The disputed material includes tax filings, financial records, and entity-ownership papers tied to about 400 corporate entities.
The stay doesn't mean the fight is over. Trump's lawyers asked for the emergency ruling a day earlier, arguing that the BBC's demand was too broad.
They also said that once the network saw the records, the damage couldn't be undone. If a later court decided the order was wrong, the information would already be out there.
The records battle is part of a much bigger lawsuit.
The problem was the editing. The documentary cut together Trump's speech that day so it looked like he was telling his followers to storm the Capitol.
The BBC has apologized, but it insists the mistake was an accident and not defamation, the legal term for damage to a person's reputation.
Trump tells a different story. He says the documentary hurt his personal brand, his properties, and his businesses, so his finances belong in the case.
The BBC counters that it needs the financial material for a practical reason.

It wants to check whether Trump's businesses actually suffered the losses he is claiming, and whether any of that harm could plausibly be linked to a show that was broadcast mainly in Britain.
In July, U.S. Magistrate Judge Enjoliqué Lett sided with the BBC. The judge decided that Trump's lawsuit made both his reputation and his company finances fair game.
"All of President Trump's brand, properties and businesses are impugned or said to have been impugned," Lett wrote. "Reputational, economic damages, all of that is now at issue in this case."
That ruling is what set up this week's emergency request.
The BBC case is not the only legal fight Trump has with a news outlet.
He has also filed claims against The New York Times, The Wall Street Journal, and ABC News, and CBS parent Paramount has previously settled lawsuits he brought.
There's also a strategy question embedded in the records fight. Trump's attorneys want to revise the lawsuit so it centers on damage to him personally rather than on corporate losses.
That move would change the shape of the case even if the dollar amount stays the same. It could limit what the BBC can demand while preserving the $10 billion claim.
The BBC had not commented when contacted.
For investors, the headline number in any lawsuit is only half the story. The part that matters more is what the legal fight forces into the open.
Anyone can claim a huge number. The real fight is over the evidence.
Trump is claiming $10 billion in damage to his brand and businesses. To defend itself, the BBC wants to test that claim against real financial documents.
The bottom line: when you ask for a fortune in damages, your own books can become evidence. That's how the system is supposed to work, and it's true whether the name on the courthouse door is a famous one or just a brand you follow in the news.
The number at the top of a lawsuit gets the attention. The paperwork is what does the work.
