Understanding the CMBX Index

In the world of commercial real estate finance, understanding the various instruments available for investment and risk management is crucial. Two key components of this landscape are the CMBX Index and CMBS (Commercial Mortgage-Backed Securities). This blog aims to demystify these terms, explaining what they are, how they function, and their significance in the market.
