The Achilles’ Heel of Cardoso’s Monetary Policy: Orthodoxy Without Transmission

The Central Bank of Nigeria under Olayemi Cardoso came into office with a clear mandate: stop the bleeding. After nearly a decade of administrative controls, multiple exchange rates, and a balance sheet stretched by development finance, the new team chose the oldest playbook in central banking — orthodoxy. Unify the FX windows. Let the naira find a market price. Raise rates aggressively to tame inflation. Pull back from quasi-fiscal lending. Speak to the market in the language of targets and credibility.

On paper, it is the right reset. It mirrors the path that earned central bankers like Amando Tetangco and Mark Carney global recognition in 2013: restore discipline, anchor expectations, and let price signals work again. For a country that had lost investor confidence and was struggling with FX backlogs and arbitrage, the move was overdue. The beauty of the Cardoso approach is its clarity. One rate, one message, one objective. After years of opacity, markets and portfolio investors finally have a reference point, yet that clarity immediately runs into Nigeria’s deeper structural problem.
When The Banker named its 2013 Central Bankers of the Year, the global story was not just about low inflation. It was about governors who invented new tools under pressure, protected stability, and linked monetary policy to real economies. Turkey’s Erdem Basci built macroprudential instruments to manage hot money without capital controls. Canada’s Mark Carney steered a crisis-tested system and then shaped global rules. The Philippines’ Amando Tetangco used credibility to support growth. Saudi Arabia’s Fahad Al-Mubarak unlocked housing and credit. Angola’s José Massano built transmission channels in a young financial system. Their common thread was adaptation.

Measured against that standard, Nigeria’s last two CBN administrations present two very different models, each with its own beauty and its own drawbacks.

The tenure of Godwin Emefiele from 2014 to 2023 was defined by administrative intervention and development finance. The CBN operated multiple exchange rates, ran large intervention funds in agriculture and manufacturing, used CRR debits and special schemes to direct liquidity, and often acted as both monetary authority and quasi-fiscal agent. The logic was to keep credit flowing and protect output in the face of oil shocks, recession, and COVID. In that sense it echoed what some 2013 winners tried to do: Basci managing volatile flows without shutting the economy, Massano forcing credit through reluctant banks, Al-Mubarak linking policy to housing and jobs. The beauty of this approach was its ambition and reach. Anchor Borrowers and other interventions did get money to farms and SMEs when commercial banks would not. In a context of fiscal dominance and fragile FX earnings, the CBN tried to be the engine.

The drawback was that the instruments weakened the very foundations they were meant to protect. Multiple FX rates created arbitrage and rent-seeking. Heavy intervention blurred the line between central banking and fiscal policy. Inflation stayed high and the policy rate lost its signaling power because transmission was bypassed rather than repaired. Like Basci warned, without a rich set of market-based tools, the system became dependent on the CBN’s balance sheet, and credibility eroded over time.

Since September 2023, the administration of Olayemi Cardoso has taken a sharp turn toward orthodoxy. The route has been FX unification, clearing of FX backlogs, aggressive rate hikes to fight inflation, tighter OMO and CRR, and a retreat from direct development lending. Communication has also shifted to MPC guidance and inflation-targeting language. This model aligns more closely with what earned Tetangco and Carney recognition in 2013: use price stability to create space for growth, and use clear communication to anchor expectations. The beauty here is discipline and clarity. A single FX window reduces distortions. Higher rates have helped attract portfolio inflows and slow inflation expectations. The CBN is once again speaking in a language markets understand, and that matters for investor confidence.

But the adjustment has also been costly. Credit to the real sector has tightened at the same time fiscal policy is consolidating. There is the time lag that Tetangco himself highlighted: policy hits financial markets first, and only later reaches households and businesses. In an economy that did not get a large stimulus buffer in the last crisis, tight money risks slowing growth and jobs without yet delivering single-digit inflation. And unlike Turkey under Basci, Nigeria has not yet built the alternative macroprudential tools, reserve mechanisms, or deep interbank markets that allow a central bank to manage volatility without relying only on the rate.

Comparing the two to the 2013 winners clarifies the gap. Basci succeeded because he paired orthodoxy with innovation: rate corridors and reserve options that managed inflows without closing the economy. Massano succeeded because he built the pipes: committees, reference rates, and laws that made the kwanza matter. Tetangco succeeded because four years of hitting inflation targets gave him credibility to support growth. Carney succeeded because he linked stability to institutions and global rules. Al-Mubarak succeeded because he unlocked a market.

Nigeria’s challenge now is not to choose between intervention and orthodoxy, but to layer them. The discipline of the current model is necessary, but it will not be enough on its own. What is needed are Basci-style instruments to manage capital flow volatility without constant rate shocks. What is needed are Massano-style reforms to strengthen transmission so that policy actually moves from the CBN to banks to people. What is needed are Tetangco-style consistency and Al-Mubarak-style market development to ensure inclusion is not sacrificed for stability.

In short, an “award-winning” Nigerian model would keep the credibility being rebuilt today, add the innovation that was attempted in the last decade, and focus on building institutions that make monetary policy work in the real economy. The beauty of stability is real, but it becomes durable only when it is matched with tools, transmission, and inclusion. That was the lesson from 2013, and it remains the task for Nigeria in 2026.
