I'm a UK citizen running a business in Taiwan. Unfortunately even several years later I'm still dependent on cash from the UK side of the business.
In the UK I've got some property which I rent out. I've also set up a relatively small permanent portfolio, like this
NameSymbolGain %
ETFS METAL SECURITIES LD ETFS PHYSICAL GOLD £PHGP17.75%
ISHARES II PLC ISHARES FTSE UK ALL STKS GILTIGLT11.87%
DB X-TRACKERS DB X-TRACKERS £ MONEY MKT ETF CAPXGBP1.77%
DB X-TRACKERS DB X-TRACKERS FTSE ALL-SHARE ETFXASX2.66%
I've had this since 19/10/2010. It's +8.52% up since then. Annualised the return is about 4.78%
I.e. it's not too bad. One mistake I made was using the XGBP fund which is basically money markets - I'd have got a better return in a building society.
Now since I'm based in Taiwan I worry that my assets are too UK based. The UK is a relatively small economy and there are clearly issues with the banks there. Also the shares I've got are with HSBC in the UK. They are also held in a nominee account. The first £85000 in shares owned via HSBC are covered by deposit insurance. Of course in a meltdown the deposit insurance may not pay out. And anything above that is not covered. Normally worrying about HSBC going under would be paranoia, but right now I'm not sure the risks are negligible, even if they are rather small.
I've got an account with Fasttrade.co.uk where I have a CREST sponsored account. CREST sponsored accounts mean that the shares are not in a nominee account but you are the beneficial owner. So if the sponsor, e.g. Fastrade, goes under you could theoretically transfer the shares to a different broker and sell them. So if I want to expand the portfolio that is one option.
Still I worry about currency risks - aka the GBP crashing or more likely slowly devaluing versus the TWD. I've done some research into a Permanent Portfolio in Taiwan, but I've still got no idea how to do this in practice.
The other option would be do Permanent Portfolios in other currencies. This would diversify the risk. Still Harry Browne apparently thought that you should do your portfolio in your own currency. Then again I'm not really sure that the GBP is my currency - I've got no plan to go back to the UK. In fact if the balloon goes up financially speaking I'd rather head pretty much anywhere else than the UK. The reason I've got assets there is that my English is a hell of lot better than my Chinese so I feel like I've got a better idea of the risks.
There's an argument for USD because the US is a remarkably resilient place over the long term, and a PP is relatively easy to implement there - e.g. SPY, TLT, GLD, SHY as mentioned here.

In fact you can hold US ETFS in a UK CREST account - there's something called a CDI. Of course I could just fly to the US and set up the portfolio the old fashioned way if I didn't trust the CDI mechanism to cope in the middle of an implosion of the UK economy.The strategy was developed before the time of ETFs. While using ETFs shifts the risks involved, their prevalence and accessibility make it easy to implement the Permanent Portfolio. The above baseline performance history was compiled using an ETF based strategy, simply holding 25% in each; SPY, TLT, GLD, SHY.
I've also wondered about Australia, Switzerland, etc. That way I'm still somewhat diversified and insulated from a GBP crash.
I think the basic problem is that Harry Browne was a purely American investor because he had no intention of moving elsewhere. That was fine for him, but a lot of people now have much more complex lives - i.e. we work in multiple countries over our careers and intend to end up in the long run in perhaps another one. Perhaps you could argue that diversifying across currencies is a more Harry Browne approach to the problem of currency risk than trying to predict the future.
