Treasury’s Bond Intervention Is Here. What Comes Next?

As this intervention was never large enough to reverse the rise in long-term yields, I am now leaning towards the thesis that Treasury and the Fed are setting the stage for a regime similar to the one we saw under Yellen, especially after listening to Bessent’s interview yesterday.

Was the Treasury Market Intervention Worth It?

Treasury officially doubled the maximum size of its liquidity-support buybacks in the 10–20Y and 20–30Y sectors from $2bn to at least $4bn per operation, effective from September 9 through November 4.

The initial reaction was exactly what you would expect. Long-term yields fell sharply, the dollar weakened and equities and gold moved higher. But yields have since pushed back up, which reinforces my view that the intervention itself was never large enough to reverse the broader rise in long-term yields.

So I think the more important question is what Treasury is actually trying to set up.

The Yellen Playbook

A refresher on Yellen’s regime.

In 2023, Yellen slowed the increase in longer-dated issuance and financed more of Treasury’s borrowing through short-term bills.

Sound familiar?

To be precise, Treasury was still increasing coupon issuance, but it deliberately increased the longer-dated tenors at a more moderate rate. That reduced the amount of additional duration the market suddenly had to absorb.

Yellen then launched the regular Treasury buyback programme in May 2024, initially at up to $2bn per operation for nominal coupon securities.

That is the programme Bessent has now increased in the long end to $4bn.

The broader policy mix helped suppress pressure on the term premium, while the huge reverse-repo balance meant money-market funds could absorb additional Treasury bills without the same drain on bank reserves.

Once the Fed also became more dovish, both parts of the yield equation started moving lower together.

If you are not familiar with the yield equation:

Long-term yield = expected path of Fed rates + term premium

The Fed mainly controls the first part.

Treasury can influence the second through the maturity mix of issuance and the amount of duration the private market has to absorb.

Once the Fed turned dovish in late 2023, expectations for future policy rates fell while Treasury’s issuance strategy helped limit pressure on the term premium.

Both sides moved together.

That was supportive for bonds, equities and broader liquidity.

Treasury and the Fed Could Be Recreating That Setup

If you’ve been following me for a while, you know my models still suggest the market has become too hawkish on the Fed.

And I don’t think we even need an aggressively dovish Fed for this thesis to work.

If the Fed simply comes out less hawkish than currently priced, we could see both parts of the yield equation start moving together again:

Lower expectations for future policy rates + lower term-premium pressure from reduced duration supply.

Basically, Treasury and the Fed could be recreating parts of the Yellen regime.

That combination would be supportive for bonds, equities and broader liquidity, much like the setup we saw in late 2023.

The Problem: Yellen’s Liquidity Buffer Is Gone

There is one major difference though.

The buffer Yellen had to absorb bill issuance without draining bank reserves — the Fed’s reverse-repo facility — is basically no longer there.

That means Treasury cannot simply shift huge amounts of funding towards bills and expect money-market funds to pull hundreds of billions of dollars out of the RRP like they could in 2023.

However, this is where things get interesting.

The Fed is already conducting reserve-management purchases, predominantly through Treasury bills and other short-term securities, to maintain an ample level of reserves.

So rather than saying Treasury would force the Fed to start buying bills, I think the more accurate thesis is that heavier bill issuance could contribute to reserve pressure and give the Fed a reason to maintain or potentially increase reserve-management purchases.

The end result can look very QE-like from a liquidity perspective:

Treasury relies more heavily on bills → reserve pressure increases → Fed buys short-dated Treasuries to maintain ample reserves → reserves and liquidity are supported.

Technically, however, it is not QE.

QE is designed to remove duration and deliberately loosen broader financial conditions. Reserve-management purchases are designed to maintain sufficient reserves and control short-term rates.

But from the perspective of balance-sheet expansion and liquidity, you can see why markets may treat the combination similarly.

What Happens If the Fed Stays Hawkish?

This is where Bessent’s comments yesterday become important.

Even if we get a more hawkish Fed and Waller does not play ball, pushing long-term yields higher again, Bessent has said that Treasury is prepared to increase the operations even further.

Bessent says Treasury bond buybacks could increase further

That does not mean Treasury can simply control the 30Y yield.

It can’t.

The $4bn operations themselves are tiny compared with the size of the Treasury market and do nothing to remove the underlying fiscal, inflation or monetary-policy risks driving yields higher.

But it tells us Treasury is increasingly willing to lean against disorderly moves in the long end.

And if the response involves more reliance on short-term bills alongside larger long-end buybacks, then the interaction with bank reserves and Fed reserve management becomes increasingly important as the Fed might be forced to buy bills to stablelyze.

This is why I think focusing only on whether the first $4bn intervention pushed yields permanently lower misses the bigger picture.

The intervention itself is small. The policy direction is much more important.

Leveraged Funds Could Add Fuel to a Bond Rally

Now, to tie things up, leveraged funds have been building large shorts in Ultra Bond futures.

But there is an important distinction here.

A significant portion of those futures shorts is part of the so-called Treasury basis trade:

Long cash Treasury + short Treasury futures + repo financing

So this cannot simply be interpreted as hedge funds making a massive directional bet that long-term yields are going higher.

The futures short often hedges the cash Treasury position.

However, they can still get squeezed if we get a more dovish Fed or weaker macro despite the trade being hedged.

This is because Treasury futures are one of the fastest and most liquid ways to add duration after a dovish surprise.

So imagine the Fed surprises dovishly.

Treasury futures start rallying quickly.

The fund then starts losing money on its leveraged futures short.

If the move becomes sufficiently aggressive, margin requirements rise and the economics of the basis trade deteriorate.

Some funds then reduce the trade.

And reducing the trade means buying back the short Treasury futures.

That can make futures rally even more.

Basically:

Dovish Fed / weak macro → Treasury futures rally → leveraged shorts come under pressure → shorts are covered → futures rally further.

The important thing is that this is a potential amplifier, not the original reason bonds would rally.

The original catalyst still has to come from rates, macro or Treasury policy.

TLDR

Treasury’s intervention itself was never large enough to permanently reverse the rise in long-term yields.

The more important development is that Treasury and the Fed may be setting up a liquidity regime similar to what we saw under Yellen.

Bessent is reducing pressure on the long end through larger buybacks and potentially more reliance on short-term funding. If the Fed becomes even slightly less hawkish than currently priced, both parts of the long-term yield equation could begin moving lower together.

The major difference is that the huge RRP buffer from 2023 is gone.

With the RRP buffer largely gone, a heavier shift towards bill issuance could drain reserves more directly and potentially give the Fed a reason to restart reserve-management purchases or rely more heavily on repo operations.

Add the huge leveraged-fund short positioning in Treasury futures and a sufficiently dovish Fed or weak macro surprise could force some of those positions to unwind, making a bond rally considerably more aggressive.

The combination would be supportive for bonds, equities, gold and broader liquidity.
