Office rents are expected to move downwards further before bottoming out next year, according to estate agents.
The large supply, estimated at more than 10 million square feet for last year and this year, has forced rents down and the decline has been aggravated by the weakened economic environment.
According to FPDSavills, grade A office space rents fell by 33.4 per cent last year and are down by 34.3 per cent from their peak in the third quarter of 1997.
Effective rents, taking into account the impact of longer rent-free periods, have slumped by 53.7 per cent from the peak.
The fall in rents accelerated last year amid the volatile and high interest rate environment with more companies reporting layoffs and bankruptcies.
Landlords offer all kinds of incentives, including lower rents and rent-free periods of as much as 15 months for a three-year lease.
