South African Bond Yields Rise on Inflation Concerns

South Africa's 10-year government bond yield climbed toward 8.9%, its highest level since May 19, as investors weighed the South African Reserve Bank's surprise decision to leave interest rates unchanged against rising oil prices and mounting inflation risks. The SARB voted 4–2 to keep its benchmark repo rate at 7.0%, despite market expectations for at least a 25-basis-point hike, citing a modestly improved inflation outlook and weaker economic growth. Governor Lesetja Kganyago warned that higher oil and fertilizer prices stemming from renewed conflict in the Middle East could require further tightening if they spill over into food prices and core inflation. Annual inflation accelerated to 5.0% in June, a two-year high and above the upper end of the SARB's target range, while rising oil prices reinforced expectations that additional policy tightening may still be needed this year.

South Africa's 10-year government bond yield climbed to 8.85%, its highest level since May 19, as investors positioned ahead of Thursday's South African Reserve Bank policy decision after stronger-than-expected inflation data fueled expectations of a larger interest rate hike. Annual inflation accelerated to 5.0% in June, the highest in two years, from 4.5% in May and above forecasts of 4.7%, driven mainly by higher transport and housing costs. Core inflation also rose to 4.1%, its highest reading since September 2024. While markets continue to expect the SARB to raise its benchmark rate by 25 basis points to 7.25%, the latest inflation figures have revived expectations of a 50bp move. The central bank considered such an increase at its May meeting, and with inflation now exceeding the revised 4.0% upper bound of its 3% ±1 percentage point target range, the case for a more aggressive hike has strengthened.

Annual inflation accelerated to 5.0% in June, the highest in two years, up from 4.5% in May and above market expectations of 4.7%, driven primarily by transport and housing and utilities. Core inflation also picked up to 4.1%, its highest reading since September 2024. With both headline and core inflation remaining above the South African Reserve Bank's 3% target, markets continue to price in a 25-basis-point interest rate hike to 7.25% at Thursday's policy meeting. Meanwhile, oil prices rose to their highest level in more than a month as Middle East tensions escalated after US President Donald Trump warned of further strikes on Iran and pledged retaliation if Iran-backed Houthi rebels disrupt shipping through the Red Sea.
