around the corner — however far down the road that may be. As we said in April, unknowns persist and the likelihood of a surprise or two along the way is high. So, we may need to adjust our pace once we reach the top of the next hill. Either way, answers to these questions can help formulate a better-informed plan of attack from our current position.

Are markets simply choosing to ignore the tariffs or are they essentially being priced in?

Volatility initially followed the April 2 US tariff announcements, with nearly half of institutional investors making tactical portfolio changes in response and many reallocating away from US equities. However, markets rebounded after the Trump Administration announced a tariff pause that was eventually extended to August 1. Moving into H2, sentiment in the US very recently moved from cautiously optimistic due to resilience in AI-related sectors and mega-cap tech to more solidly mixed. Concerns over jobs data, the possibility for continued inflation, and higher for longer interest rates in the second half of the year are variables the market is focusing on. In Europe and Asia, sentiment is more upbeat with growing confidence from investors that cycles are resetting.

Overall, the tariff and policy environment are not being ignored, they are being priced in gradually and unevenly. Markets are digesting them in stages by reacting to new information and adjusting expectations accordingly. This should continue as negotiations are ongoing, importantly for large economies like China and India whose deadlines have been pushed past August 1. Even agreements for countries whose deals have been announced are not final until they are signed and implemented. Given the tactical approach of the US administration and some disagreement over what has been agreed to, it is likely final arrangements will differ from the current state.

Looking forward, many expect a persistent drag on growth, especially in the US. Corporate profit margins are historically high, allowing companies to absorb some tariff cost pressures and cushioning the blow for markets. However, it will weigh on sentiment and earnings over time and trimming margins does have a limit where, once passed, costs will be passed on to the consumer. We should expect Trump will pay close attention to consumer pricing increases as he does not want to anger his base.

Markets should avoid a sharp correction due to US tariffs, though we did experience a blip on August 1 coming off of higher-than-expected inflation and a revised US jobs report. Where that issue lands after the firing of the Commissioner of Labor Statistics is to be determined and, perhaps more importantly, the debate over whether and when Trump dismisses the Fed Chair looms. The consensus is that Powell will make it through September, but nothing is guaranteed. While the situation isn’t apocalyptic, it’s also far from benign. The US administration’s sectoral and incremental approach has helped avoid worst-case outcomes so far, but the path forward remains uncertain, and further volatility is possible.

How has the tariff dynamic impacted private markets since April 2? What will their impact be post-August 1?

Despite elevated volatility since April 2, private markets showed incredible resilience in the first half of 2025. Global deal count and deal value continued to grow, outpacing the lulls experienced in recent years. However, the exuberance at the beginning of the year was dampened by the uncertainty across the global stage with a slow-down in deal activity across all regions in Q2 following the positive path set in Q1.

Though tariff-induced anxiety did cause stakeholders to wait for market clarity, H1 2025 exits (~$492 billion) have outpaced H1 2024 (~$387 billion). M&A activity remained resilient with total deal value reaching $2.0 trillion across 24,793 deals, a year-over-year increase of 13.6% for deal value and 16.2% for the number of transactions. Q2 did feel the tariff strain, with global deal value down 4.7% from Q1.1 That said, dealmakers forged ahead with US activity characterized by larger deals like Global Payments’ $24.3 billion acquisition of Worldpay2 and Europe buoyed by strong deal count.3

As global markets continue to absorb uncertainty from ongoing tariff negotiations and the resulting ramifications to supply chains and business models (which will continue beyond August 1), we anticipate both GPs and LPs will continue inching forward on a positive path and harnessing opportunities as they adjust across more insulated and top performing sectors. AI has continued to shine, with startups raising $104.3 billion in the U.S. in the first half of this year, nearly matching the $104.4 billion total for 2024.4 This was led by OpenAI’s $40B raise and Meta’s $14 billion investment in ScaleAI.

With tech tailwinds, global venture investment logged its strongest half-year since the first six months of 2022,5 signs of a potential recovery taking shape despite the more volatile backdrop. Secondaries reached a new record pace in H1 2025, with $102 billion in transaction volume and high-quality buyout portfolios generally trading at tight single-digit discounts. More than 70 continuation vehicles closed in the first half of the year, 6 providing GPs a strategic tool for boosting liquidity, returning capital to LPs, and strategically building momentum for future fundraising efforts for when markets gain greater clarity.

Have tariffs changed HarbourVest’s approach? Will they?

Our long-term investment approach continues to emphasize fundamental business and manager performance across economic cycles, supported by disciplined portfolio diversification and a large private markets dataset from which to derive insights. While we took tactical steps following Liberation Day including reassessing pending investments for tariff exposure, conducting a portfolio-wide review of potential impacts, and identifying dislocation-driven opportunities, our core evaluation process has remained intact. As trade negotiations evolve, we incorporate new developments into our investment evaluations, seeking to ensure each opportunity is assessed in light of the most current policy landscape.

Sector exposure plays a critical role in how tariffs affect private markets portfolios. HarbourVest’s allocations are weighted toward services-oriented sectors such as technology, business services, financial services, and healthcare, which have historically shown more resilience to trade-related disruptions. In contrast, sectors like consumer goods, manufacturing, and industrials — though a smaller portion of our portfolio — are more directly exposed to tariff pressures and global supply chain volatility. These differences underscore the importance of sector-aware portfolio construction and ongoing monitoring of macroeconomic developments.

In this environment, private markets investors must rely on rigorous due diligence and case-by-case evaluation to identify durable businesses capable of weathering uncertainty. Our focus on middle and lower-middle market companies, which are generally less reliant on global trade, provides some insulation from broader geopolitical risks. Even as we monitor the potential for a broader economic slowdown, we believe businesses will continue to invest in technology and operational efficiency, reinforcing the value of our long-term, fundamentals-driven strategy.

Does August 1 mark a return to normalcy?

The elevated tariff regime under the Trump administration is not a temporary anomaly. It marks the beginning of a new normal in US trade policy. Tariff rates have reached levels not seen in nearly a century, and while some of the initial shock has been absorbed, the broader implications are still unfolding. The administration’s approach is highly personalized and bilateral, with country-by-country negotiations that often lack formal documentation, creating both flexibility and uncertainty. Deals like the one with Japan illustrate how informal arrangements can be revisited or reshaped, while countries like Korea are navigating sector-specific ambiguity due to delayed negotiations. The Brazil and Canada agreements, which include significant exemptions, show how tailored deals are shaping expectations and market reactions.

Legally, the situation remains fluid. The Court of International Trade struck down the IEEPA tariffs in May, and the case is now under appeal at the US Court of Appeals for the Federal Circuit, with a decision expected in late August or early September. A Supreme Court review could follow, but the practical impact of any ruling may be limited if bilateral agreements are finalized in the interim. The administration has positioned the tariffs as a one-time price adjustment, and while rates are currently landing in a range that markets can tolerate — generally around 15%, higher than hoped but lower than feared — there is still a seven-day window for further negotiation. The threat of tariffs in the hundreds of percents has receded, but this is not the end of the story.

Looking ahead, trade negotiations with countries not yet under agreement will continue, and revisions to USMCA are expected to begin in late 2025 or early 2026. Enforcement actions and transshipment crackdowns are likely post-midterms, as the administration builds capacity and political momentum. For private markets, this evolving landscape has already slowed deal flow and accelerated regionalization. Investors must remain vigilant, adjusting underwriting and portfolio strategies to reflect shifting trade dynamics. While the current environment is manageable, the risk of disruption remains, and the structure of future deals — especially with China — will be critical in shaping the next phase of this new normal.

Any final thoughts?

Private markets investing is a distance race, not a sprint, and there are many miles to go to reach the tariff finish line. The landscape remains fluid, shaped by varying sectoral impacts, evolving bilateral deals, and a legal framework that is still being tested. Ultimately, though, the August 1 checkpoint offers investors a chance to recalibrate with a clearer sense of the course ahead.

While surprises are inevitable, the tools to respond — data-driven insights, sector awareness, and investment discipline — are already in hand. With thoughtful due diligence and a commitment to diversification, investors can navigate this terrain with increased confidence. The ability to evaluate opportunities on a case-by-case basis, factoring in both macro risks and micro fundamentals, will be key to identifying resilient businesses and generating sustainable returns.

The race continues and with each mile marker the path forward becomes more defined.

Continuation solutions encompass a host of transaction types in which a GP secures interim liquidity and/or additional primary capital for their LPs in a strongly performing asset, or set of assets, that the GP will continue to own and control. Specifically, they include continuation funds, new funds created by GPs for the purpose of acquiring the asset(s) that continue to be managed by the same GP and capitalized by one or several secondary buyers, or equity recapitalizations involving a direct equity or structured equity investment into a portfolio company. These transactions can also include a parallel investment from the GP’s latest fund into that same pool of assets (a “cross-fund trade”).
