Compaired with a few years ago, the risk of putting your money into a Turkish bank is now pretty low.
To reduced risks to a minimum, choose a well establish bank. (personally I don't know anyone who banks with Isbank, but doesn't necessarily mean anything). Don't transfer your money into lira until the rates are good, spread your money around. (most if not all banks guarantee a 50,000ytl return per person if the bank goes bust)
Time deposit accounts offer good interest rates (always talk directly to the bank, and if you have a substantial investment to make, you may get a preferential rate) as do the government bonds which are guaranteed return over a period of time, currently offering 20 - 23%. Remember to deduct taxes when making your calculations.
Time deposit...15% tax on your gains
Government bonds..10% tax on your gains.
Many people are nervous about investing their money out here, and rightly so, your hard earned cash is precious, but do your homework, look at the figures, talk to expats and take advise from them, then make your decision. Good luck
