Triffin’s Dilemma: The Privilege and The Curse of the Dollar As World Currency
Posted on: March 28, 2025
Following our series about academic research, today I will write about Triffin’s Dilemma, a theory proposed by Dutch economist Robert Triffin in the 1960s.
The theory postulates that the country that owns the world’s reserve currency will inevitably face a persistent trade deficit that will imperil the confidence in that currency.
The theory was originally tied to the Bretton Woods Accord after World War II, where the US dollar was pegged to gold, and the rest of the world’s were pegged to the dollar. In 1971, President Nixon announced the de-pegging of the dollar from gold, effectively, making the dollar a fiat currency that the government could “print” as much of as they wanted.
This is an exorbitant privilege that other countries do not enjoy. By this, I mean that no matter what problems our country faces, we can print our way out of trouble. The oversupply of the dollar would normally cause hyperinflation in our country, but since ours is the world currency, we can export our surplus dollars to the rest of the world by running a trade deficit.
Exporting dollars is a great business to have, since instead of goods, which requires costly manufacturing, dollars can be created by simply adding an entry into the Fed’s computer system. However, a side effect is, that nobody wants to invest in manufacturing and no young people want to work in factories. All smart kids want to be in finance, the industry that is closely related to money creation, allocation, and management. This has led to overfinancialization and the gradual deindustrialization of the country (See chart below.)

The authors, Narasimham Jegadeesh and Sheridan Titman, studied whether there is persistent money to be made by buying winners and selling losers, otherwise known as the momentum strategy. If the answer is yes, what is the best way to execute it?
They found that if one buys a portfolio of winners (stocks with the top decile returns in the previous 12 months) and sells a portfolio of losers (stocks with the bottom decile returns in the previous 12 months), and holds that for 3 months, one can achieve a return of 1.49% per month on paper. This is huge! This level of monthly returns translates into nearly 18% annual return.
Throughout my 20 years of giving financial advice, I have noticed that amateur investors love momentum strategy, while more mature investors shun it because they have learned the caveats.
So what are the caveats?
