CFA level 3 - Fixed Income - Example 4 - Tightening of Spread concept for Inter Market trade

CFA Level III Fixed Income
#1

When spreads tighten between two countries shouldn’t the yield decrease for Greek, why is it increasing in the Exhibit?

Can someone explain this concept of spread widening/tightening between two countries for Inter Market trade - what happens to the yield of the 2 countries? How do we know which yield is increasing and which is decreasing when they say tighten?

#2

Spread widening- difference becoming larger. Spread tightening - difference becoming smaller. I assume you are referring to Exhibit 45. The Greek Government curve is as of TODAY. The tightening expected is for the NEXT FEW YEARS.
When they say tighten or widen, it is relative to one-another.
