Last week’s decline in 10-Year rates was the biggest since September, catalyzed by Fed easing of 25 basis points.  The chart implies there could be a further fall to as low as 3.706%, but I have my doubts. In fact, the steep slide triggered a ‘mechanical ‘buy’ at 4.073% that suggests rates are more likely to rise from here or perhaps a little lower, to at least 4.452%, than they are to fall below 3.937%.  If they crack that last number hard, however, odds of more slippage to 3.706% would be no worse than 50-50.  FYI, I’ve substituted the 10-Year for the 30 because the shorter duration is a more sensitive indicator of interest rate risk. ______ UPDATE (Feb 20): As anticipated, rates have taken a so-far modest bounce from just beneath last week’s settlement level. If the upward trend is going to get legs, a push above the 4.206% peak recorded on Feb 11 would announce it.
