Interesting question, as usual!
Here are the top Lend-Lease beneficiaries:
Great Britain............$31 billion
Soviet Union.............$11 billion
France...................$ 3 billion
Other European..........$500 million
South America...........$400 million
The amount totaled: $48,601,365,000."
source: History Central
"Total lend-lease aid exceeded $50 billion, of which the British
Commonwealth received some $31 billion and the USSR received over $11
billion. Within 15 years after the termination of lend-lease,
settlements were made with most of the countries that had received
aid, although a settlement with the USSR was not reached until 1972."
Although the British Commonwealth received $31 billion in Lend-Lease
aid, it appears that there was a postwar settlement agreement that
Britain would owe around $5.2 billion plus interest. A New York
Times article from 1955 details how the British had made a $155
million payment, but still owed $4.58 billion on a debt that, at its
height, was $5.2 billion.
BRITAIN REDUCES DEBTS $137,845,431; Payment to U. S. Is Made on
Post-World War II Account -- Billions Still Owed
New York Times: Jan 1, 1955. p. 3
All indications suggest that the British government has been making
fairly regular payments on that $5.2 billion debt (plus 2 percent
annual interest) for the last five decades.
A 1966 article in the New York Times indicates that Britain had
resumed its regularly scheduled postwar payments after missing them
for three years.
BRITAIN TO MAKE 2 LOAN PAYMENTS
The New York Times. Dec 17, 1966. pg. 45,
A New York Times article from 1970 mentions that the British had made
a $188.4 million payment. The article also says that the original
loan was at 2 percent interest and was due to be repaid in 2005.
Britain Makes Payment To U.S. on Postwar Loan
New York Times: Jan 1, 1970. p. 35
That's consistent with this internet messageboard item:
"(1) Lend lease payments from the Brits were rescheduled in 1946; in
the April 2003 UK Govt budget you will see a line item that
$160million remains outstanding and will be repaid in full with
interest by June 30, 2005."
I direct your attention to:
DEBT & RESERVES MANAGEMENT REPORT 2003-04
Notice on page 15, under the heading "Bank of England," there are
"loans" of £0.4 billion.
Footnote #11 indicates those loans are "Composed of Canadian and US war debt."
The U.S. hasn't done quite so well with its other big Lend-Lease
client, the Soviet Union.
According to a New York Times article, the U.S. asked the Soviet Union
in 1947 to repay $1.3 billion of its Lend-Lease debt. The Soviet
Union offered $170 million. The issue was basically dormant until the
Soviets agreed in 1972 to partially settle the debt by buying $750
million in grain from the U.S.

The Russian Federation inherited the debt from the Soviet, and it was
still on the books to the tune of $600 million as of a few years ago.
