Usuary is one of the biggest curse

For the wrong-doing of the Jews, We made unlawful for them certain good foods which has been lawful for them, and for their hindering many from Allâh's Way;

And for their charging Riba (usury or interest) while they were forbidden from it, and for their devouring of the properties of the people by false means. We have prepared, for the disbelievers among them, a painful punishment.

An-Nisa 160-161

Islam is the only religion which ensures the human rights of its followers .Islam forbids from usury as it thrives the exploitation of the poor and needy.Islam has given detailed and evergreen guidelines about financial matters.
In the above verses the point to ponder is that usury and eating the properties of others are such big crimes that it earned the Jews the wrath of Allah.

An interesting point is that from this verse we can conclude that Jews were the first ones to create this cursed financial system and this banking system is also the product of Jewish minds.

We should avoid taking interest from this current banking system.Although some banks are doing he business of Islamic banking but i don't think that it is free of doubts either.Saving accounts are particularly highly questionable,so try to avoid it.
I saw a decree (fatwa) of a cleric of Minhaj Ul Quran ,(the organization of Dr. Tahir Ul Qadri) that p.l.s accounts are halal as they deal on the basis of profit and loss instead of fixed deposit.This decree seems to be somewhat satisfactory that accounts dealing on profit-loss basis are permissible.
