The banking system was sound in New Zealand and the Reserve Bank did not expect that situation to alter, governor Alan Bollard said.
"Over the past year, we have announced a number of measures that will make it easier for financial market participants to maintain liquidity during a period of financial market disruption.
"While we believe these are sufficient, we are keeping liquidity support arrangements under review and will respond as appropriate."
In the meantime, the central bank was staying in close touch with retail banks and the Government.
The Reserve Bank was monitoring current events in the financial markets closely.
The failure of the United States Congress to agree to the rescue package was a disappointment and it left parts of the financial markets in limbo until the matter was resolved.
The very short-term effects on the New Zealand market were not major, Dr Bollard said.
The Reserve Bank of Australia (RBA) injected some extra cash into the money market yesterday as banks' reluctance to lend to one another kept money-market rates stubbornly high.
The RBA sought to ease some of the strain by adding $A4.7 billion ($NZ5.62 billion) in repurchase agreements, slightly above an estimated daily need of $A4.6 billion.
The addition should keep banks' cash cushion with the RBA close to a record $A11 billion.
Like many central banks, the RBA has been generous with liquidity in recent weeks as turmoil in world markets lead commercial banks to keep hold of cash.
It was the second consecutive day the RBA had injected liquidity into the Australian banking system.
Myles Wealth Management principal Craig Myles said if the international crisis was not resolved soon, the flow-on effects would be felt in the New Zealand banking system.
The Reserve Bank statement on the New Zealand banking system was "generically correct" as the situation stood yesterday.
However, there were stresses starting to show in the system.
Some of that would come through the cost of funds but not all banks would be affected the same way.
Banks exposed to the American market would be more affected than those which were not, he said.
Bank profits would be affected.
A change in accounting standards being introduced was unlikely to affect the profit announcements likely before the end of the year.
