How Interest Rates Affect VC Funding for Startups

How Interest Rates Influence Equity Investors

When lower-risk investments, such as Treasury securities, offer higher yields, investors have more attractive alternatives to taking startup risk. Venture investments need to compensate investors for significant uncertainty, long-term illiquidity, and the very real possibility of losing their capital. A change in the risk-adjusted return available elsewhere easily influences how they evaluate that trade-off.

Interest rates broadly affect startup funding at two levels. First, investors may change how much they commit to venture funds themselves, and secondly, venture funds may change which startups they back, and the terms they offer. Investors backing venture funds are called limited partners. Their willingness to make new commitments to funds helps determine the capital available for future fund investments into startups. Many existing funds have multiyear commitments and investment mandates, so a rate change does not necessarily mean they can simply move their capital into bonds.

The OECD’s review of venture financing describes how rising rates in 2022 helped redirect capital toward fixed-income investments and reduce liquidity in VC markets. The implication is that demand for your equity depends partly on financial conditions beyond your company’s specific performance.

How Higher Rates Can Put Pressure on Valuations

Higher interest rates can raise the potential return investors expect from a startup. When lower-risk, more-liquid investments also offer better yields, investors need stronger reasons to commit money to an uncertain outcome that may take years to materialize.

One way to increase that potential return is to pay less upfront. If an investor expects a particular equity stake to be worth $10 million at exit, paying $2 million for that stake offers a potential 5× return, compared with 4× at $2.5 million. If expectations for your business remain unchanged, investors may push for a lower valuation to make the investment attractive.

The time until that return materializes also matters. Receiving the same proceeds in ten years produces a lower annualized return than receiving them in five. Companies with a longer path to cash generation or exit can therefore face additional valuation pressure.

Your company’s progress can help offset that pressure. Strong revenue growth, high retention, improving margins, or technical breakthroughs may give investors reason to expect a more valuable business and thus higher subsequent valuations. But meeting your operating targets alone doesn’t guarantee a higher valuation in your next round. Investor return expectations may have changed since your last raise.

Why Exits and Fund Liquidity Also Matter

Interest rates affect how investors eventually earn a return on your startup. Higher borrowing costs can make acquisitions more expensive to finance, potentially reducing what buyers will pay. Lower public-company valuations can make an IPO less attractive. Both can delay exits or reduce the proceeds available to venture investors.

When exits slow, venture funds may take longer to return cash to their limited partners. Those investors, in turn, may then have less capacity or willingness to commit to new funds. That can affect the broader supply of capital available for future startup investment.

How Quickly Do Rate Changes Affect Startup Funding?

There is no single timetable. Market expectations can shift before a policy decision, while fund commitments, company valuations, and financing processes adjust over longer periods.

Research suggests that monetary tightening can reduce venture investment over the following one to three years, although the timing and magnitude vary.

The practical lesson is to allow time for changing conditions. A rate cut doesn’t guarantee that your next raise will become easier. If the cut responds to a weakening economy, customers and investors may remain cautious. Conversely, a rate hike doesn’t mean your next raise will be impossible. Funding conditions can also vary widely by sector and company stage. A few large rounds can lift overall investment totals while other startups struggle to raise, as we’ve seen with AI. If possible, assess investor interest in companies like yours when planning your next round.

Plan Your Raise for Changing Funding Conditions

Start with the evidence you need to create before the next financing. At seed stage, that might mean demonstrating technical functionality, product demand and/or reaching milestones. A Series A company may need clear evidence of repeatable customer acquisition, retention and positive economics at scale. A growth-stage company, meanwhile, may need to show significant expansion will produce more attractive margins, a path to positive cash flow and profitability.

Then calculate what it costs to get there, including the cash needed to operate while you raise again. A plan that reaches its milestone just as the bank balance runs out gives you little maneuvering room for diligence, legal prep or a delayed close. Note this impacts valuation as well – a startup about to bounce checks has little negotiating power.

Use a financial model with scenarios to test what assumptions like a lower valuation, a smaller round, higher costs or a delayed close would mean for your overall operating plan. Identify which investments are necessary to reach your milestone, and which you can postpone if need be. If funding arrives later or on different terms, know in advance what spending you would change and how much cash runway that would preserve.

Start investor conversations while you still have time to act on what you learn. Ask prospective investors what evidence they would need to lead a round and what concerns may prevent them from moving forward. Utilize their responses to assess whether your milestones and financing assumptions are realistic; if not, adjust them and see what happens to the plan.

As you build your 2027 budget, use these financing scenarios to set hiring and spending commitments. Identify the cash balance or fundraising milestone that would trigger a change in your spending, so you can respond before a delayed round becomes a cash shortage.
