<p>I will give you some simplified thoughts in three brief sections:</p>

<hr>

<p>The traditional view is that higher rates increase the cost of investment and increase the opportunity cost of spending (rather than saving). This places downward pressure on prices. Another way to think about this (opportunity cost part) is considering that higher rates reduce liquidity, which in turn reduces the demand for goods and services. </p>

<hr>

<p>Asset prices typically move in the opposite direction of interest rates. So, raising rates to cool inflation would actually, according to the common understanding, place downward pressure on asset prices. However, if one looks into the data, one can see that there are co-movements in asset prices and rates. These co-movements are the basis of Karadi's newest paper that is currently R&amp;R'd. However, Gali does have a paper suggesting a link between rates and asset bubbles wherein increasing interest rates can impact the short-run behavior of rational bubbles. </p>

<hr>

<p>Higher rates can encourage capital inflows. This can cause currency appreciation. This generates its own set of issues. </p>

Thanks for the reply. Why do higher interest rates dampen asset prices? It seems as though things like bonds and housing might increase (due to, perhaps, foreigners purchasing these assets) in price while things like equities would decrease (due to slowing corporate growth potential)

I also want to note something here -- there is no definitive empirical test for bubbles. The best evidence that bubbles even exist has come from laboratory experiments. Asset bubbles form consistently in certain forms of asset market experiments but not in others. Some economists will argue that bubbles do not exist. So, it is not straightforward to discuss them.

<p>Inflation, as measured by CPI, is showing the rate of change in prices for a basket of goods. If demand increases rapidly for the goods in the basket (or supply decreases), with all other things remaining equal, then under traditional economic theory inflation would rise</p>

<p>Increasing interest rates raises the opportunity cost of spending now versus saving. If more money is saved, less is spent so there is less demand for goods, less upwards pressure on prices and less inflation impact</p>

<p>This works at both the consumer and corporate/investor levels. If a company is deciding whether to invest or not it will use a discount rate which incorporates the cost of money. If interest rates go up this benchmark goes up so an investment in an asset may no longer be made if it is better on a risk adjusted basis to save the money and earn interest rather than making a risky investment or asset purchase </p>

<p>The effect is the same - less money in circulation, less being spent on goods and assets and therefore less inflation</p>

<p>Note this is all from an economics theory perspective and use of interest rates to manage inflation is a cornerstone of Monetary Economics - whether this works in practice either in the short-or long-term is a topic of debate </p>

<p>I doubt that higher interest rates that attract capital inflow into a particular currency creates an asset bubble because if the higher interest rate attracts the investment, it is usually an investment into an interest yielding security or deposit.

<p>My understanding is that by raising interest rates, domestic CPI indices are less likely to rise signicantly.

Examples of asset value calculations are at this link. en.wikipedia.org/wiki/Present_value              Higher interest rates will calculate lower asset values for both bonds and equities.

My question is about the dissemination of short term interest rates, not a simple present value calculation. My understanding is that asset prices might inflate due to a change in demand, rather than a simple change in discount rate.
