Traditionally, risks are defined as the ratio between free funds and non-free funds.

Thus, we can express the risks of the banking sector as the ratio between M2 and the monetary base.

For convenience, I use the amount of mandatory reserves and cash as the monetary base.

I got it as shown in the picture below.

Figure 1.

Although the risks stopped their aggressive growth in the 25th year, they continue to grow.

I think this is a reason for the Central Bank to increase the required reserves for banks.
