There has been no obvious catalyst for the fall in yields. However, it is notable that the decline has been global. For example, overnight long end yields in Germany and the U.K. declined by 8-11bp while U.S. treasury yields declined by 4-7bp as U.S. 30 year yields reached their lowest level since July.
The fall has been more pronounced in the real yield space (the interest rate adjusted for inflation). This week, U.S. 30 year real yields traded to a record low, and U.S. 10 year real yields broke below the bottom of a well-established range at -100bp, to close overnight at -117 bp, within touching distance of their -119bp low from August of this year.
The decline in yields is more surprising because economic data has been encouraging of late and inflation concerns remain. Most likely, the move is in response to traders unwinding positions after key central banks’ meetings last week were dovish compared to market expectations.
Aside from gold, the decline in yields has the potential to impact the FX space. As can be viewed on the chart below the U.S. dollar index, the DXY has closely tracked the move in real yields. It currently appears almost 2% overvalued at its current price of 94.00.
If the DXY index breaks uptrend support at 93.50 coming from the May 89.53 low, it increases the risk of a deeper pullback in the DXY index towards the support provided by the 200 day moving average of 92.00.
