SEOUL, Dec 16 (Reuters) - Round-up of South Korean financial markets: ** South Korean shares ended at a record high on Wednesday, buoyed by U.S. coronavirus stimulus hopes and vaccine rollouts, offsetting concerns over a record surge in local cases. The won weakened, while the benchmark bond yield rose. ** At 06:30 GMT, the benchmark KOSPI rose 14.97 points, or 0.54%, to close at 2,771.79. ** Top U.S. congressional leaders started a second meeting on Tuesday to try to end a months-long standoff on coronavirus relief.

** Investors also cheered the South Korean prime minister’s pledge to secure more hospital beds to handle a record surge in coronavirus cases.

** Hopes for additional U.S. stimulus boosted shares but uncertainty over Federal Reserve policies kept gains in check, said Seo Sang-young, an analyst at Kiwoom Securities.

** Moderna’s COVID-19 vaccine appeared set for regulatory nod this week, after a U.S. Food and Drug Administration staff endorsed it as safe and effective in documents released Tuesday.
