If you want exposure to interest rate risk, you're generally better off getting it in the futures market than the physical one. Roughly speaking, instead of buying $200k of 2-year treasuries, you can open a single 2-year treasury futures contract, fully fund it with a 3-month treasury bill purchase, and get the same return.

Why do this? Treasury bond income gets taxed as ordinary income, while treasury futures get treated as 60% long-term and 40% short-term capital gains. The extra compensation you receive for taking on this risk is more favorably taxed if you do so through futures.

(You also don't have to fully fund the futures position, but that's a longer and separate discussion. From a theoretical perspective, a stock/bond portfolio should take the best risk-adjusted return mix and then lever it up or down somewhere short of the Kelley Criterion maximum, depending on personal timeline. The best place to take on leverage is where you have the most information about what you're levering, so this means treasuries in general and short-term treasuries in particular. There's also bet-against-beta as an investing factor - rational market participants can have leverage restrictions, so they rationally overbid on investments that need less leverage to get the desired return. This holds generally across markets, and in treasuries it means that getting duration through 2-year treasury futures is cheaper than through 30-year treasuries).

Hello from the Bogleheads 90/60 thread ;-)

For others, you can extend this to building a 60/40 balanced equity portfolio. See: https://www.bogleheads.org/forum/viewtopic.php?f=10&t=256020
