If you've got hard currency in cash, or in a dollar debit card, an economic recession is the time to spend it extremely carefully. Paying a close attention to the inflation rate should help you determine when to convert some of your foreign currency into your local currency for capital expenditures.
As the inflation rates show a pointer indicating that the devalued state of the local currency may start regaining its value, converting some of the hard currency to the local currency for your business investments and basic needs would give you a much higher valued deal.
