The Fed will upset the rebalancing of oil markets if it misreads the current sell-off as weakness in oil demand.
The U.S. corporate re-leveraging cycle is far more advanced than is widely believed. Corporate health looks only mildly better excluding the troubled energy and materials sectors. Mushrooming leverage ratios are not restricted to junk issuers either.
The declining correlation between risk assets and Treasury yields suggests that the market perceives monetary policy to be overly restrictive. Historically, this has led the FOMC to adopt a more dovish policy stance.
With inflation expectations declining alongside asset prices in almost every major economy, central banks can at least not make things worse by being more hawkish than necessary.
Equity selloff alone will not catch the Fed's eye unless there is an outright crash.
