Christine Hunsicker, former CEO of CaaStle, gave investors falsified documents that overstated profit and cash reserves

A fashion tech founder was sentenced to five years in federal prison for her involvement in a $300m “fraud scheme” spanning from 2019 to 2025, the Manhattan US attorney’s office announced on Thursday. Christine Hunsicker, 49, was also sentenced to three years of supervised release.

Hunsicker, the founder and ex-CEO of CaaStle Inc, had pleaded guilty this March to one count of securities fraud in relation to a scheme that “defrauded hundreds of investors”, authorities said. Her attorneys did not immediately respond to a request for comment.

• ‘Starve the beast’? The $40tn cost of Republicans’ false promises to cut spending

Government borrowing costs around the world have surged to the highest levels in decades amid growing fears over US bond market turmoil.

Anxiety about Donald Trump’s handling of the US economy, and concern that the US president’s war with Iran is driving up inflation, are causing a sell-off in the US bond market.

The enormous US debt under Trump will hobble the next Democratic administration – just as the GOP planned

• Why is the Trump administration causing turmoil in the bond markets?

You could pin the US’s staggering $40tn in government debt to Donald Trump’s Keystone Cops-style governance. Tariffs he sold as a new source of revenue were struck down by the supreme court, forcing the government to return tens of billions of dollars to importers. Elon Musk’s “department of government efficiency” (Doge), ostensibly created to stop wasteful government spending, decimated federal programs and probably killed millions of children, but did nothing to close the budget deficit. The burst of inflation following Trump’s misguided adventure in Iran sharply raised the cost of serving the government’s obligations.

Yet as the federal debt hits an all-time high, up from about $35tn when Trump took office less than two years ago, it is worth noting that the US’s gargantuan indebtedness is in fact the product of a longstanding Republican strategy that took shape well before Trump could even dream about gold-plating the White House. It was called “starve the beast”.
