Internationale Liquidität — Summary

Fritz Machlup’s Internationale Liquidität is a compressed German conference intervention that responds to Teschner while developing its own critique of international monetary reform after Bretton Woods. Machlup treats “international liquidity” less as a slogan than as a set of distinguishable problems: reserve adequacy, exchange-rate adjustment, gold, and the institutional meaning of Special Drawing Rights. The lecture’s force lies in its refusal to let a fashionable term conceal analytical confusion.

Machlup first resists any monocausal account of Bretton Woods. Excessive reserves may have delayed adjustment, but the dollar system also failed because American gold holdings became increasingly inadequate relative to outstanding liabilities. The collapse was therefore not simply a story about too much liquidity, but about unstable commitments and postponed correction.

Die ständige Schrumpfung der Goldreserven der Vereinigten Staaten im Verhältnis zu ihren laufenden Verbindlichkeiten hat auch zum Zusammenbruch beigetragen.

English translation: The continual shrinkage of the gold reserves of the United States in relation to its current liabilities also contributed to the collapse.

This leads to his skepticism about “equilibrium” exchange rates. In the shortest run, equilibrium has a determinate meaning: it is the free market price. Beyond that, Machlup treats the long-run equilibrium rate as a counterfactual construct requiring impossible knowledge about unchanged future conditions.

Wenn man ganz kurzfristig denkt, so ist der Gleichgewichtskurs der freie Marktpreis.

English translation: If one thinks strictly in the very short run, the equilibrium rate is the free market price.

The practical consequence is a critique of adjustable pegs changed only “when necessary.” Monetary authorities tend to assume that the existing rate is correct, and therefore recognize the need for adjustment later than markets do. A system that waits for official acknowledgment invites speculation, crises, and abrupt discipline rather than continuous adaptation.

Die Währungsbehörden sind in der Regel optimistisch und glauben immer, daß der gegenwärtige Kurs auch der richtige ist.

English translation: The monetary authorities are as a rule optimistic and always believe that the prevailing rate is also the correct one.

Machlup’s discussion of gold is similarly conceptual. He distinguishes demonetization from the mere selling of official gold stocks: gold is already demonetized in the decisive sense if new production and private dishoarding no longer automatically increase money through official purchase. Central-bank possession of gold does not by itself make gold a monetary standard.

His treatment of SDRs continues this effort to clarify institutional meaning. The original point of SDRs, for Machlup, was to create an unbacked reserve asset allocated to monetary authorities, not to reproduce older notions of “coverage” through dollars, sterling, securities, gold, loans, or development finance. Such alternatives might be administratively possible, but they would obscure the theoretical innovation.

Die Grundidee war, die Schaffung eines Reserveaktivums für Währungsbehörden durch Gratisverteilung.

English translation: The basic idea was the creation of a reserve asset for monetary authorities through free distribution.

The essay also narrows the inflated vocabulary of liquidity. “Liquidity” can be defined broadly enough to include credit lines, saleable assets, and imported material stocks net of obligations, but that breadth makes aggregate measurement nearly impossible. For operational analysis, Machlup argues, one is repeatedly driven back toward reserves, even though reserve adequacy itself cannot be captured by a single ratio to imports, money supply, payments deficits, or external liabilities.

In its final movement, the lecture surveys competing theories of optimal reserve volume and reserve growth, including welfare, employment, trade, inflation, and adjustment criteria. Machlup does not deny the need for rules or targets, but he emphasizes their indeterminacy when applied to real countries with divergent objectives. The enduring value of the piece is therefore methodological: it dismantles pseudo-precision in international monetary reform and asks what policy concepts actually measure, what institutional designs imply, and how adjustment pressures operate when political authorities delay recognition of disequilibrium.
