Bank of Botswana on Thursday raised its benchmark interest rate by 200 basis points, warning that inflation is set to exceed its target range amid rising fuel costs linked to the Iran war.
The central bank increased its monetary policy rate to 5.5 percent from 3.5 percent, in one of its most aggressive tightening moves in recent years as it seeks to contain mounting price pressures.
Governor Lesego Moseki said inflation is projected to breach the bank’s preferred 3 to 6 percent target band in the second quarter of 2026, before averaging 8.7 percent for the year. Price growth is expected to ease to around 5.6 percent in 2027.
The upward revision reflects recent increases in domestic fuel prices, public transport fares and medical aid premiums, which have combined to push up the cost of living in the southern African country.
“There is a need to recalibrate and reinforce policy transmission and signalling,” Moseki told a press conference, underscoring the central bank’s determination to anchor inflation expectations.

The latest move follows a previous sharp hike in October 2025, when the central bank raised its policy rate by 160 basis points in an effort to close the gap between official rates and commercial lending rates. That divergence had widened due to a liquidity squeeze triggered by an economic downturn.
Analysts say the latest rate increase signals a more hawkish stance by policymakers, who are balancing inflation risks against a fragile economic recovery.
Botswana has been grappling with the fallout from a prolonged slump in the global diamond market, a key driver of its economy. Weak demand and lower prices have led to successive contractions in gross domestic product over the past two years.

The downturn has strained public finances, with the government facing widening budget deficits and rising debt levels. Authorities had initially projected a recovery in 2026, but the outlook has become more uncertain following the recent escalation in global energy prices linked to the Iran conflict.
Higher fuel costs are feeding into broader inflation through transport and production channels, raising concerns about second-round effects on wages and consumer prices.
Despite these pressures, annual inflation remained relatively moderate at 4.2 percent year-on-year in March, up slightly from 4.0 percent in February and still within the central bank’s target range.
However, policymakers expect this to change in the coming months as earlier increases in administered prices and imported inflation begin to filter through the economy.
The central bank said its decision aims to curb demand-side pressures while supporting the transmission of monetary policy through the banking system.
Economists note that tighter monetary conditions could dampen credit growth and consumer spending in the short term, potentially weighing on economic activity.
At the same time, maintaining price stability is seen as critical to preserving investor confidence and supporting long-term growth prospects.
The rate hike also aligns Botswana with a broader trend among central banks globally and in Africa, many of which have tightened policy in response to persistent inflationary pressures and external shocks.
Looking ahead, the Bank of Botswana said it would continue to monitor inflation dynamics, global commodity prices and domestic economic conditions, and stands ready to adjust policy as needed to achieve its medium-term objectives.
The decision highlights the difficult trade-offs facing policymakers as they navigate rising inflation risks against the need to support a still-recovering economy.
