The U.K.-based Sunday Times writes, "Negative rates are here already for some investors, discussing the potential of sub-zero yields on English money markets. They say, "Investors holding a total of £9.5 billion are suffering negative returns just so they can keep their savings in cash funds. The threat of negative interest rates is growing as Bank of England economists warn that they may be necessary to help boost the economy. This has raised the prospect of banks charging savers for keeping their money safe, instead of paying a return. Yet money market funds, which are supposed to provide a low-risk investment that holds savers' nest eggs steady while earning a small rate of interest from cash and cash-equivalent investments, are already in effect charging investors to be in cash. This comes at a time when the best easy-access rates on cash accounts are about 1 per cent."
