September 2026: planning with room to adapt

Reference month: September 2026 · Retrospective prepared on 16 October 2026 · Mr. Hasan Demirtas

A budget is a set of decisions about the future. Its usefulness depends on whether the assumptions remain visible when circumstances change. September’s outlook offers a valuable context for reviewing those assumptions as companies prepare commitments that extend into the following year.

The September assessment

The OECD’s 23 September outlook projected global growth of 2.9% in 2026 and 3.0% in 2027. Its G20 headline-inflation forecasts were 4.1% and 3.6%, respectively. It identified persistent energy disruption and higher financing costs as risks. These figures relate to the named aggregates and forecast years, rather than a single company’s expected costs.

HTA perspective: make flexibility specific

Our interpretation is that flexibility becomes meaningful when it is attached to an actual decision. Which purchase can be staged? Which delivery date has room to move? Which commitment becomes irreversible after approval? These questions are more useful than a general promise to remain agile.

In a project budget, fixed and adjustable items should be visible separately. A confirmed quotation has a different status from an allowance, and an agreement to review a price is different from permission to change it unilaterally. Clear descriptions protect the quality of the discussion and help parties understand what has genuinely been settled.

The same discipline applies to planning for the next year. A longer horizon gives more time for assumptions to change. Instead of treating uncertainty as a single contingency amount, a review can identify the commercial event that would trigger a reassessment. The purpose is to understand the decision, its timing and who needs to participate.

A constructive follow-up

The next monthly discussion should focus on changes since the last agreed position. Which quotation has expired? Which dependency has been resolved? What has moved from assumption to confirmation? Keeping this record concise helps a team act without losing the wider perspective. For an international partnership, room to adapt works best when both the ambition and the boundaries of the commitment are clearly understood.
