World stocks and gold paused their latest steep rally on Thursday as a series of warnings about excessive stock valuations and overly loose policy settings reverberated through global markets.
International Monetary Fund boss warned about risk to the world economy from potentially large corrections in lofty stock markets, while she also noted that fiscal policies were too lax worldwide, adding "don't get too comfortable." The caution followed the earlier on Wednesday about the risk of a sharp reversal if investor moods soured on doubts about AI or Fed independence.
And JPMorgan chief Jamie Dimon on Thursday added his voice to warnings of a risk of significant pullback in the U.S. stock market over the next year or two. "I am far more worried about that than others," he told the BBC.
Despite the trepidation, soundings on the AI frenzy ahead of this month's corporate earnings season remained upbeat and the world's largest contract chipmaker TSMC reported another forecast-beating, AI-driven jump in annual revenue of 30%.
China's markets also returned in buoyant form from the Golden Week break and played catch-up to the global stock gains in their absence. Chinese chipmakers surged on more pressure in Washington for broader bans on exports of chip equipment to China and rare earth indexes jumped as Beijing tightened export controls of the strategic minerals.
Europe held on to Wednesday's recovery in French markets as President Emmanuel Macron batted away speculation of another snap election and said he would appoint a new prime minister within 48 hours to end the latest political hiatus.
Back on Wall Street, there was some cooling of the week's main moves today after fresh closing highs for the main stock indexes on Wednesday. Gold stalled at new records after surging past $4,000 earlier in the week. With official data still thin on the ground amid the U.S. government shutdown, investors took their cue from Fed minutes that nodded to further easing even as inflation worries linger. Stock futures were flat and U.S. Treasury yields nudged up a bit, however, after a mixed 10-year note auction late Wednesday and ahead of the long-bond sale later today. The dollar held much of the week's gains, with the yen sliding through 153 for the first time since February as Japan's next likely new prime minister Sanae Takaichi pledged to reassert government sway over the Bank of Japan.
