3169 vs 9169 1. Should i trade in hkd or usd? Which currency is likely to grow stronger than sgd? 2. Should i be concern of the low AUM? What happen if fund close down? Will i get my money back?

3169/83169/9169 are the ticker symbols for Vanguard's Total China Index ETF. Just to let you know, Vanguard is planning to pull out of Hong Kong, so it may be better for you to find an alternative ETF from a different provider. You may be forced to liquidate should they close it down, and you could incur switching costs.

In terms of currency risk, the trading currency of an ETF does not matter, unless it is currency hedged. The currency risk you are exposed to is to the currency of the underlying assets in which the ETF invests into. In this case, that would be CNY (because China), not USD or HKD.

Instead, you should look at the liquidity of each of these tickers - a quick look tells me that 9169 is more actively traded. This could mean that there are more market participants and lower bid-ask spreads, which are beneficial to you especially in times of high volatility.

There is no difference between similar ETFs in HKD or USD. It doesn’t matter what currency your ETF is in as long as they invest in the same thing.

Yes, ETF with low AUM will likely have lower volume and a larger bid ask spread. If the ETF close down, the fund manager will liquidate all the investments and return the money to the investors. If it happens during stock market crash, they will have to liquidate at a loss.

“Have you ever seen a ETF that says its currency is dollars, while another version of the same product is labelled in pounds? That makes no difference whatsoever to your currency risk. What counts is your exposure to the currency the underlying securities trade in.” By justetf.
