What if the most revealing measure of Donald Trump’s elusive peace with Iran is no longer found in diplomatic statements or battlefield reports, but somewhere along the US Treasury yield curve?
That might sound an odd place to look for the consequences of a Middle Eastern war. Yet five months after the US and Israel attacked Iran, the bond market appears to be pricing yet another complication from a conflict whose economic spillovers keep travelling considerably further than its architects presumably intended. Oil is rising again, inflation anxiety has returned, long-dated Treasury yields are pushing towards uncomfortable territory and the Federal Reserve finds itself caught between political pressure and price stability.
So much for the peace dividend.
The immediate problem is oil. Negotiations with Tehran have stalled, attacks on shipping have resumed and Iran insists the Strait of Hormuz will remain closed unless Washington accepts its conditions. Brent settled near $89 on Tuesday as hopes of a quick settlement faded. Before the war, roughly a fifth of global oil and liquefied natural gas flows passed through Hormuz. With that artery still compromised, how confidently can markets assume the energy shock is disappearing?
That question leads directly to the bond market. The US 10-year Treasury yield has reached 4.75 percent, its highest in 18 months, while the 30-year has moved above 5.20 percent, a level last seen in 2007. The long end appears increasingly worried about inflation, fiscal deficits and the credibility of monetary policy. And therein lies a rather delicious political problem.
Trump wants lower interest rates. Treasury Secretary Scott Bessent wants lower long-term Treasury yields. In calmer circumstances, both men could reasonably expect to get their wish together. But what happens when an oil shock keeps inflation elevated?
A sufficiently dovish Fed might lower short-term borrowing costs and satisfy the White House. Yet if bond investors interpret that easing as evidence that the central bank is becoming less serious about inflation, couldn’t they demand greater compensation for holding long-term debt? The 10-year yield could then rise, delivering precisely the outcome Bessent would prefer to avoid.
And what might bring those longer yields down? Perhaps a Federal Reserve willing to demonstrate its inflation-fighting credentials by tightening policy. One suspects that would make for an interesting conversation in the Oval Office.
This is where the yield curve begins telling us considerably more about politics than a campaign speech ever could. The administration wants cheaper money ahead of November’s congressional elections. The Treasury wants manageable financing costs. The bond market wants protection against inflation. And the Fed is supposed to satisfy its mandate while pretending it cannot hear the political shouting outside the building.
Can Kevin Warsh manage that?
His appointment was always going to raise questions about Fed independence because Trump has made his preference for lower rates abundantly clear. Yet Warsh now faces circumstances considerably less convenient than the president might have imagined. Inflation remains above the Fed’s 2 percent target, energy prices are again under pressure and several policymakers have already shown greater willingness to tighten.
The latest US inflation figures (due late Wednesday Pakistan time) had not been released when this column was written. Markets were effectively treating the September Fed meeting as a coin toss between another hold and a quarter-point hike. That makes the coming data important. But does it also make Warsh’s response even more important?
If inflation surprises higher, pressure for a rate increase will grow. If it comes in softer, the Fed may have room to hold. Yet even that might not settle the matter. Would a central bank seen as reluctant to tighten simply transfer the inflation anxiety from the short end of the curve to the long end?
That is the trap.
And it arrives just as Trump has reopened his confrontation with the institution itself. His administration is again seeking to remove Fed Governor Lisa Cook, this time over unproven mortgage-fraud allegations, while questions persist about presidential contact with Warsh. Could the timing be worse for a bond market already wondering how firmly the central bank intends to defend price stability?
Perhaps this is where another unintended consequence of the Iran adventure comes into view.
A war that was presumably expected to deliver geopolitical results has already disrupted energy markets and global trade. Now uncertainty surrounding Hormuz is helping keep oil prices elevated, which feeds inflation anxiety, complicates monetary policy and leaves Washington discovering that demanding lower interest rates is considerably easier than persuading bond investors to provide them.
And none of this stays in America.
The US Treasury curve remains one of the principal channels through which global financial conditions are transmitted. Sovereign borrowing costs, corporate debt, mortgages, currencies and emerging-market financing all respond, directly or indirectly, to movements in US yields. When the long end rises and the dollar strengthens, financial conditions tighten far beyond Wall Street.
Where does that leave an oil-importing, externally financed economy such as Pakistan?
Higher crude prices threaten the import bill and inflation. Higher Treasury yields can raise the cost of external capital. A stronger dollar can pressure emerging and frontier-market currencies. Should these forces arrive together, how much room do vulnerable economies really have to manoeuvre?
Perhaps that is why the bond market deserves watching so closely. Once again, financial prices are providing an unusually candid glimpse into the contradictions confronting the world’s halls of power.
Trump wants lower rates. Bessent wants lower yields. The Fed wants credibility. The bond market wants protection from inflation. Iran wants its conditions met before Hormuz reopens.
And everyone apparently wants peace.
No wonder one market analyst recently offered perhaps the most useful advice for navigating the moment: “If you’re not confused, you’re not paying attention.”
