I recently transferred in funds via ACH and converted them to another currency. Why am I unable to withdraw the converted funds?

INITIATE ACH TRANSFER

Automated Clearing House (ACH) deposits/withdrawals may be made to your IBKR account from and to your bank. ACH transfers are only available for US Dollar deposits from an account held in your name at a U.S. bank that allows ACH deposits. To fund an account in USD from a bank located outside of the U.S. you can use a Bank Wire, please see:…

EFT requests received by 09:30 ET, will be credited to your account after five business days under normal circumstances. 

Funds may be withdrawn after the five day credit hold. If funds are withdrawn to a bank other than the originating bank/instruction, a 66-business-day withdrawal hold period will be applied…

It depends upon the method of deposit. In the case of deposits made via ACH, interest accrues from the date the deposit arrives through the four-business day credit hold period after which it is credited to the account. In the case of check deposits (other than Bank Checks), no interest is accrued during the credit hold period. Bank Checks and wire transfers are credited to the account effective upon receipt and are therefore not subject to any credit hold…

The credit hold period on check deposits depends on the check currency:

• USD Checks: Funds are credited to the account after a 7 business day credit hold, with the exception of Bank Checks, which are credited immediately.
• HKD Checks: The Withdrawal Hold Period is 3 business days (you may withdraw funds after 3 business days)…
