In the past week, the bond market has experienced a historic selloff. Yields on benchmark 10-year US Treasuries soared towards 4.9% while those on 30-year debt reached the highest since 2007. But the exact cause of these dramatic moves in the most important market in the world aren't entirely clear, with people looking at everything from the Federal Reserve's outlook for interest rates, to the the jump in the price of oil, or booming supply as the deficit expands, as well as more technical things like the term premium. So what's driving the selloff and how do we disaggregate interrelated things like supply and demand? How do you decompose longer-term and short-term factors feeding into the price of US Treasuries? What can stem the big moves? And what are investors saying about their appetite for US debt? We speak with Jay Barry, co-head of US interest rate strategy at JPMorgan Chase, about the big bond market selloff.
