How Rho quotes yields
Every yield figure on Rho’s site follows the disclosure standard for its instrument type, carries the date it was measured, and reflects fees where stated. Here is exactly how each number is calculated.
U.S. Treasury Bills
T-Bills are individual securities, not funds, so SEC yield standards for funds do not apply. Where a T-Bill yield appears on Rho’s site, it is the trailing 7-day average U.S. T-Bill yield (13-week), source: U.S. Department of the Treasury. [Pending: Rho plans to quote the yield of its own most recent T-Bill purchases once a product-sourced feed is available; this section will be updated when that ships.]
Money market funds (Morgan Stanley MULSX)
Money market funds are quoted using the 7-day SEC yield — the industry standard for short-term cash instruments. It annualizes the fund’s income over the trailing seven days, net of fund expenses.
Bond funds (Vanguard VFSTX)
Bond funds and fixed-income ETFs are quoted using the 30-day SEC yield, the standardized measure regulators require for these funds. It reflects the fund’s earnings over the trailing 30 days, net of fund expenses.
Fees, and what “net” means
Rho Treasury charges a tiered annual management fee based on total Rho deposits: 0.15% at $20M or more, 0.25% for $10–20M, 0.35% for $5–10M, 0.45% for $2–5M, and 0.60% (the maximum) for balances under $2M. Rho Treasury requires a $100,000 minimum investment. A figure labeled “net” is the instrument’s published yield minus the fee at the stated tier. Where Rho quotes a single “up to” figure, it is net of the lowest fee (0.15%, the $20M+ tier).
Blended portfolio yields
When we show one number for a mixed allocation, it is the weighted blend of the figures above, net of Rho’s management fee — the same calculation your dashboard shows in real time.
Dating and update cadence
Yields change daily, so every figure we publish carries its as-of date. Fund yields refresh from the funds’ published SEC yields; the T-Bill figure is a trailing 7-day average and updates on the U.S. Department of the Treasury’s publication schedule. If you see an undated yield anywhere on our site, tell us — that’s a bug, not a policy.
What yields are not
Rho Treasury holds securities. They are SIPC-protected, not FDIC-insured, and values can fluctuate, including possible loss of principal. For FDIC-insured cash, Rho business savings carries coverage of up to $75 million through a sweep network of 400+ FDIC-insured banks; checking deposits are insured up to $250,000 at Webster Bank, N.A., Member FDIC.
Why we publish this
Yield marketing in business banking is full of undated numbers and mismatched measures. Quoting a money market fund and a bond fund on the same basis — or leaving off the date — makes comparisons meaningless. We’d rather show the math.
