The Green Street Commercial Property Price Index held steady across all asset types in April. The firm's all-property index is up just 0.2% this year, in stark juxtaposition to last year's 24% increase. 

"Commercial property prices are not going up anymore, but for the most part, they're not going down either," said Peter Rothemund, Co-Head of Strategic Research at Green Street. "That's about as good as one could hope for in this environment, and a lot better than bonds and stocks, which have both lost about 10% in value as interest rates have increased."

Green Street's index is a time series of unleveraged US commercial property values that captures the prices at which commercial real estate transactions are currently being negotiated and contracted. The firm says the index is differentiated by its emphasis on high-quality properties and its ability to capture changes in the aggregate value of the commercial property sector.
