S&P Global‘s move to buy a majority stake in Nigeria’s Agusto & Co. signals a decisive bid to shape the Africa ratings market just as African policymakers prepare to launch their own continental agency, AfCRA, in October.

S&P’s strategic bet on local credit expertise

S&P Global Ratings agreed on 28 July 2026 to acquire a majority stake in Lagos-based Agusto & Co., Nigeria’s oldest credit rating agency. The deal will close in the second half of 2026, subject to regulatory approval. Financial terms were not disclosed. Agusto, founded in 1992 by Nigerian economist Olabode Agusto, operates across Nigeria, Kenya, Ghana and Rwanda. This gives S&P an immediate domestic footprint in four key African markets.

Agusto will continue to operate as an independent ratings agency under its existing licences and regulatory approvals. It will retain its own methodologies while benefiting from S&P’s global analytics and systems. S&P Global Ratings President Yann Le Pallec has framed the investment as a strategic step that supports the group’s long-term growth strategy in Africa. It also deepens coverage in local currency debt markets.

The timing matters. The deal comes just over two months before the African Peer Review Mechanism is due to launch the African Credit Rating Agency (AfCRA) in Mauritius on 6 October 2026, under an African Union mandate. AfCRA has been structured as a private sector-led institution with no African government ownership. This design is intended to protect its independence and credibility while offering context-rich assessments of sovereign and corporate risk. It will start with local currency ratings before moving into foreign currency sovereign ratings. That directly addresses the part of the Africa ratings market where domestic agencies like Agusto already operate.

AfCRA, risk premia and the battle for Africa’s narrative

S&P’s entry via Agusto lands in the middle of an active debate over how global markets price African risk. African policymakers and multilateral institutions have argued that international rating agencies overstate political and economic risks. This contributes to higher borrowing costs for sovereign issuers. Estimates linked to the United Nations Development Programme suggest this “Africa premium” may cost African economies as much as US$75 billion through higher financing costs.

Only 32 of Africa’s 54 sovereigns currently have publicly available international credit ratings. That leaves sizeable gaps in coverage that both global firms and new African entrants are keen to fill. For investors, S&P’s deal can be read in two ways. On one hand, it may strengthen market infrastructure. Pairing Agusto’s three decades of local knowledge with S&P’s global methodologies, data and investor reach could improve transparency in corporate bond markets. It could also deepen liquidity in local debt, especially in Nigeria where Agusto has long dominated domestic ratings.

On the other hand, AfCRA’s architects worry that growing acquisitions of African agencies by global players could reduce competition. They also warn it may narrow the range of independent views on African credit risk. Misheck Mutize, the APRM’s lead expert on AfCRA, has warned that consolidation may limit alternative assessments and reinforce existing global narratives about African sovereign risk. Importantly, AfCRA was not designed simply to deliver higher ratings. It aims to apply methodologies that better capture structural reforms, regional integration and domestic policy efforts often underweighted in traditional models.

For capital-markets participants, the emerging Africa ratings market will likely become more contested rather than less. A stronger S&P-Agusto platform could give international investors greater comfort in local currency instruments and corporate issuance. AfCRA offers an additional benchmark for those seeking a more context-sensitive view of sovereign risk. Cross-comparison between AfCRA, Agusto and the global “big three” may become part of standard credit work on African portfolios.

Investors should now watch three things: regulatory approval and integration of the S&P–Agusto deal, AfCRA’s ability to build early market credibility after its 6 October launch, and how sovereigns and corporates choose among competing rating providers as they seek to reduce the Africa premium and broaden access to global capital. The balance struck between these forces will define who sets Africa’s risk narrative — and where the next opportunities emerge in the Africa ratings market.
