Not huge rush to tighten; economy clearly not overheating
Increase in sentiment not yet translated into 'hard' data, Q1 U.S Gdp may be a bit weaker

Trimming balance sheet a 'substitute' for rate hikes; could 'pause' raising rates at that time
Likely not at stage where there is great urgency to tighten policy
