Infrastructure projects and improved transparency could be key to improving investor sentiment in Jakarta moving forward, according to JLL.

The city was ranked 15th in Pricewaterhouse Coopers' list of the top Asia Pacific investment markets, which was included in the company's Emerging Trends in Real Estate 2019 report.

Speaking in response to the report, JLL Indonesia Head of Research James Taylor said there was reason to feel optimistic about the city's investment future.

"Jakarta is only going to increase in attractiveness in the eyes of investors over the next few years as doing business becomes easier, investment in infrastructure continues and transparency improves," he said.

"Logistics has been a favoured sector for investors for the last couple of years with international groups such as Logos aggressively growing their portfolio.

"In addition to logistics, the residential sector is of constant interest to investors who are able to build an investment case based on Indonesia’s attractive socio-economic fundamentals."

PWC used research from JLL to highlight the challenges facing Jakarta's market, which include office vacancy approaching 35 per cent in 2018.

Mr Taylor said while the sector was unlikely to undergo any major change in the short term, it was expected to level out beyond 2020.

"Occupancy levels and rents are likely to remain pressured in 2019 with some stability in subsequent years while demand is likely to remain healthy with technology and co-working companies leading the way in terms of space requirements," he said.

"The appetite for office development from both international and local groups remains extremely strong and a number of large scale long term projects are currently being planned."
