Singapore's government, not its private sector, thus sits on one of the world's largest pools of foreign assets.

A pool so large that Singapore's government refuses to disclose how much it has, or release Singapore's Net International Investment details
Emulating the Singapore model -- taken literally -- would mean that the U.S. and the Euro area would need to start intervening in the fx market to the tune of 10% of GDP or more (a massive increase in the state's presence in the market)
And I would think the general equilibrium problems of all the world trying to be corporate tax haven and the entire world trying to maintain undervalued exchange rates through extensive state intervention in the fx market would be fairly obvious.
There is a plausible case that Signapore's state added close to $100b (counting reserves shifted over to the GIC) to its foreign assets last year.

Doesn't map to my image of a small but effective state.
