Reuters reports that BofA’s March fund manager survey showed that investors have slightly increased their cash allocation, deeming that inflation and ‘taper tantrums’ could topple the record rally in financial markets.

Fund managers asked by BofA increased their cash allocation to 4% from 3.8% in February.

A rise above 2% in U.S. 10-year Treasury yield could cause more than a 10% correction in stocks, 43% of investors surveyed by BofA with $630 billion in assets under management said. And a rise to 2.5% could make bonds attractive relative to stocks.

Though the quickfire bond selloff in the last few weeks dented tech stocks wiping hundreds of billions from the sector’s market capitalization, ‘long tech’ remained the most crowded trade in the survey.

Rising rates have also prompted a rush to commodities. Investors are currently their most optimistic on commodities in the survey’s near two-decade history.
