CBN Slashes 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, marking the third consecutive cut in the one-year bill's stop rate to 16.62%. This decline from 16.84% in early September reflects a sustained repricing trend as the central bank manages liquidity and yield curves ahead of upcoming monetary policy decisions. The move signals a continued easing stance in short-term instruments even as the benchmark MPR remains held at 26.50%.
Rand Weakens as Dollar Strengthens Post-GDP Release
On Thursday, September 10, 2026, the South African rand weakened against the dollar as mixed domestic economic data, including a disappointing GDP print, failed to offset global headwinds from a stronger greenback and higher oil prices. Traders remained cautious ahead of US inflation data, which is critical for determining the Federal Reserve's interest rate path and, by extension, emerging market currency flows. Despite the intraday slip, the rand had steadied earlier in the week following the release of manufacturing and current account figures.
Naira Official Rate Weakens Slightly Amid Record Reserves
Data from September 9, 2026, showed the naira weakening to ₦1,322.90 per dollar at the official market, while external reserves rose to $54.209 billion, a level not seen in 18 years. This divergence highlights the CBN's success in building buffers, even as parallel market rates remain elevated at ₦1,390 per dollar. The narrowing gap between official and black-market rates continues to be a key metric for the CBN's stabilization strategy.
Local view
Nigerian financial media highlighted the CBN's strategy of reducing spot rates on Open Market Operations (OMO) and Treasury Bills to stimulate economic activity. Nairametrics reported that OMO maturities surged 31% to N2.94 trillion this week, with total system inflows exceeding N3 trillion for a second consecutive week, suggesting ample liquidity in the banking sector.
In Hausa-language coverage, Matattarar Labarai noted that while macroeconomic indicators like reserves are strong, ordinary Nigerians are still waiting to feel the impact of these gains, with Tori.ng reporting that the CBN has promised these benefits will soon reach households and businesses.
