@CarlosPinzón Well, very large transactions have happened in the past: http://www.coindesk.com/194993-btc-transaction-147m-mystery-and-speculation/ As for a source, this is the code in Bitcoin that checks if a value is between 0 and 21 million coins: https://github.com/bitcoin/bitcoin/blob/3081fb9a31054224759453c3ca400b9076ab8004/src/main.cpp#L944

<p>Transaction outputs are the only place we specify amounts, stored as 64-bit unsigned integers. So we can specify maximum of 92233720368.5 bitcoins in an transaction output. </p>

<p>However, there are per-output checks using <code>bool MoneyRange()</code>, when a new block is announced. This is more important, since it lowers the maximum amount that can be transacted to the 21-million figure.</p>

<p>Apart from the limited transaction size in MB, which theoretically limits the maximum amount of money a transaction can handle, is there any standardized bound?</p>

Is there a maximum amount of money a transaction can handle?

There is no limit on the per-input, per-output, fee, or total amount transacted, apart from the fact that all numbers need to be valid BTC amounts (which means not less than 0 and not more than 21M BTC).
