My broker said that he will close my account as I have no activity for a year. Is this common?

Phillip Securities also charges an indirect inactivity fee (still better than closing):

S$16.05 per quarter

(Quarterly trading activity is assessed at Mar, Jun, Sep, and Dec month end)

Waiver Condition: At least 1 trade per quarter for the account​​​

Hi anon,

This depends on the broker, but we don't close inactive accounts within a year.

Your shares, if residing on CDP, will stay there.

If they were held in custodian by the broker, you will get a certificate or similar to transfer out the shares to another broker.
