A US debt crisis will arrive sooner as banking turmoil hits the economy and federal revenue, strategist says

• Tighter lending due to the banking crisis will slow the economy, resulting in less federal revenue.
• So Congress will have to lift the debt ceiling sooner than anticipated, a Stifel strategist said.
• "Receipts to the government — all those cash flows — are probably going to slow." 

The banking turmoil could accelerate urgency on the debt ceiling, according to Brian Gardner, Stifel's chief Washington policy strategist.
