(Yicai) Sept. 25 -- China's two major mainland bourses, the Shanghai Stock Exchange and the Shenzhen Stock Exchange, will finish the first three quarters of this year attracting the largest initial public offerings in the world despite reduced listing proceeds, according to Deloitte.

From January to September, the SSE will be No. 1 in the world with 89 IPOs that raised CNY179.2 billion (USD24.5 billion), the multinational accounting firm wrote in a recent report. The SZSE will be No. 2 with 115 IPOs that garnered CNY133.3 billion.

The investing environment has become more challenging. The number of mainland IPOs dropped by 12 percent from a year ago while the total value of listings tallied CNY323.4 billion, down by 33 percent. Still, five of the world's top 10 IPOs landed on China's mainland, four on the SSE, and one on the SZSE. But even the big listings were smaller as the total financing of the top 10 declined by 54 percent.

The rest of this year is likely to be more quiet as large IPOs in China will be postponed based on the current situation, an insider from Deloitte said to Yicai. However, the SSE and the SZSE are likely to finish the year at the top unless some big names hurry to go public elsewhere in the world, the firm added.

In particular, the two bourses' technology-heavy arms have been welcoming a slew of new entrants this year. As of Sept. 23, some 97 firms have gone public on the SZSE’s ChiNext market, raising CNY111.1 billion, and 61 companies have done the same on the SSE's Star Market, bagging CNY138.1 billion.

Meanwhile, the Hong Kong market remained sluggish. The number and the value of new listings declined to a 10-year low as 44 new stocks started trading on the Hong Kong Stock Exchange in the nine months, raising HKD24.7 billion (USD3.2 billion).

The sum gives the HKEX the eighth spot in the global ranking so far and for the whole year, the bourse is expected to record the lowest financing over the past 11 years, Deloitte predicted.
