While the world of high, and not so high finance, is obsessing over the volatility of cryptos and recent painful losses for overlevered players who – much to the amazement of plain vanilla equity investors – were not bailed out by a magnanimous Fed (which, however, only rescues stock markets, not cryptos), things in China with its $54 trillion financial system, or more than double the size of assets across US commercial banks, are once again getting heated.

As Reuters reports, a large crowd of angry Chinese bank depositors faced off with police Sunday in the city of Zhengzhou, and many were injured as they were taken away, amid the freezing of their deposits by some rural-based banks.

The banks froze millions of dollars worth of deposits in April, telling customers they were upgrading their internal systems. The banks have not issued any communication on the matter since, depositors said.

According to Chinese media the frozen deposits across the various local banks could be worth up to $1.5 billion and authorities are investigating the three banks.
