UBS presents a semi-bear case:
Commencements of 195k in 2017 & 175k in 2018 Q1-17 dwelling commencements fell more than expected, down 11% q/q & 19% y/y, the ~largest fall since the GFC, to 202k a.r., the lowest since Q2-14 (albeit likely partly weather related). Q1 was hit by a slump of private medium-density (-15% q/q, -29% y/y), but private houses also fell (-8% q/q, -9% y/y, Figure 2).
More recent approvals also surprisingly dropped 20% y/y to 197k a.r. in May-17, the ~lowest since 2014, well below a ~240k trend in recent years (Figure 3). Highrises of 4+storeys are the key drag (Figure 4). Indeed, amid anecdotes of developer caution and tighter lending/credit conditions (and some capacity constraints given a ~record level of activity), the approvals-to-commencements ratio retraced sharply to well below a ‘break-even’ level (i.e. 1) and also under its average (Figure 5).
