Global Bond Markets Are Outperforming U.S. Treasuries as Oil Prices Cap Inflation Fears

The Setup

Two things happened this past week that should not have worked in bonds' favor — and yet they did.

U.S. GDP came in above expectations. The Fed's preferred inflation gauge, the PCE index, printed its highest reading since October 2023, according to CNBC. Both data points would normally send bond prices lower and yields higher. Instead, the 10-year Treasury yield fell below 4.4%, and the iShares 20+ Year Treasury Bond ETF (TLT) gained roughly two-thirds of a percent, extending a 5% rise since its low the previous month.

The explanation, according to Phil Streible, chief market strategist at Blue Line Futures, is crude oil. Futures fell roughly $10 from the prior Friday's high. Lower oil undercuts energy-driven inflation, which reduces pressure on the Fed to act aggressively.

"It definitely looks bearish and the curve has flattened out a little bit," Streible told CNBC. "I don't see oil in the 50s but it could get comfortable in the 60-65 range."

Options Flows Back That Reading

Options traders appear to agree. On Friday, the oil ETF (USO) saw about 30% more puts traded than calls, according to ThinkOrSwim data cited by CNBC. Of the $114 million premium traded in the fund, $81 million was tied to calls, SpotGamma data show — meaning the bulk of premium was not defensive put-buying, but rather call activity, with put-selling the least popular directional trade.

In TLT, the picture was more nuanced. More puts than calls traded, but put-selling was the highest-volume directional trade. One notable transaction: the simultaneous sale of 11,000 80-strike puts and 44,000 55-strike puts, a trade that collected roughly $2.6 million in premium, per SpotGamma data reported by CNBC. Selling puts signals the seller does NOT expect a steep drop in price.

Streible's read: "We probably saw the peak in CPI inflation and when Warsh sees inflation come down I'd think they go from hawkish to neutral, or maybe dovish."

That's a reference to Fed Chair Kevin Warsh, who told reporters earlier this month that the central bank would spend more time developing internal task forces than speculating publicly on the rate path ahead.

The International Angle

While the U.S. market held its ground, George Bory, chief investment strategist in fixed income at Allspring Global Investments, is making the case that the better opportunity is overseas.

His argument is structural. The European Central Bank raised its benchmark rate 25 basis points to 2.25% on June 11, its first hike since September 2023. The Bank of England and Australia's central bank are in similar tightening postures. Markets have priced in further moves. Bory thinks that creates real yield opportunities that U.S. investors are systematically ignoring.

"Bond markets everywhere have rushed to price inflation," Bory told CNBC's 'ETF Edge.' "Places like the UK, certainly across Europe, even places like Australia — we've seen a material run-up in central bank tightening expectations."

His specific recommendation: short-to-intermediate duration government bonds in developed markets outside the U.S., blended with some U.S. duration exposure. The logic is portfolio diversification across different rate cycles, not a wholesale abandonment of Treasuries.

Steve Laipply, global co-head of iShares Fixed Income ETFs at BlackRock, made a parallel point to CNBC, citing European fixed-income securities that currently offer lower risk profiles alongside higher yields than their U.S. equivalents.

The Case for Staying Put

Currency risk is real. A U.S. investor buying European government bonds earns the yield in euros. If the dollar strengthens, those returns erode when converted back. Historically, unhedged international bond exposure has delivered mixed results for American retail investors precisely because of this dynamic. Hedging costs money, and in a tight-yield environment, it can consume much of the advantage.

Bory is aware of this. His framing is not "dump Treasuries" but "mix in international duration." That's a more defensible position, but it also means the incremental benefit for a cautious investor may be modest rather than transformational.

The Fed's own paralysis cuts both ways. The CME Group's FedWatch gauge as of late Friday puts a 78% probability on a Fed rate hike in December, dropping to 68% for January 2027, according to CNBC. If the Fed does hike, U.S. bond prices face fresh pressure, which would validate the case for diversifying abroad. But if oil stays soft and inflation cools further, the Fed may stay on hold longer, keeping Treasuries stable and reducing the urgency of the international shift.

What's Actually Unresolved

Whether the oil-driven inflation reprieve is durable remains unclear. Streible thinks crude can settle in the $60-65 range. Options flow suggests traders are not rushing to bet against that. But oil is notoriously volatile, and a geopolitical disruption could reverse the picture in days.

If oil rebounds and the next PCE print stays hot, Warsh's "task force" posture becomes untenable. A Fed forced to hike into a slowing economy would be a different environment entirely, one where both the "stay in U.S. Treasuries" camp and the "go global" camp would need to recalibrate.

The CME FedWatch December rate-hike probability of 78% is the number to watch when next month's inflation and employment data land.
