Bonds, Darling: IGSB vs. VGSH

One is occasionally asked to dabble in the rather pedestrian world of fixed income. Frankly, it’s not terribly glamorous, but one must, you know, have income. The iShares 1-5 Year Investment Grade Corporate Bond ETF (IGSB 0.21%) and the Vanguard Short-Term Treasury ETF (VGSH 0.19?) are both attempting to provide it. The distinction, as always, is in the details – and the marginally different ways one might lose a little money.

Both funds are aiming for stability in the short-term bond market, but they approach it with differing degrees of…shall we say, adventurousness. IGSB, with its corporate bond focus, offers a slightly more robust yield, though one must be prepared to accept a smidgeon more risk. VGSH, on the other hand, is the sort of fund one might recommend to a particularly timid aunt. Lower cost, perfectly safe, and rather dull, naturally.

A Snapshot, If You Must

Metric VGSH IGSB
Issuer Vanguard iShares
Expense ratio 0.03% 0.04%
1-yr return (as of Feb. 27, 2026) 4.88% 6.56%
Dividend yield 4% 4.43%
Beta 0.26 0.41
AUM $31.7 billion $22.5 billion

VGSH is, predictably, the cheaper option, but IGSB’s higher yield is a rather attractive lure for those of us who require a little extra sparkle in our portfolios. It’s a small difference, of course, but in this business, one clings to any advantage, however minor.

Performance & Risk: A Delicate Dance

Metric VGSH IGSB
Max drawdown (5 y) -5.7% -9.46%
Growth of $1,000 over 5 years $958 $970

One observes that IGSB has a slightly higher drawdown. Not alarming, mind you, but enough to warrant a raised eyebrow. The extra return doesn’t entirely compensate, but then again, life is rarely entirely fair.

Peeking Inside the Machinery

IGSB, with its 4,504 holdings, is rather like a sprawling, slightly chaotic party. No single guest dominates, which is reassuring, but one is exposed to the vagaries of corporate credit. Should a company falter, one feels the pinch. VGSH, conversely, is a very exclusive, impeccably behaved tea party with only 92 guests, all members of the U.S. Treasury. Perfectly safe, utterly predictable, and, frankly, a bit of a bore.

What This Means For Investors, Darling

Both IGSB and VGSH offer a means of investing in short-term debt. IGSB holds approximately 4,500 U.S. corporate bonds with maturities of one to five years. VGSH holds around 90 short-term U.S. Treasury bonds. Both can provide reliable income and relatively low risk. Shorter-duration bonds are typically more stable, and less susceptible to interest-rate fluctuations, making them conservative choices for investors seeking safety in a volatile market.

Naturally, corporate bonds carry a degree of risk that U.S. Treasuries do not. A company’s fortunes are, shall we say, less predictable than the U.S. government’s. However, this increased risk is reflected in IGSB’s higher dividend yield and total return. It’s a trade-off, you see. One doesn’t get something for nothing.

And a final, rather tedious detail: tax implications. Corporate bond gains are taxed as ordinary income, while U.S. Treasuries are exempt from state and local taxes. A small advantage, perhaps, but one takes what one can get.
