President Trump's aggressive tariff policies are reshaping global commodity markets, creating unprecedented volatility for businesses across sectors.

The recent implementation of 25% tariffs on steel and aluminium imports, coupled with the looming threat of similar measures on copper, has triggered immediate price surges and supply chain disruptions that reverberate throughout the economy. This volatility is further amplified by the on-again, off-again nature of trade policy implementation.

Tariffs can be announced, paused, modified, and escalated within days, as demonstrated by the recent 'Reciprocal Tariff Plan,' which saw tariffs on Chinese goods fluctuate from 10% to 125%, while tariffs on other countries, initially escalated, were paused for 90 days, all within a single week. This policy whiplash leaves businesses in a perpetual state of uncertainty, unable to confidently plan or secure stable supply chains.

U.S. copper prices have already experienced significant premiums over global benchmarks, with the COMEX-LME price gap widening to over $1,200/tonne in recent weeks as traders rush to stockpile inventory ahead of potential tariff implementation. For businesses dependent on these metals, this new reality presents a complex strategic challenge.

This volatile landscape necessitates a fundamental shift in how organizations approach planning and decision-making. The once stable trade environments can no longer serve as a reliable basis for effective business planning.

How can organizations commit to a 5-year strategic plan when tariff policies can change overnight?

Why Traditional Planning Approaches Fall Short in the Tariff Era

Traditional planning approaches that primarily extrapolate historical data at an aggregated outcome level are particularly vulnerable in today's trade policy environment. When a 25% tariff can be announced and implemented within weeks, forecasts based on historical data quickly become obsolete.

Quantifying the additional impact at the outcome level is challenging because the financial model does not isolate levers with the necessary granularity to rapidly run scenarios. Fixed budgets and rigid planning cycles leave businesses unable to respond to sudden cost increases or supply chain disruptions. This new reality demands a more dynamic, agile approach to financial planning and analysis, one that can rapidly assess the impact of policy changes across the entire value chain and enable swift, informed decision-making.

Driver-based modelling provides precisely this capability, offering a framework that connects underlying drivers, including macro-economic assumptions, to operational and financial outcomes. While many companies have adopted more agile planning methods, a significant number still depend on traditional approaches. Even those transitioning to modern methods may face challenges in full implementation.

This underscores the need for continuous adaptation in planning processes to maintain competitiveness in a rapidly changing market.

Integrated Driver-Based Modelling

The foundation of a modern planning capability is an integrated driver-based model that facilitates scenario modelling. Driver-based forecasting offers a dynamic and responsive approach by directly linking financial outcomes to key business drivers.

Unlike traditional methods that rely on top-line forecasting and adjustments to historical outcomes, driver-based models focus on specific factors influencing performance. Assumptions made at the driver level are inherently more accurate because they are based on specific, measurable factors that directly influence outcomes. This approach allows businesses to adapt quickly to changes, providing a more accurate and reliable framework for decision-making.

By establishing a direct connection between inputs, drivers, and outputs, driver-based models enable organizations to conduct scenario analyses and adjust forecasts in real-time. This flexibility is crucial in today's volatile economic environment, where businesses must be prepared to respond to sudden shifts in market conditions.

Let’s demonstrate the complexity of managing a business in this environment by way of an example.

Illustrative Example:

A Base Metals Mining Company in a Tariff-Affected Geography

Consider a base metals mining company operating in a region impacted by steel and aluminium tariffs. These tariffs can significantly alter the company's cost base, affecting decisions across various aspects of the business.

Conclusion:

Driver-Based Modelling as an Essential Tool in Tariff Uncertainty

The importance of a driver-based model lies in its ability to flex different assumptions in a swift and integrated manner across the business. This capability is crucial for balancing the impact of tariffs on input costs with potential benefits on selling prices. Without such a model, managing these complexities becomes extremely challenging, especially for companies with extensive operations and diverse geographical footprints.

As we've seen, the current tariff environment creates both challenges and opportunities for businesses. The winners in this new landscape will be those who can quickly assess the impact of policy changes, model different scenarios, and adapt their strategies accordingly. Driver-based modelling provides exactly this capability, enabling businesses to:

  1. Quantify the direct and indirect impacts of tariffs across the value chain.
  2. Identify which parts of the business are most vulnerable or advantaged.
  3. Test alternative strategies before committing resources.
  4. Communicate the rationale for strategic shifts to stakeholders

As businesses continue to navigate uncertain trade environments, adopting a driver-based forecasting approach is no longer optional, it's essential for survival and success. It empowers organizations to make informed decisions, optimise strategies, and seize opportunities in a rapidly changing world.
