China's recent stimulus measures might help stabilise its property crisis, but investors should prepare for the end of the country's economic boom, according to Mark Delaney, Chief Investment Officer of AustralianSuper, which manages over AUD341bn (USD229bn). Speaking at a Bloomberg event, Delaney noted that China's annual growth rates of near 9% are a thing of the past, expecting future growth rates starting with four or five percent. China has introduced a series of support measures, including lowering borrowing costs on up to USD5.3tr in mortgages and easing down-payment requirements for second-home purchases. Delaney cautioned that housing slumps elsewhere have taken decades to resolve and that structural oversupply will significantly impact China.
