LONDON - Investors pumped nearly $15 billion into equity funds and $13.7 billion into bond funds in the week to Wednesday, BofA's weekly fund flow data showed on Friday.

Though the overall money hosed into stocks this year is still at a record, inflows slowed down in recent weeks as major stock indexes are trading at sky-high valuations.

Under the hood, investors pulled back $1.3 billion from emerging market equities and added $1.4 billion in European stocks, according to BofA's crunching of EPFR data.

With the Bank of Canada this week signalling it will cut bond purchases, BofA said in a worst case scenario it expects central banks of the Unites States, European Union, Japan and the United Kingdom to reduce purchases to $3.4 trillion from $8.5 trillion in 2020.

It sees the big four central banks cutting bond buys to $400 billion in 2022.
