Would cancelling all US student loan debt tank the economy a-la a subprime mortgage crisis?

Basically title - isn't it possible that cancelling all student loan debt would tank the economy? what if our debt has been packaged, sold, and speculated upon by banks a-la subprime mortgage crisis? wouldn't value just disappear?

The debt that is having a call for cancellation is federally owned student loan debt- because the government owns the debt directly, they have the power to forgive via fiat (though whatever process this fiat takes is currently a matter of political debate) and they have not resold the debt. 

Hence, it has not been "packaged, sold, and speculated upon", at least the stuff of interest.
