Reza Zarrab had been due to go on trial on Tuesday in Manhattan federal court, but the prosecution made clear that Zarrab was, instead, their star witness.
The lone man in the dock is now Turkish banker Mehmet Hakan Atilla, accused of violating sanctions against Iran, bribery and money laundering.
The case has provoked the ire of Turkish President Recep Tayyip Erdogan, further straining ties between NATO allies Washington and Ankara.
Analysts believe revelations in the trial could implicate Turks close to Erdogan. Ankara had demanded for months that Zarrab be freed to avoid the trial.
Zarrab, 34, testified that he met Turkey's former economy minister, Zafer Caglayan, in 2012 as Zarrab sought to establish himself as the prime intermediary in lucrative gold traffic involving Turkish and Iranian banks.
The gold-for-oil operation enabled Iran to use revenue from its oil sales for payments on global markets despite the prohibition against US banks doing business with Tehran.
Caglayan offered to help Zarrab become the principal go- between for the Turkish public bank Halkbank, Zarrab testified, wearing beige prison garb.
At the time Zarrab was best known in Turkey for his lavish lifestyle as well as his wife, the famous Turkish singer Ebru Gundes.
Zarrab told the court he paid 45 to 50 million euros (USD 53.5 to USD 59.4 million) plus approximately USD 7 million in bribes to the minister between March 2012 and March the following year.
The defendant, Attila, is deputy chief executive of Halkbank.
Caglayan resigned from the Turkish government at the end of 2013 during a wide-ranging Turkish corruption scandal that saw Erdogan, then prime minister, replace nearly half his cabinet as his own hold on power was threatened.
They were accused of receiving bribes from Zarrab to facilitate UN sanctions-busting trade with Iran and other deals.
US authorities, however, in September this year charged Caglayan and eight other people with carrying out hundreds of millions of dollars in transactions benefitting Iran and Iranian entities in violation of US sanctions.
Caglayan remains on the run, and Attila is the only one of the nine currently on trial.
Zarrab testified yesterday that Attila helped to doctor the trade so that the Iranian origin of the funds would be undetectable by US banks.
Defence lawyer Victor Rocco warned on Tuesday that he intends to discredit Zarrab, dubbing him a "liar" and corruption expert who was looking to bribe his US guards.
Zarrab confirmed yesterday that he tried to bribe his guards in exchange for alcohol and a cell phone.
