A surge in investor confidence has driven the premium demanded to hold Eskom’s rand-denominated bonds over equivalent government debt to its narrowest level in more than a year, with the spread on the 2033 maturity contracting to approximately 90 basis points from a peak of 155 basis points in May. The dramatic compression signals growing faith in the state-owned utility’s recovery after a decade of financial distress that once led analysts to label it the greatest single risk to South Africa’s economy.
According to data compiled by Bloomberg, the gap has averaged 115 basis points over the past five years, making the current level particularly striking. The rally reflects tangible progress under a comprehensive restructuring programme bolstered by a R254 billion government debt-relief package introduced in 2023, which has enabled Eskom to reduce total indebtedness from R412 billion to R372 billion by March 2025, with a further target of R300 billion within two years.
The utility’s return to profitability has been central to the improved sentiment. For the financial year ended 31 March 2025, Eskom posted an after-tax surplus of R16 billion—its first annual profit in eight years—contrasting sharply with the R55 billion loss recorded the previous period. As reported by Business Day, this turnaround stemmed from rigorous cost containment, enhanced plant availability that eliminated widespread load shedding, and improved revenue collection from municipalities, despite outstanding arrears still exceeding R100 billion.
Bondholders now appear convinced that the risk premium of around 100 basis points adequately compensates for holding Eskom paper rather than sovereign debt, with some market participants suggesting the spread could tighten further to 80 basis points if operational gains persist. The positive momentum extends to Eskom’s dollar-denominated securities, where yields on the unguaranteed 2028 notes have tumbled more than 300 basis points from April highs to a record low of 5.42% by late October, narrowing the premium over US Treasuries to 198 basis points.
Lower borrowing costs arrive at a pivotal moment, as Eskom prepares to re-enter capital markets independently after years of reliance on government guarantees. The utility has outlined plans to raise R75 billion in new rand debt without state backing from 2028 onwards, a move that will test investor appetite for standalone credit risk. Sanlam Investments, the second-largest holder of Eskom bonds, has indicated that sustained reliability in power supply and favourable news flow could cement the utility’s status as a sought-after yield play in an environment starved of attractive returns.
National Treasury officials acknowledged the brighter financial trajectory in Wednesday’s medium-term budget update but cautioned that escalating municipal arrears continue to threaten cash flow. While no fresh support measures were detailed, the department stressed that long-term stability hinges on rigorous execution of operational reforms and disciplined capital expenditure.
The bond market’s enthusiastic response also coincides with broader optimism surrounding South African assets, evidenced by the rand’s strongest performance in years and a sharp decline in sovereign borrowing costs. For Eskom, the cheaper funding environment translates into meaningful savings on interest payments, freeing resources for critical transmission upgrades and the integration of renewable generation capacity.
As the utility edges closer to financial self-sufficiency, the narrowing spreads underscore a remarkable shift from the crisis years when default fears dominated headlines. With generation units performing above expectations and no significant power cuts recorded for over a year, Eskom appears poised to capitalise on restored credibility, potentially paving the way for a credit-rating uplift that would further reduce financing burdens.
