Taking a look at recent ECB term deposit rates (the 7-day term deposits used to sterilize SMP liquidity) one will observe that rates have expanded somewhat from 1bp to 4-5bp (the latest auction settled around 5bp):
Total amount of bids has also fallen below €300bn (with SMP liquidity around €206bn). This indicates that overall excess liquidity has fallen considerably (based on the term deposits auctions to lower than €100bn) and is pushing short-term rates higher. This is reflected on overnight repo rates with the Eurex GC Pooling EUR Funding Rate climbing to 4-5bp. LTRO repayments and lower Target2 balances have started having an impact on money market rates. The latest auction only had €254bn in bids and is a good indicator of available funds in the Euro money market.
Falling excess liquidity will start pushing money market rates closer to the cost of funds (currently 75bp). Unless the latter is lowered by the ECB it is possible that money market lenders will start avoiding long repo maturities and focus on short-term deals (overnight/weekly). It also points to a higher probability of an ECB rate cut in the immediate future.
