Where do you store your emergency savings (Liquid) and be sure of the bank security?

Avoid saving credit cards details on shopping portal. My friends have experienced fraudulent transactions due to that. Personally I think the local banks’ security can still be trusted, just be careful when clicking links and email. So as of now, i would still choose to keep the emergency funds in banks, but if you wish, can consider fixed deposits. Open a few with different expiry so that you won’t forfeit all the interest if ever you have to access part of the pool.

Don't think bank security is at fault for fraudulent online transactions. More likely due to phishing website or other scam sites. On your bank and credit card accounts, you could disable overseas transactions.
