JAKARTA, Jan 19 (Reuters) - Indonesia's central bank raised its key policy rate by 25 basis points on Thursday, its sixth hike since August as it battles to get inflation back within its target this year.

Bank Indonesia (BI) raised the 7-day reverse repurchase rate to 5.75%, as expected by the majority of economists in a Reuters poll.

It also lifted its deposit facility and lending facility by the same amount to 5.00% and 6.50%, respectively. (Reporting by Gayatri Suroyo, Fransiska Nangoy and Stefanno Sulaiman Editing by Ed Davies)
