The subjunctive mood is used when the verb indicates a desire, intention, command, recommendation request, resolution, or advice. It is also used along with such words as advisable, better, desirable, and directive, essential, fitting, imperative, important, necessary, urge, urgent and vital.
Three things essential for the use of the command subjunctive mood is the mandatoriness of the situation wherein somebody gives a command and others have the need to follow it compulsorily. The command is always indicated in a relative clause starting with 'that ' and most importantly, the command is expressed through verb in a forthright base form of the verb called the bare infinitive.
EX: The court directed that the owner of the car pay the accident victim a sum of ten thousand rupees

directed: - The mandatory word.
that - the relative clause connector
pay -the bare infinitive.

1. In the given context, an announcement is not part of the mandatory word-list.
2. will try is not a bare infinitive.
3. The president is not commanding the economy to behave.
Therefore, no subjunctive mood is involved.
The take away: All command subjunctives will use 'that', but not all those, which use 'that', are subjunctives
