Planning for the Unknowns: Tariffs, Interest Rates, and Economic Shifts

If there is one certainty in business, it is uncertainty. At Main Street IQ, we advocate moving beyond treating unexpected events as rare occurrences, instead encouraging businesses to build resilience through preparation rather than perfect prediction.

Common Unknowns in 2026

The risks facing businesses fall into two categories:

Macro unknowns encompass economy-wide shifts affecting consumer sentiment, interest rates, inflation, and capital availability. While analysts anticipate interest rate cuts in 2026, the reality may differ. Plans should model both favorable and slower-than-expected scenarios.

Micro unknowns include category-specific shocks such as tariffs, raw material shortages, vendor instability, and retailer defaults. These often arrive suddenly and significantly impact cash flow.

Scenario Planning & Sensitivity Analysis

Rather than creating a single forecast, build three distinct scenarios:

• Baseline: Expected conditions.
• Upside: Accelerated rate cuts, cost reductions, or increased consumer demand.
• Downside: Elevated tariffs, supply chain disruptions, or unexpected sales declines.

Sensitivity analysis should stress-test critical assumptions: interest rate movements, tariff impacts on costs, and changes in customer retention rates. This advance preparation enables rapid decision-making when conditions shift.

Industry-Specific Best Practices

DTC Brands

• Model shipping and logistics volatility.
• Diversify marketing channels beyond Meta and Google.
• Prepare for tariff shocks affecting apparel and accessories.

A DTC apparel company experienced an 8% COGS increase from tariffs and significant margin compression. By diversifying suppliers and marketing partnerships, they built the resilience needed to absorb future shocks.

Multiline Omnichannel Retailers

• Budget markdown reserves for consumer spending dips.
• Develop regional scenario models.
• Assess debt and lease sensitivity to interest rate changes.

A regional retailer failed to budget for markdowns during higher-than-expected interest rates, leading to Q3 margin erosion. The experience prompted the development of more sophisticated scenario planning for 2026.

Wholesale

• Model credit risk from retailer payment delays or insolvency.
• Plan for tariff impacts on imported goods.
• Develop seasonal financing scenarios for upfront inventory builds.

A wholesale furniture company faced a $10M retailer order combined with 12% tariff increases and stretched payment terms, creating significant cash flow stress. The lesson: diversified customer bases and flexible credit facilities are essential.

RAID Framework Application

RAID — Redundancy, Agility, Intelligence, Data-driven — is essential for managing uncertainty:

• Agile: Plans that permit rapid pivots when conditions change.
• Intelligent: Tools enabling quick multi-scenario modeling.
• Data-Driven: Monitoring leading indicators before problems emerge.
• Redundant: Maintaining backup suppliers and diversified channels.

KPIs & Measurement Cadence

Resilient companies track leading indicators across multiple timeframes:

• Weekly: Customer acquisition costs, fulfillment expenses, accounts receivable collections, cash balances.
• Monthly: Inventory turnover, markdown reserves, contribution margins.
• Quarterly: Scenario refreshes aligned with macro conditions.

Cross-Functional Collaboration

Effective uncertainty management requires alignment across departments. Sales must understand pipeline implications, marketing must adjust spending based on acquisition cost changes, and operations must pivot suppliers when tariffs shift. Including department heads in scenario planning from the beginning builds organizational buy-in.

Closing Thoughts

Planning for uncertainty means building organizational adaptability rather than achieving forecast accuracy. Interest rate cuts, while potentially beneficial, remain uncertain. By implementing scenarios, applying RAID principles, and aligning metrics across functions, companies can maintain momentum despite inevitable disruptions.

The best businesses are not those that avoid every storm — they are the ones that keep moving forward when storms inevitably hit.
