I have to admit I do not use my USB Swiss account to make interest as it is poor in comparison to many banks. I use as a solid savings base as the value of the Swiss CHF is pegged against gold not other currencies and therefore has very few downward trends. It is highly unlikely the value of my CHF will lose value in any form of market crash as whenever the market crashes investors always by gold.
Further more the Swiss government insures (underwrites) Swiss banks against collapse and therefore, although not a massive earner in % interest it is certainly as safe a place as I can put excess cash deposites.
I have absolutely no complaints about USB or the Swiss banking system. I never have any account details/balances sent via mail (although it is an option I can choose) as all the Swiss Banks offer internet banking and emailed statements so I see little point.
As for interfering with the mail, I cannot speak for the USA and the IRS, but the Inland Revenue, like anybody else in the UK cannot interfere with Her Majesty's Mail without either a court issued warrant or suspicion of prohibited materials contained therein, ie drugs, weapons, toxins etc. Should they do so any evidence obtained in such a way is inadmissible and would leave them open to prosecution under numerous laws relating to post, privacey etc. etc.
As it stands in the UK single deposites under £10,000 do not have to be notified to any policing body by any bank. A single deposite over £10,000 has to be unless the bank is satisfied as to the origins of the money. If they are satisfied then again they have no duty to report the transaction.
Also to be fair to the Swiss Banks (and I warned people on here regarding Credit Swiss in January) the Swiss banks even though exposed to the downturn in the US economy in the sub-prime market have not had to be bailed out like Northern Rock in England or Stern in the USA.
That said only a fool puts all his eggs (or money) in one basket.
