1. Why are some investors of the view that yields on 10-yr Treasuries might be at 2% by year-end?

this was my answer

Because the $22 trillion Treasury market is a key indicator of the economic landscape in the United States and beyond, recent dramatic falls in 10-year yields, the main reference rate for the global cost of capital, sparked consternation.

Driven by fears the economic recovery was peaking and that central banks might exit pandemic-era stimulus prematurely, the rally fed on itself as bond bears caught on the wrong side of the trade scrabbled to get back in.

and this was the reply

Regarding question 4, there are many different views on the direction treasury bond yields will take by the end of the year. Personally, I believe because we did not meet the threshold of hiring 200,000 employees, the Feds will wait off to implement their new tapering policies, making it more likely that these yields will grow to 2%.
