There's no clear sign of a US credit crunch yet, a top Fed official says

• There's no clear signs of a US credit crunch yet, according to Fed official John Williams. 
• We haven't seen any clear signs yet of credit conditions tightening and we don't know how big those effects will be," he said. 
• The collapse of SVB and Signature Bank has stoked fears that lending standards to obtain a loan will become harder. 

There's no clear sign of a credit crunch in the US yet, the president of the New York Federal Reserve has said — even as his own bank's survey found Americans are already feeling the squeeze.
