London and Singapore form the backbone of Asian-European finance. Many global banks maintain their two largest international offices in these cities. Insurance underwriting, commodity trading, and wealth management teams synchronise across this 8-hour gap daily.
Singapore Time is UTC+8 with no DST. Greenwich Mean Time is UTC+0, shifting to BST (UTC+1) in summer. The standard gap is 8 hours: 9 AM in London is 5 PM in Singapore. During BST the gap narrows to 7 hours.
The overlap is tighter than it appears. A 7–10 AM GMT window maps to 3–6 PM SGT, covering the last three hours of the Singapore workday. During BST, the same London hours map to 2–5 PM SGT, which is even more comfortable.
