- iShares Premium Money Market ETF (CMR)
- Purpose Cash Management Fund (MNY)
- Global X 0-3 Month T-Bill ETF (CBIL)
MNY invests 100% in money market securities. Indicated yield 4.69%. Effective duration is 0.22 years so this is very short term paper. Money market securities are not guaranteed but are considered cash equivalent due to their short term. We would note asset-backed paper did see some problems in 2008. CBIL indicated yield is 3.60%. Duration is 0.11 years. The fund itself is not guaranteed, but with 99% invested in government securities it effectively is. CMR is essentially equivalent to MNY, indicated yield 4.36% but with only 4% corporate exposure. Duration 0.17.
We would rank in terms of low risk first: CBIL, CMR, MNY
