U.S. Treasury yields hold while Aussie yields retreat after 2011-era peak run up

September 29, 2026 7:19 AM

Investing.com - Global sovereign bond yields remained anchored near multi-year peaks on Tuesday, driven higher by persistent geopolitical risk in energy markets and reinforced central bank hawkishness across major economies.

U.S. Treasury yields held near record highs after President Donald Trump’s rejection of an Iranian ceasefire proposal aimed at unblocking the Strait of Hormuz sent crude oil past $106 a barrel, sharpening fears of a sustained cost-push inflation spike.

The benchmark U.S. 10-year Treasury yield held at 5.230% - its highest level since July 2007 - while the long-dated 30-year Treasury yield hovered at 5.556%, consolidating around its highest level since 2004.

At the policy-sensitive short end of the curve, the two-year Treasury yield held near 4.956%, its elevated level since May 2024.

Aussie debt pulls back after RBA delivers expected hike

In Asia-Pacific markets, the 10-year Australian government bond yield fell to 5.377%, marking its sharpest single-day decline in nearly two months.

The pullback represents a breather after Australian borrowing costs touched their highest levels since 2011 during the previous session in anticipation of monetary policy tightening.

The Reserve Bank of Australia raised its official cash rate by 25 basis points to 4.60% - a 15-year high - marking its fourth rate increase this year as persistent domestic cost pressures and global energy shocks forced policymakers to act.

Fed speakers reinforce hawkish policy outlook

Across the Atlantic, a chorus of Federal Reserve officials reinforced the higher-for-longer rate narrative, dampening hopes for near-term monetary easing.

Federal Reserve Governor Lisa Cook warned that inflation pressures are likely to persist in the coming months, citing compounding demand from the booming artificial intelligence buildout and elevated global crude oil prices as structural drivers.

Her comments align with recent hawkish guidance from regional Fed presidents, leading money markets to now price in a nearly 70% probability of another 25-basis-point rate increase at the Fed’s upcoming October meeting.

Fixed-income trading desks are closely monitoring further central bank addresses scheduled for later in the session, including remarks from Fed Governors Michelle Bowman and Michael Barr, Chicago Fed President Austan Goolsbee, and Bank of England Monetary Policy Committee member Catherine Mann.

PCE and nonfarm payrolls in view

Market participants are focused on Wednesday’s August Personal Consumption Expenditures (PCE) price index - the Fed’s preferred inflation gauge - followed closely by Friday’s September nonfarm payrolls report.

Firm prints across both releases are expected to solidify Fed rate-hike expectations, keeping global debt curves under persistent upward pressure heading into the final quarter.
