The present intervention by the US Treasury to force down yields, and the warnings from a famed investor, set up an economic face-off that could affect global markets.
It is almost 34 years to the day since George Soros laid a then-enormous $10 billion bet that the British pound would weaken and exit the European Exchange Rate Mechanism. This era-defining trade, which is said to have netted Soros more than $1 billion in a single day, remains one of the outstanding macro trades ever made. It eventually forced the Bank of England to abandon its support for the ERM-defined pound exchange rate.
Soros’ reasoning was that the underlying macroeconomic situation in the participating countries could not remain broadly synchronised, as required by the ERM. Maintaining the ERM required participating countries, in effect, to give up monetary policy to the Bundesbank and possess the political and fiscal will to accept the mechanism’s possible negative consequences for domestic economies. Great Britain specifically faced a situation in which it needed either to increase interest rates or pursue deflationary policies, both of which would have damaged the domestic economy, with political consequences following soon afterwards. The bet was that Britain would choose to exit the ERM rather than stomach these consequences, a politically expedient solution to an economic problem.
A particularly Soros-esque part of the plan was his now-famous theory of reflexivity: large capital flows could bring about a self-fulfilling prophecy because of the scale made possible by leveraged trading.
Pound Lessons
Managing the trade for Soros were two now well-known figures in the investing world: Stanley Druckenmiller, the now-legendary investor, and Scott Bessent, the present US Treasury secretary. The former was a portfolio manager with the Soros funds and the latter an analyst who saw the economic instability within the ERM.
One would have thought that both would have internalised the idea that fighting enormous and potentially unlimited capital flows, when they are aligned with economic trends, is a losing proposition. Yet both now find themselves on opposite sides of another macro trade, one that could have enormous consequences for global markets.
The Trump administration’s desire for lower rates in the absence of an economic environment that supports them is already well known. His constant berating of Jerome Powell, the previous Fed chair, and his appointment of Kevin Warsh, who appeared to tilt towards lower rates during the run-up to the confirmation hearings, are clear evidence of this. So are his inexplicable public pronouncements that a strong economy such as the US should have lower rates. The recent debate over holding rates steady, even as US inflation stubbornly refuses to fall amid tariffs, the AI boom and asset-price inflation, suggests that this political bias for lower rates is working its way into policy.
Even more troublesome is the Treasury’s recent decision under Bessent to buy 10- to 30-year Treasury bonds regularly, citing perceived market mispricing, and fund the purchases through Treasury bill issuance. While the Treasury has intervened in the recent past, it has done so only to correct market failures, not to dictate yields to markets. The tiny initial intervention of a few billion dollars predictably did nothing. Bond yields fell for a day before recovering the next. The Treasury has upped the ante, stating that it will use the TGA, which funds the US government’s day-to-day expenses, as additional firepower. This is akin to using corporate cash balances for speculation.
Economics Trumps Intervention
Stan Druckenmiller has now openly described this as a misadventure in which a government is actively intervening to set market prices in perhaps the most liquid market in the world, one backed by enormous leveraged capital flows. In an op-ed for a newspaper, he criticised the intervention as one that simply cannot succeed, given the tremendous economic pressure for higher long-term rates, especially from the US fiscal deficit, which requires enormous government borrowing each year.
Implicit in this position is the belief that economics trumps intervention, consistent with the lessons from the British pound trade and other such bets during and after the Asian crisis. Perhaps he also understands reflexivity better than most, particularly the power of leveraged capital that can be brought to bear against ill-advised interventions.
As fascinating as the economic face-off is, equally fascinating is how the people behind it, having seen the same outcomes and cooperated on strategies to profit enormously from interventions unsupported by economic trends, have now taken opposite positions. Bessent and Druckenmiller were on the same side of the famed pound trade. They are now effectively facing off over the interest-rate intervention.
Coincidentally, the present Fed chair, Kevin Warsh, is also a former partner of Druckenmiller’s and presumably has seen his former mentor’s ideas and beliefs at close quarters. Though he still has some time to dispel this notion, his policies increasingly look like foot-dragging on raising interest rates and stand in stark contrast to what Druckenmiller and others on his policymaking committee are suggesting: that these policy moves do not hold up against the underlying economic trends.
What is clear is that there is a problem. Those who know the consequences of going against the economic grain appear to be abandoning logical positions for politically expedient ones, in an attempt to buy time. Druckenmiller, for his part, is simply an influential private citizen reminding them of this. Given the importance of the US Treasury market for global risk assets, this may have far-reaching consequences.
