TAIPEI, May 27 (Reuters) - Taiwan is considering boosting a loan facility to help small and medium sized firms hit by the COVID-19 pandemic, and may extend it to individuals, with almost $20 billion available, sources briefed on the matter told Reuters. The central bank last year made T$300 billion ($10.80 billion) available to help SMEs cope with the impact of the coronavirus, which is now surging in parts of Taiwan after months of being well under control.
