Global Macro Transmission Mechanism
The financial system functions as an interconnected structure where changes in one segment inevitably translate into others. Asset price movements are not autonomous processes but are formed through the transmission of impulses between key variables: liquidity, cost of money, yields, and capital flows. This process constitutes the mechanism of macroeconomic transmission.
The starting point is liquidity, which determines the volume of available capital in the system. It is shaped by central bank policies – changes in interest rates, open market operations, and the expansion or contraction of the balance sheet. An increase in liquidity means that there is excess capital in the financial system that has no immediate application in the real economy and, consequently, is directed to financial markets. A decrease in liquidity, conversely, creates a capital deficit and forces participants to reduce risky positions.
The next level of transmission is the bond market, which acts as a basic channel for capital redistribution. Government bond yields reflect the cost of money in the system and expectations regarding future monetary policy. Rising yields mean an increase in the cost of financing and, as a result, a decrease in the attractiveness of risky assets. Falling yields, on the other hand, signal cheaper financing conditions and stimulate the search for yield.
Through the mechanism of the interest rate differential, the impulse is transmitted to the foreign exchange market. Capital tends to move between jurisdictions in search of higher yields, which generates demand for the respective currencies. Thus, changes in bond yields translate into the strengthening or weakening of currencies through changes in the relative attractiveness of assets denominated in these currencies. The exchange rate in this context acts not only as the price of money but also as a reflection of global capital redistribution.
The next stage is the impact on risky assets. Stocks, commodities, and other asset classes with a higher level of risk are directly dependent on the availability of liquidity and the cost of financing. In an environment of abundant liquidity and low rates, investors are forced to move along the risk curve in search of yield, which supports the growth of these assets. In the opposite situation, when liquidity contracts and rates rise, the reverse process occurs—a decrease in demand for risk and a redistribution of capital to more conservative instruments.
An important element of this mechanism is the time lags and nonlinearity of impulse transmission. The reaction of different market segments is not simultaneous: the bond market typically reacts faster, while stocks and other risky assets may show a delay. Moreover, the effect of changes can be disproportionate—minor shifts in liquidity or expectations can lead to significant changes in prices due to the effect of accumulated positions and structural imbalances.
Thus, the financial market functions as a signal transmission system in which liquidity determines the overall volume of capital, rates determine its cost, yields determine its alternative return, and the foreign exchange market determines its direction of movement. Risky assets are the final point of this process, reflecting the cumulative effect of all previous changes.
A key consequence of this approach is the shift in focus from analyzing prices as isolated values to analyzing cause-and-effect relationships. Understanding the transmission mechanism allows for the interpretation of market movements as a result of changes in underlying variables, rather than as random fluctuations. This, in turn, provides the basis for building a systemic approach to decision-making, in which price is viewed as the ultimate manifestation of deeper macroeconomic processes.
