Investors are keeping calm, after this week's stark warnings from the Reserve Bank.

Governor Adrian Orr has left many mortgage holders reassessing their options, after lifting the OCR to 4.25 percent and warning it could peak at 5.5 percent.

He's also confirmed the bank is deliberately engineering a recession, that's likely to hit about the middle of next year.

JMI Wealth Director Andrew Kelleher told Mike Hosking while short term interest rates are rising, markets certainly haven't been caught by surprise.

He says foreign exchange, interest rates and sharemarkets have all been relatively calm about the central bank's hawkish stance.
