As major economies across the globe—including the U.S.—followed QE measures in the aftermaths of the 2008 financial crisis, a good portion of the QE money made its way into money market mutual funds as a haven. This migration of funds has led to interest rates remaining low for a long duration, and the diminishing of returns from money market funds.
Ultrashort bond funds are mutual funds, similar to money market funds, that, as the name implies, invest in bonds with extremely short maturities. Unlike money market funds, however, there are no restrictions on the quality of the investments they hold. Instead, ultrashort bond funds typically invest in riskier securities in order to increase their return. Since these high-risk securities can experience large swings in price or even default, ultrashort bond funds, unlike money market funds, do not seek to maintain a stable $1.00 NAV and may lose money or dip below the $1.00 mark in the short term. Finally, because they invest in lower quality securities, ultrashort bond funds are more susceptible to adverse market conditions such as those brought on by the financial crisis of 2007–2010.
When comparing money market mutual funds a few patterns arose. First, when it comes to expense ratios, or the annual fees you’ll pay to own the funds, 0.25% is a threshold that separates the top and bottom half of the money market mutual funds in my short list. When it comes to yields, 2.1% is a defining 7-Day Yield threshold. For YTD yields, 1.4% is a benchmark that separates the pack.
Over time, money market fund "depositors" felt more and more secure, and not really at risk. Likewise, on the other end, corporations saw the attractive interest rates and incredibly easy ability to constantly roll over short term commercial paper. Using rollovers they then funded longer and longer term obligations via the money markets. This expands credit. It’s also over time clearly long-term borrowing on one end, funded by an on-demand depositor on the other, with some substantial obfuscation as to what is ultimately going on in between.
The best money market accounts have low or no minimum balance requirements. And if they do have higher balance requirements, the best money market accounts reward you for keeping this balance. The balance requirement doesn’t really matter, as long as it’s within what you plan on keeping in the account so that you earn a maximum APY and don’t incur fees.
This flexibility makes Ethereum the perfect instrument for blockchain -application. But it comes at a cost. After the Hack of the DAO – an Ethereum based smart contract – the developers decided to do a hard fork without consensus, which resulted in the emerge of Ethereum Classic. Besides this, there are several clones of Ethereum, and Ethereum itself is a host of several Tokens like DigixDAO and Augur. This makes Ethereum more a family of cryptocurrencies than a single currency.
If this sounds similar to banks’ high-yield savings accounts or money market accounts, it is. The largest difference lies in the ability for yields on money market mutual funds to rise proportionately with interest rates. For example, as interest rates have risen, the yields on most bank money market accounts (which are set by the banks themselves) have stayed relatively flat, while money market mutual fund yields have increased.
