The estimation is based on data for 24 SSA countries us<strong>in</strong>g fixed effects estimators. The dependent variable is bank spread. Constant term <strong>in</strong>cluded but not reported.<br />

Standard errors are reported <strong>in</strong> paren<strong>the</strong>ses. ***, **, and * <strong>in</strong>dicates statistical significance at <strong>the</strong> 1% 5% and 10% level respectively<br />

As banks pr<strong>of</strong>it <strong>in</strong>creases with tighten<strong>in</strong>g <strong>of</strong> monetary policy, <strong>the</strong> monetary policy <strong>in</strong>dicator is <strong>in</strong>teracted<br />

with bank credit risk, cash flow, fund<strong>in</strong>g strategy and market power to <strong>in</strong>vestigate monetary policy<br />

sensitivity <strong>of</strong> spreads. The result is presented <strong>in</strong> table 3. The sensitivity <strong>of</strong> spreads to monetary policy<br />

shock <strong>in</strong>creases as <strong>the</strong> cash flows <strong>of</strong> <strong>the</strong> bank <strong>in</strong>creases. The same results are obta<strong>in</strong>ed when bank fund<strong>in</strong>g<br />

strategy, credit risk and <strong>the</strong> bank market structure are used. All <strong>the</strong>se results are statistically significant at<br />

0.01 significance level. The economic significance <strong>of</strong> <strong>the</strong>se results is that <strong>the</strong> spread channel is much<br />

stronger among banks with higher market power and credit risk with a significant coefficient <strong>of</strong> 6 and 7<br />

percent respectively. The implication <strong>of</strong> this result is that <strong>the</strong> tighten<strong>in</strong>g <strong>of</strong> monetary policy <strong>in</strong>dicator is<br />

less effective with respect to banks with higher market power fund<strong>in</strong>g <strong>the</strong>ir <strong>in</strong>vestment from <strong>in</strong>ternal cash<br />

flow and experienc<strong>in</strong>g high credit risk.<br />
