Here's a snip from a NYT article on the same topic.
>>>They appear to be balking over a significant problem: Mr. Trump does not have enough liquidity to obtain the bond. To offer a bond of this size, the companies would require Mr. Trump to pledge more than $550 million in cash, stocks and bonds as collateral — a sum he simply does not have.
Although the former president boasts of his billions, his net worth is derived largely from the value of his real estate, which bond companies rarely accept as collateral. Mr. Trump has
more than $350 million in cash, a recent New York Times analysis found, far short of what he needs. . . .
He might have to post an appeal bond worth more — possibly above $500 million, to reflect the interest he will owe — in order to prevent Ms. James from seizing his assets on March 25. . . . The looming deadline could not come at a worse time for Mr. Trump. Just last week he finalized a
$91.6 million bond in a defamation case he recently lost to the writer E. Jean Carroll, a costly deal that drained him of precious cash.<<<
Donald J. Trump’s lawyers said in a court filing that he faces “insurmountable difficulties” as he tries to raise cash for the civil fraud penalty he faces in New York.

Trump previously boasted in a deposition that he had in excess of $400 million in cash.
>>>In an
April 2023 deposition, Trump volunteered that he had “substantially in excess of 400 million in cash.”
“Developers usually don’t have cash. They have assets, not cash,” Trump said. “We have, I believe, 400 plus and going up very substantially every month.”
Trump added later that, despite the legal fees he was facing, “I have over 400 — fairly substantially over $400 million in cash. That’s just cash. That’s just cash.”<<<
If I didn't know better, I'd say it almost looks like Trump might have been lying
