Looks like someone shared this on Citibank SG's Facebook page, and it has provided the following response:

Maybe Citi is in trouble.....it has already offloaded quite a few of its commerical banking assets in four countries to UOB in recent times. Better cash out while you still can.

Purchase of commercial banking units comes as region's digital battle heats up

Is Citibank infested by CECAs?

The message looks fake leh

It only mentioned cash withdrawals, might this requirement apply to cashier's orders as well? Hmmm

Scammers will not be adversely affected, for they can just ask for $199,999.99 instead 😛

Need to give notice 就 give notice, 没有办法的 :(

Heng ah I stash away my savings in a Khong Guan biscuit tin, so this is not a problem for me

😲😲😲

The fuck is this shit? Is Citi anticipating a potential bank run and therefore taking countermeasures against it?
