Asian markets rose on 20 August 2026 after the US Treasury Department announced it would at least double the size of planned purchases of longer-term government debt. The move pushed bond prices higher and yields lower, easing pressure on equities.
South Korea’s benchmark Kospi surged 6.1% to 6,858.91, recovering from a 5.8% drop the previous day. Samsung Electronics climbed 9.7%, and SK Hynix jumped 14.1% after announcing a share buyback plan. Japan’s Nikkei 225 gained 1.3% to 66,178.26, reversing earlier losses. Japan reported a third consecutive monthly trade deficit in July, with both imports and exports at record highs.

What the coverage left out
None of the right-rated digests mentioned the 6.1% gain in South Korea’s Kospi or the 1.3% rise in Japan’s Nikkei 225. 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.

How each side covered it
Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.
Left
7 rated outlets
- 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
4 rated outlets
- 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
1 rated outlet
- 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.

- What did the US Treasury announce on 20 August 2026?
- The US Treasury Department said it would at least double the size of planned purchases of longer-term government debt.

- 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?
