Abstract

The effectiveness of monetary policy in Ghana has been questionable with the advent of mobile money activities, which are gradually replacing some of the roles of commercial banks. This study investigates the effects of mobile money transactions on Ghanaian commercial banks' credit-to-deposit ratio and the effectiveness of the monetary policy rate in the era of mobile money services using ARDL techniques, Granger causality and impulse response functions.

The study reveals that Ghanaian commercial banks' credit-to-deposit ratio decreases with increased mobile money transactions, indicating a substitutability relationship. Banks' credit-to-deposit ratio is impacted by non-performing loans and asset returns, while the monetary policy rate has an insignificant impact. The results from the IRFs also showed that a positive shock to monetary policy reduces banks' credit-to-deposit ratio but increases mobile money transactions and non-performing loans. For policy implications, collaboration between commercial banks and mobile money service providers can be enhanced through interoperability services.

移动货币、信贷存款比和货币政策：来自加纳的经验。

随着移动支付活动的出现，加纳货币政策的有效性受到质疑，移动支付逐渐取代了商业银行的部分职能。本研究利用 ARDL 技术、格兰杰因果关系和脉冲响应函数，研究了移动货币交易对加纳商业银行贷存比的影响以及移动货币服务时代货币政策利率的有效性。研究发现，加纳商业银行的贷存比随着移动货币交易的增加而降低，这表明存在替代关系。银行的贷存比受不良贷款和资产回报的影响，而货币政策利率的影响不大。IRFs 的结果还显示，货币政策的正向冲击会降低银行的贷存比，但会增加移动支付交易和不良贷款。就政策影响而言，可以通过互操作性服务加强商业银行与移动支付服务提供商之间的合作。
