Why the dollar's wobble could be self-perpetuating

LONDON, May 29 (Reuters Breakingviews) - Foreign currency hedging is not a topic that usually dominates the water-cooler chats on trading floors. Right now, however, it's front of mind for many of the biggest players in financial markets. The U.S. dollar's unusual moves in April, when it fell in tandem with stocks, has cast doubt over a long-lasting relationship between the greenback and risky assets. Over time, it might nudge non-U.S. investors to hedge more or reduce their exposure to American stocks and bonds. Both could create a self-reinforcing downward cycle for the dollar.
Investing abroad is a tricky business for money managers with liabilities denominated in the currency of their home country. Think German or Japanese insurers, whose policies are written in euros and yen, or Canadian and Australian pension funds, whose beneficiaries expect to finance their retirement in Canadian and Aussie dollars. Buying shares and debt issued by companies in other countries introduces the danger that foreign exchange swings will reduce the value of the investments in local-currency terms, even if the underlying returns are good. That is why investors tend to use foreign exchange forwards and other derivatives to hedge currency risks, effectively swapping far-flung exposures into domestic ones.
The beauty of holding U.S. assets, though, is that the dollar tends to strengthen when the market panics. In money-manager speak, it's an anti-cyclical currency, which means investment bosses can get away with minimal protection against foreign exchange risk on giant portfolios of American stocks and bonds. It also helps that the dollar has generally risen in recent years, providing foreign investors with an extra boost to their overall returns.
One study, opens new tab, published by the National Bureau of Economic Research, found that foreign insurers, pension funds and mutual funds hedged 44%, 35% and 21% of their respective dollar portfolios in 2020, with much higher ratios for bonds compared to stocks. Apply that range to the $30 trillion of total American assets held by non-U.S. investors as of last year, and the implication is that anywhere between $24 trillion and $17 trillion could be unhedged.
Take the Canada Pension Plan Investment Board for example. U.S. dollar exposures account, opens new tab for more than half of its net investments of $520 billion, but are minimally hedged, according to a person familiar with the portfolio. Several people involved in the running of different Canadian retirement funds told Breakingviews that the safe-haven nature of the greenback was a key reason for relatively low hedge ratios. Japan's giant Government Pension Investment Fund, meanwhile, had invested almost a third of its $1.7 trillion portfolio in American assets as of March 2024 with slightly more than half in stocks and the rest in bonds. The U.S. exposure was almost entirely unhedged, a person familiar with the matter told Breakingviews.
According to traders and analysts these large so-called 'open' positions in U.S. assets have caught the attention of currency market players in recent months, for two reasons. First, the dollar didn't live up to its safe-haven billing after U.S. President Donald Trump's tariff plan tanked stocks in early April. The greenback fell roughly 5% against a basket of other rich-world currencies and failed to rebound alongside the S&P 500 Index when trade tensions cooled. The upshot for foreign investors is that volatile U.S. policymaking may cause the dollar to gyrate in the same way as equity markets. If that becomes the norm, foreign investors' risk models would over time call for much more dollar hedging.
The second consideration is that Trump and his advisers seem set on weakening the currency in a bid to boost exports. That is cementing a sense in foreign currency markets that the dollar is unlikely to see another 2022-style surge in strength, meaning overseas investors may be more likely to get a drag from the greenback rather than a lift.
One open question is whether it is even possible for large pension funds and insurers to meaningfully increase the proportion of their dollar portfolios that are hedged. In places where local institutions' holdings of U.S. assets are large relative to the local market, such as Taiwan or Nordic countries like Sweden, a big increase in demand for FX derivatives could meaningfully affect the value of the domestic currency. The Taiwan dollar's recent surge against the greenback looks like a case in point.
Even in deeper markets like the Japanese yen, euro or Canadian dollar, hedging comes at a price. The typical method is to use forward contracts, which involves locking in an exchange rate by agreeing to buy one currency and sell another at a future date. The cost is largely determined by the difference in government bond yields between the two markets. Relatively high U.S. interest rates therefore make it expensive for local investors to hedge their dollar exposure.
One-year contracts currently imply a roughly 2% annual cost for Canadian and European investors and 4% for those in Japan, according to Breakingviews calculations. The implication is that institutions which hedge an extra quarter of their U.S. portfolio could reduce returns by 0.5 percentage points to 1 percentage point, all else being equal. That raises the bar for holding American assets relative to home-country ones.
The alternative to extra hedging is for big institutional investors to shrink their exposure to the U.S., for example by investing the marginal euro, yen or loonie elsewhere. Pension managers and insurers generally take months or years to change their investment policies, meaning any shift won't be immediate. Yet there are signs that both may already be happening in a small way. Traders and investors say the recent slide in the dollar is partly due to extra hedging activity, which mechanically weakens the currency that is being hedged. Meanwhile, non-U.S. participation in a recent 30-year Treasury bond auction was the lowest since 2019, Reuters reported.
The danger, from a dollar holder's perspective, is that these trends reinforce one another. A weaker and more volatile greenback may inflict losses on foreign owners of U.S. assets, inducing them to sell or hedge more, in turn weakening the currency even further. At some point American assets might look cheap enough for global investors to pile back in – but not before the dollar falls further.
