Stress tests indicate commercial real estate risks remain manageable

Botswana’s banking sector continues to demonstrate resilience against credit and interest rate risks, with the Bank of Botswana’s latest stress tests confirming stability under moderate conditions. Yet, the central bank warns that more severe scenarios could reveal vulnerabilities within property lending.

Deputy Governor Dr Kealeboga Masalila provided insights in response to inquiries about the Monetary Policy Committee’s stress testing results, focusing on commercial real estate (CRE) debt-servicing risks, potential defaults, and exposure to interest rate fluctuations. He emphasised that risks are mitigated through robust internal risk management by banks, regulatory oversight, and interventions by the central bank itself.

“Risk management operates on two fronts: within banks’ own controls and through regulatory frameworks supported by our policy measures,” Masalila explained.

The stress tests affirm a stable outlook under moderate shocks, but challenges emerge when the scenarios extend to more extreme conditions. “The moderate stress tests continue to show stability. It is only when we apply extreme scenarios that vulnerabilities become apparent,” he said.

Masalila stressed that these extreme stress test outcomes serve as a call for vigilance rather than an immediate cause for alarm. He highlighted that many loans are secured by collateral such as mortgages and asset-backed financing, which provide a buffer against losses amid economic or interest rate downturns.

The Deputy Governor also pointed to the 2022 GDP gap as an additional signal that the financial system remains insulated from significant instability, though he underlined the necessity of ongoing risk management. “This is a risk to be managed carefully,” he said, urging continued prudence.

This assessment arrives amid rising concerns over the capacity of commercial property borrowers to meet debt obligations if interest rates persist at elevated levels or climb further. Higher borrowing costs could strain highly leveraged projects, while weaker economic activity might depress rental incomes.

While the Bank of Botswana does not currently interpret the stress test findings as signalling widespread instability, it acknowledges that vulnerabilities intensify under extreme scenarios. This underscores the importance of banks maintaining strong safeguards and monitoring at-risk borrowers closely.

Masalila’s commentary offers a broadly reassuring macroprudential picture: Botswana’s banking sector can weather moderate stress, though severe shocks could pose manageable challenges. Yet, the details necessary for market participants to accurately assess CRE risks remain limited. Understanding the magnitude of interest rate shocks applied, anticipated rental and vacancy trends, the proportion of CRE lending, floating-rate exposure, and the projected impact on non-performing loans and capital ratios would enhance transparency. Without this, market actors cannot gauge what constitutes a “moderate” or “extreme” shock – whether, for example, a 200 to 300 basis-point rate rise or a smaller adjustment.

This opacity is notable given signs of financial strain. Household lending fell by around P2 billion in May 2026 amid persistently high borrowing costs. Meanwhile, property market insiders report that elevated commercial bank rates are slowing transactions and squeezing cash flows.

The argument that collateral mitigates risk may overlook a critical factor: rising interest rates tend to depress property valuations and rental yields, thereby eroding collateral coverage even when borrowers remain current. This dynamic could compel banks to increase provisions or tighten credit to the CRE sector.

A more transparent communication strategy would include a high-level overview of CRE-specific stress test results, detailing shifts in non-performing loan ratios and capital buffers under defined interest rate and property market shocks, alongside clear supervisory guidance on underwriting and interest rate risk.

Until such information is forthcoming, the prudent conclusion is that Botswana’s CRE market remains broadly stable under current policy settings. Nonetheless, significant leverage, exposure to floating-rate debt, and optimistic rental income assumptions represent vulnerabilities that could intensify if interest rates stay elevated or economic growth falters.
