Fed and BoE Split Puts Nigeria, Africa on Watch for Dollar and Inflation Pressure

The US Federal Reserve has resumed raising interest rates while the Bank of England has held, setting the stage for fresh dollar and inflation pressures across Africa. Nigeria is among the economies most exposed to the shifting global financial conditions.

The Fed raised its benchmark rate by 25 basis points to a range of 3.75 to 4 percent on Wednesday, its first increase since 2023. The Bank of England, hours later, held the Bank Rate at 3.75 percent in a 6-3 vote, with three policymakers favouring an increase.

Why the split matters for Africa

For Africa, the significance lies less in Washington's 25-basis-point move or London's pause than in what they could mean for the flow and price of global capital. Higher US interest rates can increase the relative attraction of dollar-denominated assets. A stronger dollar can then raise the local-currency cost of servicing dollar debt and increase the return investors demand for holding emerging-market assets.

Nigel Green, chief executive officer of deVere Group, sees the Fed's move as the beginning of another tightening phase. Green said: “A quarter point today [Wednesday] was the easy part. The harder question is what comes after it, and the honest answer is more tightening, not less.” He predicts another Fed increase in December. That December call remains a forecast, not a commitment by the Federal Reserve.

Nigeria's oil cushion and its catch

Nigeria enters this environment from a stronger external position than in some previous periods of intense currency pressure. External reserves have risen above $54 billion, while the naira has shown greater stability. Inflation has also been moderating, with headline inflation easing to 15.39 percent in August from 15.43 percent in July, according to the National Bureau of Statistics.

Oil remains Nigeria's most important external cushion, but it is also a source of vulnerability. If geopolitical tensions keep oil prices elevated, Nigeria can benefit from higher export earnings and stronger foreign-exchange inflows. But the same oil shock can keep global inflation elevated, encourage major central banks to maintain tighter monetary policies and increase the cost of capital for emerging economies. Nigeria could therefore receive more dollars from oil while operating in a world where those dollars have become more expensive to borrow.

Cost of capital is the real story

For Nigerian companies, the Fed's decision is unlikely to arrive as a line item labelled Federal Reserve rate. It will show up through borrowing costs, refinancing decisions, exchange rates, imported inputs and investor return requirements. A manufacturer importing machinery, an airline buying fuel, a bank managing foreign-currency obligations or a company refinancing dollar debt can all be affected by movements in the dollar and global interest rates.

The government faces the same arithmetic. When US Treasury yields rise, emerging-market sovereign borrowers must consider whether they can continue accessing international capital at acceptable rates. Green has warned investors about duration, arguing that holders of long-dated bonds bought when yields were lower could suffer further losses if rates continue to rise. When market yields rise, the prices of existing fixed-rate bonds generally fall.

For Nigeria, that global pressure arrives alongside a domestic financial system still adjusting to high interest rates and tight liquidity conditions. Higher global yields can influence the return investors demand from African sovereign debt, raising the potential cost of funding for governments and companies.
