Ghana’s Central Bank Pays $1.4 Billion in Interest to Keep Inflation at 3.4%

Why It Matters

The Ghana case illustrates a broader dilemma for emerging markets: aggressive monetary tightening can safeguard price stability but may impose a hidden fiscal burden on central banks, especially when sterilisation tools are used at scale. When interest costs consume a large share of a central bank’s income, the institution’s balance sheet becomes vulnerable, potentially limiting its ability to respond to future shocks. Moreover, the profit transfer to commercial banks raises concerns about financial sector incentives and the allocation of scarce capital in economies that still need robust investment to sustain growth. For policymakers across the region, Ghana’s experience signals the need to design liquidity‑management frameworks that balance inflation control with fiscal prudence. It also underscores the importance of transparent reporting and coordination between monetary and fiscal authorities, especially under IMF‑backed programmes where fiscal space is already constrained.

Key Takeaways

• Bank of Ghana paid GH¢16.73 bn ($1.4 bn) in interest to commercial banks in 2025.
• Outstanding OMO liabilities rose to GH¢93.56 bn ($7.8 bn), nearly tripling in one year.
• Interest expense represented about 75% of the central bank’s operating income before costs.
• Inflation fell from 54.1% in Dec 2022 to 3.4% by April 2026, while the cedi stabilised.
• Commercial banks earned roughly GH¢15 bn in profit during the same period.

Pulse Analysis

Ghana’s $1.4 billion interest bill is a cautionary tale for emerging markets that rely heavily on OMO sterilisation. Historically, central banks in the region have used similar tools to curb inflation without incurring such a massive fiscal hit. The key difference in Ghana is the scale: a three‑fold increase in OMO liabilities within a year suggests that excess liquidity has been persistent, perhaps reflecting structural financing gaps in the private sector. If the central bank continues to fund these operations at near‑policy rates, the fiscal drag could force a re‑pricing of risk for the entire banking system, potentially tightening credit conditions just as the economy needs more investment.

Comparatively, other African central banks have begun to diversify liquidity‑absorption mechanisms, using reverse repos, foreign‑exchange swaps, or targeted lending facilities that carry lower interest costs. Ghana could adopt a similar mix, reducing reliance on high‑rate BoG bills. Additionally, improving the depth of domestic capital markets would give the government alternative avenues to manage liquidity without over‑burdening the central bank.

Finally, the profit windfall for commercial banks raises governance questions. While banks benefit from higher yields, the broader economy may suffer if the central bank’s balance sheet weakens. A coordinated policy response—perhaps involving a modest increase in the central bank’s capital base or a temporary fiscal offset—could preserve monetary credibility while protecting fiscal space. The outcome will shape investor perception of Ghana’s macro‑policy credibility and could set a precedent for how other emerging markets balance the twin imperatives of price stability and sustainable financing.
