A high-profile incident occurred on Thursday evening. U.S. President Trump posted on his social media platform the key U.S. non-farm employment data that had not yet been officially released, nearly a day ahead of the official release time. The chart shows that since January this year, the U.S. private sector has added 654,000 jobs, while government employment has decreased by 181,000 jobs. These data were originally scheduled to be released by the U.S. Department of Labor along with the December non-farm employment report on Friday.

The White House later responded that this was an "unintentional act" and stated that they would review the procedures for releasing economic data and embargo agreements. Officials explained that the President is legally entitled to receive some economic data in advance, some of which come from legitimate early briefings, but should not be made public during the embargo period. Trump himself said it was not his responsibility, jokingly stating, "Let them publish it if they want."

Interestingly, this is not the first time that an incident has been triggered by early hints or disclosures of non-farm data. Market performance shows that after the event, U.S. stock index futures only fluctuated slightly during light trading hours, with no obvious anomalies so far.

However, analysts have issued warnings. KPMG Chief Economist Diane Swonk pointed out that leaking such sensitive data early could undermine market fairness and prompt investors to make hasty decisions before the official announcement. For the market, such incidents could weaken investors' trust in the neutrality and credibility of U.S. official economic data — which could be a big problem for any data-driven trading strategies.
