Despite the political borders that remain, economic borders have blurred and in some places disappeared. For some people, investment abroad is prudent. In some countries, political leaders are so desperate for increased revenues that they raise taxes exorbitantly, impose exchange controls, and pass regulations that are designed to confiscate wealth in whatever way they can. By investing abroad, an investor can limit his exposure to such practices. For other people, investment opportunities that don't exist in their own country may be available abroad.
Real estate is a good example.
While real estate in Tokyo might be overpriced, the real estate in other countries might be very low and it might be possible to buy several properties that will result in significant future profits. Investing abroad increases your opportunities for making profits, while at the same time limiting your risk in any one market. As the world becomes smaller and the global marketplace expands, you owe it to yourself to find international investments that will satisfy your financial needs and long-term goals. While there are many investment opportunities abroad, one of the best places to consider is Switzerland. It has already been noted that the Swiss franc is the only remaining currency backed by gold, but that's just one reason for considering Switzerland for investment.
