This study examines the factors influencing inflation stability in Nigeria from 2011Q1 to 2023Q1. We employ an ARDL model to assess the impact of monetary policy rate, money supply, crude oil price, GDP growth, and government budget deficit on inflation. Our findings reveal that broad money and fiscal deficit exert a positive and statistically significant influence on inflation in both the short and long run. Interestingly, monetary policy rate only affects inflation in the short term. These results suggest that Nigerian policymakers should prioritize managing broad money and fiscal deficits to achieve long-term inflation stability.

This paper investigates the impact of monetary policy on the performance of deposit money banks in Nigeria, using monthly data series spanning the period 2008 to 2023. Total private sector credit of deposit money banks was used to proxy the performance of deposit money banks while money supply, monetary policy rate, cash reserve ratio, and maximum interest rate were used as proxies for monetary policy. The Ex-post Facto research design was adopted in this study. Data on total private sector credit of deposit money banks, money supply, monetary policy rate, cash reserve ratio, and maximum interest rate were obtained from the Central Bank of Nigeria (CBN) Statistical bulletin. The hypotheses of this paper were tested using the Autoregressive Distributed Lag statistics. The findings disclosed that total private sector credit of deposit money banks has a significant relationship with money supply and maximum interest rate while cash reserve ratio and monetary policy rate has an insignificant relationship with total private sector credit of deposit money banks. The researchers recommended among other things that the monetary authorities should consider policies that enhance liquidity within the banking system. This can be achieved through open market operations, reducing the reserve requirements, or other mechanisms that increase the availability of funds in the economy as the money supply was found to be statistically significant. Also, it is crucial for monetary authorities to monitor and adjust the maximum interest rates to ensure they remain conducive to deposit growth. High lending rates may discourage borrowing and subsequently reduce deposits, while more favorable rates could encourage economic activity and deposit inflows.

Excessive volatility in financial markets can disrupt economic activity, affect investor and consumer confidence, and potentially lead to financial crises in an economy. Due to this backdrop, this study examined the link between asset class volatility and the output gap in Nigeria. The asset classes were categorized into stock, crude, gold, and bitcoin. The study adopted the GARCH and Bayesian VAR approach and found that all share index has an initial negative impulse with output gap while other asset classes have a positive impulse on output gap. The outcome of this study revealed to both policymakers and economists the potential risks and vulnerabilities of asset class volatility in the economy. Based on this result, recommendations are made amongst which is the strengthening of the Nigerian stock market to help with the inflationary pressures this is because the Nigerian stock market hurt the output gap also, the government should prioritize investing in crude, gold, and bitcoin to push the actual output to full capacity, which brings about employment.

In an effort to provide policy recommendations for Nigeria's transition to full-fledged inflation targeting, this study examines Ghana's monetary policy frameworks (monetary aggregates targeting and inflation targeting) using ARDL bounds test for cointegration and Error Correction Mechanism (ECM) on annual time series data spanning 1965 to 2022 obtained from the Bank of Ghana database and the World Bank database on World Development Indicators. The results demonstrate that monetary aggregates targeting has not been successful in both the short-run and long-run periods in moderating and stabilizing inflation; however, inflation moderated under inflation targeting in both the short run and the long term. This indicates that inflation targeting proves to be a superior monetary policy framework for inflation control.

The rise of privately issued digital currencies, which primarily serve as alternative investment assets poses a challenge to the traditional financial instruments traded in the financial market. This study examines the dynamic relationship between the major privately issued digital currency (Bitcoin) and two financial market securities in Nigeria. The paper employed Vector Autoregressive (VAR) model and presents three relevant findings. First, the impulse response function indicates the absence of a significant response of the Nigerian financial market to shocks emanating from the Bitcoin market, implying lower connectedness between the two markets. Secondly, the outcome of the variance decomposition reveals a lower contribution of Bitcoin to changes in stock prices and treasury bills, however, stock prices and treasury bills contributed higher impact to each other compared to the contribution of Bitcoin. Thirdly, a weak bi-directional causality between the Bitcoin and treasury bills was observed and a uni-directional causality running from treasury bills and stocks, implying the existence of portfolio rebalancing from the fixed income to the equities market. Despite the weak connection between digital currency and the financial market, the paper recommends that the Central Bank of Nigeria and the Securities and Exchange Commission should maintain monitoring the development of crypto exchanges and continue reviewing the existing policy restricting cryptocurrency transactions through banks to avoid its unsavoury effects.

The paper is motivated by the growth of the electronic payments system and its relevance in enhancing the banking industry's earnings. Consequently, the paper examines the causal relationship between the electronic payments system and the banking industry's returns in Nigeria. The paper offers some important contributions to the literature involving the use of an approach that allows for data-driven identification of the change points in the electronic payments system and the banking industry's returns nexus. The paper discovered three important findings. First, the causal relationship between the electronic payments system and the banking industry's returns in Nigeria changes with time changes. Second, there is evidence of causality between the electronic payments system and returns on assets and equity, however, the causality was more evident under the recursive window. Third, the causal relationship was more evident in some specific periods such as 2020Q4, all quarters of 2015 to 2016, and 2020 to the end of 2023. The paper recommends that policymakers should revisit and reinvigorate the specific cashless policies instituted in 2012-2016 that aided higher returns to the banking industry. Similarly, the Central Bank of Nigeria and other banking industry players should intensify efforts to encourage the use of electronic payments due to their usefulness and ability to enhance the banking industry's earnings.

The sensitive nature of interest rate has spurred empirical interests on the factors that determine it. This paper examined the joint impact of exchange rate and foreign direct investment inflows on interest rate in Nigeria over the period from 1981-2022. The study made use of the auto regressive distributed lag (ARDL) bounds test and results of findings reveal that in both the short-run and the long-run the impact of the interaction between FDI inflows and exchange rate on real interest rate was negative and significant. Also, while credit to the private sector was found to have significant positive impact on real interest rate in both the time horizons, the impact of consumer price index was negative only in the short. Oil revenue was found to impact positively on real interest rate only in the long-run, but the impact of broad money supply was negative and significant in both the short-run and the long-run. The study suggests that policies to regulate domestic interest rate should focus on joint regulation of both exchange rate and FDI inflows and this requires a synergy between monetary and fiscal policies.

The Paper investigates the elasticity of substitution between foreign direct investment (FDI) and private domestic investment on the external reserves of some selected 14 African countries. To achieve the objective of the best substitutability of investment suitable for Africa, using data on gross fixed capital formation as a proxy for private domestic investment, inflation, external reserves, and foreign direct investment. From the Empirical literature reviewed, studies on the substitutability of investments in external reserves in Africa have not yet been addressed. The Dynamic General Methods of Moments (DGMM) was employed for the analysis since the African countries are more than the scope of the study which ranges from 2010 to 2022. The results show that foreign direct investment is preferred to private domestic investment in Africa. Additionally, the elasticity of substitution from FDI to domestic private investment was found to be stronger and more elastic than the contrary. Therefore, the study recommends that African countries should focus on strengthening fixed assets to create more revenue from additional fixed assets which would impact more on the external reserves of Africa, by attracting foreigners.
