Fiscal & Monetary Policy: An Impossible Coordination?

Although monetary and fiscal policy objectives are considered distinct, there is a strong interaction between their actions. The increase in key rates aimed at ensuring price stability affects the cost of public debt and therefore budget balances.

Macroeconomic policies must therefore be coordinated to provide optimal responses to shocks.

A negotiation of the division of roles can call into question the credibility of monetary policy. But what would be the durability of an agreement setting this sharing?
