Stocks VS Bank deposit

Stocks

The long-term average annual return for the U.S. stock market, typically measured by theS&P 500, is approximately 10% before inflation. When adjusted for inflation, the real return is generally closer to 6%–7% per year. These figures represent long-term averages; annual performance frequently fluctuates significantly above or below this average.

Bank deposit

Although average annual return for the U.S. bank deposit is much lower, I know banks in other countries which give annual return similar to US stocks, something around 9-10% annually. I am talking about legitimate banks with years of history, not some scam. Some fixed amount is even guaranteed by governments, so in case something happens with the bank, government covers partially.

Considering these, has anyone thought of putting safe bank deposits internationally to get fixed guaranteed annual return rather than volatile stocks market and forget about market's ups and downs?

I want to emphasize that the deposit is made in other currencies, and you have some risk of exchange rate volatility. However, for my case, there was no major change for the last decade, and even the rate has decreased in last year giving more benefit in terms of USD.
