CBN cuts 364-day NTB stop rate to 16.62%
On Wednesday, September 9, 2026, the CBN allotted N1.05 trillion at its Treasury Bills primary market auction, reducing the stop rate on the one-year bill to 16.62%. This represents the third straight cut in recent weeks and follows a total offer size of N500 billion, the lowest for Q3 2026. The declining yields suggest easing pressure on short-term liquidity despite the benchmark MPR remaining unchanged at 26.50%.
Rand slips as oil and dollar outweigh mixed data
The South African rand weakened on Thursday, September 10, as a stronger US dollar and higher oil prices weighed on the currency. Investors assessed a slew of domestic economic data, including manufacturing and mining figures, which offered a mixed view of Africa’s most industrialized economy. The rand had edged up earlier in the week but reversed course amid broader emerging market volatility.
Naira rebounds after CBN injects $151 million
The naira rebounded to ₦1,328.22 per dollar on September 10 after falling to ₦1,334 the previous day. The Central Bank of Nigeria sold approximately $151 million to boost dollar liquidity in the official market. This intervention helped stabilize the naira after a period of slight depreciation, maintaining the currency near its recent two-year highs supported by rising reserves.
FGN launches N1 trillion bond auction with high entry threshold
The Federal Government of Nigeria is seeking to raise N1 trillion in its September 2026 bond auction, with the Debt Management Office (DMO) setting a minimum entry threshold of N50.001 million. This move aims to manage long-term debt sustainability while catering to institutional investors. The auction comes as secondary market yields for Nigerian Treasury bills showed signs of repricing, with average yields climbing to 18.81% earlier in the week before the primary market cuts.
Local view
Hausa-language media outlets such as Matattarar Labarai highlighted the CBN's efforts to maintain financial stability and the impact of external reserves on the naira's strength. Reports emphasized that the central bank's increased supervision of foreign exchange transactions is part of a broader strategy to curb inflationary pressures and ensure orderly market operations.
