First National Bank has warned that rising inflationary pressures could lead to further interest rate increases in South Africa after the central bank lifted borrowing costs in response to global economic shocks.
The South African Reserve Bank raised its benchmark repo rate by 0.25 percentage points to 10.50 percent, a move that has already translated into higher lending costs across the economy. Following the decision, First National Bank adjusted its prime lending rate in line with the increase, reinforcing tighter financial conditions for households and businesses.
FNB Chief Executive Officer Lytania Johnson said the rate hike reflects external pressures largely beyond the control of domestic policymakers. “While the increase is a measured response to rising inflationary pressures, it comes at a challenging time for the domestic economy, which continues to require stronger growth and job creation,” she said.
The bank pointed to a sharp rise in global oil prices as a key driver of inflation. Prices have climbed by more than 55 percent in the past six months, rising from around $60 to above $100 per barrel. This surge has significantly increased input costs across multiple sectors, particularly in energy-dependent industries, and is now feeding into broader consumer price inflation.
Johnson noted that inflationary pressures began intensifying earlier in 2026 and are expected to remain elevated through 2027. She warned that ongoing geopolitical tensions, particularly in the Persian Gulf, continue to create uncertainty in global energy markets, complicating inflation forecasts.
“A near-term solution could result in lower oil prices and a subsequent reassessment of current inflation forecasts,” she said, suggesting that geopolitical developments could still alter the trajectory of price growth.
FNB Chief Economist Mamello Matikinca-Ngwenya said expectations for interest rate cuts this year have largely faded, increasing financial strain on consumers and businesses already grappling with high borrowing costs. She explained that while consumer confidence showed modest recovery toward the end of 2025 and early 2026, it remains fragile.
The focus, she said, has now shifted to so-called second-round inflation effects, where rising input costs force businesses to increase prices, passing the burden on to consumers. “These second-round effects are expected to develop as input cost pressures drive suppliers to increase consumer prices, initially impacting industries most sensitive to energy prices before filtering through the broader economy,” Matikinca-Ngwenya said.
The Reserve Bank’s rate hike is aimed at containing these risks by reducing demand and limiting the spread of inflation throughout the economy. However, tighter monetary policy also slows economic activity, creating a delicate balance between controlling inflation and supporting growth.
Matikinca-Ngwenya warned that future policy decisions will depend heavily on inflation expectations, particularly ahead of the next Monetary Policy Committee meeting. “Should expectations reflect the risk of a prolonged shift away from the 3 percent inflation target, the SARB may have to raise rates more aggressively to protect the credibility of a lower inflation regime,” she said.
The warning highlights the central bank’s commitment to maintaining price stability, even if it means imposing further financial pressure on the economy. Higher interest rates increase the cost of borrowing for mortgages, business loans, and consumer credit, which can dampen spending and investment.
FNB said the current environment calls for caution, urging consumers to carefully consider major debt-financed purchases. Johnson warned that additional rate hikes remain possible in 2026, particularly if inflation continues to rise or global conditions worsen.
The bank also encouraged customers to use digital financial management tools to better navigate the challenging environment. Platforms such as FNB’s nav system offer budgeting support and financial planning services, helping individuals manage rising costs and debt obligations.
Despite the challenges, FNB said it remains committed to supporting customers through tailored repayment solutions and debt relief options. The bank advised clients experiencing financial difficulties to engage proactively through its digital channels or branch network to explore available assistance.
The broader economic outlook remains uncertain as South Africa faces the combined effects of global inflation, energy price volatility, and domestic growth constraints. While the central bank’s actions are intended to stabilize prices, the impact on economic momentum is likely to become more pronounced in the months ahead.
As inflation risks persist and interest rates remain elevated, businesses and households alike will need to adapt to a more restrictive financial environment, with policymakers closely monitoring developments to determine the next course of action.
