Top developments
Naira Strengthens to Two-Year High on Record Reserves
The Nigerian naira appreciated to a two-year high of ₦1,315.67 per dollar this week, supported by a surge in external reserves to $53.99 billion, an 18-year peak. This resilience is attributed to record remittance inflows in July and a narrowing gap between official and parallel market rates. The naira's strength has allowed the Central Bank of Nigeria (CBN) to maintain its benchmark rate at 26.50% while seeing improved market sentiment.
CBN Cuts Treasury Bill Yields Below 17%
The CBN cut the stop rate on one-year Nigerian Treasury Bills to 16.84% in its September 2 auction, the lowest level since June 3. This marks the second consecutive rate cut, with the bank allotting N865.71 billion against strong demand. Despite the primary market cuts, secondary market yields for T-Bills climbed slightly to 18.81% on Monday as investors repriced holdings ahead of new supply.
South African Rand Subdued Ahead of Economic Data
The South African rand traded subdued on Monday as investors awaited key economic releases, including GDP, current account, mining, and manufacturing figures. The currency had recently strengthened below 16 per dollar, erasing earlier losses linked to geopolitical tensions, but remains cautious amid local economic uncertainty. The South African Reserve Bank (SARB) has held the repo rate at 7.0% since May, with the November municipal elections seen as a key test for the rand's outlook into 2027.
FG Announces N1 Trillion Bond Auction for September
The Federal Government of Nigeria plans to raise N1 trillion in its September 2026 bond auction, with the Debt Management Office (DMO) setting a minimum subscription threshold of N50 million. Additionally, the CBN is scheduled to auction N500 billion in Treasury Bills on September 9, the lowest offer size of Q3 2026, which may temporarily push secondary market yields higher as portfolios reposition.
Local view
Hausa-language media outlets such as Legit.ng Hausa have highlighted the naira's significant appreciation, noting it reached ₦1,315 per dollar, a level not seen in two years. Local reports emphasize the role of the Tinubu administration's efforts in stabilizing external reserves, which have surpassed levels last seen during the Yar'Adua era. Matattarar Labarai also reported on the CBN's success in improving business liquidity and monitoring systems to combat financial crime, contributing to market stability.
