The markets reacted heavily to the news. The US 10-year yield fell sharply, while the 30-year yield dropped from its highest levels since 2007. The latter helped support equity valuations: the S&P 500 eked out a small 0.21% gain but remained short of reversing the chip rout. VanEck’s semiconductor ETF lost 1.55% regardless. The US dollar tanked, letting the majors rally aggressively against the greenback.

This morning, we see US bonds and FX consolidate, as investors question what the Treasury announcement really means and what its longer-term impact could be.

First, it’s important to note that US national debt has crossed the $40 trillion mark. Interest payments have become one of the biggest items in the federal budget, while persistent deficits mean that the US continues to add debt as its interest bill grows. And fiscal policy under Trump is not improving the picture. Instead of restricting policy and raising taxes, the Trump administration favours lower taxes and tries to fill the gap through spending cuts and tariff revenues.

As such, the US fiscal picture today remains as murky (if not murkier) as yesterday, but the way the government is willing to manage its debt – and the weight of the Federal Reserve (Fed) in the picture – has changed.

In the short run, the impact is relatively straightforward. Buying back more long-dated debt should ease pressure on longer-term yields, helping households through lower mortgage rates and corporations through lower borrowing costs. That’s positive.

For the dollar, lower long-term yields are initially negative, as they reduce the attractiveness of US assets to international investors. That's partly why the dollar sold off so aggressively yesterday.

But the operation changes neither the amount of US debt nor the underlying fiscal problem. And if Treasury increasingly relies on shorter-term borrowing, that would mean more frequent refinancing.

If rates remain high – uh-humm, there you’ve got to get the Fed to play along – the government's interest bill adjusts more quickly.

And that's where the longer-term risk lies. If investors conclude that Washington is increasingly trying to manage long-term borrowing costs rather than addressing the fiscal deficit itself, they could eventually demand a higher term premium to hold long-dated Treasuries. That could push long-term yields higher again.

And if investors start believing that the Fed is becoming a ‘sock puppet’ of the White House to keep rates lower and tame pressure on borrowing costs, the Fed would lose credibility, making the entire yield curve harder – not easier – to control.

So the Treasury may have found a way to buy some time and ease pressure on the longer end of the US yield curve, but not solve the problem. Near term, the move could help cap long-term yields and weigh on the dollar; longer term, without fiscal consolidation, it won’t eliminate the exploding debt risks or the underlying upward pressure on the yield curve.

Elsewhere...

Looking elsewhere, inflation figures from the euro area and the UK painted an unideal picture. In the UK, producer price pressures eased in July, partly due to the retreat in energy prices, but consumer prices came in hotter than expected due to a 13% rise in the energy price cap.

Across the Channel, euro-area inflation printed numbers that remain well above the European Central Bank’s (ECB) 2% target. Worse, price pressures could move higher in the coming readings as the July retreat in energy prices proved temporary. With no easy resolution in the Middle East, inflation risks remain tilted to the upside.

If we compare the US, UK and euro area, and their central banks’ policy stance regarding inflation, the ECB stands out as the most disciplined in its fight against inflation. The Bank of England (BoE) would also want to avoid an overheating in inflation, but the UK’s economic outlook remains bleak despite a surprisingly stronger-than-expected first half.

Weak jobs data earlier this week warned that Burnham’s pending first budget and the Middle East headwinds make the BoE less likely to act as forcefully as the ECB to fight inflation.

As for the Fed, yesterday’s FOMC minutes showed that many officials believed higher rates could be needed if inflation failed to decline. But the Fed’s reaction function and policy outlook are getting cloudier by the day, while concerns about political pressure under its new Chair Kevin Warsh add another layer of uncertainty.

So if we list the USD, euro and sterling in terms of the expected discipline of their central banks’ monetary policies, I would say that the euro keeps the top position, followed by sterling and the dollar. The latter should keep the euro and sterling bid against a broadly unloved US dollar.

Gold – which has come under pressure from rising global yields since August 10 – also has the potential to extend gains if global risk sentiment worsens and encourages capital flows into perceived safe-haven assets.

Today, shifting allocations toward sovereign and corporate bonds makes sense, but maintaining exposure to gold also gives a portfolio a hedge against inflation, exploding sovereign debt and geopolitical risks.
