Ladies and Gentlemen:

We are writing to you on behalf of the CurrencyShares Trusts identified above (each, a ‘‘Trust’’), each sponsored by Rydex Specialized Products LLC d/b/a Rydex Investments (the ‘‘Sponsor’’).

We confirm that we have been advised by the Sponsor that the analysis employed by the Sponsor in determining the functional currency for the British Pound Sterling Trust, described in our letter dated May 8, 2006 (in response to comment number 19 in the comment letter of the staff of the Division of Corporation Finance dated April 17, 2006) is the same analysis used to determine the functional currency of each Trust. As such, the Sponsor has determined that the functional currency for CurrencyShares Australian Dollar Trust is the Australian Dollar, for CurrencyShares Canadian Dollar Trust is the Canadian Dollar, for CurrencyShares Mexican Peso Trust is the Mexican Peso, for CurrencyShares Swedish Krona Trust is the Swedish Krona and for CurrencyShares Swiss Franc Trust is the Swiss Franc.

Please contact the undersigned at (313) 234-7107 should you have any questions or comments.

Very truly yours,

/s/ Yvette M. VanRiper
