The yen intervention isn't working.
The attempt to push down long-term Treasury yields isn't working either.
And Mohamed El-Erian thinks both are symptoms of the same problem: Washington increasingly believes government policy can dictate market outcomes.
Markets are reminding it otherwise.
Japan has already sold roughly $96 billion in foreign securities in a month while defending the yen, putting additional upward pressure on U.S. yields.
Yet the yen has weakened again, creating what El-Erian agrees is essentially a vicious loop: defend the yen, sell Treasuries, push U.S. yields higher, make the carry trade more attractive, weaken the yen again.
Washington is simultaneously trying its own financial engineering.
With mortgage costs hurting voters ahead of the midterms, the administration wants lower long-term yields.
But El-Erian says Treasury lacks the “bazooka” required to overpower a market this large.
Without fixing the fundamentals, intervention becomes another Band-Aid.
And those fundamentals aren't pretty.
U.S. debt has crossed $40 trillion, doubled in 10 years, and interest payments are rising roughly 15% annually.
Meanwhile, the AI boom is creating another enormous demand for capital, forcing government, companies and households to compete for money and pushing borrowing costs higher.
El-Erian's broader warning is about “geo-economics.”
Tariffs. Sanctions. Currency intervention. Treasury intervention.
Economic tools increasingly look attractive because their costs aren't immediately visible.
But the costs don't disappear.
They accumulate.
And eventually, El-Erian warns, markets will react.
