Majority of US Goverment Debt Comes With a Very Short Maturity

Is it normal that a majority of US debt comes with a very short maturity (under 3 years), look at the official current chart here: https://www.treasurydirect.gov/govt/reports/pd/feddebt/feddebt_ann2021.pdf (page 23, Maturity chart)?

I'd expect much more debt maturing farther in the future.

This looks like a disaster brew for bonds interest hike, as the tapering progress: https://www.newyorkfed.org/markets/...ities/treasury-securities-operational-details

Any expert on bonds here?

 

It sounds like more QE on the horizon. They just needed a reason to make it legit.

 

all along, short maturity date debt has higher volume,
and long-maturity debt lower volume.

also note that
in terms of volatility, long-term debt has higher volatility than short-term debt.

 

It would behoove them to lock in low rates long term if they can find buyers.

 

Much easier to roll coupons.

There hasn't been much commercial demand for longer term paper, either.
