The fundamental knowledge in finance you gained from the CFA curriculums would definitely help you along the way. However, frankly, like any other exams, what you can get out of the program are mostly concepts and theories. The program will not provide you an intense (practical) training on FX related topics, therefore, to help you do your current job, I would suggest that you go take some training courses on FX through your local Treasury association.
Long term, pursue the CFA charter would help your future career path if you want to stay in finance.
