NEW YORK, April 25 (Reuters) - U.S. President Donald Trump bought at least $51 million worth of bonds in March, financial disclosures released on Saturday showed, with purchases spanning several sectors.

Forms published by the U.S. Office of Government Ethics indicate that Trump conducted 175 financial transactions last month. The forms do not include the exact values of each sale or purchase, but rather a range of values for each transaction.

Most of the assets that could be disclosed were municipal bonds issued by states, counties, school districts, and other entities with ties to government agencies or public-private partnerships.

His 26 largest transactions, ranging in value from $1 million to $5 million, were mostly municipal bonds or U.S. Treasury bonds, but two of the listed deals were purchases of corporate offerings from Wirehauser and General Motors. He also invested in an exchange-traded fund that tracks a high-yield bond index.

Trump bought corporate bonds in the energy, technology, healthcare, and financial services sectors from issuers including Constellation Energy, Occidental Petroleum, Broadcom, Nvidia, MetaPlatforms, Microsoft, and banks such as Citigroup, Goldman Sachs, and JPMorgan Chase, as well as Boeing.

The maximum total value of Trump's bond purchases across all asset classes is approximately $161 million.
