I have been wondering this too. If it's any consolation, you aren't alone if they fold.
Under the current implicit system:
- There are no upfront assurances that government will bail the bank out;
- In an implicit scheme, compensation of depositors is funded from taxpayer funds, and depends on the ability of government to fund such payouts at the time;
- Even if government decides to compensate depositors of a failed bank it can be a lengthy process to actually execute the payments;
- Compensation that depends on government funding at the time of failure tends to be pro-cyclical because support is usually required at a time when the economy and the financial system may already be vulnerable as a result of wide-spread banking distress
