Sure, let’s say the yield curve currently looks like this:

1 year: 1.5%

2 year: 1.75%

5 year: 2%

10 year: 2.5%

20 year: 3.15%

we can see the slope of the yield curve is currently positive (as it starts low, and the yields increase with time).

If we apply the following factor values:

1 year: 0.52%

2 year: 0.34%

5 year: 0.13%

10 year: -0.13%

20 year: -0.41%

We get the resulting interest rate curve:

1 year: 1.5%+0.52%=2.02%

2 year: 1.75%+0.34%=2.09%

5 year: 2%+0.13%=2.13%

10 year: 2.5%-0.13%=2.37%

20 year: 3.15%-0.41%=2.74%

The slope is still positive, but it is much more flat now as the rates only slightly increase with time. So the slope has changed due to this factor
