The US Federal Reserve's internal watchdog has issued a stark warning that foreign state actors are actively seeking to compromise the integrity of the central bank's economic data, according to a report published this week. The Office of Inspector General (OIG) stated that unauthorised access to sensitive non-public information—including employment, inflation, and GDP figures—could allow adversaries to trade ahead of official releases, distorting markets and undermining confidence in the world's largest economy.
The alert has rippled through financial markets in London, where traders and fund managers are reassessing the reliability of key US indicators that drive global asset prices. The FTSE 100 closed 0.6% lower at 8,217.34 on Wednesday, with defensive stocks such as utilities and healthcare outperforming as investors sought shelter from uncertainty. The mid-cap FTSE 250 fell 0.8% to 20,445.12, while the pound weakened 0.3% against the dollar to $1.2850.
Analysts at Barclays noted that the warning, while not detailing specific incidents, highlights a growing vulnerability in the financial system's data pipeline. 'If economic releases are even suspected of being compromised, the entire architecture of market expectations breaks down,' said a senior strategist at the bank. Sectors most reliant on US data—such as mining, aerospace, and banking—saw the heaviest selling pressure in London, with Glencore and Rolls-Royce both losing more than 1.5%.
The watchdog's report comes amid heightened geopolitical tensions and follows previous alerts from US intelligence agencies about cyber-espionage targeting economic infrastructure. For UK investors, US economic data is the bedrock of portfolio decisions; the monthly non-farm payrolls and Consumer Price Index figures directly influence the Bank of England's policy path and the valuation of sterling-denominated assets.
Pension funds with exposure to US equities and bonds face particular scrutiny, as any distortion in data could lead to sudden repricing of risk. The OIG has recommended enhanced encryption, stricter access controls, and real-time monitoring of data dissemination systems. The Fed said it takes the threats 'very seriously' and is reviewing its protocols, though no specific breaches have been confirmed to date.
