Within moments of Donald Trump’s bombshell social media post backing off from his tariffs, allegations of wrongdoing were flying.
The stock market soared and the president’s opponents alleged an insider trading conspiracy as the billions of dollars in gains piled up for those who saw it coming.
Now, a former White House ethics expert has called on Trump’s inner circle to be barred from buying and selling shares while the trade war rages on.
“Until this whole tariff thing is sorted out, anyone who is an appointee of the president should not be buying and selling stocks,” says Richard Painter, formerly George W Bush’s chief ethics lawyer.
“Elon Musk, anyone who is an appointee of the president, should abstain from trading.”
In a pointed critique of Trump’s tendency to rule by social media, Painter said he would have “had a fit” if he were working for a president who talked so publicly about buying and selling stocks.
It comes after Trump wrote “THIS IS A GREAT TIME TO BUY” on his Truth Social website just hours before his tariff climbdown led to the S&P 500 posting its biggest jump since 2008.
“I made it clear in the Bush White House that this kind of thing couldn’t happen,” says Painter. “We’re not investment advisers.”
He has called on Trump to issue an executive order to block any of his aides from trading, while also stressing that there should be “no more talking about the market”.
Although there is no evidence that anyone close to Trump has acted on inside information, anger is building.
Nasdaq call volumes spiked in the hour before Trump unveiled his turnaround, as traders bought the right to purchase shares at a certain price.
Unusual Whales, a research firm that tracks market data, said that some of the trades were what is known as “zero DTEs”, meaning zero days to expiration.
An analyst at the firm said: “These options, as the name implies, expire the same day as purchase, making them much riskier than farther-dated options. The sharp increase in equities [last night] created exponential gains for those correctly positioned.”
And for every dollar gained, someone else lost out.
“Did anyone buy or sell stocks, and profit at the public’s expense?” said Adam Schiff, a Democrat senator in California, on social media, as he called for an urgent investigation into potential insider trading.
Following Wednesday’s swing in the markets, traders around the world said they had never seen anything like it.
Peter Hargreaves, the billionaire co-founder of Hargreaves Lansdown, said the recent turmoil caused by Trump’s tariffs was “in a different league” to what he had experienced before.
