LONDON, May 23 (Reuters) - Global investors admit to flying blind in markets roiled by erratic U.S. trade rhetoric and chaotic economic forecasting, stressing that placing long-term bets was harder now than at any time since the 2020 COVID-19 crisis.

Anxieties over whether a 90-day White House-China tariff truce will hold, plus U.S. budget gaps and whipsawing currencies have made investors extremely cautious about where to put their money.
