Oil prices and bond yields are spiking a bit after Trump comments that suggested an uncertain timeframe for the Iran war.

MBS are now unchanged on the day, down 6 ticks (.19) from some lenders' rate sheet print times. Most lenders are in a position to consider a negative reprice, but only the jumpier lenders tend to pull the trigger at this level of weakness. 

10yr yields are unchanged at 4.266.
