Iinterest Rates

can be drawn interest per month without affecting the exchange rate.

The fixed rate bonds often give you a higher interest rate, then a bank. Currently you can get 4 to 5 + per cent. Depends on the bond, but generally you can choose to ride on the interest or perceived. interest rate is guaranteed for the life of the bond, which is an average of 5 years. At the end, you get your full capital back.

You can sell your bonds at any time at market prices.
The risk is, a company may default on their obligations if they leave the company. Then you lose everything. So .... to be conservative, you can buy high-rated bonds or bonds guaranteed.

Why do not all buy bonds when you get a better interest rate? Firstly, because of the risk I mentioned above. Second, you can not necessarily have all the back principal before the end. If the price has dropped since you purchased, you can get market price, which will be less than what you paid for it.

You can get a better rate by committing your money for a period of time. Yes, some accounts do not pay interest monthly that you can nominate to pay into another account. I have it with Coventry Building Soc. (UK)
