English to Portuguese Art/Literary Journalism economia

Oi, pessoal.

Eu preciso de ajuda com o termo acima. Contexto:

"To place this inversion in focus, it helps to be in Brazil, where winter (so to speak) arrives with the Northern Hemisphere summer, and economic optimism, as exuberant as the vegetation, increases at the same **brisk clip** as U.S. foreclosures."

Obrigada,

Christina.
