The centre-rated digests omitted the geopolitical context of the oil price rise and the stalled US-Iran negotiations. The left-rated digests, while carrying the core facts, did not include the trade deficit reported by Japan in their summaries. ## Who covered it Shares of the 12 covering outlets with a published leaning rating: - Left: 58% (7) - Centre: 34% (4) - Right: 8% (1) 1 of 13 covering outlets carried no usable leaning rating and were excluded from those percentages.

Most recently checked 2026-08-20T07:00:26.578Z. ## How the sides framed it ### Left - The left-rated reports led on the US Treasury’s debt buyback announcement and its immediate impact on Asian markets. The Associated Press, whose full report was printed, described the move as easing pressure on share prices by pushing bond prices higher and lowering yields. It quoted the 6.1% gain in South Korea’s Kospi and the 1.3% rise in Japan’s Nikkei 225, along with the fall in US Treasury yields. - The AP report also noted the role of geopolitical tensions, stating that oil prices rose slightly due to little progress in US-Iran negotiations. It included the trade deficit reported by Japan and the performance of individual stocks, such as Samsung Electronics and SK Hynix. The digests from left-rated outlets carried the same core facts: the Kospi’s 6.1% gain, the Treasury’s announcement, and the rise in US futures. ### Centre - The centre-rated digests and reports focused on the market movements and the Treasury’s debt buyback plan. WKMG, which carried the full AP report, led with the Kospi’s 6.1% gain and the Nikkei’s 1.3% rise. It included the same details on bond yields, oil prices, and the performance of individual stocks as the AP report. - The digests from centre-rated outlets repeated the key figures: the Kospi’s rebound, the Treasury’s announcement, and the rise in US futures. None of the centre-rated digests mentioned the geopolitical context of the oil price rise or the stalled US-Iran negotiations. ### Right - The single right-rated digest, from India Today, led on the easing of bond yield pressure following the Treasury’s debt buyback. It described the move as calming investors across equities but noted that firmer oil prices kept geopolitical worries in view. The digest did not include specific figures for the Kospi’s gain or the Nikkei’s rise. ## Factuality profile of the covering outlets These are published factuality ratings of the outlets, not a verdict on whether this story or its claims are true. - mixed: 1 - high: 5 - unknown: 3 - veryHigh: 4 ## Verification scope This page compares coverage and scores the source reporting.

This move was intended to push bond prices higher and lower yields, easing pressure on equities. The announcement led to a fall in the yield on the 10-year Treasury to 4.64% from 4.71%. **How did Asian markets react to the Treasury’s announcement?** Asian markets rose on 20 August 2026. South Korea’s Kospi surged 6.1%, recovering from a 5.8% drop the previous day. Japan’s Nikkei 225 gained 1.3% to 66,178.26. The move also pushed bond yields lower across the region, including in Japan, where the 10-year government bond yield fell to 2.83%. **What was the impact on oil prices?** Brent crude oil prices rose 0.3% to $91.90 a barrel on 20 August 2026. The rise was attributed to little progress in US-Iran negotiations over the ongoing war, which kept geopolitical tensions in view. Oil prices had been trading at roughly $72 per barrel before the war. --- MediaBias News — https://mediabias.news.
