Option

Treasury

Turkish: Opsiyon

Short definition

An option is the right, not the obligation, to buy (call) or sell (put) at a strike. Premium is paid up front; it floors or caps the bad scenario and leaves the good one open.

Detailed explanation

FX and rate options are used as budget caps and collars. A zero-cost collar sells upside to avoid paying premium; it is not a free hedge.

Accounting and margin follow delta. A sold (short) option is speculation or a collar; an unauthorised short enlarges the open book.

Why it matters for the CFO

On tenders, uncertain volume and asymmetric shocks a forward is too rigid; an option sells flexibility for premium.

How to read it

Premium is an insurance cost; charging it to EBITDA is hedge cost, not a separate “loss” KPI. Delta changes economic openness.
