Wall Street stocks and the dollar tumbled amid mounting uncertainty over the US economy as President Donald Trump renewed his attacks on Federal Reserve chair Jay Powell.
US equities opened lower on Monday and the sell-off intensified as Trump took aim at the central banker. The S&P 500 was down 3 per cent during lunchtime trading in New York, while the tech-heavy Nasdaq Composite dropped 3.4 per cent.
In a post on his Truth Social platform on Monday morning shortly after the market open, Trump said Powell, whom he called โMr Too Lateโ, should lower interest rates โNOWโ to stimulate the economy.
The market moves came after Kevin Hassett, director of the National Economic Council, said on Friday that Trump would โcontinue to studyโ the matter of dismissing Powell after the president claimed the previous day that he had the right to fire the Fed chair.
Trump has repeatedly criticised Powell for not lowering interest rates sufficiently swiftly, while the Fed chair has said he will never be influenced by political pressure.
โIf you think that itโs unacceptable for President Trump to be frustrated with the policy history of the Fed, then I think youโ.โ.โ.โgot some explaining to do,โ Hassett told reporters in Washington on Friday, when US markets were closed.
The dollar fell as much as 1.5 per cent to a three-year low against a basket of its key trading partners on Monday, while the euro gained 1 per cent to $1.151 and the yen strengthened 1 per cent to ยฅ140.82 versus the dollar.
US sovereign debt remained weaker on the day, but had trimmed some of its earlier losses. The yield on the 10-year US Treasury was up 0.06 percentage points at 4.39 per cent after Trumpโs latest social media post. Bond yields move inversely to prices.
Thierry Wizman, global foreign exchange and interest rate strategist at Macquarie, said the โflight from the dollarโ on Monday was being driven by growing concerns over the Fedโs independence, as well as Washingtonโs lack of progress on trade deals.
He cited the โworseningโ growth outlook in the fall in stocks, adding that the โwillingness to rein in US consumer price inflation is ebbing,ย hence the flight to gold [and] the backup in long-term [Treasury] yieldsโ.
Yujiro Goto, forex strategist at Nomura Securities, said the combination of bond sell-offs and currency depreciation at the same time was rare in a major reserve currency market such as the US.
Goto attributed the rise in the yen to concerns over US โstagflationโ and โgrowing distrust in US asset credibilityโ.
Analysts at CICC, the Chinese investment bank, said in a report on Sunday that domestic US policy uncertainty was leading the dollar and Treasuries to โbehave more like risk assetsโ.
They added that Trumpโs recent remarks about Powell โfurther heightened market concerns about the Federal Reserveโs independenceโ.
The central bank has so far kept rates on hold this year after lowering them three times in 2024. Its next meeting is in May.
The Fed sets monetary policy independently of the other branches of government. Any attempt to oust Powell, whose term is scheduled to end in May 2026, or pressure monetary policy could cause further market turmoil in the US, according to investors and analysts.
