The FTSE rose 2.18% to 6,800 shortly after opening today in its second consecutive day of growth as central banks around the world raised hopes of injecting millions of pounds into the economy to help manage the fallout from the coronavirus epidemic.
The blue-chip index increased ahead of a G7 central bank conference call of governors and finance ministers that is expected to deal with the outbreak, although a source at the group said it would not detail any immediate steps boost growth.
These could include lowering interest rates to encourage borrowing and investing or quantitative easing, where central banks inject money directly into the economy.
At 8.30am, the domestically-focused FTSE 250 also rose 2.23% to 19,732, with rises led by UK marketing firm 4imprint Group, which jumped 13% after saying it had so far seen minimal impact from the health crisis.
