Opening frame: What’s driving markets? Market take

Camera frame
Moody’s U.S. debt downgrade has reignited concerns — but we still see U.S. assets as central to global portfolios.

Title slide: U.S. risk assets still core to portfolios

1: U.S. asset performance
U.S. equities have surged 22% from their April lows, according to LSEG. Tech stocks have led the gains, affirming our preference for the AI theme.

When equities slid, so did the U.S. dollar and Treasuries - triggering speculation that investors are losing faith in U.S. assets. It’s not that simple.

The dollar is still historically strong. And we have long argued that investors would demand more compensation for holding long-term U.S. bonds – because of persistently large fiscal deficits, sticky inflation and bond volatility. Plus, long-term Treasuries still carry a relatively low risk premium versus the past.

The tariff-driven inflation and quarterly contractions we expect this year are akin to past periods when the dollar fell and term premium rose, and investors didn’t question U.S. assets more broadly then.

We stay overweight U.S. stocks on a six-to-12-month horizon, thanks to U.S. corporate strength and mega forces – big structural shifts like AI – that are driving an economic transformation on par with the industrial revolution.

2: Why long-term investing is harder now
We are publishing multiple sets of long-run capital market assumptions for the first time to reflect a wider range of potential outcomes and be more dynamic in building portfolios. We build our strategic allocations around a starting point scenario. But we now formally track alternative paths — so we’re ready to pivot portfolios should those scenarios unfold.

3. Our latest strategic views
We believe the starting point has to reflect today’s reality of global capital markets – with U.S. assets core to portfolios. Why? Hard economic rules limit how quickly the current structure can change. Supply chains can’t be rewired overnight — as the recent 90-day pause on U.S.-China tariffs shows. And the U.S. still depends on stable foreign funding to sustain its debt. Moody’s downgrade highlights the risk that persistent deficits and higher interest costs could dent confidence among foreign bondholders, pushing yields even higher. That’s why our starting point also includes our expectation of rising term premium for U.S. Treasuries and persistent inflation.

Outro: Here’s our Market take
Economic transformation makes building long-term portfolio construction more challenging. We now use a starting point scenario in our strategic views and formally track others. U.S. assets are still core to portfolios, in our view.

U.S. assets still favored

Moody’s U.S. debt downgrade highlights key challenges. We weigh long-term scenarios but still see U.S. assets playing a core role in global portfolios.

Market backdrop

U.S. stocks rose 2% last week after a tech driven rally, with the S&P 500 up 22% from its April lows. U.S. 10-year Treasury yields ticked up on the week.

Week ahead

This week we watch global flash PMIs for early signs of the business sentiment impact of U.S.-China trade de-escalation. Yet the data will likely remain volatile.

U.S. stocks have soared after sliding with U.S. bonds and the dollar last month. That joint drop stoked talk of U.S. assets losing their long-term appeal. Moody’s U.S. rating cut reinforces our long-held view that investors would want to see a rise in today’s relatively low compensation for the risk of holding long-term U.S. bonds. We still see U.S. assets as core to portfolios. The uncertain outlook means we cannot have conviction in one central scenario alone in our strategic views.

U.S. dollar can fall again

The chart shows that during past periods of stagflation and recession, the dollar weakened and term premium rose.

U.S. stocks have jumped 22% from their April lows, according to LSEG data, after the U.S. policy-driven selloff. Tech stocks have led the gains, reinforcing our preference for the artificial intelligence (AI) theme. Yet when equities slid, so did the U.S. dollar and Treasuries – spurring talk of investors losing confidence in U.S. assets. We don’t think that’s the case. The dollar is still historically strong. And we have long argued that investors would want more term premium, or compensation, for holding long-term U.S. bonds given persistently large fiscal deficits, sticky inflation and bond volatility. And long-term Treasuries still carry a relatively low risk premium versus the past. The tariff-driven inflation and quarterly contractions we expect this year are akin to past periods when the dollar fell and term premium rose, and investors didn’t question U.S. assets then. See the chart.

We stay overweight U.S. stocks on a six- to 12-month tactical horizon thanks to U.S. corporate strength and mega forces – big structural shifts like AI that are driving an economic transformation on a par with the industrial revolution. The end state of that transformation is unknowable, making longer-term asset allocation extremely challenging. We can no longer anchor views around a single base case and, as we’ve long argued, static allocations don’t work in the post-pandemic world. That is why we’re developing multiple sets of long-run capital market assumptions for the first time. We build our strategic allocations around a starting point scenario but now formally track others so we know how we would pivot portfolios should they come to fruition. This will allow us to move quickly as we learn more about how the transformation is evolving.

Our strategic starting point

What is our starting point scenario for our strategic views? We believe it has to be the current structure of the global capital market – with U.S. assets still core to portfolios. That’s because hard economic rules limit how quickly the structure can change. The recent 90-day pause on many U.S.-China tariffs illustrates one such rule: Supply chains can’t be rewired quickly without disruption. Moody’s decision to downgrade the U.S. government’s top-notch credit rating last week shines a light on a second rule: keeping U.S. debt sustainable relies on large and steady funding by foreign investors. The downgrade reinforces the U.S. fiscal sustainability challenge that we've long flagged, especially persistent U.S. budget deficits at a time when higher interest rates are boosting debt servicing costs. If these dynamics dent the confidence of foreign bond holders, rising term premium could push up bond yields and debt servicing costs even more.

That’s why our starting point also includes our expectation of rising term premium for U.S. Treasuries and persistent inflation pressure. We go overweight inflation-linked bonds and neutral global investment grade credit given wider spreads. We lean into private markets and like infrastructure equity, such as stakes in airports and data centers, as it benefits from mega forces. Private markets are complex and not suitable for all investors. We keep this scenario under review as we learn more.

Our bottom line

Economic transformation makes long-term portfolio construction more challenging. We now use a starting point scenario in our strategic views and formally track others. U.S. assets are still core to portfolios, in our view.

Market backdrop

The S&P 500 rose 2% last week in a tech-led recovery after policy-driven pullbacks in April. That put the index 22% above its April lows. U.S. 10-year Treasury yields ticked up to 4.45%, up more than 50 basis points since early April. Market are pricing in two rate cuts by the Federal Reserve for the rest of the year. U.S. CPI data for April showed easing wage pressures and don’t yet reflect the tariff impact. Yet we think the tight labor market will keep inflation sticky, limiting how much the Fed can cut.

This week, we’re watching global flash PMIs for May for any signs of improvement following the 90-day pause on U.S.-China tariffs. Trade and inflation data from Japan and the UK should shed light on how the U.S. tariff shock is rippling out to the rest of the world.

Week ahead
