THE inclusion of Chinese stocks in closely tracked MSCI share indexes is widely expected to draw tens of billions of dollars into the mainland market next month, but active fund managers’ conservative positions could mean inflows are much smaller.

Brokerages, including JPMorgan, Sinolink and Shenwan Hongyuan, predict around US$17 billion in foreign money will flow into China stocks during MSCI’s two-stage inclusion process, June 1 and Sept. 3, roughly in line with MSCI’s own estimates.

Goldman Sachs, BNP Paribas and Hong Kong-based asset manager CSOP expect inflows of about US$20 billion.

Such forecasts have stoked fears that a sudden gush of foreign money into the mainland’s roughly 230 big-caps via Hong Kong, the main channel for foreign investment in mainland shares, could sap a limited pool of offshore yuan in Hong Kong.

Underpinning these projections, however, is an expectation that active fund managers will look to immediately rebalance their portfolios to match the re-weighting of the benchmarks, a highly speculative assumption, according to some market participants.

“Those so-called educated guesses may not be accurate. Truth often rests with the minority,” said Wang Qi, a former head of China Index Research at MSCI who led consultation on the A-share inclusion at the U.S. index publisher.

Wang, now CEO of China-focused asset manager MegaTrust Investment (HK), forecasts the June 1 inclusion would bring in a mere US$1 billion in inflows, equivalent to “several minutes of trading” in China’s stock market.

Active fund managers account for more than 80 percent of the money tracking its indexes, according to MSCI.

Unlike passive index-tracking funds, which are obliged to buy China stocks to avoid tracking errors, active funds benchmarked against the indexes can stand pat as China’s weighting is so tiny, Wang said.

According to MSCI, US$1.9 trillion in assets track its emerging market benchmark. China’s stocks, or A shares, will represent a 0.78 percent weighting of this index after their initial inclusion. A shares will also account for 0.1 percent of ACWI, MSCI’s flagship global equity index followed by US$3.8 trillion of assets.

Caroline Yu Maurer, head of greater China Equities at BNP Paribas Asset Management, says she has no plans to make big moves around inclusion day.

“Our funds are relatively China-focused, with (Hong Kong-listed) H shares and A shares already exceeding 10 percent of our portfolio last year,” she said.

Research house TS Lombard said in a note that fund managers could easily adjust their portfolios by buying Hong Kong-listed stocks, meaning they would not need increased mainland exposure. Of the 230 or so A shares being added to the index, 49 have H-share listings.

Lyndon Chao, managing director of the Hong Kong-based Asia Securities Industry & Financial Markets Association (ASIFMA), also flags external risks such as North Korea and movements in U.S. bond yields as potential fund flow factors next month.

Despite the difficulties around forecasting inflows, regulators are leaving nothing to chance amid evidence brokerages in Hong Kong are hoarding offshore yuan ahead of an anticipated jam in the stock connect programs linking the mainland and Hong Kong.

The Hong Kong Monetary Authority has been preparing for months to ensure adequate yuan supply, while the People’s Bank of China announced a series of measures this month to support the offshore yuan market, after quadrupling the Stock Connect daily quota last month.
