Why are interest rates on saving accounts so low in USA and Europe?
There is really much simpler explanation for the interest rate differences in different countries. It is the interest rate arbitrage. It is a very well explored economic concept, so you can look it up on the Internet, in case you want to know more. 1) Interest rates for the same currency in different countries Basically, as one smart person here pointed out, there is only one price of money in free market economy. It happens, because investors can move their money unrestrictedly anywhere in the World to capitalize on the local interest rates advantage. For instance, if I can take a loan in the USA at 3-4% annual interest and receive 5-6% annual income on my dollar deposit in Russia, I would take a loan in the US and open a deposit in Russia to enjoy a risk free interest rate differential income of 2% (5-6% - 3-4% ~ 2%). So, would any reasonable person. However, in real World very few banks in Russia or anywhere would pay you an an interest rate higher than it can borrow money at. It'd probably lose money if it'd do so. Anyways, the difference between the risk free rate and interest rate on the dollar deposit can be attributed to the risk premium of this particular bank. The higher expected return, the greater risk premium. If there is a positive difference in the interest rates on the dollar deposits in different countries, it will almost entirely accounted for the risk premium. It is generally much riskier to keep money in, say Russian bank, than American. That's why investors want greater return on their dollar deposits in Russian banks than in American. Of course, if you'd want to park your USD in Russian bank you'd also have to consider transaction costs. So, as you may have already guessed, there is no free lunch. 2) Interest rates in different currencies for different countries If we are talking about the interest rates in different sovereign currencies, it is a somewhat similar concept, only there is more risk if you keep money in local currency (risk premium is much higher). Probably, the biggest component of this risk is inflation (that is only attributed to the prices in local currency). For that reason, current interest rates on deposits in Russian Rubles are at 10-12%, but only 1-3% in the US Dollars. An economic concept that discusses this phenomenon in great detail is Interest Rate Parity.  Hope this was helpful. P.S. It doesn't look quite realistic that you can get an 8% annual income for USD deposit in Russia with the interest rates in the U.S. being at 1-2%. At present moment, a 30-year mortgage annual interest rate in the US is at ~2-3% and an annual interest rates for dollar deposits in Sberbank (one of the safest Russian banks = very little risk premium) is at 1-3%. So, arbitrage is impossible.
