Intentando resolver mis dudas, esto es lo que he encontrado en la páquina de FAQ (https://www.kbc.ie/help/faqs.aspx) con respecto a la retirada de fondos de la "Regular Saver Account" (que sería extrapolable a la retirada desde la "Extra Regular Saver Account" hacia la "Extra Current Account" asociada):
"Are any withdrawals permitted with this account?
Yes, withdrawals are available on demand. Withdrawals will be paid by EFT to the current account specified in the original application form. Changes to the nominated account must be confirmed to KBC in writing.
In the case of a Joint Account funded from two sources, the customer(s) must specify which account to transfer the funds to."
Y en el documento de "términos y condiciones":
"79.6 Regular Saver Accounts
79.6.1 Subject to Clause 84 below, you may withdraw funds from a regular saver account at any time."
Y en el FAQ, en cuanto a cerrar la "Regular Saver Account":
"What happens if I want to close my account early?
Upon Account closure the customer will receive the full amount of their savings and the interest accrued up to the closure date. This payment will be processed by Electronic Funds Transfer (EFT) to the funding account. No penalties or charges will apply."
Sin embargo en el documento de "términos y condiciones" dice lo siguiente con respecto a cerrar la "Extra Regular Saver Account":
"84.11.3 If you close your Extra Current Account in any given month, you will lose the benefits of the Extra Regular Saver (including without limitation any bonus interest rate applicable to the Account). Your Extra Regular Saver will become a standard KBC Regular Saver and the prevailing interest rate applicable to that account as set out in our then current Personal Deposit Rate Matrix will apply to your Account thereafter."
En resumen, no parece que haya limitaciones ni penalizaciones en el interés (esto último no lo tengo tan claro) a la hora de retirar dinero de la "Extra Regular Saver Account" hacia la "Extra Current Account".
