NEW YORK, Aug 24 (Reuters) - A gauge of global equity markets neared a record high on Monday, as coronavirus treatment hopes bolstered risk appetite and lifted the S&P 500 and Nasdaq to all-time peaks, which buoyed the dollar.
U.S. regulators on Sunday authorized the use of blood plasma from recovered COVID-19 patients as a treatment option. Shares of AstraZeneca rose on a Financial Times report that the U.S. government was considering fast-tracking its experimental vaccine. U.S. Food and Drug Administration's move to give emergency authorization for the use of anti-body rich plasma was hailed by President Donald Trump. It came a day after he accused the FDA of impeding the roll-out of treatments until after the Nov. 3 presidential election. World Health Organization was cautious about endorsing the use of the plasma to treat those who are ill, saying evidence that it works remains "low quality." announcement came on the eve of the Republican National Convention. Trump on Monday was formally nominated as the party's candidate for the presidency for another four years. Erlam, senior market analyst at OANDA in London, said that while it was a highly political move on Trump's part, "everyone wants to be the first to market, everyone wants to get the economy back on track and slow down the death rate."
"When you add it all up, it's positive COVID news for the market," he said.
