USE Cases


Pursue yields competitive to money markets, with low volatility

Ultrashort ETFs can give your clients' portfolios returns that are competitive with money markets but with liquidity benefits, too. They offer strong yields because they are often comprised of 0-to-3 month or 1-year Treasury bills, whose yields historically have been competitive with money markets and higher than short-term CD and savings rates, as this next chart shows. Short-term Treasury indexes also have historically stable price records, which can help deliver stable NAV in indexed Ultrashort funds (see VBIL chart further down this page.) And because they are ETFs, they can also offer greater day-to-day liquidity.

Notes: The Fund is not a money market fund and is not subject to the strict rules that govern the quality, maturity, liquidity, and other features of securities that money market funds may purchase. The Fund’s investments may be more susceptible than a money market fund is to interest rate risk, which is the chance bond prices overall will decline because of rising interest rates, and credit risk, which is the chance a bond issuer will fail to pay interest and principal in a timely manner or that negative perceptions of the issuer's ability to make such payments will cause the price of that bond to decline. The Fund does not seek to maintain a stable net asset value of $1.00 per share.

Sources: Savings and CD rates are from the Federal Deposit Insurance Corp. (FDIC) as of December 15, 2025; money market rates from the Securities and Exchange Commission as of December 31, 2025; T-bill rates from Bloomberg, as of December 31, 2025.


Boost practice management with this alternative to rolling Treasuries

Many clients want their advisor to shield their short-term cash investments from potential losses. Advisors often accomplish this by rolling Treasuries. However, ultrashort bond funds can deliver similar benefits with lower volatility without the need to constantly manage a rolling Treasury sleeve. Rolling your clients’ short-term cash needs in and out of one fund that essentially resembles a rolling Treasury strategy requires much less effort. This strategy frees you up to perform higher-value work for your clients, like financial planning, wealth management, and active management of asset class exposures that are more complex. In short, ultrashort bond funds can help add value to your practice and your clients’ portfolios.

 

An ultrashort bond ETF is an efficient tool

Enhance or replace bond ladders for precision and flexibility

Integrate ultrashort bond ETFs to inject liquidity into bond ladders. Such a fund can serve as a sweep account feeding various client investing needs and strategies.

Sweep income generated by coupons and bond maturities into an ultrashort ETF. Portfolios may benefit from potentially higher yields than a money market. Plus, they can provide continued market exposure without sacrificing liquidity as you assess your next move. You may siphon some of that into the purchase of new ladder positions, or into a core bond ETF to enhance diversification of the ladder, or as cash payments to meet client obligations. You’ll enhance portfolio efficiency and demonstrate proactive value to your clients.

Ultrashort funds can also serve to replace bond ladders entirely when paired with short-term bond ETFs. Using this strategy, advisors can invest in a more diversified portfolio of bonds, at a much lower cost. Plus, this strategy is more liquid—making it easier to adjust to unexpected needs—than bonds.

FAQ

Ultrashort bond Bond funds — Advisor FAQs

Ultrashort bond funds invest in short-maturity bonds and securitized assets, so their net asset value (NAV) can fluctuate. They are not FDIC-insured and should not be considered a cash substitute. Money market funds aim for a stable $1 NAV under strict quality/maturity rules, while CDs are bank deposits insured up to $250,000.

The key risks are interest rate sensitivity (duration) and credit spread sensitivity (spread duration). Funds with more credit exposure or longer effective maturity will show greater price movement when spreads widen. Vanguard’s VUSB, for example, maintains an average duration of about 0.9–1.0 years to limit volatility.

Ultrashort sits one step out from cash—offering higher income potential with limited (but nonzero) volatility. Advisors often use ultrashort ETFs as part of a tiered liquidity approach, complementing bond ladders or serving as a sweep account for maturing securities and coupon payments.

Historically, high-quality Ultrashort bond strategies have held up better than equities during severe drawdowns, though they are not risk-free. On top of their albeit limited interest rate risk exposure, advisors should monitor credit quality and spread exposure, as widening spreads can cause temporary price declines.
