ZURICH, Oct 15 (Reuters) - UBS must review and

improve its plans for an emergency to increase its options

should there be a risk of insolvency, Swiss financial markets

regulator FINMA said on Tuesday.

FINMA said it had suspended the annual assessment of UBS's

emergency plans while Switzerland's last globally systemically

important bank reviews its approach.

"Based on the experience of the Credit Suisse crisis,

additional options for action are required to further strengthen

crisis preparations and resolution planning for systemically

important banks," FINMA said in a statement.
