Abstract
This paper examines the relationship between monetary policy and financial stability through a “leaning against the wind” strategy in the context of an emerging economy. We estimate a Dynamic Stochastic General Equilibrium (DSGE) model with financial frictions tailored to Tunisia. A standard Taylor rule is compared with an augmented version that includes credit growth as a financial variable. The results show that when the Central Bank of Tunisia assigns a moderate weight (0.10) to financial stability, output volatility declines slightly. When the weight increases to 0.50, giving equal importance to financial stability and output stabilisation, the policy significantly reduces fluctuations in both credit and output, but at the cost of greater inflation variability. This trade-off highlights the limits of conventional monetary policy and indicates the need for complementary macroprudential tools to support both price and financial stability.
