Thin on the left so far

None of the 9 outlets with a published leaning rating that ran this story are rated left.

This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.

The 60-day truce between the US and Iran ended on 17 August 2026. Tehran announced it would shift to a 'fully offensive' military posture, as reported by PerthNow. Oil prices rose more than US$2 on 16 August, with Brent crude futures up 0.2% to US$91.06 a barrel when trading resumed in Asia on 18 August.

US Treasury yields increased. The 10-year yield rose 0.8 basis points to 4.728%, and the 30-year yield climbed 0.6 basis points to 5.3146%, its highest level in more than two decades, according to PerthNow. Asian equity markets showed mixed results: MSCI’s Asia-Pacific index (excluding Japan) gained 0.8%, South Korea’s KOSPI rose over 3%, and Japan’s Nikkei 225 fell 0.3%.

ING analysts, quoted by PerthNow, said the US 10-year yield moving above 4.65% had previously prompted reassurances from the Trump administration about resolving the conflict with Iran. This time, they said, there were no indications of an imminent resolution.

Centre

6 rated outlets

  • The centre-rated reports agree that the 60-day US-Iran truce ended on 18 August 2026, with Iran announcing a shift to a "fully offensive" military posture. All five outlets led on the resulting rise in oil prices and bond yields. PerthNow and Channel News Asia specified Brent crude futures at US$91.06 and US$91.20 a barrel, respectively.
  • PerthNow, Channel News Asia, and WTVB’s digest included Tehran’s statement on its military posture. The two full reports quoted ING and Westpac analysts attributing market movements to the truce’s expiry and President Trump’s refusal to extend it. None of the digests mentioned the US retail sales drop or its effect on Federal Reserve rate expectations.
  • Channel News Asia and PerthNow carried the yield on the US 30-year Treasury bond reaching its highest level in nearly 20 years. Both full reports noted the US dollar index near a two-month low, while PerthNow added gold and cryptocurrency movements. hngn.com’s digest alone mentioned Trump’s threat to bomb Oman over the Strait of Hormuz standoff.

Right

3 rated outlets

  • The three right-rated digests led on the expiration of the US-Iran truce and its immediate economic effects. Free Malaysia Today’s digest noted that Asian stocks gave up early gains as Tehran threatened a 'fully offensive' military posture, with no imminent resolution in sight. The Straits Times’ digest focused on the rise in Brent crude futures to US$91.06 a barrel.
  • The West Australian’s digest highlighted the US$2 rise in oil prices on 16 August, attributing it to the stalemate in Iran refocusing traders on global supply concerns. None of the right-rated digests mentioned the specific movements in US Treasury yields or the mixed performance of Asian equity markets.

Questions about this coverage

How did the left and right cover Iran resumes offensive posture as 60-day US truce expires, lifting oil…?
Of the 9 outlets on this story carrying a published leaning rating, 0% are rated left, 67% are rated centre, 33% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 12. The sections above set out what each side emphasised, in its own terms.
Is Iran resumes offensive posture as 60-day US truce expires, lifting oil… left or right?
Too few of the outlets on this story carry a published leaning rating to say. 9 of them do, and this site does not characterise a field under 12: at that size one newsroom filing moves the share by ten points. The percentages above are the count as it stands.
Is the coverage of Iran resumes offensive posture as 60-day US truce expires, lifting oil… biased?
Iran resumes offensive posture as 60-day US truce expires, lifting oil and yields is one event reported by 12 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which side is not reporting Iran resumes offensive posture as 60-day US truce expires, lifting oil…?
When we first saw this story, outlets rated left had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
Which outlets covered Iran resumes offensive posture as 60-day US truce expires, lifting oil…?
12 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
