Interest Rates Slow Seller Activity
One unexpected impact of fluctuating interest rates was the sudden slowdown in seller responsiveness when rates spiked. Many homeowners who were previously open to selling—and had low fixed-rate mortgages—started holding off, unsure of their next move. That led to fewer deals in the pipeline, even though our marketing spend hadn't changed.
This shift forced us to adjust our financial planning by tightening variable expenses, pausing non-essential upgrades, and doubling down on warm leads and referral sources. We also diversified into more creative finance deals and lease options to stay active while traditional seller activity cooled.
It was a reminder that interest rate shifts don't just affect buyers—they influence seller psychology too, and your plan needs to adapt quickly.
Warehouse Expansion Plans Halt
One unexpected impact we've experienced due to fluctuating interest rates at Fulfill.com has been the dramatic shift in warehousing expansion strategies across our 3PL network. When rates climbed rapidly last year, several of our warehouse partners who had been in aggressive growth modes suddenly hit the brakes on expansion plans.
This created an interesting ripple effect that directly impacted our matching algorithms. Previously, we could confidently project new capacity coming online in key geographic regions, allowing us to match growing eCommerce brands with 3PLs that were expanding. When interest rates spiked, those capacity projections became unreliable as capital expenditure budgets were frozen.
From a financial planning perspective, we had to pivot quickly. We adjusted our partner onboarding timelines and reallocated resources toward optimizing existing warehouse operations rather than focusing predominantly on new facility integrations. This meant investing more in our WMS integration capabilities and less in geographic expansion support.
What surprised me most was how this interest rate impact created downstream inventory holding cost changes for merchants. Many of our eCommerce clients suddenly faced much higher carrying costs for their inventory. This shifted demand toward 3PLs offering more flexible storage terms and payment schedules rather than those with the newest facilities or automation.
We adapted by developing new financial modeling tools that help our merchants understand the true landed cost of their inventory, factoring in these rate-sensitive components. This unexpected pivot actually strengthened our value proposition, as merchants increasingly relied on us to help them navigate not just logistics decisions but the financial implications of their fulfillment strategies in a volatile interest rate environment.
The lesson? In the 3PL world, interest rates don't just affect the cost of capital – they fundamentally reshape how capacity is deployed across the entire fulfillment ecosystem.
Adjustable Mortgage Costs Spike
One unexpected impact of fluctuating interest rates was the increased cost of my adjustable-rate mortgage. As rates rose, my monthly payments spiked, straining my budget. This impact highlighted the importance of carefully considering loan terms and planning for potential rate changes. To mitigate future risks, I refinanced to a fixed-rate mortgage, providing payment stability. A pro tip is that when interest rates are volatile, opting for fixed-rate loans can offer predictability and safeguard against unmanageable payment hikes.
HELOC Payments Balloon Unexpectedly
One unexpected impact I experienced was how quickly home equity line of credit (HELOC) payments ballooned when interest rates spiked.
Originally, the low rates made borrowing feel almost harmless—a great tool for renovations and investments. But when rates climbed, my minimum payments jumped significantly, almost overnight. It wasn't catastrophic, but it definitely threw off my short-term cash flow planning.
How it changed my financial planning:
Now I always build in a rate buffer for any variable-interest debt. I assume rates could rise by at least 2-3% over the life of a loan or credit line when modeling payments. It has made me much more conservative about using leverage, even for "good" debt.
The big lesson?
Low rates feel permanent—until they aren't. Always plan for the upside risk, not just the upside opportunity.
Client Decision Timelines Lengthen
One unexpected impact we felt at Gotham Artists from rising interest rates wasn't on loans or credit — it was on client decision timelines. Suddenly, event organizers (especially at mid-sized companies) were taking much longer to approve speaker budgets. CFOs became tighter with sign-offs, and what used to be a 2-week "yes" turned into a 6-week "still waiting on finance."
It forced us to rethink our cash flow assumptions. We started modeling delay risk into our planning — not just deal size, but deal timing. We also adjusted outreach to target more cash-resilient sectors like SaaS and health, and less in industries that tighten up quickly under rate pressure.
Interest rates don't just affect your bank account — they ripple into how your customers behave. If you're not building that into your forecast, you're not seeing the full picture.
