Felix Somary: Review of Heyn, Arnold, and Bothe on Indian Currency Reform (1907)

Felix Somary’s comparative review examines three monographs on Indian currency reform, using their differences to test explanations of monetary stabilization and its economic consequences. Otto Heyn supplies original theoretical deductions, Anton Arnold combines historical breadth with close attention to economic practice, and M. Bothe reconstructs the reform’s successive phases. Somary’s central judgment is that the reform proved predominantly beneficial, but that neither its causes nor its effects can be understood through exchange-rate movements alone.

The review begins with the fiscal and financial pressures behind reform. Rupee depreciation increased the domestic cost of servicing debt held in England, discouraged foreign capital, and impaired trade through exchange-rate instability. India’s predominantly agrarian economy obtained only limited export advantages from depreciation. These pressures led the government to close the mints to free coinage and offer rupees against gold at a fixed rate. Although the rupee’s value was detached from its silver content, the intended exchange rate did not immediately hold. Somary therefore makes the subsequent appreciation of the rupee the review’s principal theoretical problem.

Heyn explains appreciation through the scarcity of rupees on the world market, rejecting domestic monetary contraction as a sufficient explanation. His argument distinguishes goods consumed domestically, whose prices contraction would depress, from exports governed by world-market conditions. Somary challenges the rigidity of this distinction: rice and wheat enter both domestic and foreign consumption, while cheaper raw materials and subsistence goods can reduce export production costs. He allows that capital flight might initially depress the exchange rate, but argues that monetary scarcity could subsequently support it; the favorable balance of payments nevertheless remained the chief cause. His admiration for Arnold does not prevent criticism of its limited engagement with this question:

Nach den feinen Erörterungen Heyns wäre eine eingehende Auseinandersetzung geboten gewesen.

English translation: After Heyn's subtle discussions, a thorough engagement with the matter would have been called for.

The passage establishes Somary’s comparative standard: empirical mastery must be accompanied by direct engagement with a rival’s strongest theoretical claims. The review then turns from the mechanism of appreciation to the reform’s consequences, emphasizing the difficulty of isolating them:

Ursachen und Wirkungen der Reform hängen innig miteinander zusammen, und darum läßt sich die Darstellung beider schwer trennen; freilich ist die Entwicklung der Ursachen leichter als jene der Wirkungen, die ja zum Teil noch nicht überblickt werden können.

English translation: Causes and effects of the reform are intimately connected with one another, and for that reason the presentation of the two can hardly be separated; admittedly the development of the causes is easier than that of the effects, which in part cannot yet be surveyed.

Fiscal gains are clear, but effects on public credit cannot be distinguished confidently from the simultaneous crisis in the English money market. Short-term capital movements and the placement of bank and railway shares became easier, without a corresponding improvement in capital provision for agricultural industry. Somary thus resists treating monetary stabilization as a uniform benefit across sectors.

Foreign trade brings the contrast between Heyn and Arnold into sharpest focus. Heyn calculates the burden appreciation would impose on exporters; Arnold examines actual outcomes, including forces that offset the currency change. Lower freight charges sustained rice exports, while changing London tastes favored Indian tea despite the exchange-rate advantage accruing to Chinese tea. Somary accepts Heyn’s counterfactual question—what would have happened without appreciation—but insists that policy assessment must also explain what actually occurred:

Daß Heyn an der Betrachtung der tatsächlich eingetretenen Wirkungen vorübergleitet, ist wirklich ein Mangel; gerade die Berücksichtigung dieses Momentes bildet einen Glanzpunkt des Buches von Arnold.

English translation: That Heyn glides past the consideration of the effects that have actually occurred is really a defect; it is precisely the attention paid to this factor that constitutes a high point of Arnold's book.

This distinction carries a practical argument: reform should be timed so that other economic developments cushion its disruptive effects. Currency changes operate through transport costs, input prices, consumer preferences, and capital flows, not independently of them. Cheaper raw materials protected industrial exports, although coal, cotton, and especially opium suffered export-inhibiting effects.

Im allgemeinen aber ist die Wirkung der Reform überwiegend günstig gewesen.

English translation: In general, however, the effect of the reform has been predominantly favourable.

Somary closes by preserving the distinct merits of all three studies. Heyn’s ingenuity gives his arguments significance beyond the Indian case; Bothe’s careful historical account supplies valuable source material; Arnold’s command of practice earns the highest overall praise. The review’s broader relevance lies in its disciplined conjunction of monetary theory, historical evidence, and policy judgment: a defensible account of reform must distinguish an isolated exchange-rate effect from the economic outcome produced by several interacting causes.
