The facts are amply stated in the very able opinion of Judge Rifkind, D.C., 58 F. Supp. 623. We agree with that opinion.
We do not, however, entirely agree with the trial judge with respect to the interest. See D.C., 60 F.Supp. 103. He held that interest on the deposits should be computed at the contracted rates up to June 16, 1933, the effective date of the Banking Act of 1933, § 11(b), 12 U.S.C.A. § 371a, prohibiting the payment of interest on demand deposits by member banks of the Federal Reserve System; and that interest, after the date when the actions were commenced, should be computed at 4%. We accept these conclusions, except as to the 4% rate.
The judge reasoned thus: (1) Had the suits been brought by the depositor, the Russo-Asiatic Bank, or by the Russian Government, the rate, after breach, would have been at 6%, this being the rate prescribed by the New York statutes as to contracts made and to be performed in New York. (2) But, because the claims had been transferred to the United States, Royal Indemnity Co. v. United States, 313 U.S. 289, 296, 61 S.Ct. 995, 997, 85 L.Ed. 1361, applied, and required the determination of the interest as damages for delay, regardless of the local statute.
We think the Royal Indemnity case in-apposite. There a federal collector of internal revenue had accepted a surety bond filed with him by a taxpayer to accompany a claim for abatement of income tax. The Commissioner of Internal Revenue in part rejected the abatement claim and demanded the unpaid amount of the tax, together with interest. The taxpayer did not pay the interest. In a suit against the surety for the interest, the Court held that “the rule governing the interest to be recovered as damages for delayed payment of a contractual obligation to the United States is not controlled by state statute or local common law. In the absence of an applicable federal statute it is for the federal courts to determine, according to their own criteria, the appropriate measure of damage, expressed in terms of interest, for nonpayment of the amount found to be due.” The Court cited Board of County Commissioners v. United States, 308 U.S. 343, 350, 352, 60 S.Ct. 285, 84 L.Ed. 313. There the United States brought suit, on behalf of an Indian, for recovery of taxes paid to a county. The law of the state precluded recovery of interest on taxes illegally collected. The Court (308 U.S. 350, 60 S.Ct. 288) said, “In ordinary suits where the Government seeks, as between itself and a private litigant, to enforce a money claim ultimately derived from a federal Irnvp- * * * this Court has chosen that rule as to interest which comports best with general notions of equity.” As to interest on the claim in question, the Court held that the state law was inapplicable, stating that, in such cases, “the state law has been absorbed, as it were, as the governing federal rule not because state law was the source of the right but because recognition of *573state interests was not deemed inconsistent with federal policy.” We think, therefore, that the Royal Indemnity doctrine must be limited to suits to enforce money claims “ultimately derived from a federal law.1 This interpretation is borne out in subsequent cases in which the Royal Indemnity case has been cited. Thus it was cited in Prudence Corporation v. Geist, 316 U.S. 89, 95, 62 S.Ct. 978, 982, 86 L.Ed. 1293, to support the proposition that in “the interpretation and application of federal statutes, federal not local law applies.” So, too, it was cited in Clearfield Trust Co. v. United States, 318 U.S. 363, 366, 63 S.Ct. 573, 575, 87 L.Ed. 838, which related to “the rights and duties of the United States on commercial paper which it issues.”2
In the instant case, the claims did not “ultimately derive from a federal law” or from a contract made between the bank and the United States. Here the United States is, in effect, an assignee of the Russian government which, in turn, acquired the claims from the defendant’s depositor. The rights thus derive from contracts made between that depositor and the defendant. Accordingly, we hold that the state statute governs and that the proper rate of interest from the date of the breach was 6%.
The United States argues that the breach occurred at least as early as 1918, when the defendant, by entries on its books, purported to assert that it no longer owed anything on account of the deposits. We cannot agree. As the deposits were debts payable on demand, nothing was due and payable until a demand. We agree with the trial judge that the demand of the refugee directors of the Russo-Asiatic Bank was not effective.3 Accordingly, no effective demand was made until the United States instituted the present actions.4
It has been held in New York that a trustee or other fiduciary may be liable for conversion of money, even if it is not earmarked.5 This seems to us to be the explanation of cases cited by the United States,6 for, in each of those cases, the bank appears to have knowingly participated in or aided such a‘conversion,7 and in New York the rule is that interest is allowed as a matter of right in cases of conversion.8 We find no New York de*574cisions to the effect that, absent any fiduciary relation or participation in a fiduciary’s breach of his obligation, a bank is guilty of conversion merely- because it makes entries on its books showing a cancellation of all or any part of its obligations to a general depositor, when the fact of such conduct has not been communicated to the depositor.9
