This is why office space supply will be limited by end-2012

Only ~70k sq ft of office space will be for sale.

According to OCBC, looking ahead to the remainder of FY12, it is likely that a situation of limited office pipeline completion would ensue with only ~70k sq ft of office space slated for opening – a mixed use development in Upper Pickering St – which has been fully pre-leased to AGC.

Here's more from OCBC:

We see this dynamic continuing until mid 2013 when Asia Square T2 and The Metropolis T1&2 are slated for completion.

We believe the office rentals are likely to show a more subdued dip in 3Q12 after three consecutive quarters of declines since 3Q11. Over 2Q12, Grade A office rentals fell 4.7% QoQ to S$10.10 which cumulated in an 8.7% decline over three quarters.

Core CBD vacancies, however, showed a reversal from a rising trend in 2Q12 to register a 0.9 ppt dip to 8.4%. A similar picture was seen for island-wide vacancy rates which declined 0.9 ppt to 6.4% (end 2Q12) from
7.3% (end 1Q12). We expect a similar trend for vacancies in 3Q12 which would likely contribute to a muted rate of rental decline.
