Lead

The South Korean won weakened against the U.S. dollar on Monday and Tuesday, as foreign investors continued to sell local stocks, according to Yonhap News Agency. The won closed at 1,429.8 won per dollar on Monday, down 5.8 won from the previous Friday's onshore close, and at 1,432.5 won on Tuesday, down 2.7 won from the previous day's stock trading close.

Coverage comparison

Yonhap News Agency reported on both trading days, attributing the won's weakness to foreign investors' net selling of local stocks. On Monday, the won opened at 1,437.5 won per dollar and strengthened to as high as 1,425 won, marking its strongest level since Feb. 26, before closing lower. On Tuesday, the won opened at 1,431.8 won per dollar and stayed flat, with the dollar remaining weak after the United States and Japan confirmed their joint market intervention last week.

The reports also noted the influence of oil prices and U.S.-Iran relations. On Monday, oil prices declined amid fresh optimism over prospects of talks between the U.S. and Iran. On Tuesday, oil prices gained as U.S. President Donald Trump claimed that talks with Iran were underway, stressing that the two sides were discussing the reopening of the crucial Strait of Hormuz, although Tehran denied any plans for negotiations with Washington.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
