Re.: Relevant event

Please be advised that Fitch Ratings has informed us, that in line with Fitch’s recent lowering of the Argentine government's bond ratings they have assessed the ratings of Argentine Financial Institutions and consequentially downgraded the global ratings of Banco Macro S.A., particularly Banco Macro’s senior unsecured debt rating to CC/RR4 from CCC/RR4, and the foreign currency subordinated debt rating to C/RR6 from CCC-/RR6.

Sincerely,

SIGNATURE

Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned, thereto duly authorized.
