Today, mortgage-backed securities (MBS) were up +6/32. Some favorable repricing was seen.
Though no economic data was released today, the National Association of Realtors Monthly is releasing the Existing Home Sales Index report tomorrow (6/21/2017) at around 7:00 PDT, which indicates the number of existing homes sold. The report can predict the future national mortgage origination volume.
The day after (6/22/2017), the Employment and Training Administration of the Department of Labor is releasing Jobless Claims. When unemployment goes low enough, there is a possibility that it can put wage pressure on the economy, increasing in interest rates.
