Serb, Bosniak and Croat nationalists look to have held on to Bosnia's three-person presidency, according to partial results released on Monday.
Under Bosnia's complex electoral system, the country as a whole has three presidents – one from each of the country's major ethnic groups.
Over 90 percent of votes from Sunday's elections are now counted. The country is also divided between two semi-autonomous entities, Republika Srpska and the Muslim-Croat Federation.
While the Serbian seat remains contested by two nationalist parties, Dragan Covic of the Croat HDZ BIH party and Bakir Izetbegovic from the Muslim SDA have claimed to have locked in their victories, according to Al Jazeera.
The SDA and Serbian SNSD also appear to have won big in the national assembly, though final results are yet to be released.
In the semi-autonomous Serbian region, the Republika Srpska, incumbent president Milorad Dodik is leading in the count.
Dodik says he wants to move Republika Srpska closer to full statehood. Around 3.3 million Bosnians were eligible to vote, though only 54 percent turned out on Sunday, after months of tension over economic concerns.
In February, the country's stuttering economy sparked some of the worst unrest in Bosnia for over a decade, with thousands taking to the streets to protest.
In the lead up to elections, campaigns in both regions of the country focused on the economy and unemployment, as many voters remain concerned about Bosnia's future.
“Nothing functions in this country,” one Bosnian in Sarajevo, Mirsada Grgo told AFP.
“The time has really come for a change. People have been sleeping for too long, and this is their last chance to wake up,” Grgo said.
