Indonesian president-elect Joko Widodo (L) and vice president-elect Jusuf Kalla gesture after a press conference in Jakarta on August 20, 2014.

The Jakarta Composite surged to a fresh 15-month high Friday morning after Joko Widodo was confirmed as president of the world's third-largest democracy.

Stocks powered to a high of 5223.975 in early trade before falling slightly, while the rupiah strengthened 0.3 percent to 11,662 rupiahs per U.S. dollar after Indonesia's highest court upheld the July election result on Thursday. The result was in question after losing candidate Prabowo Subianto claimed that Joko Widodo – commonly known as Jokowi– cheated.
