Abstract

The monetary policy operations of a Central Bank (CB) involve allocation decisions when purchasing assets and taking collateral. A green monetary policy aims to steer or tilt the allocation of assets and collateral towards low-carbon industries, to reduce the cost of capital for these sectors in comparison to high-carbon ones. Starting from a corporate bonds purchase program (e.g. CSPP) that follows a carbon-neutral monetary policy, we analyze how a shift in the CB portfolio allocation towards bonds issued by low-carbon companies can favor green firms in the market. Relying on optimal portfolio theory, we study how the CB might include the risk related to the environmental sustainability of firms in its balance sheet. In addition, we analyze the interactions between the neutral or green CB re-balancing policy and the evolutionary choice (i.e. by means of expo- nential replicator dynamics) of a population of firms that can decide to be green or not according to bonds borrowing cost.
