They tell us nothing about the markets.
They tell us the Fed has decreed that interest rates be essentially zero, so the Federal Government interest expenditure doesn't blow up in its face.
At least not right away.
All the fed has to do is sell those treasuries and the rates go up. They don’t have to raise interest rates they charge. Just sell all their 10s and 30s.
Problem is the bond market and the housing markets crash when the rates go up.
