Prime global rents tick up for the first time in a year as PCL hits seven-year low

There's been "a notable slowdown" in top-end rents around the world over the last quarter, says Knight Frank, as the agency's Prime Global Rental Index records its weakest annual growth rate since 2009.

No growth for average prime global rents in the year to September

Rents in prime cities around the world fell by an average of 1.1% in 2015 - a pretty significant contrast to the 2.5% growth posted in 2014.
