Michael Zezas: Welcome to Thoughts on the Market. I'm Michael Zezas, Morgan Stanley's Global Head of Fixed Income Research.

James Lord: I'm James Lord, Head of FX Strategy for Emerging Markets.

David Adams: And I'm Dave Adams, Head of G10 FX Strategy.

Michael Zezas: And on this episode of Thoughts on the Market, we'll discuss one of the most debated topics in world markets right now, the strength of the US dollar.

It's Wednesday, May 1st, at 3 pm in London.

Michael Zezas: Currencies around the world are falling as a strong US dollar continues its reign. This is an unusual situation. So much so that the finance ministers of Japan, South Korea, and the United States released a joint statement last month to address the effects being felt in Asia. The US dollar's dominance can have vast implications for the global economy and the world stock markets.

So, I wanted to sit down with my colleagues, James and David, who are Morgan Stanley's currency strategy experts for emerging markets and developed markets. James, just how dominant is the US dollar right now and what's driving the strength?

James Lord: So, we should distinguish between the role the US dollar plays as the world's dominant reserve currency and its value, which can go up and down for other reasons.

Right now, the dollar remains just as dominant in the international monetary system as it has been over the past several decades, whilst it also happens to be very strong in terms of its value, as you mentioned. That strength in its value is really being driven by the continued outperformance of the US economy and the ongoing rise in US interest rates, while growth in the rest of the world is more subdued.

The dollar's international role remains dominant simply because no other economy or market can match the depth of the US capital markets and the liquidity that it provides, both as a means of raising capital, but also as a store of value for investment; while also offering the strong protection of property rights, strong sovereign credit ratings, the rule of law, and an open capital account. There simply isn't another market that can challenge the US in that respect.

Michael Zezas: And can you talk a bit more specifically about the various ways in which the dollar impacts the global economy?

James Lord: So, one of the strongest impacts is through the price of the dollar, and the price of dollar debt, which have an impact beyond the borders of the US economy. Because the majority of foreign currency denominated debt that corporates outside of the US issue is denominated in US dollars, the interest rate that's set by the US Federal Reserve has a big impact on the cost of borrowing. It's also the same for many emerging market sovereigns that also issue heavily in US dollars. The US dollar is also used heavily in international trade, cross border lending, because the majority of international trade is denominated in US dollars. So, when US interest rates rise, it also tightens monetary conditions for the rest of the world. That is why the US Federal Reserve is often referred to as the world's central bank, even though Fed only sets policy with respect to the US economy.

And the US dollar strengthens, as it has been over the past 10 years, it also makes it more challenging for countries that borrow in dollars to repay that debt, unless they have enough dollar assets.

Again, that's another tightening of financial conditions for the rest of the world. I think it was a US Treasury Secretary from several decades ago who said that the US dollar is our currency, but your problem. And that neatly sums up the global influence the US dollar has.

Michael Zezas: And David, nothing seems to typify the strength of the US dollar recently, like the currency moves we're seeing with the Japanese Yen. It looks very weak at the moment, and yet the Japanese stock market is very strong.

David Adams: Yeah, weak is an understatement for the Japanese yen. In nominal terms, the yen is at its weakest level versus the dollar since 1990. And if we look in real terms, it hasn't been this weak since the late 1960s. Why it's weak is pretty easy to explain, though. It's monetary policy divergence. Theory tells us that as long as capital is free to move, a country can't both control its interest rates and control the exchange rate at the same time.

G10 economies typically choose to control rates and leave their currencies to float, and the US and Japan are no exception. So, while the while the Fed's policy rate has risen to multi-decade highs, Japan's has been left basically unchanged, consistent with its economic fundamentals.

Now, you mentioned Japanese equities, which is also increasingly important to this story. As foreign investors have deployed more cash into the Japanese stock market, a lot of them have hedged their FX [foreign exchange] exposure, which means they're buying back dollars in the forward market. The more that Japanese equities rise, the more hedges they add, increasing dollar demand versus the yen.

So, put simply, the best outcome for dollar yen to keep rising is for US rates versus Japan and Japanese equities to both keep marching higher. And for a lot of investors, this seems increasingly like their base case.

Michael Zezas: That makes sense. And yet, despite the dollar's clear dominance at the moment, the consensus view on the dollar is that it's going to get weaker. Why is that the case and what's the market missing?

James Lord: Yeah, the consensus has been on the wrong side of the dollar call for quite a few years now, with a persistently bearish outlook, which has largely been incorrect. I think for the most part this is because the consensus has underestimated the strength of the US economy. It wasn't that long ago when the consensus was calling for a hard landing in the US economy and a pretty deep easing cycle from the Fed. And yet here we are with GDP growth north of 2 per cent and murmurings of another rate hike entering the narrative. I also wonder whether this debate about de-dollarization, whereby the dollar's global influence starts to wane, has impacted the sentiment of forecasters a bit as well.

We have seen over the past three to four years much more noise in the media on this topic, and there appears to be a correlation between the extent to which the consensus is expecting dollar weakness and the number of media articles that are discussing the dollar's status as the world's major reserve currency.

Maybe that's coincidence, but it's also consistent with our view that the market generally worries too much about this issue and the impact that it could have on the dollar's outlook.

Michael Zezas: Now there've been a few notable changes to Morgan Stanley's macro forecasts over the last few weeks. Our US economist, Ellen Zentner revised up her forecast for US growth and inflation. And she also pushed back our expectations for the first Fed cut. Along with this, our US rate strategy team also revised their 10-year treasury yield expectations higher. Do these updates to the macro-outlook impact your bullish view on the dollar, both near term and longer term?

David Adams: So, higher US rates are often helpful for the dollar, but we think some nuance is required. It's not that US rates are moving; it's why they're moving. And our four-regime dollar framework shows that increases or decreases in rates can give us very different dollar outcomes depending on the reason why rates are moving.

So far this year, rates have been moving higher in a pretty benign risk environment. And in a world where US real interest rates rise alongside equities; the dollar tends to go nowhere in the aggregate. It gains versus low yielding funders like the Japanese yen, the Swiss franc, and the euro, but it tends to weaken versus those higher beta currencies with positive carry, like the Mexican peso. It's why we've been neutral on the dollar overall since the start of the year, but we still emphasize dollar strength, especially versus the euro.

If rising rates were to start weighing on equities, that would lead the dollar to start rallying broadly, what we call Regime 3 of our framework. It's not our base case, but it's a risk we think markets are starting to get more nervous about. It suggests that the balance of risks are increasingly towards a higher dollar rather than a lower one.

Michael Zezas: And finally, Dave, I wanted to ask about potential risks to the US dollar's current strength.

David Adams: I'd say the clearest dollar negative risk for me is a rebound in European and Chinese growth. It's hard for investors to get excited about selling the dollar without a clear alternative to buy. A big rebound in rest of world growth could easily make those alternatives look more attractive, though how probable that outcome is remains debatable.

Michael Zezas: Got it. So, this discussion of risk to the strong dollar may be a good time to pause. There's so much more to talk about here. We've barely scratched the surface. So, let's continue the conversation in the near future when we can talk more about the dollar status as the world's dominant reserve currency and potential challenges to that position.

James Lord: This sounds like a great idea, Mike. Talk to you soon.

David Adams: Likewise. Thanks for having me on the show and look forward to our next conversation.
