Top developments
Naira strengthens on CBN Dollar Intervention
On September 10, the naira rebounded to ₦1,328.22/$ from ₦1,334/$ the previous day after the Central Bank of Nigeria sold approximately $151 million to boost dollar liquidity in the official market. This intervention highlights the CBN's continued active management of exchange rate volatility despite recent improvements in foreign reserves. The black market rate also adjusted, trading at approximately ₦1,390 sell and ₦1,380 buy on September 11, narrowing the gap with the official window.

CBN Allots N1.05 Trillion as NTB Stop Rates Fall
The CBN allotted N1.05 trillion at its September 9 Treasury Bills primary market auction, cutting the stop rate on the one-year bill to 16.62%. This marks the third consecutive cut in the benchmark bill rate, reflecting strong demand where subscriptions significantly exceeded the offer size. Despite the falling bill yields, market analysts note that capital remains expensive due to higher-yielding Open Market Operations (OMO) bills and global rate pressures.

South African Rand Subdued Ahead of Economic Data
The South African rand traded sideways in early September as investors awaited critical domestic data, including GDP, current account balances, and mining production figures. On September 10, the currency edged up slightly before these releases, with traders also monitoring US inflation data that could influence the Federal Reserve's path. The SARB has held its repo rate at 7% since May 2026, with the next policy meeting awaited for further guidance on inflation risks.

BOI Raises N274 Billion in Inaugural Bond
The Bank of Industry (BOI) successfully raised N274.18 billion through its inaugural domestic bond, exceeding its initial target of N250 billion. This oversubscription signals strong institutional appetite for long-term local currency instruments in Nigeria, even as short-term bill yields fluctuate. The success of the BOI bond suggests that investors are willing to lock in longer-duration returns, potentially stabilizing the long end of the yield curve.
Local view
Hausa-language media outlets highlighted the CBN's intensified scrutiny of banks regarding anti-money laundering and counter-terrorism financing compliance, noting that the central bank is strengthening oversight mechanisms. Additionally, local reports emphasized the record-high foreign reserves, which reached $54 billion, marking an 18-year high and providing a buffer for external debt servicing.
