Morning Brew August 20 2026

Good morning.

The main story this morning is still the bond market. U.S. debt has now officially moved above USD 40 trillion, and the long end of the Treasury curve remains the place where markets are asking the hardest questions about fiscal sustainability, inflation risk and the true cost of capital.

A surprise U.S. Treasury buyback announcement helped calm the latest rise in long-term yields, with the Treasury doubling long-end buybacks to at least USD 4 billion per operation. That was enough to stop the immediate pressure, but not enough to change the bigger picture. The amount is small compared with a Treasury market of more than USD 32 trillion.

The message is clear: the U.S. administration would like yields to be lower, but that is difficult when debt is above USD 40 trillion and investors are focused on supply, inflation and the term premium. Yesterday’s roughly 10-basis-point fall in yields was welcome, but it does not change the fact that long yields are still up around 50 basis points this year and roughly 410 basis points since 2020.

Key points:

• Capital is facing more competition. Governments, AI investment, defence and infrastructure are all drawing on funding at the same time, potentially keeping the cost of capital structurally higher.
• The reason yields are rising matters. If higher long-term yields increasingly reflect fiscal risk, heavy bond supply or a higher term premium — rather than simply stronger US growth — they may be less supportive for the US dollar than in previous cycles.
• Portfolio leadership could broaden. We think investors may increasingly differentiate in favour of strong cash generation and balance sheets, while income, gold and broader geographic diversification could play a larger role alongside structural growth themes.

Wall Street managed to finish slightly higher despite the nervous bond backdrop. The Dow gained 0.22%, the S&P 500 rose 0.21%, and the Nasdaq added 0.16%, helped by lower volatility and a modest retreat in yields. Europe was more mixed: the Stoxx 600 slipped for a sixth consecutive session, while the DAX edged lower, the FTSE 100 gained slightly, and the Swiss Market Index rose 0.5%.

In single names, Moderna surged after announcing that its personalised mRNA cancer therapy developed with Merck reduced the risk of melanoma recurrence and spread in a late-stage trial. Merck also rallied strongly, becoming one of the best performers in both the Dow and the S&P 500.

Meta remains under legal pressure after a former engineering director testified that child safety was treated as secondary to growth and engagement on Facebook and Instagram. The trial is worth watching because it could become another regulatory overhang for the major platform companies.

In FX, the dollar sold off after the Treasury buyback announcement helped reverse the long-end yield spike. The Bloomberg Dollar Spot Index fell as much as 0.8% to its weakest level since May. USD/JPY is back around 158.70 after yesterday’s drop, while USD/CHF was the standout G10 move, with the franc delivering its sharpest one-day rally since July. EUR/USD is around 1.1675 and GBP/USD near 1.3608.

Gold and silver recovered strongly after looking fragile earlier in the week. Gold is testing the key 4,500 resistance area, while silver is trading just above 67. The direction from here will likely depend on whether yields stay contained or whether the bond market starts pushing back again.

The July FOMC minutes showed that most officials favoured holding rates steady, although several still wanted a hike and warned that more tightening may be needed if inflation remains high. The committee highlighted tighter financial conditions, broad-based price gains and an outlook of similar inflation but slightly weaker growth. Kevin Warsh also floated the idea of cutting the number of Fed meetings to six per year, although there is no change planned for 2026.

Geopolitics remain part of the backdrop. Trump warned that any country allowing its financial institutions, businesses, airports or government entities to provide a lifeline to Iran would face “tremendous economic consequences”. With approval ratings under pressure, the risk of headline-driven escalation remains high.

Today’s focus will likely remain on yields, with only a modest macro calendar. Walmart earnings will be closely watched as one of the most important reads on the U.S. consumer, while traders will also keep an eye on the 200-day averages in USD/JPY and gold. The Swiss franc is worth watching as well: if yen volatility stays elevated, CHF could become a more attractive funding currency for carry trades, especially with the Swiss 10-year yield around 0.39% versus Japan near 2.84%.

Trade safely.
