By letter dated September 13, 2010, the staff of the Securities and Exchange Commission (the “Staff”) provided certain comments on Banco Macro S.A. (Macro Bank, Inc.) (the “Company”)’s annual report on Form 20-F for the fiscal year ended December 31, 2009 (the “2009 Form 20-F”), which was filed with the Securities and Exchange Commission (the “Commission”) on June 1, 2010. In response to the Staff’s comments, the Company submits the responses below.

2. Please provide to the staff the information required by Item 7.B.2 of Form 20-F and revise future filings accordingly. Alternatively, confirm, if accurate, that Instruction 2 to Item 7.B is applicable and revise future filings accordingly.

In connection with the preparation of the 2009 Form 20-F, the Company conducted internal inquiries to obtain the information necessary to update its disclosure in accordance with the instructions to Form 20-F. These inquiries included, the identification of contracts to which the Company or any subsidiary is a party that (i) are not contracts that ordinarily accompany the kind of business that the Company and its subsidiaries conduct, (ii) fall under any of the categories set forth in paragraph 4(b) of the “Instructions as to Exhibits” of Form 20-F, or (iii) are otherwise considered material under paragraph 4(c) of the “Instructions as to Exhibits” of Form 20-F.

Based on such inquiries, the Company concluded that, during the two years immediately preceding publication of the 2009 Form 20-F, the Company and its subsidiaries did not enter into or become a party to any contract that is required to be disclosed under Item 10.C of Form 20-F.

4. The Consolidated Income Statement on page 53 indicates it is presented under the measurement methods provided by the Central Bank but under the US SEC disclosure requirements. Please tell us and revise future filings to clarify the specific nature of the organization and development expenses you are amortizing and the provision for losses other receivables and other allowance that you present in the Consolidated Income Statement. Clarify the US GAAP guidance that you relied on for your reconciliation to US GAAP and the associated US GAAP accounting policies.

As indicated in the Company’s audited consolidated financial statements as of and for the years ended December 31, 2009 and 2008 (see notes 4.4.l), 26 and 35.5.), “Amortization of organization and development expenses” includes primarily:

Costs related to information technology projects (purchased software): under Central Bank Rules, the Company records as expenses software costs relating to preliminary application development and post–implementation stages of software development. Central Bank Rules allow capitalization of certain costs that are not eligible for capitalization under ASC 350- 40. The Company follows the requirements of ASC 350- 40 for its US GAAP policy with respect to such costs. Please see also note 35.5.b) of the Company’s audited consolidated financial statements as of and for the years ended December 31, 2009 and 2008.

Differences due to court orders: under Central Bank Rules, the Company records under this item exchange differences related to payments and provisions made by the Company in relation to the constitutional protection and court judgments resulting from court decisions mentioned in note 2 to the Company’s audited consolidated financial statements as of and for the years ended December 31, 2009 and 2008. Under ASC 450, the right to obtain compensations for this asset is deemed a contingent gain that cannot be recognized until realized and, therefore, the Company includes this in the US GAAP reconciliation. Please see also note 35.5.a) of the Company’s audited consolidated financial statements as of and for the years ended December 31, 2009 and 2008.

Organization costs: under Central Bank Rules, the Company records under this item cost inherent to the set up and organization of the Bank. Under ASC 720-15, these organization costs are expensed. Please see also note 35.5.c) of the Company’s audited consolidated financial statements as of and for the years ended December 31, 2009 and 2008.

Additionally, as described in the Company’s audited consolidated financial statements as of and for the years ended December 31, 2009 and 2008 (see notes 4.4.o) and 27), “Provision for losses on other receivables and other allowances” mainly includes expenses related to contingent liabilities for probable claims, lawsuits and other proceedings, including those related to labor and other obligations. The amounts have been accrued in accordance with Central Bank Rules, which are similar to ASC 450 “Contingencies”.

The Company takes note of the Staff´s comment and will review future filings to include cross references in note 31 to the notes mentioned in previous paragraphs and vice-versa.

5. Please tell us and revise future filings to provide a discussion of your accounting policy for repurchase agreements and how it complies with US GAAP. Discuss whether you record these transactions as sale or as secured financings and, in each case, how you determined the appropriateness of your accounting.

With regard to the Company’s repurchase agreements, the Company determined that Central Bank Rules are similar to ASC 860. As a consequence, the Company recorded all of those agreements as secured financings and there is no difference under US GAAP. There are no agreements that would qualify for sales under applicable accounting policies.

6. Please tell us and revise future filings to disclose why it is more likely than not that you will not realize a portion of your deferred tax assets such that a valuation allowance is required. Clearly disclose how you determined the amount of the valuation allowance that was required at each balance sheet date.

In accordance with ASC 740-10-30-16 through 30-25, the Company evaluates for each consolidated entity all available evidence, both positive and negative and the future realization of the tax benefit over a relatively short period of time (considering future reversals of existing taxable temporary differences, future taxable income exclusive of reversing temporary differences and carryforwards and tax-planning strategies). The Company considers using future projections of income for only relatively short periods of time to be a reasonable approach, given Argentina's history of economic volatility.

In determining the amount of the valuation allowance for deferred tax assets required at each balance sheet date, the Company applies ASC 740 as mentioned in note 35.1. to the Company’s audited consolidated financial statements as of and for the years ended December 31, 2009 and 2008. At each balance sheet date and since the Initial Public Offering, the Company has applied the same policy.

7. Please provide us with a schedule that presents securities available for sale in a tabular format that reconciles them to the balance sheet in footnote 31 and that includes the disclosure requirements of ASC 320-10-50-2. Similarly, please address the disclosure requirements of ASC 320-10-50 sub paragraphs 6 and 7. Revise future filings to include this information.

The following tabular format reconciles securities classified as available for sale (note 35.2. to the Company’s audited consolidated financial statements as of and for the years ended December 31, 2009 and 2008) to the balance sheet under Central Bank Rules (note 31) and includes the disclosure requirements of ASC 320-10-50-2:

In addition, as of December 31, 2009 the unrealized losses were not significant.
