How should I handle proving my 500k baht financial requirement for a visa application in Thailand?

before I applied, I mailed them asking how to deal with a situation similar to yours. the embassy clearly asked me to put all the money in a single bank saving account. When I replied asking if that would be an issue for the seasoning part (I had well over 500k but none of my 3 accounts could reach that quota) they said that I could also prove multiple accounts. I did as required, I submitted 2 bank accounts with one having over 500k (just few days prior my application) and another one with 300k. After I applied, the embassy required me further documents showing the money going from the company I worked with into my account (even tho I applied for soft powers) . Keep that in mind and good luck

The 500k (or whatever amount the embassy you apply at specifies) needs to be in instantly accessible bank accounts. Term deposits and brokerage accounts are not normally acceptable

Probably if you are well up 500k.

The 500k need to be in cash saving or available cash bank account ( no investment )

Multiple bank accounts can be accepted. Brokerage accounts are accepted by a few embassies in the USA. Where are you applying?
