Corn near one-week high on US crop worries, soybeans firm

What happened: Chicago corn rose on Wednesday, trading near the previous session's one-week high, while soybeans gained and wheat was little changed. Concerns about declining US crop conditions and Black Sea grain vessel attacks supported prices. Key numbers: Corn rose 0.2% to $5.08-3/4 a bushel. Wheat added 0.1% to $7.04-3/4 a bushel. Why it matters: Harvest progress trailed analyst expectations and the five-year average, and the USDA cut its corn condition rating more than expected. Traders await the USDA's monthly supply-and-demand report on Friday.
