Global equity markets made solid gains this morning, setting up U.S. markets for another potentially positive day — futures contracts on the SP 500 index were up 0.3% this morning, pre-opening bell. But lurking behind the good news were worries about the increasing weakness of the U.S. dollar vs foreign currencies. India’s Nifty 50 was up more than 2% today on hopes that it is well-positioned to benefit from U.S. supply chain operations moving out of China. The Indian market is the first major index to completely erase the losses caused by President Trump’s trade war. The gains came after a good day in the U.S. on Monday. The Dow climbed more than 300 points on Monday as markets continue to rally on the prospect of tariff exemptions. That translates to a 0.78% increase, while the SP 500 rose 0.79% and the tech-heavy Nasdaq jumped 0.64%. One highlight was Palantir, which was up nearly 5%. The SP is still down 8% year-to-date, however. Here’s a snapshot of today's action from Fortune's CEO Daily: Futures on the SP 500 were up 0.3% this morning. Japan’s Topix was up 1%. The Stoxx Europe 600 was up 1% in early trading. The U.K.'s FTSE 100 was up nearly 1%. China’s two main indexes were flat. Hong Kong’s Hang Seng was up 0.2%. India’s Nifty 50 was up 2%-plus. It’s not all blue skies and plain sailing, however The U.S. dollar fell for the fifth straight day, as tracked by the DXY, an index that represents a basket of major trading currencies. The dollar is down nearly 8% this year. To put that in perspective: In late 2022 the dollar reached near-parity with the British pound, but today sterling buys $1.32. The dollar’s weakness is a sign that, in one way or another, investors are moving money out of the U.S. The exits have been so severe that some analysts are starting to question the role of the dollar as the world’s “reserve currency.” “At its heart, the USD's weakness reflects the USD's changing 'structural' relationship to 'risk' when it is the US that is now being seen to be dismantling the international trade system and capital-flows system that it itself created. If the U.S. itself cannot be counted upon as a reliable harbor in a turbulent world, how can the USD be favored?” wrote Macquarie analysts Thierry Wizman and Gareth Berry in a recent note to clients. “The USD's status as a reserve currency was always part 'convention' and part 'practicality' in view of the stability of US institutions."  The chatter about the U.S. behaving like an “emerging market” isn’t going away either. “Experienced investors will recognize this pattern. It’s one we typically see in an emerging market crisis when investors lose confidence in a country’s government and its ability to service its debt. The result is capital flight and a rapid sell-off of government bonds as the risk premium increases,” Panmure Liberum’s Joachim Klement wrote yesterday. The U.S. bond market is indeed struggling with a departure from the dollar The market for high-yield corporate bonds has ground to a halt, with zero issuance since Trump’s “Liberation Day.” The private equity sector is highly dependent on junk debt to fund takeovers and the freeze threatens the cash lifelines of riskier companies that cannot survive without debt funding. And China may be selling U.S. bonds. It’s not clear what is going on, exactly. China holds a lot of U.S. Treasuries — so selling them would hurt Beijing as much as Washington. Having said that, damaging the U.S. bond market is a pretty good way to fight a trade war. This combination of events—investors exiting U.S. equities, bonds and the dollar all at once—is rare, according to Goldman Sachs. “During the large 'risk off' shift across assets before the rebound on Wednesday last week the SP 500, U.S. 10-year bonds and the Dollar sold off together. Such episodes have been rare since the Great Moderation with only 2 short episodes since 2000 – being more common in the 1970s stagflation period and the 1980s,” Christian Mueller-Glissmann and his team wrote in a note to clients seen by Fortune.
