When applying for a soft power DTV would a statement from a brokerage account (JP Morgan) work or does it need to be a savings account or checking account?

Hi all,

Regarding the marriage visa B400k bank account balance requirement, does anyone know if this can be satisfied by a CD/time deposit account? Or does the money strictly have to be in a traditional checking or savings account?

Krungsri appears to have a very favorable 4yr CD rate that's also available to foreigners, so I'd much prefer my money not excessively depreciate in value if it has to sit somewhere for this.

Thanks in advance!
