(Yicai Global) March 6 -- A new supply peak will expose office building rents in Shanghai and Shenzhen to downward pressure this year, while overall demand in the Asia Pacific region will remain stable, US commercial real estate services giant CBRE Group Inc. has predicted in a report.

The supply space of Grade A office building in the Asia Pacific region will exceed 5.5 million square meters this year, up 26 percent over last year to hit a new high, 70 percent of which will come from India and China, CBRE said in it recently-released 2018 Asia Pacific Real Estate Market Outlook.

A spike in supply is exerting downward pressure on Shanghai and Shenzhen office building rents, but Guangzhou's office leases will lead the rise in China while those in Beijing will go up moderately. Globally, first-rate office building rents in Japan, Singapore and Australia's Sydney and Melbourne will also see active growth.
