Succinctly discuss the effectiveness of monetary policy in Nigeria

Monetary policy in Nigeria, primarily managed by the Central Bank of Nigeria (CBN), aims to achieve price stability and exchange rate stability. Its effectiveness is often constrained by structural rigidities in the economy, such as a large informal sector and supply-side bottlenecks, which limit the impact of interest rate adjustments and liquidity management. Furthermore, fiscal dominance and external shocks (like oil price fluctuations) can undermine the CBN's autonomy and policy transmission mechanisms, making it challenging to consistently achieve desired economic growth and inflation targets. While it can influence short-term liquidity and exchange rates, its long-term impact on sustainable growth is often mitigated by these underlying issues.
