It is part of a wider effort from Lloyds Banking Group across the UK to help support the growth of SMEs and to help reverse the country’s widening trade deficit.
The new and ambitious export pledge which includes finance, advice and events, will see it support 5,000 first time UK exporters during 2016, and a total of 25,000 by 2020.
Graham Blair of Bank of Scotland said: “The future success of the Scottish economy hinges on small businesses looking to overseas markets for growth.
“Through this new pledge, we want to support a new legion of Scottish exporters, and ultimately to help the Scottish economy to prosper.
“We have been working in partnership with UKTI for the past year, looking at ways to boost Scottish exports, and through this commitment we hope to contribute towards supporting new exporters.”
The bank has committed to invest a total of £450m in digital technology and training, over the next three years, which will help support the commitment.
In addition, the group has trained more than 300 staff across the UK in international trade.
