What 7.8% inflation means for the cost of capital in Botswana

Inflation is easing, slowly

Annual inflation eased to 7.8% in September 2026, from 9.3% in August and 9.4% in July. It remains above the Bank of Botswana’s medium-term objective range of 3% to 6%.¹ The Monetary Policy Rate has been unchanged at 5.5% in the central bank’s recent auction notices.¹

The IMF expects the pressure to last. Its October outlook has inflation averaging 7.2% in 2026, up from 5.1% in its April forecast, and 7.4% in 2027, up from 5.7%.² Part of September’s fall reflects a base effect, since inflation jumped to 3.7% in September 2025, and fuel-linked transport costs were still the largest single contributor, according to a report citing Statistics Botswana data.³

A sovereign under watch, and a tighter budget

In September S&P Global Ratings maintained Botswana’s sovereign ratings at BBB-/A-3 with a negative outlook.¹ The 2026/27 budget, presented in February, plans revenue and grants of P77.22 billion against expenditure and net lending of P103.58 billion, a deficit of P26.35 billion.⁴

Businesses feel the tax measures directly. Corporate income tax rises from 22% to 25%. An extra 2.5% applies to taxable income above P400,000 a year, for a top marginal rate of 27.5%. The standard VAT rate stays at 14% but the zero-rated list is being reduced, and mandatory eInvoicing starts in April 2026.⁴

What it means for borrowers and lenders

This is our reading of those facts, not a forecast:

• Each pula has to work harder. Higher rates and a heavier tax bill raise the return a project or stock line must earn before it adds value.
• Timing matters more. When funding is dearer, the days between paying a supplier and being paid by a customer are expensive. Short cycles win.
• Better records help lenders. eInvoicing should make sales data cleaner, which favours funders who lend against confirmed invoices and orders.
