Walter Boyd (c.1754–1837) was a British financier.
Boyd was born in obscure circumstances in Scotland about 1754. Before the outbreak of the French Revolution he was a banker in Paris. The progress of events soon caused him to flee, and the property of the firm of Boyd, Ker, & Co., of which he was the chief member, was confiscated in October 1793. In March 1793 the firm of Boyd, Benfield, & Co. was established in London. Boyd, as the principal partner, contributed £60,000 to the common stock.
He was a supporter of William Pitt the Younger, and enjoyed his confidence. He was employed in contracting to the amount of over £30 million for large government loans, and for some time was very prosperous. He was also M.P. for Shaftesbury (1796–1802), which at the period of his election was a pocket borough of his partner Paul Benfield, who was returned along with him .
After a few years the firm got into difficulties. It had at one time seemed likely that the property seized at Paris would be restored, but the revolution of 4 September 1797 caused the overthrow of the government which had taken preliminary steps towards restitution, and the final confiscation of the property followed. In expectation of a different issue, Boyd, Benfield, & Co. had entered into arrangements which soon resulted in disaster. They obtained private help, and even assistance from government, but in 1799 the affairs of the company were put into liquidation, and Boyd found himself ruined.
He visited France in the brief interval of the Peace of Amiens (March 1802 – May 1803), was one of those detained, and was not released till the fall of Napoleon in 1814. On his return to England he was able to recover something of his former prosperity, and sat as M.P. for Lymington from April 1823 to 1830. Walter Scott met him in April 1828, and gives an account, though not accurate, of his remarkable self-sacrifice on behalf of his creditors.
Boyd died at Plaistow Lodge, Kent, on 16 September 1837.
