Donald Trump has bought more than $US100 million ($155 million) in company, state and municipal bonds since taking office in January, new documents show.

The latest disclosures posted by the US Office of Government Ethics also reveal the US president made more than 600 financial purchases since January 21, the day after he was inaugurated for his second term.

The August 12 filing does not list exact amounts for each purchase, only giving a broad range.

Among Mr Trump’s purchases are corporate bonds in banks such as Citigroup, Morgan Stanley and Wells Fargo, as well as in other companies including Meta, Qualcomm, Home Depot, T-Mobile USA and UnitedHealth Group.

Other debt purchases include various bonds issued by cities, states, counties and school districts as well as gas districts, and other issuers.

The holdings cover areas that could benefit from US policy shifts under his administration.

Mr Trump, a businessman-turned-politician, has said he has put his companies into a trust managed by his children.

The White House on Wednesday did not immediately respond to a request for comment from Reuters.

Income flows to US president despite trust

It follows the release of Mr Trump’s financial disclosures for the 2024 calendar year in June, which showed the then-Republican presidential nominee earned more than $US600 million ($933 million) in income.

That included from crypto, golf clubs, licensing and a number of other ventures.

Despite having put his companies into a trust, the disclosure also showed that his income from various sources still ultimately accrued to the president.

That fact has opened the US president up to accusations of conflicts of interest.

A Reuters calculation shows the president has reported assets worth at least $US1.6 billion ($2.47 billion) overall.

Mr Trump’s three golf-focused resorts in Florida — Jupiter, Doral and West Palm Beach — and his private members’ club at Mar-a-Lago generated at least $US217.7 million ($337 million) in income.
