How to calculate total assets on SBI securities

  • December 29, 2025

Hi,

I have spent several hours trying to calculate the total value of my assets on SBI securities and still failed to reconcile the numbers, so I would appreciate if anybody could point me in the right direction.

I have:

  1. investment funds, domestic and foreign stocks in the NISA
  2. foreign stocks in 特定口座源泉徴収あり outside the NISA
  3. as a result of foreign stock transactions, some deposits in foreign currencies.

One would expect the my asset page (My資産) to provide an accurate representation of the assets but it actually shows an evaluation *much* lower than that of just the NISA balance alone, which in itself seems bizarre, but… OK.

The JPY cash deposit shows a different balance depending on whether you check the my asset page or the foreign stock one. Or maybe there is a separate JPY deposit account dedicated to the proceeding of sales from foreign stock?

Also, the my asset page does not seem to show all currencies (E.G. it does not show Hong Kong Dollars).

Does anybody have any experience with this, and could point me in the right direction, maybe?

Thanks for any pointers.
