How large is surety insurance in proportion to the property and casualty industry?

- In the United States, surety premiums account for about 2.5% of total property and casualty premiums written.

- Global surety premiums make up under 1.5% of all general insurance premiums written.

This is because:

1) Surety bonds are required by only certain types of businesses and individuals, and

2) Surety bonds typically only cover a small portion of the total value of a project.
