Spillover of Real Estate Loans on Banking Systemic Risk from a Dynamic Perspective
Firstly,the Credit Metrics model is initially employed to dynamically measure the credit risk of REL.Then,its influence on individual banks and its subsequent spillover on bank-ing systemic risk are evaluated under the double ΔCoVaR framework.Finally,the spillover is de-composed into direct and indirect components,allowing for an exploration on the transmission pathways of REL credit risk.The results for systemically important banks(SIB)reveal a consist-ent upward trend inREL credit risk over recent years,leading to a substantial spillover into the bankingsystem.Notably,the widespread defaults and the COVID-19 pandemic further intensified this spillover effect.Moreover,indirect spillover resulting from REL credit risk predominates o-ver direct spillover.Higher(lower)SIB exhibit larger indirect(direct)spillover.This suggests that higher SIB are more likely to cause chain reactions within the banking systemthrough their close business connections with other banks,indirectly exacerbating risk outbreaks due to their loan credit risks.Lower SIB provide loans to a few large clients,lack substantial risk mitigation against credit losses,thereby presenting a considerable direct risk to the stability of the banking system.
